NMFC 138640 - Drilling Mud Compounds | Class 50

To find the correct freight class for your shipment:

1. Use Class 50 with weight-based rating: record accurate gross weight for bags or drums, then quote without density. Provide dimensions only if the carrier needs space protection.
2. Match packaging to the SDS: UN-rated drums with tight bungs for liquids; heavy-duty, moisture-resistant bags for powders. Strap and stretch-wrap to pallets, add corner boards and a top slip sheet.
3. Declare hazmat correctly: list the proper shipping name, UN/NA number, packing group, and emergency contact. Apply labels/placards and tender to hazmat-authorized LTL carriers.
4. Prevent leaks and contamination: line pallets with absorbent pads, use drum rings or pallet cradles, and keep bagged goods dry. Avoid high stacking that can crush bags or pop drum lids.

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

• Predictable pricing: fixed Class 50 avoids density disputes and stabilizes LTL quotes.
• Lower risk costs: compliant hazmat paperwork and sturdy packaging reduce delays, fines, and spill cleanup charges.
• Fewer claims: palletized, protected bags and drums minimize punctures, moisture damage, and product loss.
• Smarter routing: consolidate to hit carrier weight breaks and choose hazmat-capable lanes serving oilfield yards for faster, cleaner deliveries.
