How to Determine Your Class

To find the correct freight class for your shipment:

  1. List the alloy and classification on the BOL: “NMFC 37230, Class 85 – non‑ferrous (e.g., copper, brass, bronze)” to prevent steel misrating.
  2. Package in bundles or cartons with nose/edge protection and face sheets; for mineral‑filled anti‑slip inserts, use rigid cartons or light crates to prevent cracking.
  3. Palletize lengthwise with blocking, edge protectors, and non‑slip dunnage; strap securely, wrap, and mark Do Not Stack if treads can bow or dent.
  4. Provide total weight and outer dimensions for the quote and label, and select “packages” as the packaging type since the class is fixed.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

Business Value

  • Fixed Class 85 removes density calculations, speeding quotes and reducing billing adjustments.
  • Clear NMFC 37230 labeling distinguishes non‑ferrous treads from steel, avoiding misclass charges and metal‑type surcharges.
  • Damage‑smart packaging (edge protection, rigid cartons) cuts claims and keeps construction schedules on track.
  • Predictable costs help stair fabricators and distributors bid confidently and control margins on multi‑stop LTL lanes.
