Products classified under HTS 2807.00.00.00
98% Sulfuric Acid
Concentrated sulfuric acid at 98% purity, a chemically defined inorganic compound used in industrial processes like fertilizer production and metal pickling. It falls under HTS 2807.00.00.00 as sulfuric acid, distinct from diluted forms or mixtures classified elsewhere. This strong acid is essential for chemical manufacturing and petroleum refining.
Oleum (Fuming Sulfuric Acid)
Oleum, a solution of sulfur trioxide in sulfuric acid, appearing as fuming sulfuric acid used in organic synthesis and explosives manufacturing. Classified under HTS 2807.00.00.00 explicitly as oleum, a chemically pure form per Chapter 28 notes. It is handled with extreme care due to its reactivity.
Battery Grade Sulfuric Acid
High-purity sulfuric acid (93-37%) formulated for lead-acid battery electrolyte, meeting strict impurity limits. It qualifies under HTS 2807.00.00.00 as chemically defined sulfuric acid, not as a mixture if purity standards are met per Chapter 28 notes. Widely imported for automotive and UPS battery production.
Technical Grade Sulfuric Acid
Industrial-grade sulfuric acid (98%) for applications like water treatment, mining leachants, and pigment production. Falls under HTS 2807.00.00.00 as a basic inorganic acid, chemically defined without organic stabilizers excluded by chapter notes. Bulk commodity chemical imported in railcars or isotanks.
Electronic Grade Sulfuric Acid
Ultra-high purity sulfuric acid (>99.999%) for semiconductor wafer cleaning and etching in electronics fabrication. Classified in HTS 2807.00.00.00 as pure sulfuric acid, meeting Chapter 28 chemical definition without doping that would shift to 3818. Critical for microchip manufacturing imports.
Pharmaceutical Grade Sulfuric Acid
Low-bioburden sulfuric acid meeting USP/EP standards for API synthesis and vitamin production. Under HTS 2807.00.00.00 as chemically defined acid, pure form without Chapter 28 exclusions. Imported for drug manufacturing compliance.
Food Grade Sulfuric Acid
Dilute sulfuric acid (10-50%) FCC grade for pH adjustment in beverages and stabilizer in pectin. HTS 2807.00.00.00 if chemically pure, per food chemical codex specs excluding mixtures. Used in food processing industries.
20% Dilute Sulfuric Acid
Aqueous sulfuric acid solution at 20% concentration for laboratory and cleaning applications. Still classified under HTS 2807.00.00.00 as chemically defined sulfuric acid, not a mixture per Chapter 28. Common in educational and industrial labs.
