ISF 10+2 Filing Guide for China–U.S. Ocean Shipments A Fulfillment-First Playbook for Ecommerce Inventory, FBA Inbound Timing & U.S. Port Hold Avoidance WinsBS Research – Michael Updated December 2025 TL;DR Importer Security Filing (ISF 10+2) is an advance cargo security filing required for U.S.-bound ocean freight. In ecommerce, ISF is not “customs paperwork.” It is a fulfillment gate: if ISF data is late, inconsistent, or amended after vessel loading, inventory may be physically at a U.S. port while still being operationally blocked—causing FBA check-in delays, inventory availability gaps, missed inbound appointments, and lost sales windows. Official CBP overview: Importer Security Filing “10+2”. This article is written for ecommerce operators shipping from China to the United States by ocean freight, including Amazon FBA sellers, direct-to-consumer (DTC) brands, and crowdfunding teams. It explains how ISF interacts with purchase orders, factory data, booking discipline, and warehouse receiving—so your inventory becomes sellable on time, not “arrived but unusable.” If you want an inbound workflow check (data discipline, cross-border readiness, inbound scheduling), Get Started for Free or contact the team: Talk to WinsBS. If your China–U.S. ocean shipment is showing “Arrived” but: Amazon FBA inbound cannot be checked in Inbound appointments keep getting pushed out Your 3PL says the container cannot be released yet then the issue is often not port congestion and not warehouse capacity. In ecommerce fulfillment, the missing control is frequently Importer Security Filing (ISF 10+2)—specifically, whether the inbound data story was stable before vessel loading. Contents Fast Answers: ISF 10+2 for Ecommerce Why Ecommerce Shipments Say “Arrived” but Fulfillment Has Not Started What Is Importer Security Filing (ISF 10+2)? ISF as a Fulfillment Gate (Not a Customs Form) FBA vs DTC vs Crowdfunding: How ISF Failure Breaks Each Model Importer of Record Responsibility in Ecommerce Structures ISF-10 Data Elements Explained with Ecommerce Data Sources The “+2” Carrier Data Elements: What Sellers Must Still Watch ISF Timeline: What “24 Hours Before Loading” Actually Means FCL vs LCL vs Multi-SKU: Where ISF Risk Explodes High-Frequency ISF Failure Modes (Case Cards) ISF Penalties vs Fulfillment Loss: The Real Cost Model ISF vs AMS vs Customs Entry — Fulfillment Control Comparison Fulfillment-First ISF Checklist (Copy/Paste) People Also Ask: Short Answers Final Recommendation: Build ISF Into Inbound Execution FAST ANSWERS: ISF 10+2 FOR ECOMMERCE What is Importer Security Filing (ISF 10+2)? Importer Security Filing (ISF 10+2) is an advance security filing required for U.S.-bound ocean freight. It requires ten importer-provided data elements and two carrier-provided data elements to be submitted to U.S. Customs and Border Protection before vessel loading. Official CBP overview: ISF 10+2. When must ISF be filed? ISF is generally required no later than 24 hours before cargo is loaded on the vessel at the foreign port. Do not interpret this as “24 hours before the ship departs.” CBP help article: When to submit ISF. Why do ecommerce sellers feel ISF problems at FBA check-in or warehouse receiving? Because ISF is a pre-fulfillment gate. If ISF data is late, inconsistent, or amended after vessel loading, the shipment may be flagged for review and operationally delayed at the exact moment you need to schedule drayage, inbound appointments, and inventory availability. Who is responsible for ISF in practice? The Importer of Record (and/or the ISF importer depending on cargo type and filing structure) bears responsibility. A freight forwarder or customs broker may transmit the filing, but responsibility and downstream fulfillment risk do not disappear. Reference: CBP ISF FAQ: ISF 10+2 FAQs Download CBP FAQs PDF. What is the most common ecommerce ISF mistake? Treating ISF as “broker paperwork” instead of inbound execution data—especially inaccurate manufacturer identity, inconsistent ship-to party, and last-minute amendments after vessel loading. WHY ECOMMERCE SHIPMENTS SAY “ARRIVED” BUT FULFILLMENT HAS NOT STARTED China → U.S. ocean freight in ecommerce has a recurring failure pattern: the container is physically present at a U.S. port, but the business experiences the shipment as if it is “missing.” This is not a contradiction. It is a system mismatch. Ecommerce fulfillment does not start when a vessel arrives. Fulfillment starts when inventory becomes operationally usable: when drayage can be scheduled, inbound appointments can be confirmed, receiving can be executed, and the inventory record can be trusted. If any upstream control blocks those actions, you get the most frustrating state in cross-border logistics: arrived but unusable. Many sellers misdiagnose this state as port congestion, warehouse capacity, or “random inspection.” Those can be real contributors, but for ecommerce shipments the decisive root cause is often the same: the inbound data that proves identity, origin, and routing was not stable at the moment ISF needed it. In other words, the problem is not the container. The problem is the inbound proof that the container should be allowed to flow into the fulfillment system. Fulfillment-first framing: ISF 10+2 is not a form that “finishes customs.” It is a control that helps determine whether your shipment can proceed to appointment booking, receiving, and inventory availability without disruption. WHAT IS IMPORTER SECURITY FILING (ISF 10+2)? Importer Security Filing (ISF 10+2) is an advance cargo security filing required for non-bulk cargo shipments arriving in the United States by vessel. It requires the electronic transmission of specific data elements to U.S. Customs and Border Protection (CBP) prior to vessel loading. CBP’s official program page provides the baseline definition and scope: Importer Security Filing “10+2”. From a fulfillment execution perspective, Importer Security Filing (ISF 10+2) functions as a pre-entry control gate rather than a customs form. If the ISF data story is unstable at loading time, downstream inbound execution becomes unpredictable—even when the vessel arrives on schedule. “10+2” means: 10 data elements provided by the importer (or the importer’s nominated agent) that describe the seller-buyer relationship, factory identity, origin, classification, and consolidation details. 2 data elements provided by the ocean carrier: vessel stow plan data and container status messages. ISF applies to U.S.-bound cargo by vessel, including shipments moving to U.S. ports for direct discharge as well as certain transit cargo structures depending on the filing

