NMFC 136400 - Sodium-Potassium Alloys | Class 100

To find the correct freight class for your shipment:

1. Use sealed metal inner containers placed inside robust wooden boxes with non-reactive cushioning; mark boxes “Keep Dry” and add orientation arrows and handling labels.
2. Declare the commodity as hazardous on the BOL, attach the latest SDS, list NMFC 136400 and Class 100, and include a 24/7 emergency contact for compliance checks.
3. Pre-verify carrier hazmat acceptance for water‑reactive metals and schedule pickup with terminals that handle dangerous-when-wet materials to avoid tender refusals.
4. Palletize wooden boxes, block and brace to prevent shifting, keep freight away from liquids and oxidizers, and avoid humid storage areas during staging or cross-dock moves.

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

• Fixed Class 100 rating delivers predictable LTL pricing without density calculations, simplifying quoting and routing decisions.
• Correct metal-in-wood packaging minimizes leak or reaction risks, reducing claims, cleanup exposure, and costly service interruptions.
• Clean hazmat documentation speeds carrier acceptance, cutting recons, delays, and detention charges tied to compliance reviews.
• Carrier pre-approval and proper labeling reduce terminal handling time, improving on-time performance and strengthening service reliability.
