NMFC 51100 - Oil Tank Fill Caps & Pipes | Class 50

To find the correct freight class for your shipment:

1. Pack together to match the listing: place fill caps and their corresponding pipes in the same heavy-duty box or wood crate, then secure to a pallet for LTL pickup.
2. Protect threads and sealing faces: use plastic thread protectors or pipe plugs, wrap caps with VCI paper, and add divider boards to prevent metal-on-metal contact.
3. Immobilize the load: chock round pipes, add cross-bracing inside crates, and strap cartons so pieces cannot roll or shift during terminal handling.
4. Bill correctly: list as “Fill Caps and Pipes, Oil Tank — NMFC 51100 — Class 50 — Non-Hazardous — Box/Crate” and include piece counts and approximate lengths.

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

• Low, fixed Class 50 keeps LTL base rates sharp for dense, durable metal tank hardware.
• Single combined listing reduces reclass risk and billing disputes versus rating caps and pipes separately.
• No density requirement streamlines quoting and eliminates surprise reweigh/reclass fees.
• Boxed or crated units stack cleanly, improving trailer cube and lowering the chance of linear-foot charges.
