NMFC 181170 - Marine Engine Fuel Tanks in Crates | Class N/A

Note 181172: NOTE-Also applies on accompanying fittings and flexible fuel lines when in same container with tank.

To find the correct freight class for your shipment:

1. Confirm tanks are empty, vented, and fume-free; cap all ports and note “Empty, non-pressurized, no residue” on the BOL to align with NMFC Note 181172.
2. Use double-wall cartons with foam/blocking or a wood crate; brace filler necks and sending-unit flanges so impacts don’t deform thin walls or fittings.
3. Measure and record outside dimensions including skids; list NMFC 181170 and “non-automotive IC engine fuel tank” to avoid misclassification as auto parts.
4. For export or damp environments, use ISPM-15 lumber and VCI wrap for steel/aluminum tanks; band to a pallet, add up arrows and center-of-gravity marks.

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

• Non-hazardous when empty saves hazmat fees and paperwork, reducing total landed cost for marine and equipment suppliers.
• Crating and proper bracing cut puncture and dent claims, protecting margins on high-value tanks and avoiding costly returns.
• Clear NMFC citation (181170) with Note 181172 minimizes reclass fees, dispute time, and delivery delays.
• Square, stackable crates improve trailer cube utilization for LTL, often yielding better rates than irregular boxed parts.
