As of January 2026, Amazon no longer preps FBA inventory at its fulfillment centers. Here is what FBA prep is, what changed, and how to pick a prep center that keeps your inventory moving.
Amazon FBA packaging requirements by product type: poly bag rules and suffocation labels, fragile and oversize prep, box size and weight limits, and case-pack specs, organized by category so you can check your products fast.
What FBA prep actually costs by service type: labeling, poly bagging, bubble wrap, bundling, and oversize prep, plus how standalone prep-center fees compare to a 3PL that preps and ships from one inbound.
