Products classified under Tariff item 28.17
Active Zinc Oxide for Rubber Tires
High-activity zinc oxide powder with a surface area of 50-60 m²/g, used as a vulcanization activator in rubber tire compounds. This chemically defined zinc oxide meets Chapter 28 Note 1 criteria and is classified under tariff item 2817.00.00.
2817.00.00Battery Grade Zinc Oxide Powder
Ultra-high purity zinc oxide (99.99%) in powder form for zinc-air battery cathodes and alkaline battery production. As a separate chemically defined compound, it is correctly classified under tariff item 2817.00.00.
2817.00.00Industrial Zinc Oxide 99.5% Pure
Industrial zinc oxide powder at 99.5% purity, used as a key activator in rubber vulcanization and tire manufacturing. This chemically defined inorganic compound falls squarely under tariff item 2817.00.00.
2817.00.00Medical Grade Zinc Oxide Non-Nano
Medical grade zinc oxide with non-nano particles (>100 nm) for barrier creams and antimicrobial wound dressings. As a pure chemically defined compound, it is classified under tariff item 2817.00.00, not as a pharmaceutical preparation.
2817.00.00Nanoparticle Zinc Oxide for Cosmetics
Nanoparticle zinc oxide (20-30 nm) for UV protection in sunscreens and cosmetics. Despite the small particle size, it remains a chemically defined zinc oxide and is classified under tariff item 2817.00.00 per Chapter 28 notes.
2817.00.00Pharmaceutical Zinc Oxide Ointment Base
Sterile zinc oxide powder prepared as a base for diaper rash ointments and calamine lotion. As a pure chemically defined compound, it remains under tariff item 2817.00.00 even when intended for pharmaceutical use.
2817.00.00Transparent Zinc Oxide for Clear Coatings
High-purity, coated transparent zinc oxide nanoparticles for UV protection in clear coatings and automotive finishes. The underlying zinc oxide compound is classified under tariff item 2817.00.00, provided the coating does not render it a prepared additive.
2817.00.00Zinc Calamine Powder IP Grade
IP-grade calamine powder consisting primarily of zinc oxide with trace ferric oxide for pharmaceutical skin treatments. Although it contains a small impurity, it still qualifies as zinc oxide under tariff item 2817.00.00 if the ferric oxide is incidental.
2817.00.00Zinc Oxide Catalyst Support Precursor
High surface area zinc oxide used as a precursor for catalyst supports in petrochemical reforming. As a chemically defined zinc oxide, it is classified under tariff item 2817.00.00 before any catalyst formulation.
2817.00.00Zinc Oxide Dispersion 50% in Water
A 50% aqueous dispersion of nano zinc oxide for easy incorporation into coatings and textiles. Since the water is a normal and necessary method of putting up for transport, the zinc oxide remains classified under tariff item 2817.00.00.
2817.00.00Zinc Oxide for Ceramic Glazes
Calcined zinc oxide powder for fluxing and opacifying effects in ceramic glazes and enamels. This pure inorganic metal oxide is classified under tariff item 2817.00.00, regardless of its intended use.
2817.00.00Zinc Oxide for Feed Grade Animal Nutrition
Feed-grade zinc oxide (ZnO 72-78%) providing essential trace mineral for livestock supplements. As an inorganic zinc compound not covered by Chapter 31, it is classified under tariff item 2817.00.00.
2817.00.00Zinc Oxide French Process White Seal
Premium French process zinc oxide (White Seal grade) for paints, coatings, and ceramics, produced via vapor oxidation. This pure zinc oxide is classified under tariff item 2817.00.00.
2817.00.00Zinc Oxide Powder USP Grade
Pharmaceutical-grade zinc oxide powder meeting USP standards, used in ointments and creams for wound healing and skin protection. As a chemically defined inorganic compound, it is classified under tariff item 2817.00.00.
2817.00.00Zinc Peroxide Technical Grade
Technical-grade zinc peroxide used as a bleaching agent and oxidant in chemical processes. Tariff item 2817.00.00 explicitly covers both zinc oxide and zinc peroxide as inorganic compounds.
