Notes
Note 123281: NOTE-Refrigeration or air conditioning compressors may be shipped secured on lift truck skids or pallets without being boxed or crated when having an additional lift truck skid or pallet on top of the handling unit to permit stacking. Entire handling unit must be secured together with strapping in both directions so as to withstand the normal rigors of the less-than-truckload environment.
How to Determine Your Class
To find the correct freight class for your shipment:
- Identify packaging as boxed or crated and confirm the shipment is a compressor for refrigeration or air conditioning; this article is density-based and subject to Item 170.
- Determine pounds per cubic foot: weigh the packed unit and use outside packaging size to calculate PCF; example: 24x24x20 in box at 150 lb equals about 22.5 pcf.
- Prep the unit for transit: cap suction/discharge ports, secure on a base, and use blocking, bracing, and tilt/shock indicators to protect against oil migration and impact.
- Note Item 123281 for specific note details and reference NMFC 123280 and the chosen packaging on the Bill of Lading to prevent reclass or inspection delays.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-driven pricing rewards compact, well-braced packs—reducing cube can move you into a lower class and cut LTL costs.
- Clear labeling (boxed vs. crated) and Item 170-compliant packaging minimizes reweigh/reclass fees and speeds carrier acceptance.
- Purpose-built crates for heavier or top‑heavy compressors reduce damage risk and downstream warranty costs.
- Accurate PCF and NMFC citation improve quote accuracy and lead to faster tendering across more non-haz carriers.
