NMFC 176410 - Silicon Carbide in Lined Drums | Class 55

To find the correct freight class for your shipment:

1. List the commodity as “Silicon Carbide, NOI, not flour nor grain, in lined drums” on the BOL and apply Class 55; no density break is needed.
2. Palletize drums with drum rings secured, add top/bottom boards, and stretch-wrap to prevent abrasive movement and lid creep during transit.
3. Keep drums dry and upright; check liners for integrity before shipping to avoid contamination or leakage of fine granules.
4. Use drum grippers or clamps for loading, and place away from fragile freight; note “Non-Hazmat Abrasive” for quick carrier acceptance.

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

• Fixed Class 55 rating simplifies rating and reduces reclass risk, helping prevent surprise adjustments and dispute costs.
• Non-hazardous status streamlines carrier selection and avoids hazmat surcharges, improving landed cost on LTL lanes.
• Lined drum packaging lowers contamination and abrasion-related claims, protecting both product integrity and equipment.
• Clear NMFC mapping accelerates quoting and tendering, shortening cycle times from rate request to pickup confirmation.
