How to Determine Your Class

To find the correct freight class for your shipment:

  1. Match the NMFC: ship unglazed bow or bay window frames or sash in sealed boxes or sturdy wood crates to qualify under NMFC 34775, Class 300.
  2. Protect the curve: use curved saddles or custom blocking to support the radius, add corner protectors, and brace rails to prevent racking during LTL handling.
  3. Label and handle: mark cartons or crates with “Do Not Stack” and “Unglazed—Fragile Millwork,” and secure to a pallet for forklift clearance and stability.
  4. Plan accessorials: long pieces often exceed 96 inches—prearrange long-freight handling, limited access, residential delivery, or liftgate to avoid delays.

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

Business Value

  • Predictable rating: fixed Class 300 removes density math, enabling faster, cleaner LTL quotes for millwork dealers and contractors.
  • Lower reclass risk: packaging that mirrors the NMFC description (boxes or crates, no glass) minimizes inspection issues and reweigh/reclass fees.
  • Fewer damage claims: rigid crating and radius bracing cut torsion and edge crush, reducing remakes and keeping installation schedules on track.
  • Smoother bidding: standardized class streamlines pricing for multi-stop showroom and jobsite deliveries, improving margin control on fenestration projects.
