Amazon FBA Prep Ended in 2026: What Sellers Do Now

Amazon ended its in-house FBA prep and labeling services for US sellers on January 1, 2026, discontinuing poly-bagging, bubble wrapping, bundling, kitting, and FNSKU labeling that Amazon previously performed for a fee. Every FBA shipment must now arrive fully prepped and compliant before it reaches a fulfillment center — sellers prep it themselves or hand it to a third-party prep center or 3PL.

If you've been shipping to Amazon for a while, you've probably leaned on Amazon's own prep service more than you realized — a label applied here, a poly bag there, a case pack fixed up before it hit the dock. That safety net is gone. What used to be Amazon's problem to fix on your behalf is now entirely yours to get right before the box ever leaves your building.

What did Amazon actually stop doing for FBA sellers?

Amazon's FBA prep service used to let sellers send in loosely prepped inventory — cases not yet broken down, units missing FNSKU labels, multi-packs not yet bundled — and pay Amazon a per-item fee to finish the job on receipt. As of January 1, 2026, that option is gone for US shipments. The discontinued tasks include:

• FNSKU labeling — applying Amazon's scannable barcode to each unit
• Poly-bagging — sealing loose or multi-unit items per Amazon's packaging rules
• Bubble wrapping — protecting fragile items in transit
• Bundling — combining units into a single sellable multi-pack ASIN
• Kitting — assembling components into a finished sellable unit

Amazon's stated reasoning, per Supply Chain Dive's reporting, is that a mature network of third-party prep providers now exists, so Amazon is stepping back to focus its own warehouses on moving inventory rather than prepping it. Shipments created before January 1, 2026 got a short grace period even if they arrived after the cutoff — but that window has closed, and every new inbound shipment is on the new rules.

Why is my FBA shipment getting rejected now?

Rejections and defect fees happen because compliance responsibility moved from Amazon to the seller with nothing else changing about Amazon's underlying packaging and labeling rules. The rules for how a unit has to be labeled, bagged, and packed didn't get easier — Amazon just stopped being the one who'd quietly fix it for you.

A shipment that arrives without a scannable FNSKU, without required poly-bagging, or with cases packed outside Amazon's spec can now be turned away, held for correction, or hit with inbound defect fees on the non-compliant units. Those fees are set and updated by Amazon, not by us — check the official fee schedule for current rates before you ship, since third-party trackers report the numbers moving several times already in 2026. The practical risk is the same regardless of the exact rate: a rejected or held shipment means inventory that isn't sellable during whatever selling window you built that shipment around.

Who preps FBA inventory now that Amazon doesn't?

Sellers now have two real options: build prep in-house, or route inventory through a third-party prep center or 3PL before it ships to Amazon. In-house means finding space, training staff on Amazon's spec, and stocking poly bags, labels, and packing materials — workable for very high-volume single-SKU sellers, but a real operational lift for most brands.

For everyone else, a prep center or 3PL that already runs FBA prep day in and day out is usually faster to stand up and cheaper than building the capability from scratch, because the space, training, and supply chain for poly bags and labels already exist. Honeybee Fulfillment, the Shopify-focused 3PL in Plano, TX ($2/order flat, 99.9% accuracy), offers Amazon FBA prep as a service alongside its core Shopify DTC fulfillment — receiving inventory, prepping it to Amazon's current spec, and shipping it on compliant. See the Amazon FBA prep page for what's included.

Can one partner handle both my Amazon FBA prep and my Shopify orders?

Yes — and for a brand selling on both channels, that's the more efficient setup than running two separate vendors. One warehouse receiving all of your inventory can split it between FBA-bound stock and DTC-bound stock, shifting the split as your Amazon velocity or Shopify demand changes, instead of you managing a prep center for Amazon and a totally separate 3PL for Shopify fulfillment.

That matters more this year specifically: with Amazon's prep service gone, the "just let Amazon handle it" option that many multi-channel sellers relied on for their FBA side no longer exists, which makes consolidating FBA prep and DTC fulfillment under one roof a meaningfully bigger time save than it was in 2025.

What should Shopify + Amazon sellers do this quarter?

Don't wait for a rejected shipment to force the decision. Audit your next few inbound FBA shipments against Amazon's current labeling and packaging spec, and decide now whether you're building prep in-house or handing it to a partner — doing that decision under deadline pressure after a shipment gets bounced is the expensive way to learn the new rules.

If you're already rethinking your fulfillment setup, it's worth zooming out past just FBA prep: brands weighing whether to move DTC fulfillment to a 3PL entirely are often the same brands who benefit most from consolidating Amazon and Shopify inventory in one warehouse. Either way, the sellers who adjust their process now — instead of after a held shipment costs them a selling week — are the ones who come out of this change ahead.
