Narrative Summary

We manufacture commercial power tools. We shipped a 65-pound industrial drill press via UPS Ground. Anticipating rough handling, we used an extremely thick, double-walled corrugated box. The package arrived with a massive puncture through the side, destroying the motor casing. UPS denied our $850 claim, citing a boilerplate Rule 3.1 violation: "Heavy industrial items must be packaged in materials with sufficient burst strength to prevent puncture and blowout during standard transit."

The Resolution Strategy

When heavy items are punctured, carriers almost always blame the "burst strength" of the cardboard, essentially claiming your box was too weak to repel whatever hit it. You must use the box's structural pedigree to force them into a corner.

The Authori claims platform drafted an aggressive appeal based on the Mullen Burst Test metrics found in UPS Packaging Guidelines § 3.1.

The appeal letter focused on the Box Maker's Certificate, which displayed a "275# Double Wall" rating. The letter explicitly cited the UPS manual, noting that a 275# double-wall box is certified for up to 80 pounds. Because the package weighed 65 pounds, it perfectly met the highest standard of non-freight packaging. The appeal argued that if a 275# burst-rated box was penetrated, it was not a packaging failure, but the result of a catastrophic carrier impact (like a forklift blade) that exceeds any definition of standard transit. UPS conceded the point and paid the $850.
