NMFC 50232 - Iron/Steel Cleaning Compounds | Class 55-100

To find the correct freight class for your shipment:

1. Confirm the product is non-corrosive on the SDS, then determine if other hazmat traits apply (e.g., flammable). Include the proper shipping name and UN/NA number if required.
2. Quote and book by total handling-unit weight. Classes are weight-based for this item, so verify gross weight per drum, pail, or tote to hit the correct bracket.
3. Use tight, leak-resistant, UN-rated containers with secure closures. Palletize upright, add absorbent and a liner if needed, and apply orientation and hazmat labels clearly.
4. Separate these cleaners from food items and incompatible chemicals. Provide carriers with SDS and hazmat paperwork to avoid pickup refusals and delays.

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

• Accurate weight-bracket classing (55–100) reduces reclass and rebill risk, protecting margins on repeat LTL moves.
• Potential to consolidate into heavier handling units to qualify for lower classes, cutting linehaul costs when operationally feasible.
• Proper hazmat documentation and packaging speed carrier acceptance, reducing dwell time and accessorials tied to failed pickups.
• Non-corrosive designation expands carrier options versus corrosives while still maintaining safety compliance for hazardous traits.
