Q: When are zippers eligible for return or replacement?
Returns and replacements are usually accepted when the zipper does not match the approved sample or the agreed specification, or when it fails in normal use within the stated period. Typical grounds are a wrong colour, a wrong length, a defective slider, a missing tooth, a broken puller or a packing count error. Damage caused after delivery, such as a bent slider from handling, a cut tape from a sewing needle or a heat mark from pressing, is normally not a supplier liability. Ask for the return authorisation before shipping anything back, and confirm the address and the freight responsibility. A common rule is that a confirmed defect is replaced or credited, and the defective pieces may be requested for analysis. Keep the return document linked to the original invoice and lot number. For a small value, a credit note is often simpler than a physical return, so ask which route the supplier prefers.
