Amazon FBA Labeling Requirements 2026: Complete Guide for China Sourcing Importers
What Are Amazon FBA Labeling Requirements? Amazon FBA labeling requirements are the rules every seller must follow when sending inventory to Amazon fulfillment centers.
What Are Amazon FBA Labeling Requirements?
Amazon FBA labeling requirements are the rules every seller must follow when sending inventory to Amazon fulfillment centers. Every product unit needs an FNSKU barcode label, and some products require additional labels: "Made in China" labels, supplier barcodes, country of origin labels, and safety warning labels. Get any of these wrong and Amazon rejects your shipment — or worse, they accept it and you get hit with unplanned prep fees that eat your margin.
Why Labeling Mistakes Cost FBA Sellers Real Money
Amazon charges unplanned prep fees of $1.80-$2.40 per unit when your inventory arrives without proper labeling. For a 1,000-unit shipment, that's $1,800-$2,400 in avoidable fees. Sellers who import from China face extra risks: Chinese factories may not understand Amazon's labeling rules, or they use their own internal barcodes instead of Amazon's FNSKU. A third-party inspection that checks labels before the container leaves can save thousands.
7 Critical Label Checks for FBA Shipments from China
Step 1: FNSKU Barcode Label
Every single unit must have a scannable FNSKU label from your Amazon seller account. This is not the same as the UPC or EAN — Amazon generates a unique FNSKU for each product. The label must be permanent, not easily scratched or peeled, and placed on the outside of the product packaging where it can be scanned without opening the box.
Step 2: "Made in China" Label
US Customs requires every product imported into the United States to be marked with its country of origin. For FBA sellers, this means each unit — and often the outer shipping carton — needs a clear "Made in China" label. Products without this marking can be detained by US Customs, causing weeks of storage delays and fees.
Step 3: Supplier Barcode Removal or Cover
If your Chinese supplier puts their own barcode on the product packaging, it must be removed or covered with a black marker. Amazon scanners must see only the FNSKU. A visible supplier barcode can cause mis-scanning — Amazon might receive it as the wrong product in their system.
Step 4: Product Safety and Warning Labels
Children's products need CPSIA tracking labels. Electronics need FCC compliance marks. Toys need age warning labels. These are NOT optional — Amazon will remove listings that lack required safety labels, and you could face CPSC fines for non-compliant products.
Step 5: Expiration Date Labels
If your product has an expiration date (food, supplements, cosmetics), the date must be printed in the required Amazon format — year/month/day — and visible on the label. Amazon automatically removes inventory with unreadable or missing expiration dates.
Step 6: Shipping Box Labels
Each shipping carton needs a box content label showing the FNSKU, quantity, and destination FC. Amazon requires the carrier label (UPS/FedEx) on one side, the box content label on another. Don't tape over barcodes — they must remain scannable.
Step 7: Pallet Labels (FTL Shipments)
For full truckload shipments, each pallet requires four labels — one per side — showing the FBA fulfillment center address, pallet ID, and total carton count. Pallets must be stretch-wrapped with labels visible through the wrap.
How Pre-Shipment Inspection Helps with Label Compliance
A third-party inspection before your shipment leaves China can verify every label requirement before it's too late. Here's what an inspector checks:
| Label Type | Inspector Check | Rejection Risk If Missing |
|---|---|---|
| FNSKU barcode | Scannable, correct format, permanent | Shipment rejected at FC |
| Made in China | Present on each unit + carton | US Customs detention |
| Warning labels | Age, safety, CPSIA, FCC as applicable | ASIN delisted by Amazon |
| Supplier barcode | Removed or covered | Mis-scan at receiving |
| Box content label | Matches FNSKU + quantity | Returned by carrier |
| Expiration date | Amazon format, readable | Inventory auto-removed |
When Should You Do a Label Inspection?
The best time is after labeling but before container loading. This way, if labels are wrong, the factory can re-label units while they're still on the production floor. Book at 80% production complete. Label-only inspections start from $169/man-day and take 2-4 hours for most shipments.
Common Labeling Mistakes FBA Sellers Make
| Mistake | Cost | How to Avoid |
|---|---|---|
| Using UPC instead of FNSKU | Shipment rejected at FC | Print labels from Amazon Seller Central after listing is created |
| Supplier barcode visible | Units mis-routed in Amazon system | Instruct factory to cover or black out |
| "Made in China" too small | Customs fine ($500-2,000) | Use 8pt+ font size, clear contrast |
| Label on polybag not on product | Lost if bag tears | Label the product packaging itself |
| Wrong box content label quantity | Inventory discrepancy | Count and verify before sealing carton |
Frequently Asked Questions
Can the factory label my products for FBA?
Yes, many factories offer labeling services. But you must verify — give them a printed label template and a photo of the correctly labeled unit as reference. Even with instructions, factories often make mistakes. A pre-shipment label inspection catches these before shipment.
Does Amazon check labels at the fulfillment center?
Yes. Amazon uses automated scanners to read every FNSKU as it enters the FC. If a label doesn't scan, the unit goes to problem inventory — and you get charged unplanned prep fees starting at $1.80/unit.
Do I need "Made in China" on every unit inside a box?
US Customs says yes. Each individual product must be marked with country of origin. Even if the outer carton says "Made in China," the individual unit needs its own marking. This is one of the most common customs non-compliance issues for first-time importers.
How long does a label inspection take?
A label-only inspection for a standard 1,000-unit shipment takes 2-4 hours. The inspector checks 125-200 random units (AQL 2.5) for label compliance. You get a report with photos of each label type found on your products, and a pass/fail verdict within 24 hours.
What happens if labels fail inspection?
The factory gets the failure report with clear photos of each issue. You decide: re-label at the factory (5-10 cents per label), or ship as-is and risk Amazon fees. Most sellers choose re-labeling — it's cheaper than Amazon's unplanned prep fees.
