NMFC 75550 - Footwarmer or Hot Bottle Charges | Class 85

To find the correct freight class for your shipment:

1. Confirm HazMat status from the SDS, list NMFC 75550 Class 85 on the BOL, and include emergency contact info with applicable hazard markings and Keep Dry notices.
2. Pack charges in sturdy double‑wall boxes (UN performance packaging if required by SDS). Use sealed inner bags or liners to prevent leaks and moisture ingress, and add snug cushioning to avoid movement.
3. If palletizing cartons, align labels outward, keep arrows up, apply corner boards, and use tight stretch‑wrap or banding to prevent crushing or friction that could trigger activation.
4. Book with a HazMat‑authorized LTL carrier and segregate from incompatibles per the SDS. Example: retail cartons of chemical heat charges to an outdoor goods DC shipped as Class 85 without density rules.

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

• Predictable pricing with a fixed Class 85 rating reduces reclass disputes and streamlines rate shopping.
• Proper HazMat documentation and clear packing minimize fines, delay fees, and claim exposure for sensitive heat‑generating chemicals.
• Boxed shipments fit standard LTL networks, improving pickup availability and transit reliability even during seasonal demand spikes.
• Moisture‑barrier packaging and secure palletization limit accidental activation, cutting damage risk and downstream replacement costs.
