NMFC 170000 - Roofing or Siding Materials | Class N/A

To find the correct freight class for your shipment:

1. Identify the exact product and build (asphalt shingles, metal roofing sheets, vinyl siding, fiber‑cement boards, or underlayment rolls) and locate its specific NMFC item under this group; don’t bill the group header on the BOL.
2. Unitize to prevent overhang: strap shingles in tight bundles on 40x48 pallets with corner boards and a top sheet; crate long metal panels with end protection and edge guards; add foam interlayers and full stretch‑wrap for brittle fiber‑cement.
3. Mark length and center of gravity, keep stack height under 48 inches when possible, and provide fork‑tine clearance; avoid mixed lengths that create pallet overhang and length fees.
4. Document material type, packaging (e.g., “vinyl siding panels, palletized”), piece count, and the item‑level NMFC number; request accessorials for long freight, liftgate, or residential delivery as needed.

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

• Accurate item‑level classification within the roofing/siding group prevents reclass fees and billing disputes, improving quote accuracy and cash flow.
• Damage reduction through packaging tuned to material behavior—brittle fiber‑cement and coated metal panels—cuts replacement costs and claim rates.
• Optimized unit loads (standard pallets, no overhang, stackable packs) help avoid length and non‑stackable surcharges, lowering LTL transportation spend.
• Non‑hazardous status expands carrier options and simplifies tendering, enabling faster pickups and more competitive freight rates.
