NMFC 23900 – Carbon Black ≥17 PCF | Class 77.5

Note 23910: NOTE-Density must be shown by the shipper on the bill of lading and shipping order at time of shipment. If density is not shown and shipment is inadvertently accepted, charges will initially be assessed under the provisions of item 23940. Upon satisfactory proof of actual density, freight charges will be adjusted accordingly.

To find the correct freight class for your shipment:

1. Confirm density is ≥17 lb/ft³ for the shipping unit (bag, drum, or pallet). Example: 400 lb on a 40×48×20 in pallet = 22.2 ft³ → ~18 lb/ft³, qualifies for Class 77.5.
2. Select packaging that controls dust and staining: multi‑wall bags with liners, tight‑head drums, or Package 115. Stretch‑wrap with a top cap and opaque film to contain residue.
3. Palletize tightly with no overhang; use corner boards and a slip sheet. Mark the BOL with “NMFC 23900, Class 77.5 – carbon black, non‑hazardous” for clean rating and faster processing.
4. For boxes or drums, seal closures and use 4‑way entry pallets. Add a poly deck sheet to prevent black smudging on pallets and adjacent freight per carrier cleanliness policies.

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

• Predictable pricing: Fixed Class 77.5 for qualifying density helps nail down LTL quotes and avoid surprise reclasses.
• Lower compliance overhead: Non‑hazardous status eliminates hazmat fees and opens more carrier options and lanes.
• Fewer claims and accessorials: Dust‑tight packaging prevents staining‑related cleanup charges and reduces inspection delays.
• Better cube efficiency: Designing units to stay ≥17 lb/ft³ improves weight‑to‑space ratio, cutting cost per pound on repeat lanes.