Complete FBA Prep Guide: Labeling, Packaging & Compliance A U.S.-First Playbook That Also Works for Cross-Border Sellers Shipping into Amazon FBA (Updated Dec 2025) WinsBS Fulfillment – Maxwell Anderson Updated December 2025 TL;DR FBA prep is the labeling, packaging, and compliance work required so Amazon can receive, store, pick, and ship your inventory without manual intervention. Most inbound failures come from barcode conflicts, missing carton/pallet identifiers, and packaging that opens, leaks, breaks, or separates in warehouse handling. Starting January 1, 2026, Amazon states it will no longer offer prep and item labeling services for U.S. FBA shipments—so every unit must arrive fully prepped and fully labeled before it reaches an Amazon facility. Official notice. This guide is written for Amazon US sellers first, because the U.S. inbound network sets the baseline expectations for scan-ability and packaging integrity. But it is designed to remain useful if you sell globally and ship into EU/UK/CA/JP marketplaces—especially if you manufacture in China and route inventory cross-border before it reaches FBA. If you want a production workflow (barcode control, packaging QA, carton discipline, cross-border readiness), Get Started for Free. Contents Fast Answers: What Actually Causes Amazon Inbound Failures? Critical Update: Amazon Ending U.S. FBA Prep Services in 2026 How Amazon Receiving “Decides” If Inventory Is Acceptable Understanding FBA Prep Categories FBA Labeling Requirements (Unit, Carton, Pallet) FBA Packaging Guidelines (What Prevents Rejection) Compliance & Restricted Products (Hazmat, Expiration, Prohibited) International & Cross-Border FBA Prep Considerations Top FBA Prep Mistakes (Costs + Fixes) Tools & Workflows (Post-2026 Reality) Final Checklist Before Shipping to FBA People Also Ask: Short Answers Final Recommendation (U.S.-First, Global-Ready) FAST ANSWERS : WHAT ACTUALLY CAUSES AMAZON INBOUND FAILURES? What is FBA prep? FBA prep is the labeling, packaging, and compliance work required so each unit can be scanned correctly and handled safely inside Amazon fulfillment centers without rework. What is the #1 cause of receiving delays or rework? Barcode conflicts—more than one scannable barcode visible on a unit or carton, or labels placed where scanners can’t read them reliably. What changed in 2026 for Amazon US? Amazon states that starting January 1, 2026, it will no longer offer prep and item labeling services for FBA shipments in the U.S. store, so inventory must arrive fully prepped and labeled. Seller Central notice. What packaging mistakes cause immediate rejection risk? Packaging that opens, leaks, breaks, exposes product surfaces, or allows sets to separate during handling—especially liquids, fragile items, and sharp products. Does this apply to cross-border sellers shipping from China? Yes. Inbound requirements apply to inventory arriving at U.S. FBA, regardless of where it was manufactured. Cross-border sellers face extra failure points at customs and carrier handoffs before inventory reaches Amazon. CRITICAL UPDATE: AMAZON ENDING U.S. FBA PREP SERVICES IN 2026 Amazon’s official FBA Prep Service page includes this note: starting January 1, 2026, it will no longer offer prep and item labeling services for FBA shipments in the U.S. store. Official policy page. What this means operationally (U.S.-first, global impact): If you relied on Amazon for labeling, bagging, bubble wrap, or bundling, that safety net is gone for U.S. inbound. All units must arrive “scan-ready” and “damage-ready” before they reach an Amazon facility. Cross-border sellers must shift prep upstream: factory, origin warehouse, or a fulfillment partner. Reality Check: “We’ll fix it later” stops working in 2026 Common situation: A brand produces in China, ships into the U.S., and assumes Amazon will relabel or re-bag whatever is imperfect. Why it fails: After 2026, Amazon US prep/label services are discontinued. Inbound errors surface as delays, rework charges, or refused/blocked inventory. What to do now: Standardize a prep workflow with barcode control, packaging QA, carton/pallet discipline, and documented checks before shipment creation. HOW AMAZON RECEIVING “DECIDES” IF INVENTORY IS ACCEPTABLE The best way to think about FBA prep is not “Did we follow a checklist?” It is “Will Amazon’s system accept this inventory without intervention?” Amazon receiving outcomes are driven by two root causes: Identity failures (scan problems): barcode conflicts, unreadable labels, missing carton/pallet identifiers Integrity failures (handling problems): packaging opens/leaks/breaks, sets separate, sharp items puncture, liquids leak Ready rule of thumb: After prep, each unit should have one scannable identity and packaging that remains intact through warehouse handling. UNDERSTANDING FBA PREP CATEGORIES Amazon prep categories are less about product “type” and more about how products behave in storage and picking. If you classify based on marketing categories, you miss the real risk profile. Prep Category What Amazon Is Preventing Seller Decision Rule Loose products Units falling out of packaging, loose components Nothing opens or separates during handling Sold as set Set components split into separate inventory Physically bundle + “do not separate” marking Poly-bagged Contamination, leaks, exposed surfaces, warning non-compliance Secure seal + required warnings + barcode visibility Case-packed Receiving exceptions due to mixed quantities/SKUs Same SKU + same quantity per carton as shipment plan Special handling Damage, puncture, leakage, safety concerns Overprotect fragile/liquid/sharp products for warehouse touches Amazon’s packaging guidance is the baseline reference for packaging and bagging expectations. Product packaging requirements. FBA LABELING REQUIREMENTS (UNIT, CARTON, PALLET) Most expensive labeling mistake: Leaving multiple scannable barcodes visible after applying an FNSKU or other label. If a scanner reads the wrong code, receiving results become unpredictable. 