Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If tungsten-thorium alloys
Metal alloys go to Section XV; pure thorium remains in Chapter 28.
If carbides only, misclassified
Carbides specifically in 2849; elemental thorium separate.

Import Tips & Compliance
• Pyrophoric risk; ship under inert gas or oil per DOT special provisions
• NRC Form 741 mandatory for all thorium imports regardless of form
• Differentiate from alloys (Section XV exclusion per Chapter note)
