Amazon's prep requirements are unforgiving — a missing label or wrong poly-bag can get a shipment refused or surcharged. Most of it is avoidable with a checklist and a prep team that does this daily.
Before anything ships
- FNSKU labels on every unit, covering the original barcode
- Poly-bagging with suffocation warnings on larger bags
- Sets and bundles marked “sold as set”
- Legible expiration dates on consumables
Case-pack and box rules
Amazon caps box weight and flags oversized cartons. Mixed-SKU boxes need accurate content info and master cases must match declared quantities, or you'll spend weeks on reconciliation.
Why prep belongs where inventory lives
When prep happens in the same Commerce, CA building that stores your stock, there's no extra freight leg. Inventory arrives, gets prepped to spec, and ships to Amazon — or your own customers — from one place.
