NMFC 171400 - Glass Fiber Rovings/Yarn or Strand | Class 70

To find the correct freight class for your shipment:

1. Identify the form and package: spooled rovings, boxed yarn, or bagged chopped strand. All move as packages at Class 70; print NMFC 171400 on the BOL.
2. Protect spools from unraveling and core crush: tape fiber ends, insert core plugs, add corner boards and top sheets, then stretch-wrap tightly to the pallet.
3. Control dust and moisture for chopped strand: use poly liners inside cartons or bags, keep pallets fully shrink-wrapped, and cover if docks are wet or humid.
4. Plan stable loads: avoid pallet overhang, interlock-stack cartons within manufacturer limits, and apply two polyester bands per pallet for LTL handling.

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

• Predictable rating: fixed Class 70 eliminates density checks, speeding quotes and reducing reclass fees.
• Lower compliance burden: fiberglass materials are non-hazardous, avoiding hazmat surcharges and paperwork delays.
• Reduced claims: abrasion- and moisture-aware packaging minimizes unraveling, contamination, and crushed cores.
• Improved rate leverage: tidy, palletized packages cube well for LTL, supporting better utilization and sharper freight rates.
