How to Use Pre-Shipment Inspections to Avoid Amazon FBA Rejection from China

Amazon FBA will reject a shipment for small mistakes. A missing warning label. A smudged FNSKU. Wrong carton dimensions. Those rejections cost time and money. Pre-shipment inspections (PSI) catch those problems before the container leaves China. Do the inspection right and you reduce the risk of FBA rejection to near zero.

What is a pre-shipment inspection?

A pre-shipment inspection is a final quality check done in China before goods are packed or loaded. An inspector tests samples, checks packaging, verifies labels, and inspects palletization. The goal is simple: confirm the shipment meets your purchase order and Amazon FBA rules.

When to schedule an inspection

Production Inspection: when about 30% complete to catch early issues.
During Production (DUPRO): at mid-production for process checks.
Pre-Shipment Inspection: when 80–100% of units are finished and packed but not yet sealed in the container. This is the one that prevents FBA rejections.

What inspectors check to avoid Amazon FBA rejection

Inspectors focus on items that Amazon enforces strictly. Here is a concrete checklist you can use:

FNSKU/barcode placement and scannability on each unit.
Amazon box label accuracy and placement on outer cartons.
Polybag size and suffocation warning, if used (polybags larger than 5″ x 5″).
Carton markings: ASIN, units per carton, net/gross weight, and country of origin.
Packing list and invoice match the shipment contents.
Product functionality for electronics and batteries. Check UN38.3 documentation for lithium batteries.
Safety labels and warnings required by Amazon and local law.
Expiration dates and lot codes for consumables.
Palletization: correct stacking, shrink-wrap, and no overhang.
Carton strength, internal protection, and item counts in each carton.

Sampling plan and acceptance criteria

Inspections use sampling. You rarely inspect every unit. Set clear acceptance levels to decide pass or fail. A common and practical approach:

Critical defects (safety, illegal, missing required labels): acceptance level = 0. Fail any critical defect.
Major defects (function, cosmetic issues affecting saleability): AQL 2.5.
Minor defects (small scratches, non-essential cosmetic marks): AQL 4.0.

For example, for a lot of 1,000 units, sample roughly 32–50 units depending on the standard. If you have many critical defects, the inspector fails the shipment regardless of sample pass rates. State these rules in the inspection order.

Types of inspections to consider

Full inspection — checks every unit. Use for high-risk or high-value items.
Spot check / random sampling — the usual PSI method.
Container loading check — verifies the container is loaded as claimed and seal intact.
Lab testing — for electronics, toys, cosmetics, and anything regulated.

How to work with inspection companies in China

Hire a reputable third-party inspector. Big names: SGS, Bureau Veritas, Intertek, QIMA. There are also many local agencies. Ask for:

Certificates and scope of work.
Photos of defects and packing during inspection.
A PDF report with measured values, counts, and pass/fail results.
Time-stamped photos of labels, barcodes, and cartons.

Expect a standard PSI to cost $100–$350 plus travel if the factory is remote. A container loading check is usually a bit cheaper. Plan 48–72 hours for scheduling in most Chinese cities. For remote provinces add travel time.

If the shipment fails inspection

Don’t panic. You have options:

Rework at the factory. Fix labels, repackage, repair defects.
Sort and remove defective units. Replace with compliant stock.
Reject the lot and negotiate with the supplier.
Request another inspection after corrective action.

Document everything. Use the inspector’s photos and report in supplier negotiations. Agree on timelines for re-inspection. Amazon’s clock doesn’t stop, but you can prevent the bigger problem of a rejected inbound shipment.

Special checks to prevent FBA-specific issues

Barcode verification: scan several units to confirm FNSKU and UPC read correctly.
Label placement rules: one label per sellable unit, no obstruction by hangtags or caps.
Bundled or multi-pack products: check that items aren’t loose and barcodes represent the pack.
Packaging dimensions and weight: match the declared data on your Amazon shipment plan.
Battery documentation: ensure test reports and UN shipment paperwork are ready.

Final tips to reduce rejection risk

Include a copy of Amazon packaging guidelines with the PO to the supplier.
Produce a clear inspection checklist and attach it to the PO and inspection order.
Insist on photos of every carton’s outer label before sealing the container.
Use a trusted inspection partner in the supplier’s region.
Schedule the PSI right before container sealing. That catches last-minute packing errors.

Wrap-up and next step

Pre-shipment inspections are a small cost compared to an Amazon FBA rejection. A short PSI prevents delays, chargebacks, and headaches. Use clear acceptance criteria. Pick a reliable inspector. Check barcodes, labels, palletization, and safety documents. Want help setting up inspections and managing suppliers in China?
