Zinc Oxide and Zinc Peroxide

Zinc oxide is one of the most commercially versatile inorganic compounds, serving as a rubber vulcanization activator, UV-absorbing pigment in sunscreens and coatings, and a semiconductor material in electronics — all classified under a single tariff line (2817000000). Mexico and Canada are the top US import sources, benefiting from USMCA preferential duty treatment that can meaningfully reduce landed cost compared to non-preferential origins. Particle size and surface treatment (standard vs. nano-grade) are critical commercial specifications that do not create separate HTS subdivisions but are essential for end-use compliance.
