NMFC 192220 - Tank Truck Manhole Parts | Class N/A

To find the correct freight class for your shipment:

1. Use double‑wall cartons with foam or corrugated inserts to shield sealing faces on covers and locking/fastening rings; bag small hardware and mark the box with cover diameter and collar type.
2. Palletize multiple boxes in a tight footprint (e.g., four 18" covers on a 48x40), add a plywood top sheet, and strap with PET banding to prevent bending of mounting collars during cross‑dock handling.
3. Describe on the BOL as “Tank truck/trailer manhole parts, boxed” and list piece count and components (covers, collars, locking rings) to avoid misclassification with concrete manholes or hazardous fuel system items.
4. If shipping with gaskets, vents, or flame arrestors, pack them separately from metal covers to prevent compression damage and include orientation or torque notes for receiving maintenance crews.

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

• Protecting machined sealing surfaces cuts claim risk and field rework for fuel haulers and tank‑wash facilities.
• Non‑hazardous parts avoid hazmat fees and carrier restrictions, expanding options and lowering LTL rates.
• Clear NMFC reference minimizes reclass bills and inspection delays, speeding terminal throughput and delivery ETAs.
• Boxed, pallet‑friendly cartons improve cubic efficiency, enabling better consolidation and cost‑per‑unit shipped.
