Amazon FBA (Fulfillment by Amazon) has made it easier than ever for sellers to reach customers worldwide. But it has also introduced a new set of requirements that go beyond basic product quality. Amazon has strict rules for how products must be packaged, labeled, and prepared for FBA fulfillment centers. Fail to meet these requirements, and your shipment may be refused, repackaged at your expense, or assessed penalty fees — on top of the damage to your seller metrics.
Why FBA Inspection Is Different
A standard quality inspection verifies that your product meets your quality standards. An FBA-focused inspection goes further — it also verifies that your products and packaging comply with Amazon's specific requirements for fulfillment center acceptance.
Amazon's FBA requirements cover:
- Product packaging and prep (polybagging, bubble wrapping, etc.)
- FNSKU barcode labeling and placement
- Suffocation warning labels on polybags
- Carton labeling and shipment ID labels
- Case-packed product requirements
- Expiration date labeling
- Product condition and "new" status
Many quality problems that would be minor in a traditional wholesale context become major issues in FBA. A wrong barcode, a missing suffocation label, or a slightly damaged retail box can all result in Amazon refusing inventory or charging you for unplanned prep services.
Key FBA Inspection Checkpoints
An FBA-focused quality inspection should include all the standard quality checks (workmanship, function, dimensions, packaging) plus these Amazon-specific verifications:
- FNSKU label verification: Confirm that each unit has the correct FNSKU barcode, that it is scannable, and that it is placed on the flat side of the package (not over seams or edges where it may be damaged). Each unit must have its own unique FNSKU — ASIN labels are not accepted for FBA.
- Polybagging requirements: Products that need polybagging (items that can dirty other inventory, loose items, certain apparel, etc.) must be in sealed polybags. Bags with a 5-inch opening or larger must have a suffocation warning printed on them or attached as a label.
- Suffocation warning: Must be clearly visible and legible. The specific wording varies by marketplace (US, EU, etc.) but generally must state that the bag is dangerous and should be kept away from babies and children.
- Expiration dates: Products with expiration dates must have the date clearly marked on the master carton and each individual unit. Amazon requires specific date formats and minimum remaining shelf life.
- Set/multi-pack verification: Products sold as sets must be clearly marked as sets and not easily separated. "Sold as set" labels may be required.
- Outer carton requirements: Cartons must meet weight and size limits, have proper labeling, and include shipment ID and carton number labels. Cartons must not have tape that obscures labels.
- Product condition: Retail packaging must be in "new" condition — no dents, tears, or damage that would cause Amazon to classify the item as used or warehouse-damaged.
Common FBA Pitfalls and How to Avoid Them
Amazon's FBA requirements are detailed and strictly enforced. Here are some of the most common mistakes Chinese importers make:
- Wrong barcode type: Some factories print EAN or UPC barcodes when FNSKU labels are required. Amazon cannot receive inventory without proper FNSKU labels. Always confirm which label type is needed and verify it during inspection.
- Barcode placement issues: Barcodes placed around corners, on curved surfaces, or over seams may not scan properly. Amazon requires barcodes on flat surfaces, away from edges.
- Missing suffocation warnings: Polybagged products without suffocation warnings will be refused or repackaged at the seller's expense. This is one of the most common FBA prep failures.
- Carton weight limits: Amazon has strict carton weight limits (typically 50 lbs / 22.5 kg for standard-size products in the US). Overweight cartons are rejected.
- Mixed SKUs in cartons: Unless using Amazon's partnered carrier with specific labeling, each carton should contain only one SKU for case-packed shipments.
Common Pitfall: Barcode Scannability
One of the most frequent FBA inspection findings is barcodes that look correct but do not scan reliably. This can be caused by low-resolution printing, incorrect barcode size, reflective packaging, or labels placed on textured surfaces.
A barcode that looks fine to the naked eye may fail to scan when Amazon's automated systems process your shipment. The result: your inventory is set aside for manual processing, you are charged unplanned prep fees, and your inventory availability is delayed.
Best practice: Always include actual barcode scanning in your FBA inspection checklist — not just visual verification. The inspector should use a barcode scanner (or at minimum a smartphone scanning app) to confirm that FNSKU labels are readable. For high-volume shipments, testing a sample of barcodes from different positions and production batches provides additional confidence.
FBA Prep Services vs. Self-Prep
You have two options for FBA prep: have the factory do it, or use a third-party prep service. Each has pros and cons.
Factory prep is usually the cheapest option, but quality can be inconsistent. Factory workers may not understand Amazon's specific requirements, and labels may be applied carelessly. If you go this route, a thorough FBA inspection at the factory is essential.
Third-party prep services specialize in FBA requirements and can handle labeling, polybagging, bundling, and more. They are more expensive but generally more reliable. Some inspection companies also offer FBA prep services, allowing you to combine inspection and prep in one visit.
For new products or new factories, we recommend starting with a third-party prep service until you are confident the factory can handle FBA requirements consistently.
Conclusion
Amazon FBA inspection is a specialized form of quality control that combines traditional product inspection with verification of Amazon's fulfillment requirements. Getting it right means your inventory arrives at Amazon's warehouses without delays, penalty fees, or rejected shipments. Getting it wrong can be expensive and damaging to your seller account.
If you sell on Amazon FBA and source from China, make sure your inspection partner understands FBA requirements and includes them in their checklist.