1) Unit labeling: FNSKU vs manufacturer barcode Most U.S. sellers choose FNSKU to control unit identity. The practical goal is not “use FNSKU,” it is one scannable identity per unit. If any other barcode remains scannable, you have created a receiving failure condition. Place unit labels on flat, visible surfaces Do not wrap labels around curves or edges Fully cover or render other barcodes unscannable Run a quick scan test before cartons are sealed 2) Carton labeling: FBA Box ID labels Each box must have its own FBA Box ID label printed from the shipment workflow. Label placement matters: put it on a flat surface next to the carrier label so barcodes do not fold over edges. Shipping label requirements. 3) Pallet labeling: LTL / FTL shipments If

DDP by Default: EU Delivery That Prevents VAT-at-Door Practical IOSS/DDP Routing, Carrier Selection, and DDP vs DAP Decisions (2025) WinsBS Fulfillment – Maxwell Anderson Updated December 2025 TL;DR DDP (Delivered Duty Paid) means the seller pre-pays duties and VAT and executes customs clearance so the buyer receives the parcel with no payment request at the door. DAP (Delivered at Place) pushes VAT/duties and clearance actions to the buyer at arrival, which commonly causes customs holds, refusals, and RTS (return-to-sender). In 2025, with stricter EU VAT compliance under IOSS, tighter import scrutiny, and platform pressure from Shopify, TikTok Shop, and Amazon FBM, “DDP by default” is no longer a premium feature. It is the baseline execution standard for cross-border parcels. Brands switching from DAP-style shipping to DDP-style execution typically see: Higher checkout conversion because pricing becomes tax-inclusive and predictable Fewer refusals and RTS events caused by surprise VAT, duties, and brokerage fees More stable customs clearance outcomes and lead times Better delivery performance signals that support platform ranking and account health If you want to deploy a production-ready DDP workflow across EU/UK/US lanes (including IOSS and Section 321 routing), Get Started for Free.

They define who pays for freight, who handles customs, who pays duties and taxes, and where risk transfers from seller to buyer along the route. Traditional freight forwarders work with a longer list of Incoterms, but for cross-border eCommerce parcels, two terms do almost all of the work: DDP — Delivered Duty Paid DAP — Delivered at Place On paper, the difference between DDP and DAP looks like a small shift in who pays for duties and VAT. In practice, they create completely different customer journeys and P&L outcomes. For a Shopify, TikTok Shop, Amazon FBM, or crowdfunding brand, choosing the wrong term can be the difference between profitable scaling and constant firefighting. WHAT IS DDP (DELIVERED DUTY PAID)? Under DDP (Delivered Duty Paid), the seller takes responsibility for the entire cross-border parcel journey. That includes export procedures, international transport, import customs clearance, duties and VAT, and final-mile delivery to the buyer’s door. In a DDP setup, the seller or their logistics partner typically handles: Export clearance from the origin country (for example, China) Line-haul via air freight or express lanes Customs declaration in the destination country Payment of duties, VAT, and any import taxes Handover to last-mile carriers such as USPS, UPS, DHL, DPD, or Royal Mail The buyer receives a parcel that feels almost identical to a domestic purchase: the price shown at checkout is the price paid, with no extra door charges, no customs forms to fill, and no surprise visits from carriers asking for taxes. This is why DDP has become the default for modern cross-border eCommerce. It matches expectations shaped by Amazon Prime and other domestic delivery standards: transparent pricing, predictable timing, and minimal friction. WHAT IS DAP (DELIVERED AT PLACE)? DAP (Delivered at Place) is the mirror image of DDP when it comes to taxes and customs. Under DAP, the seller pays for transportation to the destination country or specified place, but the buyer is responsible for duties, VAT, and any clearance fees when the parcel arrives. In a DAP workflow, the buyer must often: Pay duties and VAT before release Pay carrier handling or brokerage fees Interact with customs or a postal operator Authorize the release of the parcel This may be acceptable for professional importers in a B2B context. For consumer parcels, it is a major break in the customer journey. Most retail buyers are not prepared to handle paperwork, unexpected charges, or customs deadlines. Many will refuse the parcel outright. As regulators, platforms, and buyers have evolved, DAP has shifted from “cost-saving shortcut” to “legacy freight term that does not fit eCommerce.” It still has a place in bulk B2B transactions but is a poor choice for direct-to-consumer shipping. DDP VS DAP: SIDE-BY-SIDE COMPARISON Putting both terms in a side-by-side matrix makes the trade-offs clearer: Aspect DDP (Delivered Duty Paid) DAP (Delivered at Place) Duties & VAT Paid by seller; taxes can be embedded at checkout Paid by buyer at arrival; often a surprise Customs