NMFC 106900 - Slabs, in the rough | Class 50

Note 106902: NOTE-Applies on raw or unfinished material, rough rolled or rough hot-cast and not smooth nor surface finished, to be reheated for purpose of rerolling, forging, hammering or piercing, which may be transported on open trucks without damage from weather and which is of following dimensions: Slabs 1 1/2 inches or over thick, the combined width of the 4 sides of each being 14 inches or over.

To find the correct freight class for your shipment:

1. Verify the product fits Note 106902: unmachined, mill slabs of iron or steel. If pieces are finished plate or precision cut, use the correct alternate NMFC.
2. Enter NMFC 106900, Class 50 on the BOL. List the number of slabs per bundle, total bundle weight, and a plain description like “steel slabs – rough” to reduce inspection questions.
3. Package for forklift clearance and restraint: stage slabs on 4x4 hardwood dunnage, add cross dunnage between layers, apply steel banding with edge protectors, and keep all pieces flush with the skid (no overhang).
4. Match mode to handling weight: LTL works when each unit is within dock equipment limits (often ≤ 3,500–4,000 lb). Heavier, long, or multibundle moves load better on flatbed with blocking, chocks, and chain tie-downs.

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

• Class 50 rating on dense steel slabs typically delivers lower LTL tariffs versus higher classes, trimming linehaul costs on heavy mill freight.
• No density calculation needed for rating, which speeds quoting and helps prevent reclass bills for minor spec variances.
• Proper bundling on skids consolidates handling units, reducing minimum charges, damage risk, and time at pickup and delivery docks.
• Clear compliance with Note 106902 and accurate BOL details cut the risk of carrier inspections, reweigh/reclass fees, and delivery delays.
