Packaging QA Checklist: Drop Tests, Carton Specs, and Damage Claims

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

  • Q1
    What carton grade (ECT/burst) do you propose and why?
  • Q2
    Can you show previous drop test data?
  • Q3
    How do you protect corners and edges?
  • Q4
    What 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.

Step-by-Step Verification Checklist

  • 1
    Define carton grade (5-ply/7-ply) + burst/ECT requirement.
  • 2
    Specify inner protection (foam, air columns, honeycomb).
  • 3
    Set drop test height + pass/fail criteria.
  • 4
    Define carton dimensions + weight limit per box.
  • 5
    Require edge crush reinforcement for corners.
  • 6
    Specify tape type and sealing method.
  • 7
    Add carton marking and orientation arrows.
  • 8
    Require packing photos + random carton compression checks.
