Amazon FBA Prep Requirements 2026: What’s New & How to Stay Compliant
If you’re selling on Amazon FBA and sourcing from China in 2026, one policy change has probably already cost you time, money, or both: Amazon has completely ended its in-house prep and labeling services for U.S. FBA inventory as of January 1, 2026.
No more polybagging at the warehouse. No more FNSKU label application. No more bubble wrapping, bundling, or kitting by Amazon. Whether your inventory arrives directly from your supplier, through Amazon Global Logistics (AGL), Amazon Warehousing & Distribution (AWD), SEND, or any other method, it must arrive fully prepped, labeled, and compliant—or it gets rejected, charged extra fees, or stranded. If you want the end-to-end process (shipping modes, routing options, timelines, and cost levers), start with our Complete 2026 China to Amazon FBA Shipping Guide.
For mid-size FBA sellers scaling $500k–$10M revenue, this means:
- Higher upstream costs if you weren’t already prepping in China.
- Increased rejection risk if your current forwarder or 3PL isn’t dialed in.
- More pressure on cash flow from delays or chargebacks.
The good news? Sellers who shift prep to reliable China-side partners (especially forwarders with integrated warehouses) are seeing rejection rates drop below 2%, saving 10–15% on overall landed costs through consolidation and accuracy.
This guide breaks down every 2026 prep requirement, what changed, how to comply upstream (especially for China-sourced goods), common pitfalls, and how Unicargo’s integrated prep + DDP shipping solves the problem end-to-end. Use the checklist, templates, and quote form below to stay compliant and protect your margins.
Key Insights – 2026 Amazon FBA Prep Essentials
- Amazon discontinued all U.S. FBA prep/labeling services Jan 1, 2026 – no exceptions, no partial help.
- All FNSKU labeling, polybagging, bundling, and protective packaging must happen upstream (China warehouse ideal for cost).
- Non-compliance = rejections, $0.50–$2+ per unit chargebacks, stranded inventory, or return-to-sender fees.
- Common categories (electronics, apparel, toys) have specific rules: suffocation warnings, fragile protection, and quiet zones on labels.
- Unicargo clients reduced rejections from ~12% to <2% by integrating prep at origin + quality checks.
- Upstream prep in China often saves 10–15% vs. U.S. 3PLs due to lower labor/material costs and shipment consolidation.

The Big 2026 Change: Amazon Ends All FBA Prep & Labeling Services (Jan 1 Onward)
What Amazon No Longer Does (FNSKU, Polybagging, Bubble Wrap, Bundling, etc.)
Effective January 1, 2026, Amazon stopped performing any prep or labeling in U.S. fulfillment centers. This includes:
- Applying FNSKU labels
- Polybagging loose items
- Adding suffocation warnings
- Bubble wrapping or protective packaging
- Bundling multi-item sets
- Kitting or set creation
- Any fragility/hazmat handling
Applies to All Flows (Direct, AGL, AWD, SEND, Supply Chain Portal)
The policy covers every inbound method—no carve-outs for Amazon’s own logistics services.
Why Amazon Made This Change & Impact on Sellers
Amazon cited operational efficiency and consistency. For sellers: more control over prep quality but higher responsibility and cost if not handled upstream properly.
Core Amazon FBA Prep & Labeling Requirements in 2026
FNSKU Labeling Rules (Placement, Scannability, Quiet Zones)
- FNSKU barcode must be scannable (minimum 80% contrast, quiet zone 1/8 inch).
- Place on flat surface, not on seams/edges.
- No manufacturer UPC substitution unless Brand Registry approved.
Polybagging & Suffocation Warnings
- Loose items (toys, apparel, small accessories) must be polybagged.
- Bags with openings >3 inches require a suffocation warning label in English (and other languages if needed).
Bundling, Kitting & Set Creation
- Items sold as sets must be securely taped/bundled.
- No loose parts; use tape, shrink wrap, or bands.
Fragile/Glass/Hazmat & Protective Packaging
- Glass/fragile items: bubble wrap + double-boxing if needed.
- Hazmat: proper MSDS, UN markings, outer carton labels.
Category-Specific Prep Matrix (Electronics, Apparel, Toys, etc.)
How to Prep Upstream for China-Sourced Inventory (Practical Steps)
Options: In-House, China 3PL, or Forwarder-Integrated (Unicargo Advantage)
- In-house: cheapest but error-prone for scale.
- China 3PL: good but adds coordination.
- Forwarder-integrated (Unicargo): best – prep + consolidation + DDP shipping in one partner.

Real Case Study: How Unicargo Clients Stay Compliant & Save
A mid-size electronics seller moved to Unicargo in Q3 2025 after dealing with a painful (and expensive) pattern: about 12% of inbound units were getting rejected at their U.S. 3PL because of inconsistent labeling and prep execution—things like scannability issues, missing/incorrect carton labels, mixed labeling standards across SKUs, and “fix it on arrival” rework that created delays at the exact moment inventory needed to be available for FBA. The change wasn’t just “using a different forwarder” – it was shifting the compliance work upstream. Unicargo integrated the seller’s FBA prep + labeling SOP directly inside the China warehouse, so cartons were prepped, labeled, and QC-checked before the containers ever left origin (with clear packing rules per SKU, carton-level checks, and a consistent handoff file for receiving). That one process change dropped rejections to under 2%, and on just the first 3 containers, the seller avoided $5K+ in combined fees and delay-related costs (re-label/rework, storage, appointment rescheduling, and time lost). More importantly, by reducing “surprise work” in the U.S. and tightening the origin-to-destination flow, they also saw a 10-15% lower total landed cost – not from magic rates, but from eliminating preventable friction: fewer touchpoints, fewer exceptions, and fewer last-minute fixes that quietly inflate cost per unit. The takeaway for Amazon FBA sellers is simple: the fastest way to cut rejects and protect margins is to treat prep + compliance as part of the supply chain design, not as an afterthought handled at the receiving dock.
