How to Determine Your Class

To find the correct freight class for your shipment:

  1. List NMFC 181840 on the BOL and describe as “pipe insulation tape, rolls in inner cartons in boxes” to match the tariff wording and prevent reclass.
  2. Palletize boxed rolls flat, avoid over-compression of layers, and use corner boards/top caps so the cork-asphalt tape doesn’t deform during transit.
  3. Protect from extreme temps: the asphalt/petroleum binder can soften in heat and stiffen in cold. Choose service that avoids hot trailers or freezing exposure.
  4. Stretch-wrap to keep cartons dry and intact, label all sides, and keep pallet footprints tight to reduce cubic charges for LTL.

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

Business Value

  • Fixed Class 70 rating makes quotes predictable and reduces the risk of carrier reclassification fees.
  • Non-hazardous status avoids hazmat paperwork and surcharges, improving total landed cost.
  • Boxed-roll packaging lowers damage risk, cutting claim rates and replacement costs for HVAC and pipe insulation jobs.
  • Clear NMFC alignment speeds tendering and pickup scheduling, shortening lead times for maintenance and construction projects.
