How to Determine Your Class

To find the correct freight class for your shipment:

  1. Bundle long members tightly with banding and corner protectors; add dunnage every 4–6 ft for fork access and to prevent sag. Use edge boards on glulam/LVL to avoid strap marks.
  2. Square the bundle and cap both ends so no pieces overhang. Note actual overall length on the BOL; many carriers apply surcharges beyond 12 ft.
  3. Wrap laminated wood in breathable poly or kraft with a moisture barrier, and tape over strap contact points. Mark fragile or finish-grade beams as “Top Load Only.”
  4. Print NMFC 113120 and Class 60 on the BOL, with piece count per bundle and total weight. This speeds inspections and helps avoid reclass or delay.

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

Business Value

  • Fixed Class 60 simplifies quotes and can beat density-based pricing for dense glulam and LVL components.
  • Accurate NMFC on paperwork reduces reclass fees and keeps framing and roofing schedules on track.
  • Unitized bundles cut handling touches and damage, lowering OS&D claims on custom-cut rafters and joists.
  • Clear length disclosure prevents extreme-length fees and re-delivery, preserving margins on contractor drop-offs.
