Overview
This HTS category, 2836.30.00.00, specifically classifies sodium hydrogencarbonate, commonly known as sodium bicarbonate or baking soda. This substance is an inorganic chemical compound characterized by its mild alkalinity and its ability to act as a leavening agent in baking, a cleaning agent, and an antacid. It is typically a white, crystalline powder and is distinct from other carbonates due to its chemical formula and properties.
Within the broader category of "Carbonates; peroxocarbonates (percarbonates); commercial ammonium carbonate containing ammonium carbamate," this heading is differentiated from its siblings by the specific cation. While disodium carbonate (2836.20.00.00) also involves sodium and carbonate, sodium hydrogencarbonate possesses an additional hydrogen atom in its structure, significantly altering its chemical behavior and applications. Similarly, it differs from potassium carbonates (2836.40), calcium carbonate (2836.50.00.00), and barium carbonate (2836.60.00.00) by the presence of sodium and its specific bicarbonate form.
As a leaf node, there are no further subcategories under 2836.30.00.00. Therefore, classification within this heading relies on accurately identifying the product as sodium hydrogencarbonate, often confirmed by chemical analysis or product specifications. Its primary uses in the food industry, pharmaceuticals, and for industrial cleaning purposes are key identifiers for correct classification.
