Products classified under Tariff item 2836.92
ACS Reagent Strontium Carbonate
ACS reagent grade strontium carbonate (SrCO3) is a chemically defined inorganic compound of high purity, meeting the requirements of Chapter 28 Note 1(a). It is used as an analytical standard and in laboratory chemicals, and is correctly classified under tariff item 2836.92.00 as strontium carbonate.
2836.92.00Electronic Grade Strontium Carbonate
Electronic grade strontium carbonate is an ultra-high purity form of SrCO3 used as a precursor for strontium titanate in capacitors and electronics. As a chemically defined inorganic compound, it falls under tariff item 2836.92.00, provided it is not doped or otherwise modified for a specific electronic function.
2836.92.00High-Density Strontium Carbonate for Ceramics
High-density strontium carbonate powder is a dense form of SrCO3 used in ferroelectric ceramics and glazes. It is a chemically defined inorganic carbonate, and despite its physical form, it is classified under tariff item 2836.92.00 as strontium carbonate.
2836.92.00Pharmaceutical Grade Strontium Carbonate
Pharmaceutical grade strontium carbonate is a GMP-certified, chemically defined SrCO3 used as a precursor for strontium ranelate in osteoporosis medications. It is an inorganic compound of strontium, not an organo-inorganic compound, and is correctly classified under tariff item 2836.92.00.
2836.92.00Precipitated Strontium Carbonate
Precipitated strontium carbonate is a synthetic form of SrCO3 produced by precipitation, used in specialty chemicals. As a chemically defined inorganic compound, it is classified under tariff item 2836.92.00 regardless of the production method.
2836.92.00Strontium Bicarbonate Solution (as Carbonate)
Strontium bicarbonate solution, presented as a carbonate equivalent, is not a stable solid but a solution of strontium bicarbonate. Since it is a solution of a strontium compound in water, it may fall under tariff item 2836.92.00 if it meets the criteria of Chapter 28 Note 1(b) for aqueous solutions of chemically defined compounds.
2836.92.00Strontium Carbonate Granules for Metallurgy
Strontium carbonate granules for metallurgy are granular SrCO3 used as a desulfurizer additive in steel production. As a chemically defined inorganic compound in granular form, it is classified under tariff item 2836.92.00, as the physical form does not affect classification.
2836.92.00Strontium Carbonate Micronized Powder
Strontium carbonate micronized powder is a fine powder form of SrCO3 used in paints and coatings. It is a chemically defined inorganic compound, and the micronized particle size does not change its classification under tariff item 2836.92.00.
2836.92.00Strontium Carbonate Powder (99% Purity)
Strontium carbonate powder at 99% purity is a high-purity chemically defined compound used in strontium chemical production and as a flux in ceramics. It falls under tariff item 2836.92.00 as strontium carbonate, meeting the requirements of Chapter 28 for separate chemically defined compounds.
2836.92.00Technical Grade Strontium Carbonate
Technical grade strontium carbonate is a lower-purity form of SrCO3 used in pyrotechnics and glass manufacturing. As a chemically defined inorganic compound, it is classified under tariff item 2836.92.00, provided it meets the purity requirements for a separate chemical compound and is not a mixture.