Clearance Handled by seller or logistics partner Requires buyer action and payment Buyer Experience Like domestic delivery; no extra steps “Pay to get your package” experience Refusal Rate Typically under 5% when executed end-to-end Often 20–40% for retail parcels Delivery Speed Fewer holds and faster customs decisions Delays when buyers do not act quickly Total Cost Lower when returns, holds, and penalties are included Higher long-term due to operational friction Platform Performance Supports strong delivery scores and rankings Increases risk of penalties and demotion Best Use Case Cross-border B2C parcels High-value B2B freight with professional importers For cross-border parcels, this DDP vs DAP Incoterms comparison makes the conclusion straightforward: DDP aligns with how eCommerce actually works; DAP fights both buyer behavior and regulatory direction. DDP, DAP, AND DDU: COMPLETE DEFINITION CLUSTER Search engines and readers both benefit from a clear cluster of key term definitions. In the Incoterms space, three acronyms show up again and again: DDP (Delivered Duty Paid) means the seller assumes all responsibility for delivering the goods to the agreed destination, including paying duties, VAT,

Landed Cost Execution: Duty, Freight, Fees, and Fulfillment Costs A U.S. Import Framework That Shows When Costs Become Irreversible and What You Can Still Control By Maxwell Anderson · Updated 2025 DEC In U.S. import fulfillment, landed cost problems rarely start with a math mistake. They start when execution decisions are delayed until execution has already removed the option to redesign the path. Most cost overruns, missed delivery windows, and margin collapses are not caused by incomplete cost categories. They are caused by incomplete execution conditions: product definition gaps, responsibility gaps, and coordination gaps between nodes. Landed cost is not a static number. It is an execution path where adjustment room shrinks step by step as real actions happen. Cost control is the ability to make the right decision before each irreversible milestone. LANDED COST EXECUTION NODES (U.S. IMPORT FULFILLMENT) In the U.S. market, landed cost does not “appear” at the quote stage. It becomes locked in progressively as execution advances. This framework does not restate a logistics flowchart. It answers three operational questions at every node: Which costs are already irreversible at this node Which variables can still be corrected or redesigned How real constraints differ by product category at the same node EXECUTION NODE OVERVIEW (COST LOCK-IN VIEW) Node Core Action Costs Largely Locked Variables Still Adjustable Common Risk Pattern Node 0: Product Definition Define product, declaration name, category attributes None All Incorrect definition propagates downstream Node 1: Quote Confirmation Select execution path and responsibility boundaries Some freight assumptions Duty pathway, exception rules False certainty at the quote stage Node 2: Cargo Ready Freeze specifications and documentation Duty pathway Freight execution method Spec and compliance mismatch Node 3: Main Transport Sailing/flight execution, schedule reality Main transport cost Time-driven fees ETA drift converts into cost exposure Node 4: U.S. Customs Clearance Entry filing, inspection risk, release All duty Limited fee levers Inspection multiplies time and cost Node 5: 3PL Receiving Inbound warehouse execution starts Fulfillment structure Operational efficiency Warehouse deviations create additive fees Node 6: First Orders Shipped Order-level cost validation Full landed cost None Margin is realized too late to fix This table is an execution reference. It helps operators identify which node they are in right now, and which variables are still realistically controllable. NODE 0 — PRODUCT DEFINITION COMPLETED (PRE-QUOTE) Engineering definition: “Product definition completed” means the product is defined in a stable, auditable way that is usable for U.S. customs, transportation, warehouse receiving, WMS configuration, and order fulfillment. This is not marketing language. It is execution language. Key execution actions: Freeze three definitions: commercial product name, customs declaration name, and category attributes (battery, high value, oversized, regulated). Freeze the final selling configuration: single unit, bundle, kit, or multi-SKU set. Define the declared value logic and split rules (unit vs set, bundle components, replacements, inserts). Confirm whether the product contains regulated elements that affect routing (battery compliance, electronics labeling, restricted materials). Required outputs: A product definition sheet that can be used consistently for quoting and for customs entry. A specification sheet (dimensions, weight, materials, functional description, intended use). A category-attribute confirmation record (battery status, value band, oversize flag, compliance pathway assumptions). U.S. reality constraints: Product definition controls customs classification behavior and compliance gating. If definition is wrong here, later correction tends to trigger rework, holds, inspection exposure, or re-processing costs. The cheaper the correction seems at Node 0, the more expensive it becomes after Node 2. Category differences: Crowdfunding products often freeze definition later than typical DTC products, because reward structure and bundles finalize late. Battery-powered and electronic products do not have the same flexibility: the compliance pathway is effectively chosen here. High-value goods increase the consequence of every downstream mistake, including insurance, claims, and discrepancy handling. Oversized products magnify freight and warehouse handling exposure. Time-sensitive or seasonal SKUs convert every delay into revenue loss, not just expense. Node check: Can you produce a single definition that both your broker and your warehouse can use without rewriting it? Are product name, declaration