How to Determine Your Class
To find the correct freight class for your shipment:
- Palletize with cribbing and corner protection; block and band sections to prevent roll and edge impact. Mark Do Not Double Stack for brittle clay or terra cotta.
- Cradle long or multi‑cell pieces on custom wood skids or pipe racks; use wide straps over cradle points and never tighten straps across cell edges or bells.
- Cap or pad conduit ends and connection bells to avoid chipping. For multi‑cell ducts, fill voids with foam or corrugated pads to resist side pressure.
- On the BOL, list NMFC 50570 and note material (cement, clay, concrete, or terra cotta) plus configuration (single/multi‑cell, lined/unlined) for clear handling instructions.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Fixed Class 60 provides predictable LTL rates and simpler quoting versus density‑based items, helping avoid surprise reclass charges.
- Single NMFC for multiple materials (cement, clay, concrete, terra cotta) streamlines documentation when shipping mixed conduit and fittings on one pallet.
- Accurate use of NMFC 50570 differentiates from PVC/metal conduit, reducing inspection disputes and chargebacks tied to misclassification.
- Clear handling notes for brittle earthen goods lower breakage risk, cutting replacement costs and jobsite delays for utility trench and duct bank projects.
