Classification Details

NMFC Description Class
170570.00 Siding, asphalt composition, or fiberboard faced or coated with asphalt and roofing granules, or fiberboard faced or coated with resin composition, see Note, item 170552, in packages 55

How to Determine Your Class

To find the correct freight class for your shipment:

  1. List NMFC 170570, Class 55 on the BOL; density is not required when the siding is shipped in packages.
  2. Bundle panels flat on a 48x40 pallet with corner protectors, slip sheets, and stretch wrap to keep roofing granules from scuffing adjacent bundles.
  3. Use wide nylon or steel bands with edge guards; avoid fork tine pinch by using full-length fork extensions when lifting long bundles.
  4. Keep dry before pickup and cover with a pallet cap in rainy or hot conditions; asphalt/resin faces can soften or stick without a separator.

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

Business Value

  • Fixed Class 55 rating simplifies quotes and reduces reclass fees versus density-based commodities.
  • Package-defined eligibility means predictable access to LTL networks and fewer hazmat surcharges.
  • Damage reduction from proper bundling lowers claim costs on granule-faced edges and corners.
  • Standard 48x40 footprints optimize cube and avoid oversize penalties, improving freight rates across lanes.
