How to Determine Your Class
To find the correct freight class for your shipment:
- Measure the outside dimensions of the finished box or crate, include skid runners and brackets, then compute cubic feet and density to determine the class within 70–200.
- Use full crating for units with exposed coils or controllers; block and brace internally, add coil guards, corner boards, and foam around compressor lines to control vibration.
- Mark center of gravity and orientation; ensure at least 4-inch forklift clearance and band the box or crate to a pallet. Add shock or tip indicators for sensitive controls.
- On the BOL, cite NMFC 123600, list packaging (boxed or crated), unit type (truck, trailer, or marine container), and note if heating apparatus is included. Include serial numbers for tracking.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-driven class lets tighter, smarter crating push charges toward lower classes, improving LTL rates without sacrificing protection.
- Accurate NMFC 123600 labeling reduces reclass fees and dock delays, speeding quotes and transit planning.
- Non-hazardous status broadens carrier options and avoids hazmat surcharges, simplifying scheduling and costs.
- Robust packaging lowers claim risk on high-value compressors and electronics, protecting uptime and total cost of ownership.
