NMFC 113800 – Concentrated Lye in Boxes or Drums | Cl 55

To find the correct freight class for your shipment:

1. Verify the product form via the SDS (solid flakes/pellets or solution) and apply the correct hazmat identifiers; examples include UN1823 (sodium hydroxide, solid) or UN1813 (potassium hydroxide, solid).
2. Use rugged packaging: heavy fiberboard boxes with sealed plastic liners for solids, or UN-rated poly/steel drums for liquids. Add absorbent and corrosion-resistant overpack where spill risk exists.
3. Complete hazmat documentation on the BOL: list NMFC 113800, Class 55, proper shipping name, UN ID, Class 8 CORROSIVE labels, emergency contact, and request hazmat service/accessorials.
4. Load and segregate carefully. Keep away from acids, ammonium salts, and aluminum; secure drums with banding and stretch-wrap, and keep boxes elevated on plastic pallets to prevent caustic contact.

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

• Consistent Class 55 rating helps control LTL spend versus ad hoc hazmat reclassifications.
• Accurate NMFC usage reduces billing corrections, reweigh/reclass fees, and delays tied to incomplete hazmat data.
• Carrier-ready packaging (boxes or drums) improves acceptance, speeds tendering, and avoids refused shipments.
• Lower claim exposure by preventing leaks and corrosion damage, protecting both equipment and co-loaded freight.