name, and category attributes aligned? Is the selling configuration frozen, including bundles and inserts? NODE 1 — QUOTE & ROUTING CONFIRMATION (TRANSPORT + CUSTOMS) Engineering definition: This node does not determine “the price.” It determines the execution path, responsibility boundaries, and which assumptions will become the importer’s liability when reality changes. Key execution actions: Confirm trade terms and responsibility logic (who owns duty, who owns clearance outcomes, who owns exceptions). Confirm Importer of Record structure and who controls broker relationship. Break costs into auditable components: duty, freight, fees, and fulfillment charges, not a single bundled number. Document execution assumptions explicitly: port pair, routing, service level, timing window, free time assumptions, cargo parameters assumptions. Document exception triggers: re-routing, port change, inspection, holds, detention/demurrage, documentation repair, warehouse non-standard work. Define decision authority and spend authority for exceptions (who can approve, what thresholds trigger escalation). Required outputs: An itemized cost sheet that can be audited and compared later against invoices and warehouse charges. A responsibility matrix: who is responsible, who pays, who controls, and who bears exception cost. A written assumption and trigger file that removes “default handling” from the execution path. U.S. reality constraints: Assumptions that are not written become importer exposure. When execution deviates, added charges will be treated as “normal adjustments” unless the trigger and authority were defined upfront. Category differences: Crowdfunding needs a re-quote mechanism for bundle changes. Battery and regulated goods require the compliance pathway assumptions to be written, not implied. High-value goods require insurance responsibility and claims documentation standards to be defined at this node. Oversized goods require a re-rating trigger for dimension/weight changes. Time-sensitive goods require pre-authorization for mode switching or partial air uplift. Node check: Do you have an auditable split of duty, freight, fees, and fulfillment charges? Do you have a responsibility matrix that closes the “not my problem” gap? Are exceptions defined with decision authority, not just described as possibilities? NODE 2 — CARGO READY (SPEC + DOCUMENTATION FREEZE) Engineering definition: Cargo ready means assumptions meet

Best 3PLs for Shipping from China in 2025 Provider Landscapes Backed by the Vertical Fulfillment Performance Model (VFPM-2025) By Michael · Updated 2025 DEC On This Page Executive Summary VFPM Overview Shopify / DTC Amazon FBA Prep Crowdfunding Electronics / Battery Apparel & Fashion Beauty & Personal Care Heavy / Bulky Supplements / Food B2B / Omnichannel Section 321 / IOSS Final Recommendations Methodology EXECUTIVE SUMMARY The search for the “best 3PL in China” is misleading. WinsBS Research’s VFPM-2025 dataset shows that 25–48% of SLA variance and 30–55% of cost-per-order variance comes from vertical differences—not warehouse size, automation level, or geographic footprint. A 3PL that excels in fashion accuracy performs poorly in batteries; a 3PL optimized for crowdfunding waves fails under everyday Shopify volatility. This means that any universal ranking is inherently flawed. Instead, brands need a vertical-specific Provider Landscape. This report introduces 10 vertical landscapes—each with: a vertical profile grounded in VFPM-2025 cost, risk, and volatility models, a curated 6–12 provider evaluation pool (with external links), a Capabilities Matrix (SLA, SKU entropy, compliance readiness, volatility handling), a Why Included justification for every provider, and a vertical-specific RFP checklist. The goal is simple: give decision-makers an actionable, research-backed map of which 3PLs fit which products, channels, and compliance regimes when shipping directly from China. For brands planning China→US/EU expansions, WinsBS offers a free VFPM-aligned assessment: Get Started for Free. VFPM-2025 MODEL OVERVIEW The Vertical Fulfillment Performance Model (VFPM-2025) is WinsBS Research’s analytical framework for understanding why fulfillment performance differs dramatically across product categories—even inside the same warehouse. VFPM-2025 decomposes fulfillment into five structural components: Cost Structure — fixed vs. variable handling, packaging intensity, DIM exposure. SLA Stability — P50/P80/P95 transit distributions and last-mile variance. Labor Intensity — touchpoints, QC minutes, returns friction. Compliance & Risk — battery/DG rules, VAT/IOSS/321 requirements, regulator exposure. Volatility Handling — promo spikes, seasonality, crowdfunding waves. These metrics are normalized using VFPM’s trimmed mean and IQR median methodology to prevent outliers from dominating any vertical. The full methodology is documented in the VFPM-2025 Benchmark Report. This article applies VFPM-2025 to the specific context of shipping from China, where additional factors like customs clearance, long-haul reliability, and tax structuring materially change a 3PL’s suitability for each vertical. SEGMENT 1 — SHOPIFY / DTC BRANDS SHIPPING FROM CHINA Vertical Profile Shopify / DTC brands shipping 1,000–20,000 orders per month from China operate within a mid-volatility, mid-labor cost structure. VFPM-2025 shows that these brands experience predictable order waves around promotions, but relatively stable SKU entropy compared with apparel or beauty. What distinguishes this vertical is the emphasis on: carrier diversification for multi-region lanes, Shopify-native visibility for branded tracking events, tax orchestration (321 / IOSS / DDP) handled upstream, and the ability to maintain 6–12 day CN→US / CN→EU consistency. Provider Landscape (Evaluation Pool) The following 3PLs form the recommended evaluation pool for Shopify / DTC brands shipping directly from China.

