NMFC 26820 - Radiators/Unit Ventilators | Class N/A

Note 26821: NOTE-Also applies on Ceiling or Wall Panel Radiators.

To find the correct freight class for your shipment:

1. Use NMFC 26820 when shipping radiators or unit ventilators that are fully enclosed in a box or wood crate; note “boxed/crated” on the BOL.
2. Protect fragile coils and fins: add foam end blocks, cap all water/steam connections, and secure fan assemblies; example: panel radiator double-cartoned with corner guards.
3. Measure the exterior of the box/crate and record actual piece count; band the container to a 4‑way pallet with zero overhang for forklift handling.
4. Review the NMFC note for item 26821 to confirm the article description fits your model; attach photos to prevent reclassification.

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

• Correct use of 26820 reduces inspection delays and reclass fees because the article is identified as radiator/unit ventilator NOI in boxed or crated packaging.
• Damage prevention through proper crating and coil protection cuts claim costs on finned cores, motors, and control panels.
• Rate accuracy improves since density is not the driver here; packaging and commodity drive the class, streamlining LTL quotes.
• Planning liftgate or residential service up front avoids redelivery charges often seen with heavy cast‑iron sections.
