Products classified under HTS 2836.99.50.50
Sodium Percarbonate Powder
Sodium percarbonate is a white, crystalline powder used primarily as an oxygen bleach in laundry detergents and cleaning products. It falls under HTS 2836.99.5050 as a peroxocarbonate (percarbonate) of an inorganic base (sodium), classified as 'other' within the carbonates and peroxocarbonates heading. This chemically defined compound releases hydrogen peroxide when dissolved in water, making it an effective bleaching agent.
Lithium Carbonate Crystals
Lithium carbonate is a white, odorless powder or crystalline material used in pharmaceuticals, glass manufacturing, and lithium-ion battery production. It is classified under HTS 2836.99.5050 as 'other' carbonates of inorganic bases (lithium), per Chapter 28 notes restricting carbon compounds. This essential compound for mood stabilizers and ceramics meets chemically defined criteria.
Potassium Bicarbonate Powder
Potassium bicarbonate is a white, crystalline powder used as a leavening agent in baking, pH buffer in beverages, and fire suppressant. It qualifies under HTS 2836.99.5050 as an 'other' carbonate of an inorganic base (potassium), adhering to Chapter 28 restrictions on carbon compounds. This food-grade chemical is stable and soluble in water.
Magnesium Percarbonate Granules
Magnesium percarbonate granules serve as an eco-friendly bleaching and oxidizing agent in detergents and water treatment. Classified in HTS 2836.99.5050 as 'other' peroxocarbonates of inorganic bases, it decomposes to release oxygen and is noted in Chapter 28 for such compounds. This stable solid alternative to liquid peroxides is granular for easy handling.
Barium Carbonate Fine Powder
Barium carbonate fine powder is used in ceramics, glass, and rat poisons due to its high density and reactivity. It is an 'other' carbonate under HTS 2836.99.5050, as a chemically defined inorganic base compound per Chapter 28. This toxic white powder requires careful handling.
Strontium Carbonate Precipitated
Precipitated strontium carbonate is a high-purity white powder for pyrotechnics, magnets, and TV tube glass. HTS 2836.99.5050 covers it as 'other' carbonates of inorganic bases, fitting Chapter 28 definitions. Its fine particle size ensures reactivity.
Calcium Percarbonate Technical Grade
Technical grade calcium percarbonate is used in aquaculture oxygenation and mild bleaching. As a peroxocarbonate, it is 'other' under HTS 2836.99.5050, per Chapter notes on inorganic peroxocarbonates. It effervesces in water to release oxygen.
Rubidium Carbonate Solution Crystals
Rubidium carbonate crystals from solutions are specialty chemicals for research and specialty glass. Rare earth-like, classified 'other' carbonates in HTS 2836.99.5050. High purity for atomic clocks and photoelectrics.
Cesium Carbonate Anhydrous
Anhydrous cesium carbonate is a strong base for organic synthesis and catalysts. HTS 2836.99.5050 as 'other' inorganic carbonate. Hygroscopic white powder.
Commercial Sodium Sesquicarbonate
Sodium sesquicarbonate (Na2CO3.NaHCO3.2H2O) is a double salt for detergents and water softening. 'Other' under HTS 2836.99.5050; complex carbonates per notes. Trona-derived natural mineral.
Thallium Carbonate Lab Grade
Lab-grade thallium carbonate for toxicology studies and specialty optics. Toxic 'other' carbonate HTS 2836.99.5050. Highly poisonous.
