NMFC 122000 - Road Grading Attachments | Class by Density

Note 122001: NOTE-Applies on blades or cutting edges with or without permanently affixed mounting brackets.

To find the correct freight class for your shipment:

1. Confirm the item subtype on the BOL (e.g., steel grader blades, scarifier drums without teeth, box blades) and note packaging as boxes or packages to align with NMFC 122000 wording.
2. Record actual weight and exterior cube per package to determine pounds per cubic foot; example: 180 lb in a 4.0 cu ft box = 45 pcf for density-based classing.
3. Guard sharp edges with blade covers and banding blocks, then brace inside the box/package to prevent shifting that can trigger damage claims or reweighs.
4. Bundle small iron/steel parts tightly to improve density and reduce class; list each component type (teeth, shanks, rakes) on the paperwork for clean inspections.

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

• Accurate density entries prevent reclass and reweigh fees, protecting margins on heavy steel parts like grader edges and scarifier shanks.
• Edge protection and tight packaging cut damage risk on expensive wear components, reducing claim costs and downtime for road crews.
• Density-optimized packing (fewer air gaps, right-size boxes) often lowers freight class, delivering better LTL rates for machinery group freight.
• Clear NMFC 122000 descriptions speed carrier approvals and quoting cycles, enabling faster dispatch for time-sensitive road projects.
