NMFC 186660 - Working Tools for Power Tools | Class 50

Note 186662: NOTE-Applies only on tools consisting of one piece of forged steel, machined or not machined, designed for breaking, cutting, digging, drilling or tamping of earth or paving, or breaking or destruction of concrete or building, paving or other materials.

To find the correct freight class for your shipment:

1. Verify the items qualify: working tools and attachments for electric, pneumatic, or engine-driven tools (e.g., drill bits, saw blades, cutters, collets). If unsure, review Note item 186662 to confirm scope.
2. Package in sturdy boxes with dividers or tubes; cap sharp edges on blades and reamers; bag oily or abrasive parts to prevent residue transfer; add anti-rust wraps for high-carbon or carbide components.
3. On the BOL, write “NMFC 186660 – Tools, working, in packages, Class 50.” List package count and a clear part description (e.g., “12 carbides cutters, boxed”) to avoid reclass or inspection delays.
4. Use compact, damage-resistant cartons so dense metal tools don’t break through; add interior dunnage for weight concentration. Provide weights and dimensions for rating even though class is fixed.

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

• Predictable pricing: fixed Class 50 benefits dense metal tools and minimizes surprises from density-based reclassifications.
• Lower risk and simpler compliance: non-hazardous status and packaged requirement streamline carrier acceptance and reduce accessorials.
• Fewer claims: edge guards, tubes, and partitions protect cutting faces and threads, cutting damage costs and customer returns.
• Operational efficiency for OEMs, distributors, and MRO suppliers: a clear NMFC path speeds quotes, supports contract rates, and standardizes BOLs across lanes.
