Document first — and do not send anything back. A wrong-product claim is won or lost in the first hour at your warehouse: the photographs, the packing list and a written notice to the factory decide the outcome, not the argument that comes afterwards.
First: document, before you touch anything
Photograph the shipment exactly as it arrived. Shoot the closed cartons with their shipping marks, then the packing list, then the contents as each carton opens. Keep all packaging. Count what you actually received against the packing list and your purchase order line items. This record, made before anything is moved or used, is what the entire claim rests on.
Work out which kind of wrong this is
Wrong item, wrong variant, wrong quantity and mislabeled cartons are four different problems. A completely different product usually points to a packing or dispatch error; the right product in the wrong colour, size or finish points to production working from the wrong spec. Compare the goods against your approved sample and the documents you fixed before ordering — the diagnosis changes who fixes it, and how fast.
Put the claim in writing, with the evidence attached
Email the factory the same day, referencing your PO line numbers. Attach the photographs and state plainly what was ordered and what arrived. Ask the factory to trace the error on its side — a packing mistake shows up quickly in warehouse records. If the goods themselves are defective rather than simply wrong, the conversation follows the quality-dispute route instead.
What to avoid: shipping it back
Do not return goods to China before a written agreement on who pays and what happens next. Return freight plus import clearance back into China frequently costs more than the goods are worth, which is why most wrong-product cases settle with a replacement in the next shipment, a credit note, or local disposal of the wrong stock. A verbal “send it back and we’ll sort it out” is not an agreement.
Know where your leverage sits
An unpaid balance is your strongest position; use it calmly. Under a standard 30/70 arrangement, agree the remedy in writing before the balance moves. If everything is already paid, your leverage is the evidence file and the next order — set a written deadline for the factory’s proposal rather than an open-ended promise.
Prevention: catch it while it is still in China
A pre-shipment inspection checks the actual goods and the carton markings before loading, which is where a wrong-product error costs the least to put right — see how pre-shipment inspection works. Writing the labeling and carton-marking requirements into the purchase order itself gives the inspector, and the factory’s packers, one unambiguous reference.
