Notes
Note 85901: NOTE-Applies on materials regulated by the U.S. Department of Transportation as a Hazard Class 2, Division 2.3, Poison Gas, as defined in 49 CFR 173.115 and required to bear a notice to that effect on bills of lading and packaging.
How to Determine Your Class
To find the correct freight class for your shipment:
- Confirm the PIH designation, UN/NA number, and hazard zone, then reference NMFC item 85901 to determine the exact class for your specific gas blend.
- Package in compliant metal cylinders or drums with valve protection; if using smaller containers, overpack in sturdy boxes or crates and secure to a pallet with blocking and bracing.
- Provide complete hazmat paperwork: proper shipping name (Class 2.3), any subsidiary risks (2.1 flammable or 8 corrosive), emergency contact, and current cylinder test/inspection dates and SDS.
- Choose carriers authorized for PIH 2.3, notify terminals of restricted access or ventilation needs around petroleum sites, and schedule pickups to minimize dwell and exposure.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Accurate NMFC alignment with 85901 prevents reclassification, hazmat rejections, and costly penalties for PIH shipments.
- Carrier acceptance improves when documentation and packaging match PIH 2.3 requirements, keeping refinery and pipeline projects on schedule.
- Clean data drives predictable quoting and hazmat surcharge budgeting for gas cylinders or drums, improving lane and mode decisions for LTL.
- Safer handling and fewer damage or leak claims by using approved containers and overpacks, reducing insurance deductibles and OS&D disputes.
