Buyer Alert: Sample Approval Gaps Still Top Cause of First-Order Packaging Rework

Across cartons, bags, and rigid boxes, suppliers say most first-order rework traces to incomplete sample approval: missing ECT or caliper, unapproved print color, or handle/structure changes made verbally.

A signed sample sheet with photos, measurements, and material IDs prevents “almost the same” bulk shipments. Digital proofs alone are not enough for structural packaging.

Buyer takeaways

Use a written sample approval form with measurements.

Photograph approved samples and retain one golden sample.

Ban verbal-only changes after approval.
