Subheadings
Products classified under Tariff item 2818.30.00
Aluminum Hydroxide Flame Retardant Filler
Micronized aluminum hydroxide used as a halogen-free flame retardant and smoke suppressant in plastics and rubber. It is a chemically defined compound (Al(OH)3) of high purity, meeting the terms of Chapter 28 Note 1(a) and classified under tariff item 2818.30.00.
Aluminum Hydroxide Gel USP (Antacid Suspensions)
USP-grade aluminum hydroxide gel for liquid antacid formulations and phosphate binders. Despite being in gel form, it is a chemically defined compound of aluminum hydroxide, meeting Chapter 28 Note 1(b) as a product dissolved or suspended in water, and is classifiable under tariff item 2818.30.00.
Aluminum Hydroxide Paper Filler Precipitate
Precipitated aluminum hydroxide used as a retention aid and filler in alkaline paper manufacturing. With chemical purity exceeding 99.5% Al(OH)3, it qualifies as a separate chemically defined compound under Chapter 28 Note 1(a) and is classified under tariff item 2818.30.00.
Aluminum Hydroxide Powder (Pharmaceutical Grade)
Fine aluminum hydroxide powder used as an antacid in pharmaceutical formulations. It is a chemically defined compound of high purity, distinct from mixed or impure preparations, and therefore falls under tariff item 2818.30.00 as aluminum hydroxide.
Athermal Aluminum Trihydroxide (Cable Compounds)
High-purity aluminum trihydroxide (ATH) processed for low-smoke zero-halogen (LSZH) cable insulation compounds. It is a chemically defined compound with optimized particle morphology, meeting Chapter 28 Note 1(a) and classified under tariff item 2818.30.00.
Gibbsite Aluminum Hydroxide (Bayer Process)
Crystalline gibbsite form of aluminum hydroxide produced via the Bayer process from bauxite ore. It is a pure aluminum hydroxide mineral and a chemically defined compound, classifiable under tariff item 2818.30.00, despite its natural origin, as it is not a precious stone or metal.
Hydrated Alumina Precipitate (Water Treatment)
Precipitated aluminum hydroxide used as a coagulant in municipal and industrial water purification systems. It is a chemically defined compound of aluminum hydroxide, meeting Chapter 28 Note 1(a), and is classified under tariff item 2818.30.00 for its role in water treatment.
Nano-Aluminum Hydroxide Precipitate
Ultrafine 50-100nm aluminum hydroxide nanoparticles for transparent flame retardant coatings and advanced composites. Despite nanoscale, it is a chemically defined compound with unchanged composition, meeting Chapter 28 Note 1(a) and classified under tariff item 2818.30.00.
