Notes
Note 123651: NOTE-Applies only on cooling or freezing assemblies or apparatus, such as those used for cooling or freezing rooms or display-type refrigerators or freezers.
How to Determine Your Class
To find the correct freight class for your shipment:
- Select packaging to match size and fragility: heavy-duty box with foam, corner posts, and a skid for smaller coolers; fully framed crate with bolted runners for larger institutional units.
- Calculate density to set the class within 85-300. Measure the full outside dimensions (including pallet/crate), compute cubic feet (L×W×H ÷ 1728), weigh, then divide. Example: 48×40×36 in at 240 lb = 40 cu ft → 6 pcf.
- Protect delicate components: cap copper stub-outs, shield coil fins with spacers, secure fan guards, and brace drain pans. Use Keep Upright and Center of Gravity labels to guide handling.
- Strap the unit to the skid in two directions and block under the frame to prevent sway. For walk-in freezer applications, choose crate builds that allow forklift tine clearance and no top stacking.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Lower freight spend by improving density—tightening crate dimensions or using shorter skids can move you to a lower class within the 85-300 range.
- Fewer damage claims through rigid crating around coils and fan assemblies, saving replacement costs and avoiding service delays at restaurants, campuses, and food facilities.
- Faster, cleaner quotes: providing NMFC 123650 with verified weight, dimensions, and packaging type reduces reclass fees and carrier inspections.
- Predictable timelines for project installs—properly packaged non-hazardous unit coolers move smoothly in LTL networks, minimizing reschedules and labor overruns.
