NMFC 18490 - Steel Propane/Butane Cylinders | Class 92.5

To find the correct freight class for your shipment:

1. Use this NMFC when shipping empty, depressurized steel propane or butane cylinder fuel systems mounted on steel racks; note valves, regulators, tubing and fittings are included.
2. Cap each valve, plug tubing ends, and band the cylinders to the rack, then band the rack to a skid; block and brace to stop roll or sway. Example: two rack assemblies strapped to a 48×40 pallet.
3. Record footprint and overall height for quotes and dock handling; density isn’t needed for classing, but dimensions ensure LTL compatibility and avoid oversize fees.
4. On the BOL, state “NMFC 18490 – Class 92.5 – Nonhazardous” and request no top-load; add corner boards to shield regulators, gauges, and manifolds during transit.

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

• Fixed Class 92.5 simplifies rating and prevents reclass/reweigh disputes, cutting surprise charges.
• Nonhazardous status for empty systems broadens carrier choices and avoids hazmat surcharges.
• Steel rack mounting lowers damage risk, reducing claims and keeping automotive upfits and fleet installs on schedule.
• Clear NMFC mapping speeds carrier acceptance and bid pricing, improving rate predictability for LTL lanes.
