Products classified under HTS 7903.90.60.00
Zinc Dust for Rubber Vulcanization
Fine zinc dust produced by condensing zinc vapor, used as an activator in rubber vulcanization processes. It meets chapter definitions with at least 85% metallic zinc and 80% of particles passing 63-micron sieve, classifying under 7903.90.60.00 as other zinc dust.
High-Purity Zinc Dust for Paint Pigments
Spherical zinc dust from vapor condensation, ideal for anti-corrosive paint formulations due to its fine particle size (<63 microns). Classified in 7903.90.60.00 as other zinc dust per chapter note (c) definitions.
Zinc Dust for Diamond Polishing Compounds
Ultra-fine zinc dust meeting chapter note (c) specs, used as a binder in diamond polishing slurries for gemstone and industrial diamond finishing. Falls under 7903.90.60.00 as other zinc dust/powders/flakes.
Metallic Zinc Dust for Pyrotechnics
Fine spherical zinc dust from zinc vapor condensation, containing ≥85% metallic zinc, used in pyrotechnic compositions for sparks and effects. HTS 7903.90.60.00 covers this as other zinc dust.
Industrial Zinc Dust for Chemical Synthesis
High-grade zinc dust with 90%+ metallic content and fine particle distribution (<63 microns), employed as a reducing agent in organic synthesis reactions. Classified under 7903.90.60.00 per precise chapter definitions.
