NMFC 40660 - Flour, NOI, Boxes | Class 85

To find the correct freight class for your shipment:

1. Reference NMFC 40660 and Class 85 on the BOL, describing the commodity as Flour, NOI (Carbon Group) and selecting boxes as the packaging.
2. Use lined, well-sealed corrugated boxes to prevent sifting; add inner plastic liners and tape all seams to contain fine graphite/carbon powder.
3. Palletize evenly with a cap sheet, corner boards, and tight stretch wrap; limit stack height to protect box integrity and reduce dust escape.
4. Keep boxes dry and clean; add desiccants or poly liners if humidity is a concern and mark cartons with orientation and “Do Not Top Load” when appropriate.

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

• Predictable pricing with fixed Class 85—no density calculations or reclass surprises for boxed powder.
• Non-hazardous status removes hazmat fees and simplifies carrier onboarding across standard LTL networks.
• Box packaging supports small-lot replenishment to foundries, additive manufacturers, and labs, lowering packaging and handling costs versus drums.
• Accurate NMFC usage (40660) reduces inspection disputes, cuts delay risk, and helps maintain cleaner claims performance.
