Where 12–13.5 lb/ft³ lands on the current scale

Typical shipments of this commodity stay inside one class band, so the estimate above is comparatively safe — but still measure before quoting.
How to get the real number
- 1.Measure the extreme outside dimensions of the loaded pallet — including any overhang and the pallet itself.
- 2.Weigh it loaded, pallet included.
- 3.Divide weight by cubic feet to get density in lb/ft³.
- 4.Look the density up on the July 19, 2025 scale — or let the calculator do all four steps.
