NMFC 104770 - Iron/Steel Castings & Forgings | Class 50

Note 104771: NOTE-Applies only on articles manufactured solely by a casting or forging process.

To find the correct freight class for your shipment:

1. Confirm density meets or exceeds 50 lb/ft³ by dividing total shipment weight by cubic feet; e.g., 145 lb ÷ 2.5 ft³ = 58 lb/ft³ qualifies for Class 50.
2. Use true “packages” to comply: palletized and banded bundles, crated parts, or boxed castings. Loose or unbanded pieces may not qualify under this item.
3. Reference notes 104771 and 104773 for item-specific rules, especially when mixing sizes or bundling irregular shapes common with foundry or machine shop shipments.
4. Protect surfaces and edges with blocking, corner guards, and moisture barriers; mark center of gravity and forklift pockets to prevent damage and reclass fees.

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

• Achieve low Class 50 pricing when density is ≥50 pcf, often delivering significant LTL cost savings on heavy, compact metal parts.
• Reduce reweigh/reclass disputes by documenting density and packaging method on the BOL, improving billing accuracy and cycle time.
• Standard packaged presentation (crates, skids, banded bundles) speeds cross-dock handling, minimizing damage risk and OS&D claims for high-mass items.
• Non-hazardous classification simplifies carrier acceptance and avoids hazmat surcharges, streamlining quoting and tendering.
