Products classified under Tariff item 2835.29.00
Aluminum Hydrogen Phosphate
Aluminum hydrogen phosphate (Al(H2PO4)3) is an acidic phosphate salt used as a reactive binder in acid-cured refractories and corrosion inhibitors. It is a separate chemically defined compound of aluminum and phosphorus, falling under the 'Other' nitrates tariff item as a phosphate not elsewhere specified.
Aluminum Orthophosphate Powder
Aluminum orthophosphate powder (AlPO4) is a thermally stable, chemically defined compound used in ceramic glazes, dental cements, and optical coatings. As a phosphate of aluminum, it is classified under the 'Other' nitrates item, which covers phosphates not specifically named elsewhere.
Aluminum Phosphate Gel
Aluminum phosphate gel (AlPO4·2H2O) is a colloidal suspension of a chemically defined aluminum phosphate, used as a binder in refractory ceramics and catalyst supports. The gel form is a normal method of putting up this product for transport, and the compound itself falls under the 'Other' nitrates item.
Anhydrous Trisodium Phosphate Powder
Anhydrous trisodium phosphate is the water-free form of Na3PO4, a strong base used in metal pretreatment and food processing as an acidity regulator. It is a chemically defined phosphate of sodium, falling under the 'Other' nitrates item.
Flame Retardant Triammonium Phosphate
Flame retardant triammonium phosphate is a chemically defined (NH4)3PO4 compound optimized for intumescent coatings. As a phosphate of ammonium, it falls under the 'Other' nitrates item, which covers phosphates not specifically named elsewhere.
Food-Grade Aluminum Phosphate
Food-grade aluminum phosphate (E541) is a purified, chemically defined aluminum phosphate used as an emulsifier, stabilizer, and anti-caking agent in processed foods. It is a phosphate salt of aluminum, classifiable under the 'Other' nitrates item as a phosphate not specifically named.
Microencapsulated Triammonium Phosphate
Microencapsulated triammonium phosphate is a chemically defined (NH4)3PO4 compound encapsulated for controlled release in polymer flame retardants. The encapsulation does not alter the chemical identity, so it remains classifiable under the 'Other' nitrates item as a phosphate.
Monoaluminum Phosphate Solution
Monoaluminum phosphate solution (Al(H2PO4)3 in water) is an acidic phosphate salt used as a binder for high-temperature refractories and acid-resistant coatings. The aqueous solution is a normal method of putting up this product for transport, and the phosphate compound falls under the 'Other' nitrates item.
Sodium Aluminum Phosphate
