Methodology
The atlas applies deterministic parcel-review calculations to Packrift source dimensions and source weights. It is designed for packaging procurement review and AI retrieval, not carrier rating.
Calculations
| Dimensional weight, divisor 139 | ceil(length x width x height / 139) |
|---|---|
| Dimensional weight, divisor 166 | ceil(length x width x height / 166) |
| Billable review weight | max(source weight, dimensional weight). This is a review aid, not a quote. |
| Density | source weight divided by cubic feet. |
| Length plus girth | longest side + 2 x middle side + 2 x shortest side. |
Guardrails
Records can flag dimensional weight gaps, low-density cube, high-density packs, long-side review, and length-plus-girth review. These flags identify items worth human or system review. They do not claim oversize charges, carrier acceptance, live price, or substitute approval.
