Why Amazon FCs Reject FBA Shipments — and How to Prevent Every One
A rejected delivery is the most expensive failure in FBA logistics because it happens at the end: production paid, freight paid, duties paid — and now storage on a truck full of stock nobody will take. The good news is that the causes are few, public, and almost entirely preventable upstream in China.

The direct answer
FCs reject or problem-flag shipments for a short list of reasons: unscannable or missing labels, cartons over published weight and size thresholds without the required handling marks, mixed-SKU cartons that violate the shipment plan, non-compliant pallet builds, missing prep the listing requires, and deliveries without a valid appointment. Every item on that list is verifiable at a China warehouse before loading — which is why rejection is a process failure, not bad luck.
The failure map: from FC gate back to the factory
| Failure | Why It Happens | Where It Should Have Been Caught |
|---|---|---|
| Unscannable FNSKU or carton ID | Light thermal print, labels over seams or curves, inkjet under tape, ghost barcodes under labels. | 100% scan gate at China pack-out. |
| Overweight or oversize cartons | Dense goods packed to carton capacity; thresholds checked by eye instead of scale. | Scale check per carton at pack-out; labels applied automatically above thresholds. |
| Mixed-SKU cartons vs. plan | Factory habit of topping off cartons; plan built on case-logic that never reached the line. | Carton manifest verified against shipment plan before loading. |
| Pallet build defects | Overhang, non-uniform decks, loose wrap, wrong pallet format for the destination country. | Pallet spec in the work order; photo record of each finished pallet. |
| Missing prep | Requirements taken from memory or last season's rules instead of the current ASIN page. | Prep requirements pulled from Seller Central per shipment, written into the PO. |
| No or wrong appointment | Appointment treated as a post-arrival task; or plan revised after booking. | Slot booked at vessel load; re-verified on any plan revision. |
| Compliance gaps (expiry, marks, language) | Product manufactured without a destination-market requirement that was never in the spec. | Destination-market checklist before the purchase order, not before the sailing. |
The China-side prevention checklist
Rejections are decided weeks before the truck rolls. This is the sequence a China prep hub should run — and the one we run — on every outbound FBA consignment:
Pull the current rules. Prep requirements and thresholds re-checked in Seller Central for each ASIN in the shipment — rules move, memory does not.
Spec the PO, not the phone call. Every prep step, label rule and carton threshold written into the purchase order the factory signs.
Weigh and measure, do not estimate. Scale and tape on every carton; heavy and oversize handling labels applied at pack-out, not discovered at the gate.
Scan everything. Every FNSKU and every carton ID scanned at the hub; failures reprinted on the spot. The scanner is the cheapest quality inspector you will ever hire.
Verify the plan is alive. Labels printed only from the active shipment plan; any plan revision triggers a label audit before loading.
Photograph the truth. Cartons, marks, pallets and load-out photographed per shipment — the evidence that settles any dispute in minutes.
If it still goes wrong: the rescue sequence
When a delivery is refused, the clock starts on three costs at once: the truck or container's time, storage wherever the freight lands, and re-delivery. The sequence that minimizes all three:
- Land the freight somewhere planned. A partner warehouse near the FC network beats a random truck yard — this is what our transload and re-injection workflow exists for.
- Diagnose against the refusal reason. Photographs from the China load-out determine whether the claim is real and what exactly needs rework.
- Re-prep against a corrected plan. Relabel, re-carton, re-pallet — and rebuild the shipment plan if the FC assignment changed.
- Re-book the appointment, then re-deliver. Slot first, truck second; the reverse order is how the same freight gets refused twice.
Rejection FAQ
What is the difference between a rejection and a problem transfer?
A rejection happens at the gate: the delivery is refused or partially refused before unloading, and the truck leaves with your freight. A problem transfer accepts your freight but flags units or cartons for issues — wrong labels, missing prep, damaged units — then bills handling work and routes stock to problem resolution. Both are failures; only one leaves you with options.
Who pays when a delivery is rejected?
Contractually, whoever failed their link: usually the shipper's labeling or prep process, and practically the seller, via storage, re-delivery and re-prep costs. The forwarder carries freight and appointment logistics; the seller owns the compliance of what was loaded. This is why the prevention checklist lives on the China side, where the work is cheap.
Are overweight boxes really rejected, or just fined?
Both outcomes occur depending on marketplace, FC and severity. Cartons over published thresholds without the required handling labels risk refusal at receiving or problem classification after receipt. It is not a fine you can budget for and forget — treat every threshold as a hard gate in the pack-out checklist.
Can a rejected shipment just be re-delivered?
Only after the cause is physically fixed: relabeled, re-prepped, re-cartoned, re-palletized — and re-appointed. The goods need somewhere to land while that happens, which is the operational case behind our transload service: a warehouse near the FC network where a corrected plan can be built, executed and re-slotted.
