Alternative Classifications

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

2845.10.00.00Same rate: 37.5%

If containing only deuterium and oxygen

Heavy water of specific deuterium oxide composition gets precise subheading 2845.10, distinct from general 'other' compounds.

2853.90Lower: 15.3% vs 37.5%

If classified as other inorganic hydrogen compound

Some hydrogen isotope compounds without specific provision may fall under broader 2853 if not chemically defined isotopes.
