Narrative Summary

I shipped a 45-pound box of retail inventory to a boutique. I used a 44-ECT single-wall box. When it arrived, the top of the box was completely crushed inward, destroying the fragile inventory inside. I filed a claim, but UPS denied it. They claimed that the packaging was "insufficient to withstand the normal compressive forces of vertical stacking in a delivery vehicle," blaming my box for collapsing under the weight of other packages.

The Resolution Strategy

Carriers stack heavy packages on top of lighter ones all the time. When the bottom box inevitably crushes, they blame the shipper for not using a stronger box, masking their own poor loading practices.

The Authori shipping appeal strategy relied on a deep technical reading of the Edge Crush Test (ECT) metrics found in UPS Packaging Guidelines § 3.1.

The appeal letter argued that while an ECT rating evaluates vertical compression strength, it is engineered based on normal, proportional load distribution. A 44-ECT box is designed to hold 40 pounds, but it is not designed to act as a structural base for 100 pounds of external freight. The appeal asserted that the complete vertical collapse of an undamaged, 44-ECT rated box is physical proof that UPS network handlers improperly loaded excessive, non-compliant weight on top of the parcel. Faced with this structural reality, UPS reversed the denial and paid the claim.
