Notes

Note 148491: NOTE-Applies on packing in the piece, made of rubber, gum or similar compounds, including all packing other than asbestos packings, covered or treated with rubber, gum or other similar compounds.

How to Determine Your Class

To find the correct freight class for your shipment:

  1. Match packaging to the material: coil plastic cord neatly in rigid boxes, ship asphalt-coated paper/cloth as strapped roll packs with edge protection, place rubber compounds in lined boxes to prevent sticking, and crate vegetable fiber with a moisture barrier.
  2. Determine density to select the freight class under Item 170. Example: 42 lb on 5.0 cu ft equals 8.4 pcf; list pcf and NMFC 148490 on the BOL for fast carrier classing.
  3. Stabilize and protect: keep asphalt-coated rolls upright with end caps, use slip sheets and stretch film, avoid heat that can soften binders, and wrap rubber compounds to contain oil or tack.
  4. Document clearly: note NMFC 148490 and the specific material (plastic cord, asphalt paper/cloth, rubber compound, vegetable fiber), include piece count and pallet dimensions/weight, and mark non-hazardous.

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

Business Value

  • Dialing in density can shift class within 50–400, cutting LTL spend by hitting better breakpoints and reducing reclass fees.
  • Non-hazardous designation streamlines carrier acceptance and avoids hazmat surcharges, shortening transit planning and tender times.
  • Material-appropriate packing lowers claims on rolls and tacky compounds, preserving product integrity and minimizing OS&D costs.
  • Accurate NMFC labeling and density data reduce reweighs, accelerate dock processing, and improve quote-to-invoice accuracy.
