Note 34781: NOTE-Also applies on accessorial hardware, provided the combined weight of such hardware does not exceed 15 percent of the weight on which charges are assessed.

How to Determine Your Class

To find the correct freight class for your shipment:

  1. State “not glazed” on the BOL and reference Note 34781 so carriers rate the correct NMFC item.
  2. Bundle or crate frames and sashes with diagonal bracing, foam edge guards, and corner protectors; e.g., an 84×48 vinyl frame bundle on a 96" skid with 2× lumber frame.
  3. Load long pieces vertically with blocking or flat on a skid with zero overhang; mark tall bundles “Do Not Stack” and ensure forklift entry on both ends.
  4. Separate hardware, screens, and trim; wrap sashes to prevent rub marks and photograph packaging before tender to support claims if needed.

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

Business Value

  • Clear “not glazed” notation avoids glass handling charges and reclass fees, stabilizing LTL costs.
  • Rigid bracing and proper bundling reduce flex-related damage, cutting replacements and jobsite delays.
  • Crated or palletized units move faster across docks, improving transit times to dealers and installers.
  • Referencing Note 34781 streamlines carrier rating and post-audit reviews, reducing administrative back-and-forth.
