NMFC 50520 - Concrete Well Casings/Tops | Class 60

To find the correct freight class for your shipment:

1. Use a rugged wood crate or heavy-duty box; add 2x4 runners under crates so forklifts can lift evenly and block each piece to prevent movement.
2. Pad contact points with foam or rubber and add edge protectors to avoid chipping; use dividers if multiple tops ship in one crate.
3. Mark center of gravity, apply Do Not Stack where needed, and keep each handling unit within carrier weight limits for safe LTL handling.
4. Include a packing list with casting type and jobsite reference, then photograph the packed crate for records and claim support.

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

• Fixed Class 60 simplifies quoting and booking—no density math, faster LTL rate comparisons.
• Non-hazardous status avoids hazmat paperwork and fees, streamlining documentation and transit.
• Crate/box packaging reduces breakage on brittle edges, lowering claims and project delay costs.
• Clear NMFC 50520 labeling minimizes reclass and rebill risk, protecting margins for utility and contractor shipments.
