Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

8101.10.00.00Higher: 32% vs 15.5%

If tungsten-thorium alloys

Metal alloys go to Section XV; pure thorium remains in Chapter 28.

2849.90.50.00Higher: 38.7% vs 15.5%

If carbides only, misclassified

Carbides specifically in 2849; elemental thorium separate.