Chinese New Year Shutdown 2026: Key Dates, Global Timelines & Supply Chain Risk How US, UK, EU, AU & CA Brands Should Plan Around Factory Closures and Logistics Capacity Drops By Maxwell Anderson · Updated 2025 Chinese New Year Shutdown 2026 — Key Dates You Must Plan Around Chinese New Year (CNY) in 2026 falls on February 17. For most manufacturers and logistics providers in mainland China, the disruption window is much wider than the public holiday itself. CNY 2026: February 17, 2026 Typical Final Production Window Before Shutdown: February 7–10, 2026 Initial Restart Window After CNY: February 24–26, 2026 (often only 20–40% capacity) More “Normal” Capacity: Early to mid March 2026 In practice, many factories wind down output in the 7–10 days before CNY, and only begin to ramp back up roughly 7+ days after the holiday. If you rely on China for production, your true planning window spans several weeks before and after February 17 — not just the holiday week itself. TL;DR FOR BUSY OPERATORS Chinese New Year shutdowns in 2026 will not only pause production in China for roughly two weeks — they will also squeeze logistics capacity before, during, and after the holiday. Most brands underestimate two things: how early freight capacity tightens, and how long it takes factory and logistics networks to return to something close to normal. If you sell into the US, UK, EU, Australia, or Canada, you should treat CNY as a multi-week disruption window, and build market-specific timelines for purchase orders, production, and shipping. This guide walks through what actually shuts down during CNY, how it impacts different markets, and how to build a destination-based, mode-based plan that protects Q1 revenue. WHY CNY 2026 MATTERS MORE THAN MOST BRANDS EXPECT Chinese New Year happens every year, but 2026 is not “just another holiday.” The timing and broader trading context make it especially sensitive for cross-border brands. First, CNY 2026 is later in the calendar than in 2025. That pushes the shutdown period deeper into February, closer to several demand events in key markets: Valentine’s Day, US tax refund season, and early spring launches for apparel, beauty, and consumer electronics. Second, the disruption is not limited to a single week of public holiday. Capacity starts to tighten weeks in advance as workers travel home, factory schedules freeze, carriers adjust sailings and flights, and trucking capacity thins out. Third, the recovery is slow. Even once factories officially reopen, labor does not return all at once, and logistics networks work through a backlog of cargo that built up before and during the holiday. The result is a practical disruption window that often spans four to six weeks. Brands that plan only around the public holiday dates typically find themselves short on inventory, stuck with delayed shipments, or paying much higher rates for last-minute air freight. WHAT ACTUALLY SHUTS DOWN DURING CNY 2026 (FACTORIES + LOGISTICS) Most discussions about Chinese New Year focus on “factory shutdowns.” In reality, what matters to your business is the combined effect of two different but overlapping slowdowns: production and logistics capacity. PRODUCTION: A GRADUAL STEP-DOWN, NOT A SINGLE CUT-OFF Factories in China rarely go from full speed to zero overnight. Instead, output tapers off over the two to three weeks leading into CNY, then ramps back up gradually over the following two to three weeks. Roughly three to four weeks before CNY, many factories begin to close their pre-holiday production schedule. New orders may still be accepted, but most will be booked for after the holiday. In the two weeks before CNY, certain workers — especially those who travel long distances — start leaving early. Some factories consolidate lines or reduce shifts. Output may drop meaningfully, even though the factory is technically operating. In the final three to five days before CNY, most assembly lines shut down. Remaining staff focus on wrapping up open orders and securing equipment. During the public holiday period, production stops almost entirely. After the holiday, workers return in waves. In the first week back, many factories operate at a fraction of normal output. It can take one to three weeks for staffing and quality processes to stabilize. Electronics and complex assemblies tend to slow down earlier and restart more cautiously. Apparel and soft goods may run closer to the holiday date and restart faster. LOGISTICS: THE REAL BOTTLENECK OF CNY DELAYS For many brands, logistics is the real problem. Even if a factory completes your order, you still need trucks, warehouse handling, and space in a container or on a flight. In the two to three weeks before CNY, exporters race to ship goods before shutdown, pushing trucking, warehouse operations, and terminal capacity into peak strain. During the CNY holiday week, logistics operates in a minimal mode. Some flights and sailings depart, but inland movement is extremely constrained due to driver shortages and terminal closures. After the holiday, a second congestion wave emerges as factories restart and release accumulated orders into the logistics network. This is why CNY-related delays often extend well into March. GLOBAL IMPACT: WHY DIFFERENT MARKETS REQUIRE DIFFERENT TIMELINES Even though the CNY date is fixed, its impact varies dramatically based on distance, customs, demand timing, and your fulfillment model. Two brands using the same supplier may need very different plans depending on: Transit time Customs clearance variability Market demand timing Local vs cross-border fulfillment Effective CNY planning begins with the market and works backward — not from the factory calendar alone. CNY 2026 REVERSE PLANNING TIMELINES BY DESTINATION MARKET To plan correctly, start with when you need inventory in each market, then subtract transit time, customs, and pre-CNY congestion. Destination Typical Ocean Transit Recommended PO Placement Recommended Ship-Out Window Safe Arrival Window Notes United States (West Coast) 30–35 days Early–Mid December 2025 Late Dec–Mid Jan Before Early Feb LA/LB congestion likely before CNY. United States (East Coast) 35–45 days Late Nov–Early Dec Mid Dec–Early Jan Before Late Jan Longer transit requires earlier planning. United Kingdom 35–50 days Late

