Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pre-formulated into pyrotechnic mixture
Safety fuses or pyrotechnic articles containing zinc dust fall under Chapter 36.
If in the form of zinc bars or profiles
Wrought zinc in bar form is under Chapter 79 heading 7907, not dust.
If reaction accelerators containing organic modifiers
Chemically modified zinc dust for catalysts goes to Chapter 38.
