Narrative Summary

I design and sell large 3D-printed architectural models. I shipped a lightweight but bulky $150 model using standard EPS (expanded polystyrene) packing peanuts, ensuring there were at least three inches of peanuts on all sides. When the package arrived, the box was heavily caved in on one side, snapping the plastic model inside. USPS denied my claim, using a boilerplate response that stated "loose-fill dunnage is insufficient for preventing compressive damage to hollow items."

The Resolution Strategy

Automated claims systems hate packing peanuts. If a box caves in, adjusters assume you didn't pack the peanuts densely enough, leading to "settling" that allowed the box to crush.

The resolution strategy utilized the Authori claims platform to generate an appeal anchored on DMM Section 601.2.1, focusing specifically on shock distribution.

The drafted appeal letter detailed the "overfill and settle" method used during packing, confirming the peanuts were compressed prior to sealing the box. It successfully argued that for a lightweight item (under 2 pounds), EPS loose-fill is the exact federally approved standard for shock absorption. By proving the void fill density met DMM requirements for the specific weight class of the item, the appeal forced USPS to admit the caved-in box was the result of a severe external crush load exceeding normal mail processing limits. They approved the $150 claim.
