NMFC 50100 - Carbon, Gum & Sludge Removers | Class 70

Note 50102: NOTE-Applies on compounds designed to remove, loosen, soften or retard the formation of carbon, gum or sludge in internal combustion engines.

To find the correct freight class for your shipment:

1. Use strong, leak-resistant boxes with sealed liners for paste or liquid removers; include absorbent pads to contain any seepage during LTL handling.
2. Record the total weight of each packed box (product plus inner packaging) since Class 70 is weight-based and not density-rated for this item.
3. Label clearly: “Cleaning Compound—Carbon/Gum/Sludge Remover, NMFC 50100, Item 50102 Note,” and keep boxes upright to prevent residue transfer.
4. Confirm the product matches NOI criteria under item 50102; if shipping in drums instead of boxes, verify carrier acceptance and match closures to prevent leaks.

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

• Predictable pricing with fixed Class 70 rating—no density calculations or re-class surprises for this NOI compound.
• Non-hazardous status avoids hazmat fees and simplifies paperwork, accelerating pickup and terminal throughput.
• Box-focused packing reduces spill risks and accessorial cleanup charges, protecting margins on maintenance chemical shipments.
• Clear NMFC alignment (50100 with item 50102 note) minimizes inspection delays and improves on-time performance for industrial and automotive service supply chains.
