NMFC 146330 - Listening Sonobuoys in Boxes | Class 100

To find the correct freight class for your shipment:

1. List the commodity as “Listening Sonobuoys, expendable, in boxes” on the BOL and use NMFC 146330 with Class 100 for consistent rating.
2. Pack units snugly with foam cradles or molded end caps to prevent cylinder movement, and add desiccant or moisture barriers for salt air or humid routes.
3. Palletize cartons with no overhang; use corner boards and two cross-straps plus stretch wrap to stabilize sensitive acoustic electronics.
4. For cross-border moves, confirm export controls and include NSN/part numbers or lot IDs on carton labels for traceability; note non-hazardous status.

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