NMFC 50217 - Hot Topping Compounds | Class 55

Note 50218: NOTE-Applies only on compounds to be applied to the surface of molten metal in ingots or molds to prolong the molten condition and reduce shrinkage and cavities.

To find the correct freight class for your shipment:

1. Verify the product qualifies under Note, item 50218, then list the BOL as “Compounds, hot topping, NMFC 50217, Class 55” to prevent reclass and inspections.
2. Choose packaging that resists moisture: poly-lined bags, double-wall boxes, or tight-head drums. Example: 40x48 pallet with 50‑lb bags, stretch‑wrapped with a top sheet.
3. Weigh accurately on a calibrated scale and include pallet weight. This item is weight-rated, so no density calculation or dimensions are required for classing.
4. Control dust and spillage: seal liners, use corner boards, keep drums upright with rings secured, and mark pallets “Do Not Break Down” when unitized.

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

• Fixed Class 55 rating streamlines quoting and reduces reclass risk, helping avoid unexpected inspection fees.
• Flexibility to ship in bags, boxes, or drums lowers repack costs and shortens dock time across mixed facilities.
• Non-hazardous status eliminates hazmat surcharges and extra documentation, improving transit speed and budget reliability.
• Weight-only classification accelerates rate shopping and provides predictable LTL cost modeling across lanes and seasons.
