All Things Prep
FBA prep requirements after July 2026

Know the prep job before stock reaches Amazon

After the July 2026 change, sellers need cleaner SKU-level decisions before stock reaches FBA. ATP can help check labels, packaging, bundles, expiry handling and exception rules before inventory is sent.

OK

Label and packaging checks

OK

SKU-level handling rules

OK

Hold-before-action exceptions

Best fit for

  • Sellers unsure which SKUs need labels, bags, warning labels, bundles or special handling
  • Private-label and wholesale accounts where packaging errors are expensive
  • OA sellers with mixed retailer parcels and split deliveries

What ATP handles

  • FNSKU label requirement review before prep starts
  • Packaging checks for polybags, fragile goods, liquids, expiry dates and bundles
  • Damage, shortage and mismatch rules so unclear stock is held before action
  • Route into ATP pricing and first-batch testing before wider rerouting

Next step

Ask ATP for pricing, fit and next steps before you reroute live stock.

Prep is SKU-specific

A generic prep answer is weak. The right answer depends on the exact product, packaging, label and shipment route.

Unclear stock should pause

If a unit arrives damaged, short, wrong or under-documented, the safer move is evidence and seller approval before action.

References matter

Prep requirements work best when every parcel or carton can be tied to a seller, supplier order and expected SKU list.

Workflow

  1. Group SKUs by prep requirement, not just by supplier or shipment plan.
  2. Attach the correct reference and instruction before the parcel or carton is shipped.
  3. Let ATP check in the stock, flag unclear items and prep approved units.
  4. Review the first batch before scaling the route across more suppliers or retailers.

What to check before FBA receives the unit

RequirementSeller questionATP handling principle
FNSKU labelDoes this SKU need an Amazon label before FBA?Confirm label rule before printing or applying anything
Polybag or warningDoes Amazon require a bag, suffocation warning or sealed packaging?Keep packaging rule visible at SKU level
BundleWhich physical units make one sellable Amazon unit?Bundle only against clear instructions
Expiry dateDoes the date need to be visible or handled before shipment?Hold unclear expiry stock for seller approval
Damage or shortageWhat should happen if the inbound does not match expectation?Evidence first, then seller decision

Can ATP tell me Amazon's rules for every SKU?

ATP can help check the prep route, but sellers should still verify SKU-specific requirements inside Seller Central because Amazon rules can vary by product and account.

Should labels be decided before the stock is sent?

Yes. The label rule should be clear before the parcel or carton moves, otherwise the prep centre may have to hold and ask later.

What if I do not know the requirement yet?

Start with a small controlled batch and ask ATP to confirm the route before more stock is redirected.
