Products classified under HTS 2840.20.00.00
Sodium Tetraborate Decahydrate (Borax)
Sodium tetraborate decahydrate, commonly known as borax, is a hydrated sodium borate salt used in detergents, glass manufacturing, and as a flux. It falls under HTS 2840.20.00.00 as 'other borates' since it is a chemically defined inorganic borate compound excluding peroxoborates. This white crystalline powder is essential in cleaning products and metallurgy.
Disodium Tetraborate Anhydrous
Disodium tetraborate anhydrous is a dehydrated form of borax used in industrial applications like enamel frits and herbicides. Classified under HTS 2840.20.00.00 as other borates, it is a pure inorganic sodium borate meeting Chapter 28 definitions. This powder provides boron source in metallurgy and agriculture.
Potassium Tetraborate
Potassium tetraborate is an inorganic salt used as a boron source in welding fluxes and ceramics. It is classified in HTS 2840.20.00.00 as other borates, distinct from sodium borates. This compound appears as a white powder soluble in water.
Ammonium Pentaborate Solution
Ammonium pentaborate solution (20-40% concentration) serves as a fire retardant and boron supplement in agriculture. Under HTS 2840.20.00.00 as other borates, it qualifies as chemically defined per Chapter 28/29 notes despite solution form. Used in wood treatment and fertilizers.
Zinc Borate Powder (2ZnO·3B2O3·3.5H2O)
Zinc borate (2ZnO·3B2O3·3.5H2O) is a flame retardant and smoke suppressant used in plastics and textiles. Classified as other borates under HTS 2840.20.00.00 as a metal borate salt per heading applicability. Fine white powder with specific hydrate formula.
Magnesium Borate Hydrate
Magnesium borate hydrate serves as a lubricant additive and anti-corrosion agent. It falls under HTS 2840.20.00.00 as other borates, being a chemically defined inorganic magnesium salt. Used in drilling fluids and ceramics.
Calcium Borate Precipitate
Calcium borate precipitate is used in specialty ceramics and as a boron supplement. Classified under HTS 2840.20.00.00 as other borates, excluding Chapter 31 products. Fine particulate form for high-purity applications.
Barium Borate
Barium borate is employed in optical glass and X-ray screens. It is an other borate under HTS 2840.20.00.00, chemically defined inorganic compound. Provides refractive index control in glassmaking.
Cadmium Borate
Cadmium borate finds use in phosphors and specialty pigments. Classified as other borates in HTS 2840.20.00.00 as metal borate. Highly regulated due to cadmium toxicity.
Lead Borate
Lead borate is used in glass-to-metal seals and radiation shielding glass. Falls under HTS 2840.20.00.00 as other borates, metal borate compound. Provides high density and fusion properties.
Sodium Peroxoborate (Incorrectly Shipped)
Sodium peroxoborate is sometimes misdeclared but belongs in 2840.11; example of classification risk. HTS 2840.20.00.00 applies only to non-peroxy borates per subheading note. Used in bleaching if pure borate form.
