NMFC 57520 - Roasted Dolomite in Bags/Drums | Class 50

To find the correct freight class for your shipment:

1. State on the BOL: “Roasted refractory dolomite, granular, NMFC 57520, Class 50,” and list total weight, bag/drum count, and pallet quantity for quick rating.
2. Use heavy-duty pallets and stretch wrap with a top sheet; add corner boards for stacked bag loads to prevent abrasion and burst at forklift entry points.
3. For drums, band to pallets with two cross straps and one girth strap; verify bungs/lids are secure and apply drum cones if double-stacking.
4. Control dust and moisture: select sewn or heat-sealed bags with liners, or lined fiber/steel drums, and cover pallets with waterproof caps for outdoor transfers.

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

• Locked-in Class 50 eliminates density disputes, reducing reclass fees and quote variance on dense mineral shipments.
• Non-hazardous status speeds tendering and avoids hazmat surcharges or special handling delays.
• Clear commodity naming (roasted, clinkered, dead-burned) improves carrier acceptance and minimizes inspection holds.
• Stronger packaging and palletization cut spill risks, lowering cleanup costs and preventing claim deductions for contamination.
