NMFC 25400 - Boilers, Furnaces & Stoves | Class N/A

To find the correct freight class for your shipment:

1. Map the unit to the correct named NMFC item under this group (e.g., cast‑iron boiler on a skid vs. sheet‑metal furnace in a carton) before quoting.
2. Build stout pallets or crates: block burners and heat exchangers, cap all ports, strap with steel banding, protect fins and flue collars, and mark Top Heavy/Do Not Stack.
3. Drain residual oils and water from used equipment, remove loose ash, and bag hardware so the shipment stays non‑hazardous and inspection‑ready.
4. For parts and radiators, wrap each piece, interleave corrugate to prevent metal‑on‑metal contact, then band to create a single, countable handling unit.

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

• Selecting the precise item within the 25400 group prevents reclass and rebill fees, keeping inspections brief and margins intact.
• Purpose‑built crating for heavy, top‑heavy heating units reduces damage claims and avoids costly delays or re‑delivery events.
• Clear specs on material, size, and packaging let carriers price accurately, often yielding better LTL rates for dense cast‑iron shipments.
• Maintaining non‑hazardous status by draining and cleaning eliminates hazmat surcharges and speeds terminal handling.
