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.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If contains additives like expanders or demineralized water beyond pure acid
Battery electrolytes with intentional mixtures are prepared chemicals in 3824, not pure acids.
If imported filled in lead-acid batteries
Complete batteries with electrolyte are classified by function in Chapter 85.
If converted to sulfate salts like zinc sulfate
Metal sulfates are under heading 2833, separate from free acid.

Import Tips & Compliance
• Provide assay reports showing low heavy metals for battery grade verification; comply with EPA pre-notification for corrosive imports
• Avoid pitfall: over-dilution pushes to 3824 as chemical prep

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.
Technical Grade Sulfuric Acid
Industrial-grade sulfuric acid (98%) for applications like water treatment, mining leachants, and pigment production.
