Products classified under HTS 2836.20.00.00
Anhydrous Soda Ash (Disodium Carbonate)
Anhydrous soda ash is a pure form of disodium carbonate (Na2CO3) used primarily in the glass manufacturing industry as a flux to lower melting temperatures. It falls under HTS 2836.20.00.00 as it is explicitly classified as disodium carbonate, a key inorganic compound in Chapter 28 for carbonates of inorganic bases.
Dense Soda Ash (Light Soda Ash Alternative)
Dense soda ash is a high-density granular form of disodium carbonate produced via the Solvay process, ideal for detergent and chemical synthesis applications. Classified under HTS 2836.20.00.00 due to its chemical identity as Na2CO3, distinct from other carbonate salts.
Sodium Carbonate Monohydrate (Crystal Soda)
Sodium carbonate monohydrate (Na2CO3·H2O) is a crystalline hydrated form of disodium carbonate used in water treatment and as a pH buffer. It qualifies for HTS 2836.20.00.00 as chemically defined disodium carbonate, including common hydrates.
Technical Grade Soda Ash 99.2%
Technical grade soda ash with 99.2% Na2CO3 purity is used in paper manufacturing and effluent treatment as a cost-effective alkali source. Falls under HTS 2836.20.00.00 for its chemically defined disodium carbonate composition.
USP Grade Disodium Carbonate Anhydrous
USP grade disodium carbonate meets pharmaceutical standards for use in buffering solutions and as an excipient in tablets. Classified in HTS 2836.20.00.00 as pure disodium carbonate, regardless of end-use purity specs.
Calcined Soda Ash for Glass Production
Calcined soda ash is thermally processed disodium carbonate optimized for flat glass and container glass fluxing. It is imported under HTS 2836.20.00.00 as chemically defined Na2CO3, excluding organic-stabilized variants.
Granular Disodium Carbonate 99.5% Purity
Granular disodium carbonate at 99.5% purity serves as a cleaning agent in industrial boilers and textile processing. HTS 2836.20.00.00 applies to this form as pure Na2CO3, not mixtures.
Trona-Derived Synthetic Soda Ash
Trona-derived synthetic soda ash is processed from natural trona ore into disodium carbonate for soap and paper industries. Classified under HTS 2836.20.00.00 post-processing as chemically defined Na2CO3.
