NMFC 129940 - Shock Absorbers, Parts | Class 70

Note 129941: NOTE-Does not apply on air springs. For applicable provisions, see item 177905, 'Air Springs.'

To find the correct freight class for your shipment:

1. Confirm the item fits NMFC 129940: complete shock absorbers, struts, or parts made of rubber or steel shipped in packages. Review Note 129941 for any exceptions or special conditions.
2. Treat as hazardous. Declare gas- or oil-charged shocks on the BOL, include a 24/7 emergency contact, apply required hazmat markings/labels, and use carriers authorized for hazmat.
3. Package to prevent leaks and impact: cap all ports, protect piston rods, use absorbent liners and poly bags inside double-wall cartons, then palletize, strap, and shrink-wrap with orientation arrows.
4. Document precisely: list piece count and package type, net/gross weight, and include the manufacturer safety information if provided. Schedule pickup windows to allow hazmat checks at the dock.

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