Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other metal carbonates
If blended with other inorganic carbonates, it may classify under the more specific other carbonates subheading.
If industrial mixtures
Additives for specific uses (e.g., water softeners) make it a preparation under 3824.
If phosphatic impurities
Presence of phosphates could reclassify under Chapter 28 phosphates.

Import Tips & Compliance
• Certify minimum purity via COA to distinguish from lower-grade mixtures; declare bulk density accurately for freight classing
• Avoid packaging that implies retail sale to prevent 3824 shift

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.
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
