Products classified under HTS 2836.92.00.00
Strontium Carbonate Powder (99% Purity)
High-purity strontium carbonate (SrCO3) powder used primarily in the production of strontium chemicals and as a flux in ceramics. It falls under HTS 2836.92.00.00 as a chemically defined carbonate of strontium, explicitly listed in the 'Other' category of carbonates per Chapter 28 notes. This inorganic compound meets the criteria for classification in this heading, excluding organo-inorganic compounds.
Technical Grade Strontium Carbonate
Technical-grade SrCO3 powder for use in pyrotechnics and glass manufacturing as a strontium source. Classified under HTS 2836.92.00.00 as strontium carbonate, a specific inorganic carbonate per subheading 'Other' in carbonates. Excludes stabilized organic forms per Chapter notes.
Electronic Grade Strontium Carbonate
Ultra-high purity strontium carbonate for strontium titanate production in capacitors and electronics. HTS 2836.92.00.00 applies as a chemically defined inorganic carbonate of strontium. Doping would shift it per Chapter notes, but pure form remains here.
Pharmaceutical Grade Strontium Carbonate
GMP-certified strontium carbonate for strontium ranelate API precursor in osteoporosis drugs. Falls under HTS 2836.92.00.00 as a pure inorganic strontium carbonate, chemically defined per Chapter 28. Not organo-inorganic.
Strontium Carbonate Granules for Metallurgy
Granular SrCO3 used as desulfurizer additive in steel production. Classified in HTS 2836.92.00.00 as strontium carbonate under 'Other' carbonates; industrial form but still chemically defined.
High-Density Strontium Carbonate for Ceramics
Dense powder SrCO3 for ferroelectric ceramics and glazes. HTS 2836.92.00.00 for pure strontium carbonate, per peroxocarbonate exclusions.
ACS Reagent Strontium Carbonate
Analytical reagent grade SrCO3 for lab chemicals and standards. Under HTS 2836.92.00.00 as chemically defined strontium carbonate.
Precipitated Strontium Carbonate
Synthetic precipitated SrCO3 for specialty chemicals. HTS 2836.92.00.00 despite production method, as pure compound.
Strontium Carbonate Micronized Powder
Fine micronized SrCO3 for paints and coatings. Classified HTS 2836.92.00.00.
Strontium Bicarbonate Solution (as Carbonate)
SrCO3 equivalent in bicarbonate form for water treatment. HTS 2836.92.00.00 for carbonate base.
