Amazon FBA Prep Checklist: 7 Common Rejection Reasons to Avoid

Missing or incorrect FNSKU labels - every unit needs Amazon's own barcode covering (or alongside, depending on category) the manufacturer barcode, correctly linked to your listing.

Poly bagging without suffocation warnings - any poly bag with a 5-inch or larger opening needs a printed suffocation warning per Amazon policy, or the shipment gets flagged.

Incorrect carton weight or dimensions on the shipping plan - cartons that don't match what you declared during shipment creation cause receiving discrepancies and delays.

Missing or wrong "Made In" country labeling - required on the product or packaging for most categories, and checked during receiving.

Bundled items not properly identified - if you're selling a multi-pack or bundle, it needs its own bundle-specific barcode, not just the barcodes of the individual components.

Fragile items without adequate protective packaging - Amazon's fulfillment centers handle inventory roughly; anything that arrives damaged due to inadequate packaging can result in reimbursement disputes, not just rejected units.

Incorrect unit count per carton vs. the shipping plan - miscounts trigger a manual recount at the warehouse, which delays your shipment's availability for sale.

Every one of these is avoidable with correct prep before the shipment ships from China - which is the entire point of doing FBA prep at the source instead of discovering these problems after a rejected shipment sits in limbo.
