NMFC 66290 - Steel Troughs & Tanks Combo | Class 200

Note 66292: NOTE-Does not apply on open-top water tanks with drinkers or troughs installed in tank walls.

To find the correct freight class for your shipment:

1. Confirm the shipment fits NMFC 66290 and Note item 66292: a combined steel trough-and-tank assembly, with or without integrated fireboxes or heaters, packed as a single unit.
2. Use heavy corrugated boxes or robust packaged bundles on a pallet; strap and block to prevent flexing of long sides and protect rims, ports, and drain fittings.
3. If a heater or firebox is present, cap threaded openings, add foam or corrugated guards around housings, and mark the face as ‘Do Not Top Load’ to prevent crush damage.
4. On the BOL, list NMFC 66290, Class 200, piece count, and whether a heater/firebox is included to avoid reclass and speed up LTL rating.

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

• Fixed Class 200 means no density math—faster quoting and fewer billing surprises.
• One item covers units with or without heaters, reducing misclassification risk and reweigh/reclass fees.
• Non-hazardous status streamlines tendering and broadens carrier acceptance in agricultural lanes.
• Proper packaged presentation (boxed/palletized) cuts OS&D risk on long, rigid steel forms, lowering claims and downtime in farm operations.
