How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm the fit: use this NMFC for non-portable air heaters with integral blowers or fans shipped in packages; portable space heaters should be classified elsewhere.
- Capture density for Item 170: measure L x W x H of the packaged unit and record the weight. Example: 48x40x36 in at 280 lb = 40 cu ft → 7 PCF.
- Package to protect moving parts: bolt the base to a skid, block and brace fan wheels and shafts, cap inlet/outlet openings, and crate oversized housings to resist side impacts.
- Document clearly on the BOL: “NMFC 114142 Air Heaters with Blowers, density item, subject to Item 170,” include PCF and packaging type, note accessories inside, and mark Non-Hazardous.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Density-driven rating lets you engineer packaging for higher PCF, reducing freight class and cutting LTL rates on heavy HVAC units.
- Bundling blowers, mounts, and hardware in the same package under one NMFC minimizes handling fees and lowers misclassification risk.
- Non-hazardous status broadens carrier options and avoids hazmat surcharges, improving lane coverage and quote speed.
- Damage-resistant crating and shaft bracing reduce claims and rework, which stabilizes transit times and protects project schedules.
