How to Determine Your Class
To find the correct freight class for your shipment:
- Pack blocks and sheaves so moving parts cannot rotate; use zip ties or locking pins, then cushion inside cartons or wooden crates to prevent gouging.
- Use edge-protected steel banding to secure heavy steel or cast-iron blocks to a pallet; add blocking so hooks, shackles, or fairlead rollers cannot shift.
- Bag grease-lubricated sheaves and cap rope grooves to stop oil stains and protect machined surfaces; label “Machinery Parts – NMFC 127300, Class 60.”
- For mixed shipments, bundle multiple small tackle blocks in inner boxes and place in one master carton to meet “in packages” language and cut handling touches.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Predictable Class 60 rating keeps quotes consistent across lanes and reduces reclass fees.
- Lower class versus bulky hardware often drops LTL spend 5–15%, especially when palletized efficiently.
- Proper packaging minimizes damage to precision grooves and swivels, reducing claims and downtime on rigging jobs.
- Clear NMFC mapping speeds carrier approvals and TMS routing, accelerating dock-to-dock lead times.
