NMFC 123290 - Iron/Steel Condensers & Coolers | Class 77.5

To find the correct freight class for your shipment:

1. Verify eligibility: iron or steel units, no fins, and shell-or pipe-type construction. Exclude aluminum or finned models to avoid misclassification.
2. Remove detachable fittings and pack them separately in sturdy boxes, crates, or drums. Label as detached fittings for NMFC 123290 and secure with internal dunnage.
3. Mount the exchanger on a skid, block and band it tight, cap all nozzles, and fully drain any residual brine or water. Add tilt and shock indicators for delicate tube bundles.
4. Print NMFC 123290, Class 77.5 on the BOL, include piece count and exact dimensions/weight, and request needed accessorials (liftgate, appointment) for heavy machinery.

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

• Predictable Class 77.5 rating streamlines quoting and rate negotiations, reducing time spent on density calculations.
• Compliant boxing/crating of detached fittings minimizes reclass/reweigh fees and lowers claim exposure for tube sheet or nozzle damage.
• Non-hazardous status shortens tendering and documentation cycles, helping shipments move faster through LTL terminals.
• Clear scope—iron/steel, no fins—prevents costly misrates versus finned coils or non-qualifying materials, keeping freight budgets accurate.
