Products classified under Tariff item 28.07
20% Dilute Sulfuric Acid
A 20% aqueous solution of sulfuric acid, a separate chemically defined compound dissolved in water. It falls under this tariff item as a solution of sulfuric acid, consistent with Chapter 28 Note 1(b) which covers such aqueous solutions.
2807.00.0098% Sulfuric Acid
Concentrated sulfuric acid at 98% purity, a separate chemically defined inorganic compound. It is classified here as sulfuric acid, meeting Chapter 28 Note 1(a) requirements for pure chemical compounds, and is widely used in industrial processes.
2807.00.00Battery Grade Sulfuric Acid
High-purity sulfuric acid (93-37%) formulated for lead-acid battery electrolyte, with strict impurity limits. It is classified here as chemically defined sulfuric acid, provided it does not contain additives that render it suitable for specific use beyond general acid applications.
2807.00.00Electronic Grade Sulfuric Acid
Ultra-high purity sulfuric acid (>99.999%) for semiconductor wafer cleaning and etching. It is a separate chemically defined compound, classified here as sulfuric acid, meeting Chapter 28 Note 1(a) without any doping or additives that would exclude it.
2807.00.00Food Grade Sulfuric Acid
Dilute sulfuric acid (10-50%) FCC grade for pH adjustment in beverages and as a stabilizer in pectin. It is classified here as a chemically defined aqueous solution of sulfuric acid, provided it meets Chapter 28 Note 1(b) without added food additives.
2807.00.00Oleum (Fuming Sulfuric Acid)
Oleum, also known as fuming sulfuric acid, is a solution of sulfur trioxide in sulfuric acid. It is explicitly named in this tariff item and is classified here as oleum, a chemically defined product used in organic synthesis and explosives manufacturing.
2807.00.00Pharmaceutical Grade Sulfuric Acid
Low-bioburden sulfuric acid meeting USP/EP standards for API synthesis and vitamin production. It is a chemically defined acid, pure form without Chapter 28 exclusions, and is classified here as sulfuric acid for pharmaceutical manufacturing.
2807.00.00Technical Grade Sulfuric Acid
Industrial-grade sulfuric acid (98%) for applications like water treatment, mining leachants, and pigment production. It is a basic inorganic acid, chemically defined without organic stabilizers, and is classified here as sulfuric acid.
