NMFC 44500 - Bulk Flammable Liquids | Class N/A

Note 44501: NOTE-Applies on materials regulated by the U.S. Department of Transportation as a Hazard Class 3: Flammable Liquid; or Combustible Liquid in bulk containers; as defined in 49 CFR 173.120 and required to bear a notice to that effect on bills of lading and packaging.

To find the correct freight class for your shipment:

1. Confirm the product’s hazard details from the SDS (Sections 2 and 14). Determine if it’s flammable or combustible based on flash point, then select the proper UN shipping name and packing group.
2. Use U.S. DOT-authorized bulk packaging over 119 gallons, such as UN31HA1 composite IBCs or UN31A steel IBCs. Inspect valves, gaskets, and closures, and leak‑test before tendering.
3. Apply all marks, labels, and placards required for bulk Class 3 or combustible liquids. Prepare hazmat shipping papers with UN ID, proper shipping name, hazard class, packing group, quantity, and a 24/7 emergency phone number.
4. Quote and book with hazmat‑approved carriers that accept bulk IBCs. Reference NMFC 44500 and review Note item 44501 for any special conditions, segregate from oxidizers, and secure totes to prevent movement or valve damage.

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

• Correctly using NMFC 44500 reduces reclass fees and rebills, keeping landed costs predictable on bulk solvent, fuel, and alcohol moves.
• DOT‑authorized IBCs enable higher volumes per shipment versus drums, lowering per‑gallon freight, handling time, and claim exposure.
• Accurate hazmat documentation and placarding accelerate dock throughput and carrier acceptance, cutting pickup delays and detention.
• Compliance with bulk Class 3 and combustible rules minimizes spill risk and regulatory fines, safeguarding operations and insurance standing.
