NMFC 170350 - Fiberboard & Composition Roofing | Class 70

To find the correct freight class for your shipment:

1. Protect edges and faces: use corner protectors, slip sheets, and a top cap when bundling fiberboard wallboard with roofing. Strap with padding to avoid crushing the board.
2. Choose packaging by route: crates for mixed wood/fiberboard sets or rough handling, tight packages for uniform bundles. Keep panels flush with pallet—no overhang on 4x8 sheets.
3. Moisture matters: wrap bundles in poly or use kraft plus stretch film. Add a waterproof bottom sheet to guard fiberboard from dock or trailer condensation.
4. Mark documents and labels: show NMFC 170350, Class 70, packaging type (package or crate), and note “with or without wood strips.” Place labels on two adjacent sides.

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

• Fixed Class 70 eliminates density calculations, reducing reclass risk and unexpected fees on LTL moves.
• Packaging flexibility—crates or tight bundles—lets you balance protection and cost based on lane conditions and claim history.
• Single code for combined wallboard and composition roofing simplifies quoting, consolidates SKUs on the BOL, and speeds tendering.
• Predictable rating supports accurate budgeting for distributors and roofing contractors, improving rate negotiations and lead-time planning.
