Chapter 79: Zinc and articles thereof
Plain-language overview
Use HS-4 7903 when importing or exporting zinc in the form of dust, powders, or flakes. For example, if you're shipping zinc dust for use in batteries, this is the relevant code to consider.
When deciding between HS-6 790310 for zinc dust and HS-6 790390 for zinc powders and flakes, consider the physical form of the zinc. Zinc dust is typically a fine powder used in coatings, while powders and flakes may be used in a wider variety of applications, including metallurgy and chemical processes.
If your shipment consists of zinc powder that is not classified as dust, you should use HS-6 790390. This line covers zinc in forms that are more granular or flake-like, which may be used in different industrial applications compared to the finer dust.
