Packaging QA Checklist: Drop Tests, Carton Specs, and Damage Claims
7 min Read
TL;DR
- Define carton grade (5-ply/7-ply) + burst/ECT requirement.
- Specify inner protection (foam, air columns, honeycomb).
- Set drop test height + pass/fail criteria.

Cheap packaging becomes expensive very fast. Crushed corners, damaging returns, and chargebacks can kill your margin.
Why This Matters
Factories save money on 'hidden' costs like cardboard quality. A 'standard export carton' is often too weak for e-commerce shipping. You must specify the grade.
What to ask suppliers
- Q1What carton grade (ECT/burst) do you propose and why?
- Q2Can you show previous drop test data?
- Q3How do you protect corners and edges?
- Q4What is max weight per carton?
Red Flags
- No ECT/burst spec offered.
- “Same as before” but won’t share grade proof.
- Uses thin tape or inconsistent sealing.
- Avoids drop test discussion.
