Classification Details
| NMFC | Description | Class |
|---|---|---|
| 181330.00 | Iron or Steel, lined with aluminum, block tin, copper, nickel or nickel-copper, in boxes or crates, or loose if outer walls are steel, 7 gauge or thicker | 100 |
How to Determine Your Class
To find the correct freight class for your shipment:
- Verify packaging eligibility first: ship loose only when the outer shell is steel at least 7 gauge (about 3/16 in). Otherwise select a crate or heavy box.
- Protect the lining metal from abrasion and galvanic contact. Use rubber mats, plastic edge guards, and coated straps; cap all nozzles and cover manways.
- Block and brace on a skid or inside a crate so fittings don’t carry weight. Mark lift points and orientation (Do Not Fork Under Shell) for safer handling.
- List on the BOL: “NMFC 181330, Class 100, non-hazardous,” chosen packaging type (box/crate/loose), and the lining metal (e.g., nickel or tin) for clear identification.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Fixed Class 100 simplifies quoting and eliminates density calculations, reducing reclass and inspection fees.
- Packaging flexibility—loose allowed with 7‑gauge steel walls—can cut crating labor, materials, and lead time.
- Clear lining and packaging guidance reduces in-transit damage risk to expensive interior metals, lowering claim exposure.
- Predictable rating improves LTL network fit, speeds tendering, and supports accurate cost planning for industrial projects.
