Notes
Note 123576: NOTE-Applies on machines designed to reclaim, recycle or recover refrigerant gas or liquid.
How to Determine Your Class
To find the correct freight class for your shipment:
- Calculate density before you book. Convert package volume to cubic feet (L×W×H in inches ÷ 1728) and divide weight by that number; e.g., 95 lb in 3.0 cu ft = 31.7 pcf.
- Package in sturdy boxes or fully enclosed crates that meet NMFC Item 170. Block and brace internals, add skid runners for forklifts, and use Tip-N-Tell for tilt-sensitive units.
- Prepare the machine: ship the unit empty, cap ports, secure hoses, and place absorbent pads for any residual oil. Do not include any refrigerant cylinders in the same package.
- Label the BOL with NMFC 123575, weight and cube, and reference notes items 123576/123577 if applicable. Photograph packaging to support claims and avoid reclass disputes.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Optimized density can drop the class and lower LTL rates—tighter crating that reduces cube often pays back in immediate freight savings.
- Packaging to Item 170 reduces carrier exceptions, cutting reweigh/reclass fees and accelerating transit through machinery-handling terminals.
- Non-hazardous status streamlines tendering and avoids hazmat surcharges, improving carrier options and pickup flexibility for HVAC service projects.
- Clear documentation (NMFC 123575 on the BOL, verified dimensions) prevents billing corrections and shortens cash cycles with fewer invoice disputes.
