How to Determine Your Class

To find the correct freight class for your shipment:

  1. 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.
  2. 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.
  3. 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.
  4. 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.