How Amazon FBA Works (2025–2026) What Sellers Must Know About Prep, Inbound Routing & Storage Costs Author: Maxwell Anderson, Editor-in-Chief, WinsBS Research Last updated: 2025 Focus: Amazon FBA workflow, prep requirements, inbound routing rules, storage fees, and cost/risk control for cross-border e-commerce sellers shipping into the United States. TL;DR Amazon FBA in 2025–2026 is no longer just “send cartons to a warehouse.” It is a tightly enforced system covering prep rules (labeling, packaging, carton and pallet standards), inbound routing (SPD, LTL, FTL with routing plans and appointments), and storage fees (monthly storage plus Aged Inventory Surcharge, AIS ). Amazon is ending its own FBA Prep services by early 2026 , has increased placement and inbound defect fees , and now charges extra for inventory that sits too long. If you still treat FBA as “ship as much as possible and let Amazon figure it out,” your margin will erode quickly. The brands that win treat FBA as a disciplined flow : prep outside Amazon, route in smaller, compliant batches, and keep only 30–45 days of stock in FCs while using a U.S. 3PL buffer like WinsBS for bulk storage and kitting. That is how you protect Prime speed without letting storage and inbound costs quietly consume your profit. WHAT AMAZON FBA IS & HOW THE SYSTEM WORKS IN 2025–2026 Amazon FBA was designed to solve a simple problem for sellers: “If I send inventory to Amazon, they will store it and ship it for me.” In 2025–2026, that simple story is still true at a high level—but the details have become much stricter and more expensive. At its core, Fulfillment by Amazon (FBA) means: You create FBA shipments in Seller Central or via API. You prepare, label, and pack units, cartons, and pallets according to Amazon’s rules. You route inventory into one or more fulfillment centers (FCs) using small parcel delivery (SPD), LTL, or FTL. Amazon receives and stows your units, then ships customer orders and handles basic customer service and returns. In exchange, you pay: Fulfillment fees per order (pick, pack, outbound shipping to the customer). Monthly storage fees based on cubic feet and time of year. Aged Inventory Surcharge (AIS) when inventory sits beyond specific age tiers. Placement and inbound-related fees when Amazon redistributes units across FCs or shipments arrive with defects. For cross-border brands, FBA is both a growth engine and a risk amplifier . Prime eligibility and FBA Buy Box preference can lift conversion, but a single failure in prep, routing, or capacity planning can create: 7–15 day restock delays. Unexpected AIS and storage bills. Inbound defect charges and shipment rejections. Lost Best Seller Rank (BSR) and slower recovery after stockouts. To understand how Amazon FBA really works now, it helps to view it as a three-part system : Stage What Happens Key Risks Where Sellers Lose Margin 1. Prep Units are labeled, bagged, bundled, and cartonized according to FBA rules. Mislabeling, mixed-SKU cartons, fragile items under-protected. Rejections, rework, inbound defect fees, delayed check-in. 2. Inbound Routing Shipments are routed to FCs via SPD/LTL/FTL with routing plans and appointments. Wrong box size, weight or pallet standards, missed appointments. Extra carrier fees, detention at cross-dock, inbound defect penalties. 3. Storage & Flow Units are stowed; orders ship; aging inventory triggers AIS tiers. Overstocking, slow-moving ASINs, poor forecasting. High storage and AIS, restock limits, forced removals. If you manage these three stages deliberately, FBA behaves like a predictable engine. If you treat them as background details, FBA becomes an expensive black box sitting between your factory and your buyers. FBA PREP REQUIREMENTS (2025–2026 UPDATE) FBA prep used to be simpler. In 2025–2026, Amazon has tightened every rule around packaging, labeling, carton specs, pallet specs, and shipment accuracy —and Amazon is ending its internal FBA Prep services by early 2026 . That means: All prep must be done correctly before inventory reaches the FC. Amazon will not fix your issues. They will reject, charge, or delay the shipment. 1. Unit-Level Prep Requirements Every individual sellable unit must meet the following standards: FNSKU barcode must be scannable and not covered by other barcodes. Suffocation-warning polybags required for loose items or small textiles. Bubble wrap required for fragile units. Items with sharp edges must be securely protected . Expiration-dated goods must have MM-DD-YYYY printed and visible. Amazon grades prep accuracy heavily. Repeated issues increase your defect rate and lead to inbound defect fees . 2. Carton Requirements (2025 Update) Amazon increased its carton dimension limits in 2025: Maximum length: 36″ (up from 25″) Maximum side lengths: 25″ × 25″ Maximum carton weight: 50 lbs unless marked as “Team Lift” or “Mechanical Lift” Cartons violating these limits are frequently: Refused at the FC. Returned at your expense. Subject to inbound defect fees . 3. Pallet Requirements (2025–2026) Standard pallet size: 40″ × 48″ Maximum pallet height: 72″ including pallet Maximum pallet weight: 1,500 lbs Pallets must meet GMA Grade B+ or better Mixed-SKU pallets require proper labeling and must follow Amazon’s mixed-carton rules Non-compliant pallets face: Appointment cancellation Rejection at dock Re-delivery fees Delay penalties 4. Labeling Requirements All cartons and pallets require properly placed labels: FBA carton labels (2 per carton, opposing sides) Pallet labels (4 sides) SPD/LTL/FTL carrier labels Fragile indicators when necessary Improper placement or low print quality leads to scan failures and lost shipments. 5. Documentation Requirements Amazon increasingly checks: Carton content accuracy SKU-level quantities ASN matching Routing plan consistency Mismatches trigger manual review and receiving delays. HOW TO PREP YOUR INVENTORY FOR FBA — STEP BY STEP The workflow below represents what high-performing cross-border brands follow in 2025–2026. It reduces inbound defects, prevents rejections, and keeps replenishment cycles predictable. Step 1 — FNSKU Assignment & Packaging Decisions Before production finishes, confirm: Whether each SKU uses manufacturer barcode or FNSKU Required protective materials Whether variations need bundling Packaging thickness to survive U.S. carrier handling Step 2 — Factory-Level Labeling (If Possible) The cheapest and most accurate place to apply FNSKU is the factory. If the factory cannot

