Sulfuric Acid (CAS 7664-93-9) is a strong, hygroscopic mineral acid (H2SO4), here at 93% concentration. it is used in fertilizer manufacture, petroleum refining, lead-acid batteries, metal cleaning and electroplating (pickling), and in pulp and paper, textile, and glass processing.
Frequently Asked Questions
What is 93% sulfuric acid used for?
Sulfuric Acid 93% (CAS 7664-93-9, H2SO4) is a strong, hygroscopic mineral acid used in phosphate-fertilizer manufacture, petroleum-refinery alkylation and treating, metal pickling, cleaning, and electroplating, as the electrolyte in lead-acid batteries, and in pulp, paper, textile, and glass processing.
What color is 93% sulfuric acid?
Technical 93% sulfuric acid is typically a clear to pale-yellow or amber liquid; exact appearance can vary with grade and trace iron content. Refer to the CoA for the appearance specification of a given lot.
How do you neutralize 93% sulfuric acid?
Concentrated sulfuric acid is typically neutralized by careful addition of a base such as soda ash or lime, always adding acid to a large excess of dilute base with cooling, never water to acid, per your site procedure. Follow the SDS and your facility's protocol; confirm disposal limits with your local authority.
How is 93% sulfuric acid supplied and shipped in bulk?
We supply it to manufacturers in bulk packaging such as drums, totes, and bulk loads. It ships as UN 1830, SULFURIC ACID. CAS is 7664-93-9; HS classification is 2807.00. Request a quote with your volume for current bulk pricing, CoA, and SDS.
What HS code applies to sulfuric acid?
Sulfuric acid is classified under HS 2807.00 (sulfuric acid; oleum). Verify the destination-country tariff line with your customs broker before import.
