A source-backed reference to the major US FBA prep, item-labeling and barcode changes that took effect in 2026. This page focuses on dates, scope, exceptions and Amazon primary sources; the separate seller operations guide covers where prep should happen and how to choose between a factory, prep center and 3PL.

Amazon stopped offering its own FBA prep and item-labeling services — it did not end FBA.
Amazon states that, effective January 1, 2026, it no longer offers prep and item-labeling services for newly created US-store FBA shipments. Sellers must arrange the required preparation and labeling before inventory is sent into FBA. A separate barcode-rule change took effect on March 31, 2026 and affects how resellers and eligible brand owners use Amazon or manufacturer barcodes.
The 2026 policy timeline
Amazon also describes transition treatment for shipments created before January 1, 2026: those shipments can still receive the former prep or labeling service even when the inventory arrives after the effective date.
Which FBA inbound paths are covered?
Amazon’s FBA Prep Service notice applies to US-store FBA inventory and also addresses inventory entering FBA through programs such as Amazon Warehousing and Distribution, Amazon Global Logistics, Amazon SEND and Supply Chain Portal. The practical rule is the same: the required prep and labeling need to be completed before the inventory reaches the FBA receiving stage for shipments created after the cutoff.
What Amazon did not end
| Still available | What the policy means |
|---|---|
| Fulfillment by Amazon | FBA continues to receive and fulfill inventory that meets the applicable requirements. |
| Seller or manufacturer prep | Sellers can perform the work upstream or instruct another party to do it. |
| Third-party service providers | Amazon’s guidance recognizes outside service providers as an alternative to the former Amazon prep service. |
| SIPP | Eligible certified products can use Ships in Product Packaging under its own eligibility and testing rules. |
The separate March 31, 2026 barcode change
Prep and barcode policy are related but they are not the same rule. Amazon’s current US barcode guidance says that from March 31, 2026, resellers are required to use Amazon barcodes even when a manufacturer barcode exists. Eligible brand owners can continue using manufacturer barcodes when the product and account are eligible.
Avoid turning this into a universal shortcut such as “every unit needs an FNSKU” or “the UPC is always enough.” The seller’s role, ASIN eligibility and the live Send to Amazon workflow control the actual barcode path.
What responsibility moved upstream?
The policy change shifts responsibility for getting inventory into a shipment-ready state away from Amazon’s former optional prep service and into the seller’s upstream process. That work can be performed by the seller, manufacturer or a third-party provider, but the seller still needs to make sure the current SKU-level instructions are correct.
| Responsibility | What should be controlled |
|---|---|
| Prep specification | Packaging, set or bundle treatment, warnings, fragile protection and product-specific requirements. |
| Barcode choice | The approved barcode path for the seller and ASIN before labels are printed. |
| Verification | Scannability, label placement, quantity and packaging before inventory is released. |
| Shipment data | Current box, pallet and routing information from the live Amazon workflow. |
Why the reimbursement language matters
Amazon’s FBA Prep Service notice warns that products with missing or improper prep may be damaged and products with missing or defective labels may become untraceable. For shipments created after January 1, 2026, the notice also describes reimbursement consequences for affected inventory. That makes prep verification a compliance and traceability control, not simply a warehouse convenience.
Where SIPP fits
Ships in Product Packaging is a separate packaging program. Amazon says eligible certified products can ship in their own product packaging without added Amazon packaging and may receive applicable fulfillment-fee discounts. SIPP does not remove other barcode, safety, eligibility or shipment requirements, so it should not be treated as a universal substitute for prep.
What sellers should verify before acting on a generic checklist
- the current Seller Central instruction for the actual ASIN and shipment;
- whether the seller is acting as a reseller or an eligible brand owner for barcode purposes;
- whether product-specific prep, warnings or packaging rules apply;
- whether SIPP is relevant and the product is eligible;
- the current shipment plan before final box or pallet labels are applied.
Amazon account instructions can change by product and workflow. A published guide is useful for understanding the policy, but the live Seller Central instruction remains controlling for the actual shipment.
Factory, China prep warehouse, US prep center or full-service 3PL?
The separate operations guide compares those four models by control, rework risk, receiving needs and total handling cost.
Frequently asked policy questions
Did Amazon end FBA in 2026?
No. Amazon ended its own prep and item-labeling services for US-store FBA shipments beginning January 1, 2026. FBA itself continues to receive inventory that is correctly prepared and labeled.
What changed on January 1, 2026?
For newly created US-store FBA shipments, Amazon no longer performs its former prep and item-labeling services. Sellers need to arrange the required work before inventory is sent into FBA.
What changed on March 31, 2026?
Amazon’s US barcode guidance says resellers are required to use Amazon barcodes even when a manufacturer barcode exists, while eligible brand owners can continue using manufacturer barcodes. The live workflow and product eligibility remain controlling for each SKU.
Do sellers have to use a third-party prep center?
No. Amazon says sellers can prep products themselves or use a service provider. A manufacturer or other upstream partner can also perform the work when the seller supplies the correct requirements and verifies the result.
Can SIPP replace prep requirements?
Not generally. SIPP can reduce added packaging for eligible certified products, but it does not remove product-specific barcode, safety, packaging or shipment requirements.
