China customs reports HS 282590 at the 8-digit level. 10 subheadings are published under it, and export values for each are available on request.
Tungstic acid, an inorganic compound of tungsten, serves as a precursor or intermediate in specialized chemical synthesis and industrial manufacturing processes.
Tungsten trioxide, a specific oxide of tungsten in its highest oxidation state, is primarily utilized in metallurgy and the production of specialized alloys.
Tungsten oxides and hydroxides excluding tungstic acid and trioxide fulfill niche roles in chemical manufacturing and industrial processing applications.
Bismuth trioxide, a distinct bismuth compound, functions as a catalyst or additive in chemical manufacturing, glass production, and metallurgical operations.
Bismuth oxides and hydroxides other than the trioxide variant support specialized industrial processing and chemical formulation requirements.
Tin dioxide, an oxide of tin, is commonly applied in ceramic glazing, catalyst manufacturing, and specialized metallurgical processing.
Tin oxides and hydroxides not classified under specific tariff headings serve as specialized intermediates in electroplating, ceramic glazing, and catalyst production.
Niobium in its monoxide form provides distinct electrical conductivity and refractory characteristics suited for thin-film electronics and advanced metallurgical alloys.
Higher-valence niobium oxides and hydroxides function primarily as optical glass additives, dielectric ceramics, and precursor compounds for chemical vapor deposition.
Remaining inorganic bases and metal oxides, hydroxides, or peroxides without dedicated subheadings supply niche reagents for specialized industrial synthesis and surface…
