Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If Pre-mixed zinc dust paints classify under Chapter 32 as iron oxide or anti-corrosive pigments.
If slab zinc refined >99.99% purity
Unwrought refined zinc slabs fall under 7901, not dust forms.
If containing zinc oxide rather than metallic zinc
Zinc oxide (ZnO) is an inorganic oxide under Chapter 28, distinct from metallic zinc dust.

Import Tips & Compliance
• Include sieve analysis reports confirming 80% particles through 63-micron mesh to distinguish from powders
• Label containers with UN numbers for flammable solids (zinc dust is pyrophoric when dry)
• Check for anti-dumping duties if sourced from specific countries like China
