2836.20.00.00 - Disodium carbonate

HTS code 2836.20.00.00 specifically classifies Disodium carbonate, also commonly known as soda ash. This inorganic chemical compound is a salt of carbonic acid and sodium, typically appearing as a white, anhydrous crystalline powder or granular solid. It finds extensive use across numerous industrial applications, including glass manufacturing, chemical production, detergent formulation, and in the pulp and paper industry.

This classification is distinguished from its siblings by its specific chemical composition. For instance, 2836.30.00.00 covers Sodium hydrogencarbonate (baking soda), which is a distinct chemical compound with a different molecular structure and properties. Similarly, potassium carbonates (2836.40), calcium carbonate (2836.50.00.00), and barium carbonate (2836.60.00.00) are all different metallic salts of carbonic acid, each with unique chemical and physical characteristics and industrial uses that necessitate their separate classification.

As a leaf node within the HTS structure, HTS code 2836.20.00.00 does not have further subdivisions. Therefore, the focus for classification under this code is on ensuring the imported or exported product is indeed Disodium carbonate and not a related but distinct chemical compound covered by a sibling HTS code. Proper identification and verification of the chemical identity are paramount for accurate customs declaration.
