NMFC 50385 - Dry Rust/Scale Compounds | Class 70

To find the correct freight class for your shipment:

1. Use sturdy corrugated boxes with a moisture barrier (poly-lined bags or sealed inner liners) to keep the dry compound from clumping and leaking.
2. Record actual scale weight per box and include pallet weight; NMFC 50385 is weight-based, so precise weights prevent reclass and balance billing.
3. Apply required hazmat marks and shipping names per SDS, and keep copies accessible to drivers and terminals; segregate from foodstuffs and incompatible oxidizers/acids.
4. Palletize tightly with stretch wrap and corner boards; add “Keep Dry” and orientation arrows to reduce handling damage for powdery contents.

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