How to Determine Your Class
To find the correct freight class for your shipment:
- Specify if you’re shipping full frames or sectional components, and list attachments like pottery insulators, copper tubing, or switch parts on the BOL to align with class 100-150.
- Keep each unit securely on robust skids sized to the base footprint; add cross-bracing, steel banding, and blocking to stop racking during forklift or crane handling.
- Shield brittle insulators with foam-lined crates or vibration-damping mounts, and cap all tubing ends; mark any overhangs and protect contact points with edge guards.
- Confirm site equipment before pickup: forklift capacity, lift points, and boom reach; request a flatbed with tarps or a Conestoga if weather protection is needed.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Correct use of NMFC 179730 minimizes reclassification fees and disputes, protecting margins on high-value utility builds and upgrades.
- Skid-mounted sections speed loading and unloading, reducing dwell time and curbing accessorials tied to extended handling or carrier wait time.
- Enhanced protection for insulators and switch parts cuts claim risk and avoids costly delays when commissioning new yards or expansions.
- Non-hazardous status streamlines paperwork and supports competitive pricing across the variable 100-150 class range.
