How to Determine Your Class
To find the correct freight class for your shipment:
- Ship tanks empty, depressurized, and purged; cap and seal all valves and ports, and include a purge/cleaning statement to support non-hazardous status.
- Choose packaging per move: loose on saddles with cribbing and chain tie-down points, or packaged on heavy-duty skids with blocking and banding to prevent roll.
- Mark center of gravity and orientation; use built-in lifting lugs or spreader bars. Avoid contacting the insulated shell with forks or chains.
- Shield insulation and jackets with edge protectors; add dunnage and V-boards for flatbeds. For docks, book crane or rigging instead of liftgates due to size.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Predictable pricing with fixed Class 85 reduces rating disputes and reclass fees.
- Allowance for loose or packaged shipments can cut crating costs while staying compliant.
- Proper prep minimizes damage to insulation and valves, lowering claims and downtime.
- Clear NMFC mapping speeds quotes and helps select the right equipment and carrier.
