Products classified under HTS 2830.90.20.00
Cadmium Sulfide Powder
High-purity cadmium sulfide (CdS) powder used primarily as a pigment in paints, coatings, and plastics for its bright yellow color. It falls under HTS 2830.90.20.00 as a chemically defined inorganic sulfide of cadmium. This form is suitable for industrial mixing and application.
Cadmium Sulfide Pigment Grade
Cadmium sulfide in pigment-grade form, offering excellent lightfastness and opacity for high-end artists' oil paints and automotive coatings. Classified under HTS 2830.90.20.00 as other cadmium sulfide, distinct from formulated pigments. Used where vibrant, durable yellow hue is required.
High-Purity Cadmium Sulfide for Semiconductors
Ultra-high purity (6N) cadmium sulfide crystals or powder for manufacturing II-VI compound semiconductors like CdS photodetectors. Falls under HTS 2830.90.20.00 as chemically defined cadmium sulfide. Not doped or wafer-formed, qualifying for Chapter 28.
Cadmium Sulfide Luminescent Grade
Specially prepared cadmium sulfide activated for phosphorescence in glow-in-the-dark paints and safety markings. Classified as cadmium sulfide under HTS 2830.90.20.00 since not final luminophore product. Provides yellow-green afterglow effect.
Synthetic Cadmium Sulfide Crystals
Synthetic single-crystal cadmium sulfide grown for optical research and thin-film deposition in photovoltaics. Pure compound form qualifies for HTS 2830.90.20.00 as other cadmium sulfide. Size typically 1-10mm for lab use.
Cadmium Sulfide for Glass Coloring
Cadmium sulfide specifically for producing stable yellow colors in glass tableware and decorative bottles. Chemically defined powder under HTS 2830.90.20.00, added during glass melting. Heat-stable up to glass frit temperatures.
Nano Cadmium Sulfide Particles
Cadmium sulfide nanoparticles (10-50nm) for quantum dot applications in displays and biomedical imaging. Still classified as chemically defined CdS under HTS 2830.90.20.00 when >99% pure. Surface-capped but primary compound identity maintained.
Cadmium Sulfide Technical Grade Yellow
Technical-grade cadmium sulfide providing cost-effective yellow pigmentation for plastics, rubber, and ceramics. HTS 2830.90.20.00 applies to this chemically defined sulfide form before incorporation. Known for thermal stability up to 1000°C.
