NMFC 187520 - Metal Cooling Tower Troughs | Class 85

To find the correct freight class for your shipment:

1. Nest troughs lip-to-lip with corrugated pads between each piece, then strap tightly; note the nested quantity on the BOL and packing list.
2. For boxes, use double-wall cartons with foam edge guards around flanges and wood cleats inside so the metal cannot shift during LTL handling.
3. For crates, block and brace the troughs to the skid or bolt through mounting holes; add directional arrows so the open side faces up to prevent deformation.
4. Label freight as “metal cooling tower troughs, nested, NMFC 187520, Class 85” to avoid reclass, and list outer box/crate dimensions even though class is fixed.

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

• Fixed Class 85 removes density calculations, speeding quotes and reducing rating disputes.
• Nested packaging lowers cube and can improve LTL rates without changing the assigned class.
• Boxed or crated protection cuts abrasion and bend claims on thin-gauge metal components.
• Non-hazardous status broadens carrier options and simplifies routing across networks.
