Q: How is CPSIA component testing documented for zipper parts?


The component part testing rule lets a zipper supplier rely on its own test reports and certifications instead of the garment factory retesting every trim. To be usable, the report must come from an accredited laboratory, identify the exact part and material, state the test method and the result against the limit, and be traceable to the production lot through the purchase order or the supplier's certificate.

A workable file for one zipper contains the drawing with all materials, the bill of materials by homogeneous material, lead results for metal and coating, phthalate results where plasticised parts exist, and a statement that no component changed. If any input changes, the file is invalid and the part must be retested. Records must be retained for the period the rule requires, commonly five years.

The garment maker still issues the children's product certificate and remains responsible for the finished item. Pass the file over with the shipment, keep the version dates aligned, and re-check the file when the candidate list, the limits or the part itself changes.
