FBA PREP SERVICE · CHINA FIRST-LEG
FBA prep from China: FNSKU, polybag, palletize — declared, executed, evidenced.
Since January 1, 2026, Amazon no longer preps US-bound FBA inventory on the seller’s behalf. WooliiPorter runs the prep at the China leg instead: your suppliers ship to your China warehouse address, declared prep services are executed with photo evidence, and the shipment departs for Amazon fulfillment centers in the US, EU, Canada or Mexico fully prepped.
PREP BY DECLARATIONnever added silently, closed with evidence
THE THREE PREP JOBS
What gets done before the first-leg departs
Polybag & protection
Loose or multi-part items are bagged per your declaration; polybags with large openings get suffocation warnings; fragile items get protective wrapping. Executed during packing from your instructions.
Palletize for LTL/FCL
Requested on FBA first-leg orders and performed at dispatch as part of the freight handoff, following the pallet and carton requirements of the booked shipment.
Exact label, bag and pallet specifications change; Amazon Seller Central is the authoritative reference and its current requirements prevail. Background on the 2026 policy change is in the FBA prep guide.
WHY DECLARATION-FIRST
Prep failures are instruction failures
Declared explicitly
Every prep service must be stated on the order. An FNSKU job without the label file and written instructions is not accepted — ambiguity is rejected at intake, not discovered at Amazon receiving.
Closed with evidence
Each declared service is executed from your instructions and closed with photo evidence before packing and quoting. What you approve is what was actually done.
Billed line by line
Each prep service is its own settlement line item, reconciling against the packed quote. No bundled prep fee whose contents you cannot inspect.
Same contract for agents
The identical declarations work over Merchant API V1 and MCP, so an AI agent placing an FBA first-leg order states the prep bundle in the same structured way.
NO STOCK COMMITMENT
Prep per shipment, storage only if you choose it.
Your supplier ships each batch to your WooliiPorter China warehouse address; it is received with scan and photo evidence, prepped per declaration, packed, measured and quoted from the live rate table. Stocking SKUs at the warehouse is a separate, optional decision — goods stay merchant-owned either way, and storage billing applies only to what you actually store.
How supplier parcel forwarding worksFIELD NOTES / FAQ
FBA prep questions
Yes, as an explicitly declared service. You upload the printable FNSKU label file and written instructions with the order; warehouse staff print, apply and photograph each labeled unit before the order can move to packing. Prep is never added silently — an order without the declaration and the label file is not accepted for that service.
