NMFC 36040 - Double-Hung Sash Channel Sets | Class 77.5

To find the correct freight class for your shipment:

1. Mark boxes clearly as “Aluminum Channel Sets with Steel Sash Balance” and keep each length set grouped by window size to prevent mismatched pairs and bent ends.
2. Palletize boxes flat on a 48x40 pallet with zero overhang; add edge protectors and two polyester bands, then stretch-wrap in a crosshatch to keep slender channels from shifting.
3. List NMFC 36040, Class 77.5 on the BOL and note “boxed, building metalwork” so carriers don’t request density or reweighs for this simple-class item.
4. Use caps or cardboard collars on channel ends and avoid stacking heavy goods on top; treat as precision metal hardware, not generic lumber.

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

• Fixed Class 77.5 means predictable LTL rates and fewer reclass fees, improving quote accuracy for project bids.
• Boxed packaging aligned to building metalwork standards reduces damage to delicate channels and sash balances, lowering claims and replacement costs.
• Simple classification with no density required speeds tendering and minimizes inspection delays across regional carriers.
• Consistent NMFC coverage supports multi-location contractors ordering varied window sizes, streamlining procurement and freight budgeting.
