How to Determine Your Class
To find the correct freight class for your shipment:
- Match one of the three NMFC subclasses by how the parts move—choose packaged for most items, and reserve loose only for oversized frames that cannot be crated.
- Protect wear surfaces on screen decks, mesh panels, and rubber media with plywood facings, corner guards, and banding; palletize to prevent flexing during LTL handling.
- For vibrator motors, drive units, and bearing housings, bolt to skids and block the shaft ends; clearly mark lift points to prevent tip-overs at terminals.
- Separate sharp steel side plates and chute liners from delicate components with dunnage; wrap dusty or oily used parts in poly to avoid contaminating other freight.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Packaging to the right subclass can lower charges within the 65–150 range, improving rate competitiveness on recurring quarry and recycling shipments.
- Non-hazmat status speeds up carrier acceptance and quoting, reducing lead times for maintenance turnarounds at plants.
- Crating and proper blocking cut claims on machined faces and rubber media, protecting uptime and avoiding costly reorders.
- Clear classification under NMFC 129600 helps prevent reclass fees and disputes, stabilizing freight budgets across project cycles.
