NMFC 120775 - Unit Heater Steel Enclosures | Class 250

Note 120776: NOTE-Applies only on enclosures or housings for heaters with extended-surface elements or burners, mounted with a motor-driven fan.

To find the correct freight class for your shipment:

1. Declare NMFC 120775, Class 250, non-hazardous on the BOL and describe the commodity as sheet-steel unit heater enclosures; no density entry is needed.
2. Pack each housing in a rigid carton or wood crate with foam or blocking; guard corners and mounting tabs, cap sharp edges, and brace long panels to prevent flex and dents.
3. Add corrosion protection with a VCI bag or light oil film, then fully seal the package; cover louvers and control cutouts to keep dust and hardware from entering.
4. For LTL handling, place sealed packages on a pallet, strap and stretch-wrap into one unit with zero overhang; use orientation labels and avoid stacking unless crated.

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

• Predictable pricing with a fixed Class 250 rating—fast quotes without density calculations.
• Lower claim risk by reinforcing thin-gauge steel panels, reducing rework and replacement costs.
• Accurate NMFC 120775 declaration curbs reclass and rebill exposure, strengthening audit compliance.
• Consolidated, palletized packages move cleaner through cross-docks, cutting handling time and accessorials.