What Is a 3PL? The 2025 Guide to U.S. Fulfillment for Cross-Border Sellers Author: Maxwell Anderson, Editor-in-Chief, WinsBS Research Last updated: 2025 Focus: U.S. 3PL definition, fulfillment scope, pricing, compliance, and selection framework for cross-border brands shipping from Asia to the United States. TL;DR A 3PL in the United States is no longer “just a warehouse.” It has become the operating system that connects your factories in Asia, U.S. customs, Amazon FBA, and your own channels like Shopify and TikTok Shop. In 2025, cross-border brands rely on U.S. 3PLs to handle compliance (Section 321, UFLPA, HTS), multi-channel fulfillment (FBA, FBM, DTC), and carrier routing across UPS, USPS, FedEx, and Amazon Logistics. The 3PL you choose largely decides your margins, delivery promise, and growth ceiling for the next 12–24 months. Why 3PL Comes Before Everything Else in 2025 If you ship from China, Vietnam, or other Asian hubs into the U.S., the scenarios below will probably feel all too familiar. You open Amazon Seller Central and see a few key SKUs up 15–20% week over week, but your available FBM inventory in the U.S. is close to zero. Shopify shows a spike in orders after a TikTok campaign, yet your U.S. warehouse still has a container sitting in “receiving pending.” Your freight forwarder messages you that a recent Section 321 batch has been flagged by CBP for extra review. At the same time, your 3PL portal shows a 48-hour delay on check-in and a queue of FBA prep still waiting to be processed. Meanwhile, your channel mix keeps getting more complicated. FBA and FBM are running side by side, Shopify DTC is driving higher average order value, TikTok Shop rewards aggressive promotions but expects fast tracking uploads, and Walmart Marketplace is starting to matter more. All of those channels share the same U.S. inventory pool. Every slowdown inside the warehouse quickly turns into a stockout, a late shipment, or a performance alert on one of your dashboards. For U.S.-domestic brands, these issues are painful but not impossible to manage. They can visit the warehouse, hire local staff, switch carriers, or change 3PLs without crossing an ocean. For a cross-border brand sitting 8,000–12,000 kilometers away, none of that is realistic. You cannot walk into the building. You cannot stand behind the packing station. You cannot personally fix an API sync failure or repack a damaged pallet before it ships. That is why, for cross-border teams, how you define and choose a U.S. 3PL sets the ceiling for what you can do in the U.S. market. A 3PL is not just about racks and forklifts. It is the layer that: Connects the international leg (factory → port → ocean/air) to the domestic leg (customs clearance → drayage → last-mile delivery). Translates CBP rules, Section 321 strategy, and UFLPA exposure into concrete decisions on receiving and inventory placement. Turns orders from Amazon, Shopify, TikTok Shop, and Walmart into pick lists, cartons, tracking numbers, and SLA dashboards. Influences whether your U.S. customer gets a parcel in 2–5 days or ends up with a refund and a one-star review. If you want to grow in the United States without building your own warehouse and local team, your choice of U.S. 3PL is effectively a decision about your delivery standards, cost structure, and ability to scale over the next three years. This guide walks through what a 3PL actually is in U.S. practice, how it compares with FBA, FBM, and MCF, what its service scope and pricing look like in 2025, and how cross-border brands can evaluate U.S. fulfillment partners with a structured, repeatable framework. The Formal Definition of a 3PL The term 3PL gets used loosely in e-commerce and logistics, but its more precise meaning comes from a handful of industry references: the DHL Logistics Glossary, the Shopify Fulfillment Network documentation, and the annual Armstrong & Associates U.S. 3PL Market Study. Taken together, these sources describe a 3PL as a third-party organization that combines warehousing, order processing, carrier management, and inventory visibility into a single fulfillment system. A 3PL is neither the seller (first party) nor the carrier (second party). It sits between them as an independent provider responsible for moving both goods and data through the U.S. leg of the supply chain. In practice, a U.S. 3PL acts as both a logistics execution arm and a system layer for brands that need dependable U.S. fulfillment without owning a domestic warehouse. 1. A 3PL Is a “Third Party” in the Supply Chain A 3PL is not your in-house warehouse team, and it is not UPS, USPS, FedEx, or your freight forwarder. It is a separate business that bundles services such as: Receiving and putaway Storage and inventory control Pick, pack, and value-added processing Shipping using integrated carrier accounts Returns and reverse logistics Reporting, dashboards, and analytics In North American industry classification (NAICS), 3PLs are usually included under: • 493110 — Warehousing & Storage • 488510 — Freight Transportation Arrangement 2. A 3PL Is a Fulfillment System, Not Just a Building DHL and other references draw a clear line: subleasing pallet space is not the same as running a 3PL. A modern 3PL is a systematized fulfillment engine that handles inventory, orders, and shipping with defined workflows and measurable SLAs. A mature U.S. 3PL typically provides: Storage: pallet, bin, or cubic-foot based inventory management with transparent billing. Receiving: BOL/ASN matching, carton inspection, damage reporting, and timely check-in. Order fulfillment: single-unit orders, multi-line orders, kitting, bundling. Outbound operations: label generation, routing, staging, and carrier handoff. Reverse logistics: returns check-in, grading, restock or disposal as needed. Inventory visibility: real-time stock levels down to SKU and bin level. 3. A 3PL Runs on a Technology Backbone Modern definitions assume a certain level of technology. A U.S. 3PL without strong systems quickly turns into a bottleneck. At minimum, a 3PL should operate with: WMS (Warehouse Management System) for bin-level accuracy, lot/serial tracking, and real-time inventory updates. OMS (Order Management System) for multi-channel order aggregation, routing, consolidation, and exception handling. API/Webhook
