NMFC 133700 - Magnesium Blanks & Extrusions | Class 70

Note 133701: NOTE-Applies only on articles manufactured solely by a blanking, extruding or stamping process.

To find the correct freight class for your shipment:

1. Verify packaged density meets 15 lb/ft³ or more. Example: a 180 lb pallet occupying 10 ft³ equals 18 pcf, which qualifies for Class 70.
2. Bundle extrusions and moldings with edge guards and blocking, then overwrap or crate. Keep parts fully packaged—no loose lengths—to prevent bending and scuffing.
3. Print the BOL with “NMFC 133700, Class 70,” and list the part type (blank, extrusion, molding, stamping) and alloy. Reference NMFC Notes 133701 and 133703 to confirm NOI scope and density basis.
4. Do not mix solid parts with chips, powders, or scrap in the same package. Keep shipments clean and dry to maintain the non-hazardous, solid classification.

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

• Achieve Class 70 pricing by meeting the 15 pcf threshold, lowering LTL costs compared to lower-density packaging.
• Non-hazardous solid magnesium parts avoid hazmat surcharges and increase carrier acceptance, simplifying scheduling.
• Accurate NMFC labeling and density documentation reduce reclass and rebill risks, protecting margins and customer trust.
• Rigid, pallet-ready bundles speed dock handling and reduce damage on long extrusions or thin stampings, cutting claim exposure.
