What freight class is sheet metal — flat stacked sheets?

Typically class 50–85

This commodity is classified by DENSITY, which means there is no single correct class for it — the class depends on how your particular shipment is packed. The range above is what typical shipments measure, not a ruling.

Confidence: medium. Sources broadly agree, but the range is wide — measure rather than assume. The binding answer is always the commodity's NMFC item as filed — this page is a planning estimate, not a classification ruling.

Why sheet metal — flat stacked sheets rates this class

Flat steel sheet is dense and cheap to ship. Formed, bulky parts (auto-body panels) are a different commodity entirely — much lighter, often Class 150–200.

How to get the real number

  1. 1.Measure the extreme outside dimensions of the loaded pallet — including any overhang and the pallet itself.
  2. 2.Weigh it loaded, pallet included.
  3. 3.Divide weight by cubic feet to get density in lb/ft³.
  4. 4.Look the density up on the July 19, 2025 scale — or let the calculator do all four steps.
