NMFC 50410 - Barium Sulfate X-ray Compounds | Class 55

To find the correct freight class for your shipment:

1. Confirm formulation limits: barium sulfate base with no more than 10% other ingredients; keep a spec sheet or SDS handy to show carriers if asked.
2. Package in sturdy boxes or closed-head drums with moisture barriers or poly liners to prevent caking and leakage of this dense, inert powder.
3. Rate by weight at Class 55; record net and gross weights accurately on the BOL, especially for heavy drums where pallet and packaging tare add up.
4. Palletize tightly—stretch-wrap, corner-board, and band drums or boxed pails; mark “Keep Dry” and avoid overstacking due to high unit weight.

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

• Low Class 55 keeps LTL costs down for dense mineral powder, improving margins on routine restocks for imaging and lab suppliers.
• Non-hazardous status simplifies booking and eliminates hazmat fees, widening carrier options and reducing transit delays.
• Weight-based rating delivers predictable quotes without density studies, streamlining procurement and automated rate shopping.
• Clear packaging guidance (boxes or drums) cuts claim risk, minimizing rework and protecting product integrity over long hauls.
