China Sourcing for Amazon Sellers
A China sourcing guide for Amazon sellers: spec lock, packaging, inspection, FBA prep, and a ship date that matches your inbound plan.
Built for: Amazon FBA and FBM sellers
An Amazon order has two specifications. The first describes the product the customer buys. The second describes the unit, carton, and shipment data Amazon expects to receive. Both need to be settled before cargo leaves China.
Fulfillment by Amazon (FBA) means Amazon receives the cartons. Fulfillment by merchant (FBM) means you ship the customer order. Most of the checklist below is the FBA handoff. The barcode decision still sits in your account for either model: your Brand Registry role and the product’s eligibility choose the symbol, and the agent applies that file.
Build the buying file from the listing
Write down the product specification, target quantity, destination marketplace, required date, and current supplier information. Include the sellable-unit definition and any packaging or labeling requirement that affects production. A listing image can guide the discussion, but it cannot replace measurements, material, accessories, and an approved sample.
If the factory has not been selected, the product sourcing guide explains how to build a comparable shortlist. If a supplier is already quoting, the supplier verification guide helps check the company before a deposit.
Keep the first order controlled
A smaller trial may be possible when the supplier accepts it. The trial still needs a written specification, sample approval, production follow-up, and inspection. Small quantities do not make a wrong barcode, weak package, or missing accessory less serious.
Create the FBA shipment after the ready quantity and carton plan are stable. The prep team needs the label files from the current workflow, not a saved file from an older shipment. The Amazon FBA prep guide lists the unit and carton checks to ask a prep provider in China for.
FBA seller checklist for a China sourcing agent
When you choose a China sourcing agent for Amazon, ask how it will prove that the goods match your shipment before they leave China. Product sourcing is only part of the job. The agent also needs to apply the right barcode, label each carton, match the box contents, and hold a failed lot. The questions below test that. Each answer should come with evidence, not only a yes.
Amazon’s rules are set in Seller Central and they change. The points below were checked against Amazon’s shipping label requirements and FBA barcode requirements on October 6, 2026. Confirm the live pages and your own shipment workflow before every booking.

| Check | Ask the agent | Evidence to request before release |
|---|---|---|
| Unit barcode | Who decides whether each SKU uses the manufacturer barcode or an Amazon barcode (FNSKU)? | Your barcode setting per SKU, plus a scan of one finished unit from each SKU |
| SKU mapping | Where does the prep team get the FNSKU for each variation? | Label files from your current shipment, not from an earlier one |
| Box ID labels | Will every carton get its own box ID label from the shipment workflow? | A label register that pairs each label with a carton number |
| Label placement | Where do the box ID and carrier labels go? | Carton photos showing both labels on a flat face, not across a seam |
| Box contents | Who checks the SKU and unit count in each carton against your box content information? | A packing list reconciled to the shipment record |
| Carton data | Are weights and dimensions taken from sealed cartons? | Measured weight and size per carton |
| Inspection | Is the lot inspected against the approved sample before the balance and the booking? | An inspection report with defects and measurements |
| Failed lot | Who can stop the cargo, and who pays for rework and re-inspection? | A written answer in the quote |
Amazon’s official announcement applies the change to inventory shipped on or after March 31, 2026. A brand owner must hold the Brand Representative selling role in Amazon Brand Registry to use manufacturer barcodes under that policy. Resellers without that role must apply Amazon barcodes even when a manufacturer barcode is present. Products without a manufacturer barcode require Amazon barcodes for either seller type; check product eligibility in Seller Central. The barcode choice belongs to you and your Seller Central account. The agent applies your instruction and should not decide it by looking at a listing photo.
Amazon also states that each box needs its own FBA box ID label, and that labels must not be photocopied, reused, or modified for other boxes. If an agent plans to print one label and copy it for a whole carton run, it is not ready for an FBA file.
A small first order is a practical way to test these answers. Use one SKU, ask for the label register and carton photos, and see how the agent reports an ordinary mismatch.
Plan freight around stock and receiving
Compare air, sea, courier, or a split shipment using the final carton measurements. A stockout risk may justify sending part of the order faster while the balance follows by sea. Keep Amazon check-in and receiving separate from carrier delivery when planning availability.
The China to Amazon FBA guide gives the full release checklist. Once the cartons and destination allocation are final, ask forwarders to quote the physical shipment rather than an estimate; the shipping from China guide shows how to compare those quotes.
Common problems to check for
- Listings change after the factory already cut material
- FBA prep is left for the US 3PL
- A failed lot still sails because nobody held the cargo
Frequently asked questions
Can a first FBA order be small?
Yes, if the supplier accepts it. A small first order still needs a written specification, sample approval, unit and carton labels from the current shipment, and an inspection before release.
Who decides between a manufacturer barcode and an Amazon barcode?
You do, in Seller Central, based on your Brand Registry role and the product's eligibility. An agent or prep provider should apply your instruction, not choose the barcode from a listing photo.
What does the Brand Representative role change?
Amazon's March 31, 2026 announcement, as checked on 6 October 2026, lets a brand owner with the Brand Representative role use a manufacturer barcode on eligible products. Resellers without that role apply Amazon barcodes even when a manufacturer barcode is already on the unit. Confirm the live help page before you book.
Does a heavy carton skip the box ID?
No. Each carton still needs its own box ID from the current shipment. A team-lift or heavy-package mark, if your workflow asks for one, is extra. This page does not restate a weight cutoff. Read the live shipment workflow for that rule.
