NMFC 40650 - Ground Petroleum Coke Flour | Class 50

To find the correct freight class for your shipment:

1. State the commodity on the BOL: “Flour, ground petroleum coke, NMFC 40650, Class 50, non-hazardous.” No density needed for rating.
2. Use sift‑proof, double‑wall corrugated boxes with a sealed 2–4 mil poly liner. Example: a 40 lb fill in 275# test with H‑taping to stop fines leakage.
3. Palletize tight: stretch‑wrap 3–5 turns, add corner boards, use a top sheet, and keep seams upright. Cap pallets and avoid over‑stacking to limit dust escape.
4. Protect from moisture and static. Keep boxes dry, consider antistatic liners for ultrafine material, and time pickups to avoid rain exposure.

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

• Fixed Class 50 simplifies quoting across carriers and curbs reclass charges.
• Non‑hazardous status avoids hazmat paperwork and surcharges, speeding tender to pickup.
• Standardized boxed packaging reduces OS&D for fine powders and streamlines warehouse handling.
• Carbon Group commodity familiarity improves carrier acceptance and transit reliability.
