Zinc dust, powders and flakes
3 declarable lines
Heading 7903 covers metallic zinc in dust, powder, and flake form. Zinc dust is a separate line at 7903.10.00.00, while other zinc powders and flakes fall under 7903.90. The 7903.90 breakouts separate powders at 7903.90.30.00 from other forms at 7903.90.60.00.
Products in this heading
- Zinc dust for galvanizing and anti-corrosion coatings
- Zinc powder for batteries and electrochemical cells
- Zinc flakes for protective paints and coatings
- Zinc dust for chemical reduction and synthesis
- Zinc powder for powder metallurgy and sintering
- Zinc flakes for pigment and specialty coating uses
- Zinc dust for pyrotechnic and specialty applications
How to choose the right subheading
- Confirm the article is metallic zinc in dust, powder, or flake form, not a zinc compound or unwrought zinc.
- Place zinc dust in 7903.10.00.00 and other zinc powders or flakes in 7903.90.
- Within 7903.90, use 7903.90.30.00 for powders other than dust and 7903.90.60.00 for flakes and other residual forms.
- Check the actual particle form and presentation because dust, powder, and flake are treated as different commercial forms.
- Verify metal content and any alloying before choosing the line; do not use this heading for zinc oxide or zinc scrap.
Often confused with
- Heading 7901Zinc ingots and unwrought zinc blocks
Unwrought zinc is classified in heading 7901, not as dust or powder.
- Zinc waste and scrap
Zinc scrap is classified in heading 7902, not as powder.
- Zinc bars, rods, profiles, and wire
Solid wrought zinc products are in heading 7904.
- Zinc plates, sheets, strip, and foil
Flat-rolled zinc products are in heading 7905.
- Zinc oxide powder
Zinc oxide is a chemical compound, not metallic zinc powder.
