Amazon Killed FBA Prep: What Every Seller Needs Before Their Next Shipment
Amazon officially terminated all FBA prep and labeling services on January 1, 2026, forcing sellers to handle all poly-bagging, FNSKU labeling, and kitting before inventory reaches the fulfillment center. This shift creates massive operational risks, including shipment rejection, inventory disposal, and lost reimbursement rights for non-compliant goods. Sellers must now implement robust prep workflows or partner with a professional 3PL to maintain compliance. FBMFulfillment.com offers a seller-centric solution, providing expert prep, inventory possession control, and multi channel fulfillment support to navigate these changes and avoid costly Amazon storage fees and removal headaches.

This “temporary” measure is actually a permanent margin shave for ecommerce sellers, affecting FBA, Buy with Prime, and Multi-Channel Fulfillment (MCF) orders. To protect profitability, sellers must audit their SKU-level costs and diversify their logistics. FBMFulfillment.com offers a strategic alternative with predictable pricing, 2-day FedEx delivery, and total inventory control, allowing brands to maintain high service levels without the unpredictable overhead of Amazon’s growing fee list.
