NMFC 135380: Metallic Arsenic in Boxes | Class 100

To find the correct freight class for your shipment:

1. List NMFC 135380 and Class 100 on the BOL; this is a fixed class with no density calculation required.
2. Declare hazmat properly: use the SDS to identify the correct UN/NA ID and proper shipping name, and apply required marks and labels on each box.
3. Package solids in sealed inner liners (poly bags) inside rigid, durable boxes; keep contents dry, fill voids, and secure lids to prevent release of toxic dust.
4. Palletize tightly with strapping and corner protection; segregate from foodstuffs and reactive chemicals, and schedule pickup with a hazmat-authorized LTL carrier.

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

• Fixed Class 100 enables predictable rating and cleaner freight quotes, reducing reclass and dispute risk.
• Strong hazmat compliance lowers fines, terminal rejections, and claims tied to toxic exposure or contamination.
• Box-specific packing aligned to the NMFC line minimizes accessorials like reweigh/reclass and speeds dock handling.
• Using hazmat-certified carriers streamlines tendering, improves on-time performance, and stabilizes surcharge negotiations.
