Products classified under HTS 2811.29.20.00
Selenium Dioxide Powder
Pure selenium dioxide (SeO2) in fine powder form, used primarily as a chemical reagent in laboratory settings for organic synthesis and analytical chemistry. It falls under HTS 2811.29.20.00 as an inorganic oxygen compound of the nonmetal selenium, specifically classified as selenium dioxide per the tariff schedule. This white crystalline powder is highly reactive and hygroscopic, requiring careful handling.
Selenium Dioxide 99.9% Crystals
High-purity 99.9% selenium dioxide in crystalline form for semiconductor doping and specialty chemical synthesis. Falls squarely under HTS 2811.29.20.00 as an other inorganic oxygen compound of nonmetals, meeting Chapter 28 chemical definition notes. Sublimes at 315°C, used in vapor deposition processes.
Technical Grade Selenium Dioxide
Technical grade selenium dioxide, 98% purity, supplied in bulk for industrial glass coloring and ceramic production. Classified under HTS 2811.29.20.00 as it is a chemically defined inorganic oxygen compound of selenium without organic stabilization. Commonly used to impart red hues to glassware and enamels.
ACS Reagent Selenium Dioxide
American Chemical Society (ACS) reagent grade selenium dioxide for high-precision analytical and research applications. It qualifies for HTS 2811.29.20.00 as a pure, chemically defined other inorganic oxygen compound of nonmetals (selenium). Packaged in 100g bottles with lot-specific certificates of analysis.
Industrial Selenium Dioxide Flakes
Selenium dioxide in flake form for large-scale use in pigment manufacturing and metal finishing electrolytes. Classified in HTS 2811.29.20.00 due to its identity as a chemically defined inorganic oxygen compound of selenium, excluded from other chapters per notes. Provides selenium source without halide impurities.
