Products classified under HTS 2825.90.10.00
Beryllium Oxide Powder
High-purity beryllium oxide (BeO) powder used in ceramics and electronics for its excellent thermal conductivity and electrical insulation properties. Classified under HTS 2825.90.1000 as beryllium oxide, a chemically defined inorganic metal oxide per Chapter 28 notes. It meets the criteria for inorganic bases and metal oxides not excluded by chapter notes.
Beryllia Ceramic Powder
Beryllia (BeO) powder specifically graded for high-temperature ceramic applications like substrates in aerospace components. Falls under HTS 2825.90.1000 as beryllium oxide, distinguished from finished ceramics by its raw powder state per Chapter 28 definitions. Excluded from Chapter 69 as it's not yet a shaped article.
Synthetic Beryllium Hydroxide
Precipitated beryllium hydroxide (Be(OH)2) used as an intermediate in beryllia ceramics production and metal extraction. Classified in HTS 2825.90.1000 as beryllium hydroxide, a metal hydroxide per subheading, chemically defined and not excluded by Chapter 28 notes on salts or organics.
High-Purity Beryllium Oxide for LEDs
Ultra-pure BeO powder optimized for LED substrate manufacturing due to superior heat dissipation. HTS 2825.90.1000 applies as chemically defined beryllium oxide, not a finished optical element (excluded to 9001) or doped semiconductor per chapter notes.
Beryllium Hydroxide Flakes
Flake-form beryllium hydroxide produced from beryl ore processing, used in nuclear reactor component precursors. Under HTS 2825.90.1000 for its chemical definition as metal hydroxide, pure form not mixed or excluded by Chapter 28 notes.
Calcined Beryllium Oxide Granules
Granular calcined BeO for investment casting molds in aerospace turbine blades. Classified HTS 2825.90.1000 as beryllium oxide in granular form, still chemically defined powder/granule not shaped ceramic.
Nano Beryllium Oxide Particles
Nanoscale beryllium oxide particles for advanced composites and catalysts. HTS 2825.90.1000 covers as chemically defined BeO regardless of particle size, not organo-inorganic or excluded mixtures.
