Subheadings
Products classified under Tariff item 2835.22.00
Disodium Phosphate Anhydrous USP
Disodium phosphate anhydrous (Na2HPO4) is a chemically defined inorganic salt of disodium, used as a buffering agent in pharmaceuticals and food processing. It falls under tariff item 2835.22.00 as a phosphate of disodium, meeting the chapter's criteria for separate chemically defined compounds.
Disodium Phosphate Dodecahydrate
Disodium phosphate dodecahydrate (Na2HPO4·12H2O) is a hydrated form of disodium phosphate, used in lab reagents and pharmaceutical laxatives. As a chemically defined inorganic salt, it is classified under tariff item 2835.22.00, with the water of hydration not affecting its classification.
Disodium Phosphate Food Grade
Food-grade disodium phosphate meets FCC standards for use in cheese processing and evaporated milk stabilization. It is a chemically defined disodium salt, classified under tariff item 2835.22.00, provided it contains no organic additives that would exclude it from Chapter 28.
Monosodium Phosphate Anhydrous
Monosodium phosphate anhydrous (NaH2PO4) is a chemically defined inorganic salt used in buffer solutions and flame retardants. It is classified under tariff item 2835.22.00 as a phosphate of monosodium, meeting Chapter 28's criteria for pure compounds.
Monosodium Phosphate Dihydrate
Monosodium phosphate dihydrate (NaH2PO4·2H2O) is an acidulant and sequestrant used in beverages and metal treatment. As a chemically defined inorganic compound of monosodium, it falls under tariff item 2835.22.00, with the hydrate form not altering classification.
Sodium Acid Pyrophosphate
Sodium acid pyrophosphate (Na2H2P2O7) is a polyphosphate of disodium, used as a leavening agent in baking powders and meat products. It is classified under tariff item 2835.22.00 as a phosphate of disodium, since the heading includes polyphosphates whether or not chemically defined.
Sodium Phosphate Dibasic
Sodium phosphate dibasic is a synonym for disodium phosphate, used in molecular biology buffers like PBS. It is a chemically defined disodium salt, classified under tariff item 2835.22.00, regardless of the grade or purity level.
Tetrasodium Pyrophosphate
Tetrasodium pyrophosphate (Na4P2O7) is a polyphosphate used as a dispersant and detergent builder. Although it has four sodium atoms, it is classified under tariff item 2835.22.00 as a polyphosphate of disodium, as the subheading covers polyphosphates of mono- or disodium.
