NMFC 133680 - Mg articles in boxes/crates | Class 150

To find the correct freight class for your shipment:

1. List the item as “Magnesium metal or alloy articles, NOI” and cite NMFC 133680 Class 150 on the BOL to prevent reclass disputes.
2. Use rigid boxes or wood crates with blocking to immobilize extrusions, billets, cast housings, or plate so pieces can’t rub and create fines.
3. Add separators or corner guards between soft Mg surfaces and fasten bundles with non-abrasive strapping; avoid loose fill that allows shifting.
4. Keep to solid articles only—no powders or turnings—and line packaging to limit moisture intrusion that could stain or corrode magnesium.

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

• Predictable Class 150 rating speeds quotes and reduces surprise reclass or inspection fees on magnesium shapes and castings.
• Non-hazardous status avoids hazmat surcharges and paperwork, cutting total landed cost for LTL moves.
• Crated or boxed packaging reduces nicking and OS&D claims on soft Mg alloys, protecting margins and customer satisfaction.
• Clear NMFC identification streamlines carrier acceptance, improving pickup reliability and on-time performance.
