Q: What evidence is needed to file a zipper claim?
A zipper claim is decided on evidence, so collect it early. Keep the carton label, the packing list, the invoice and the lot number, because they link the defective piece to a delivery. Photograph the defect close up and in context, with a scale and the garment or the carton visible. Record how many pieces were checked, how many failed and how the failure appeared: a missing tooth, a split chain, a stuck slider, a broken puller or a shade difference. State the test conditions, such as the number of cycles or the load applied, if a performance failure is claimed. Send the samples back if the supplier asks, and keep a duplicate. Report within the claim window stated in the order. A claim that names a quantity and a percentage is easier to settle than a general complaint. Ask the supplier to state the root cause and the corrective action, not only the credit amount.
