Products classified under HTS 2825.50.20.00
Cuprous Oxide Red Pigment Powder
High-purity cuprous oxide (Cu2O) in fine red powder form, used primarily as a pigment in paints, coatings, and antifouling marine paints. It falls under HTS 2825.50.20.00 as it is chemically defined cuprous oxide, a copper oxide classified in Chapter 28 for inorganic metal oxides.
Technical Grade Cuprous Oxide for Antifouling Paints
Technical-grade cuprous oxide powder (Cu2O) with 97% minimum purity, specifically formulated for use in marine antifouling paints to prevent biofouling on ship hulls. Classified under HTS 2825.50.20.00 as pure cuprous oxide, a copper(I) oxide meeting Chapter 28 definitions for metal oxides.
Cuprous Oxide Micronized Powder for Ceramics
Micronized cuprous oxide (Cu2O) particles with average size under 5 microns, used as a colorant in ceramic glazes to produce red hues. It is classified under HTS 2825.50.20.00 as a chemically defined copper oxide, distinct from finished ceramic products.
Pharmaceutical Grade Cuprous Oxide USP
Ultra-pure cuprous oxide (Cu2O) meeting USP standards for use in pharmaceutical and nutraceutical applications as a trace mineral source. Falls under HTS 2825.50.20.00 as a chemically defined inorganic copper oxide, not an organic compound.
Cuprous Oxide Catalyst Precursor
Synthetic cuprous oxide powder used as a precursor in manufacturing copper-based catalysts for organic synthesis reactions. Classified under HTS 2825.50.20.00 as a pure metal oxide, prior to activation or support.
Battery Grade Cuprous Oxide Nanoparticles
Nano-scale cuprous oxide (Cu2O) particles (20-50 nm) for lithium-ion battery electrode materials and supercapacitors. It is a chemically defined copper oxide under HTS 2825.50.20.00, classified by composition regardless of particle size.
Cuprous Oxide Agricultural Fungicide Active
Technical cuprous oxide powder serving as the active ingredient in copper-based fungicides for crop protection. Classified under HTS 2825.50.20.00 as bulk metal oxide, not a formulated pesticide product.
