Products classified under HTS 2836.99.50
Sodium Per Carbonate
Sodium percarbonate is a white, crystalline powder used as an oxygen bleach and disinfectant in laundry detergents and cleaning products. It falls under HTS 2836.99.50 as a peroxocarbonate (percarbonate) of an inorganic base (sodium), distinct from carbonates in other subheadings. When dissolved in water, it releases hydrogen peroxide and sodium carbonate for effective stain removal.
Lithium Carbonate Anhydrous
Anhydrous lithium carbonate is a fine white powder used in lithium-ion battery production, glass ceramics, and pharmaceuticals. Classified under HTS 2836.99.50 as 'other' carbonates of inorganic bases (lithium), excluding specific ones like calcium or sodium. It provides the lithium source for high-performance materials.
Magnesium Per Carbonate
Magnesium percarbonate is utilized in oral care products like toothpaste for whitening and as a mild disinfectant. Classified in HTS 2836.99.50 as other peroxocarbonates, per Chapter notes excluding section V products. It decomposes to hydrogen peroxide and magnesium carbonate.
Commercial Ammonium Bicarbonate
Commercial ammonium bicarbonate is a leavening agent in baked goods, decomposing to ammonia, CO2, and water. Though related to heading description, 'other' variants without carbamate fall here under HTS 2836.99.50. Widely used in cookies and crackers.
Cesium Carbonate
Cesium carbonate acts as a base catalyst in organic synthesis and glass manufacturing for low-melting formulations. HTS 2836.99.50 covers this as other carbonate of inorganic base (cesium). Hygroscopic powder essential for advanced materials.
Calcium Per Carbonate
Calcium percarbonate provides oxygen for aquaculture oxygenation and cleaning. Under HTS 2836.99.50 as other peroxocarbonate, excluding main calcium carbonate. Stable solid alternative to liquid peroxides.
Strontium Per Carbonate
Strontium percarbonate used in pyrotechnics and bleaching. HTS 2836.99.50 for other peroxocarbonates. Provides strontium for red flares.
Bismuth Carbonate Basic
Basic bismuth carbonate for pharmaceuticals like antacids. HTS 2836.99.50 other carbonates. Used in Pepto-Bismol analogs.
Thallium Carbonate
Thallium carbonate for research and optics. HTS 2836.99.50 other. Highly toxic specialty chemical.
Ammonium Per Carbonate Solution
Ammonium percarbonate solution for industrial bleaching. HTS 2836.99.50 as other. Liquid form for easy handling.
Zinc Per Carbonate
Zinc percarbonate antiseptic powder. HTS 2836.99.50 other peroxo. For wound care.
Cadmium Carbonate
Cadmium carbonate pigment precursor. HTS 2836.99.50 other. Restricted use.
Potassium Per Carbonate
Potassium percarbonate serves as an eco-friendly bleaching agent in detergents and water treatment, releasing active oxygen. It is categorized under HTS 2836.99.50 as an 'other' peroxocarbonate of potassium, an inorganic base. Ideal for phosphate-free formulations.
Barium Carbonate Precipitated
Precipitated barium carbonate is a high-purity powder used in ceramics, glass manufacturing, and as a rat poison component. Falls under HTS 2836.99.50 as 'other' carbonates, not specifically listed. Its fine particle size ensures reactivity in frits and glazes.
Rubidium Carbonate
Rubidium carbonate, a rare alkali metal salt, is used in specialty glass, fireworks, and research applications. It qualifies under HTS 2836.99.50 as other carbonates of inorganic bases (rubidium). High purity grades support ion-selective applications.
