NMFC 85500 - Gases or Cryogenic Liquids | Class N/A

To find the correct freight class for your shipment:

1. Confirm your product fits this inert gas/cryogenic family (e.g., argon cylinders, nitrogen or liquid nitrogen in dewars). If flammable or oxidizing, use the proper hazmat NMFC instead.
2. Use DOT-rated cylinders or vented dewars. Install valve caps and regulator guards, band or strap to skids, and mark Keep Upright and No Tipping to prevent valve damage.
3. Allow for boil‑off on cryogenic liquids via pressure‑relief devices; never seal dewars tight. Inform the carrier that controlled venting is expected during transit.
4. On the BOL, state container type, quantity, and tare/gross weights, plus empty/return status. Reference NMFC 85500 and Class N/A so the carrier applies the correct exception rating.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Faster rating decisions: A clear NMFC 85500 reference with container details speeds exception-class assignment and reduces reclass disputes.
• Lower surcharges where applicable: Non-hazardous entry for inert gases can avoid hazmat fees and minimize special handling charges.
• Reduced claims risk: Properly secured cylinders/dewars and upright handling notes cut valve impacts, leaks, and product loss.
• Better asset turns: Calling out returnable dewars and tanks streamlines reverse logistics, trimming rental, demurrage, and dwell time.
