NMFC 50115 - Case Hardening & Carburizing | Class 50–70

To find the correct freight class for your shipment:

1. Verify NMFC 50115 on your BOL and select the correct class by shipment weight—no density needed. Example: a 2,000 lb pallet may rate lower (Class 50) than a 150 lb carton (Class 70).
2. Package materials in robust boxes or drums as allowed by the listing. For powders or salts, use sealed inner bags with liners, then place in UN-rated fiberboard boxes or steel drums to prevent leaks and moisture ingress.
3. Complete hazmat documentation: proper shipping name, UN/NA number, hazard class/division, packing group, and emergency contact. Attach the SDS and mark packages with required HAZMAT labels and orientation arrows.
4. Palletize tightly with stretch wrap and corner protection, keeping labels visible. Mark Keep Dry and segregate from foodstuffs; this helps heat-treaters and machine shops avoid carrier refusals and delays.

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

• Weight-based rating (Class 50–70) avoids density disputes, reducing reclass fees and unexpected add-ons.
• Strategic packaging—consolidating into heavier drums or well-braced boxes—can push shipments into lower classes and unlock better LTL rates.
• Accurate HAZMAT paperwork and NMFC 50115 usage speed carrier acceptance, shortening tender-to-pickup times.
• Compliant containment and moisture protection cut spill risks and claims, preserving product integrity and lowering total landed cost.
