NMFC 23820 - Dry Mineral Blacks & Peat Char | Class N/A

To find the correct freight class for your shipment:

1. State the item clearly on the BOL: “Blacks, dry mineral earth or peat char—other than dry earth paint,” to prevent misclassification and re-bills.
2. Use sealed packaging to contain dust: poly‑lined paper bags (e.g., 50 lb), FIBCs/supersacks, or tight‑head fiber drums. Stretch‑wrap and add a top sheet to stop rub‑off onto nearby freight.
3. Palletize evenly and protect edges with corner boards; add slip sheets to reduce staining transfer. Mark pallets with “powder—keep dry” and avoid loading next to white or food goods.
4. Control moisture and contamination: use liners or desiccants for humid routes and ensure trailers are swept clean before loading to keep product integrity.

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

• Accurate NMFC description reduces reclass fees and contamination claims from black dust or rub-off.
• Non-hazardous status eliminates hazmat surcharges and simplifies paperwork, improving carrier acceptance for LTL.
• Unitized packaging (supersacks or drums) lowers handling touches, speeds docks, and can improve rate negotiations per hundredweight.
• Clean, sealed packs cut OS&D incidents and cleanup charges, protecting margins and customer quality metrics.
