NMFC 50240 - Metal Annealing Compounds | Class 70

Note 50241: NOTE-Does not apply on materials regulated by the U.S. Department of Transportation as hazardous and required to bear a Hazard Class or Hazard Division label or placard. For classes applicable to such hazardous materials, see provisions elsewhere in this Classification.

To find the correct freight class for your shipment:

1. Package compounds in sturdy boxes with sealed liners to stop seepage; close with filament tape and label each box with NMFC 50240 and Class 70.
2. Weigh every box and record net and gross weight on the BOL; class is fixed at 70, so no density calc or dimensional breaks are needed.
3. State the material purpose clearly (metal annealing or tempering, NOI) to avoid reclassification; reference Note, item 50241, if the carrier requests details.
4. Unitize boxes on pallets with edge protection and stretch wrap; keep lids upward and add absorbent pads under cartons if formulas are oily.

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

• Non-hazardous status avoids hazmat fees and placard delays, reducing total landed cost.
• Fixed Class 70 streamlines quoting and auditing, minimizing reclass charges from density disputes.
• Standard boxed packaging speeds dock handling and improves stacking, cutting accessorials linked to repack or leaks.
• Clear NOI identification for annealing/tempering compounds keeps compliance tight and claim risk low during LTL moves.
