About Sulfuric Acid

Alliance Chemical supplies sulfuric acid (H2SO4, CAS 7664-93-9) in concentrations from 30% to 96%. Compare grades, package sizes and current prices in the table above. Match both concentration and grade to your purchasing specification; a higher percentage does not establish a higher purity grade.

Choose the concentration and grade separately

The 30%, 37% Battery Acid, 70% and 93% products are Technical Grade. The 50% product is Electrolyte Grade, and the 96% product is ACS Reagent Grade. Check product specifications and the lot certificate against any required impurity limits.

Drain Hammer is a separate 93% Technical Grade drain-cleaner product. Follow its product label; do not treat its application name as a laboratory or electrolyte specification.

Battery acid and routine battery maintenance

The 37% Battery Acid product is Technical Grade. It is distinct from the 50% Electrolyte Grade product. Neither concentration is a general recommendation for topping up a battery: for routine flooded lead-acid battery watering, Trojan Battery instructs users to add water, never acid. Follow the battery manufacturer's instructions for your equipment. See our flooded-battery watering and winter-care guide for context.

Quart bottles through bulk totes

The seven commercial products above offer 1-quart, 1-gallon, 5-gallon, 15-gallon, 55-gallon, 275-gallon and 330-gallon size options. Open the selected product for case quantities, current prices and availability. The separate NSN 6810-00-823-8007 and NSN 6810-00-236-0702 procurement listings should be ordered against their own specifications.

Review product documents and request a quote

Use the document pages for 37% Battery Acid, 50% Electrolyte Grade, 93% Technical Grade and 96% ACS Reagent Grade to review SDS and technical data. Request a lot-specific Certificate of Analysis for receiving or acceptance records; a typical certificate does not identify your shipment's lot.

For multiple containers or recurring supply, request a sulfuric acid bulk quote with concentration, grade, container size, quantity and delivery ZIP code. Package and shipping options depend on the selected product and destination. Review the exact-product SDS for handling and storage, and the sulfuric acid DOT reference for concentration-dependent transport classifications.

Frequently Asked Questions

Where can I buy sulfuric acid?
You can order sulfuric acid from Alliance Chemical in concentrations from 30% to 96%, including 37% Battery Acid, 50% Electrolyte Grade and 96% ACS Reagent Grade. Compare the products above, then select the grade, concentration and package size for current pricing and availability. For multiple containers or repeat orders, request a bulk quote.
Which sulfuric acid concentration do I need?
Use the concentration and purity grade required by your process, laboratory method or equipment manufacturer. Alliance's 30%, 37%, 70% and 93% sulfuric acid products are Technical Grade; the 50% product is Electrolyte Grade and the 96% product is ACS Reagent Grade. The 37% Battery Acid name does not make it interchangeable with the 50% Electrolyte Grade product. Compare the product specification and lot certificate before ordering.
Should I top up a lead-acid battery with sulfuric acid?
For routine watering of a flooded lead-acid battery, use water as directed by the battery manufacturer, not sulfuric acid. Trojan Battery's maintenance guidance explicitly instructs users to add water rather than acid. Follow the instructions for your specific battery; purchasing a product labeled battery acid is not a routine maintenance recommendation.
Can I buy sulfuric acid in bulk?
Yes. The commercial sulfuric acid products in this collection offer 55-gallon drums and 275-gallon and 330-gallon totes, along with smaller packages. Request a bulk quote with the required concentration, grade, container quantity and delivery ZIP code so the order and freight requirements can be confirmed.
Who can buy sulfuric acid?
Alliance Chemical offers sulfuric acid for online purchase. Under 21 CFR 1310.08(a), domestic and import sulfuric acid transactions are excluded from the regulated transactions covered by that section. That exclusion does not establish every requirement for a particular location, use or export. Contact Alliance with the destination and order details when those requirements need confirmation.
How is sulfuric acid shipped?
Shipping arrangements depend on the selected concentration, package size, quantity and destination. Check the product's SDS and the available shipping options for your order, or request a freight quote for bulk quantities. The sulfuric acid DOT reference explains the concentration bands used for transport classification.
What sulfuric acid concentrations are available?
The published commercial range includes 30%, 37%, 50%, 70%, 93% and 96%. Technical Grade is offered at 30%, 37%, 70% and 93%; Electrolyte Grade at 50%; and ACS Reagent Grade at 96%. Drain Hammer is a separate 93% Technical Grade product. A listed concentration does not imply that every grade is available at that strength.
What is sulfuric acid used for?
Sulfuric acid is used in battery electrolyte systems, metal finishing and anodizing, industrial pH adjustment, chemical processing and laboratory methods. Those applications require their own concentration, purity and equipment specifications. Select against the applicable specification rather than treating a general use list as product approval; routine battery watering does not call for adding acid.
How should sulfuric acid be diluted?
Dilution releases substantial heat. Follow the exact-product SDS and an established procedure with suitable equipment, protection and temperature control. The general order is acid into water, never water into concentrated acid; this reminder is not a complete dilution procedure. Start with the product SDS and your site's approved instructions.
Is sulfuric acid hazmat?
Yes. 49 CFR 172.101 lists sulfuric acid with more than 51% acid as UN1830 and sulfuric acid with not more than 51% acid as UN2796, both Class 8, Packing Group II. Confirm the selected product's SDS and shipment details; packaging and transport requirements depend on the actual shipment.
Do sulfuric acid products include documentation?
Product document pages provide SDS and technical data, including pages for 37% Battery Acid, 50% Electrolyte Grade, 93% Technical Grade and 96% ACS Reagent Grade. For a shipment-specific quality record, request the Certificate of Analysis for your lot. A typical certificate is not a substitute for the lot-specific record.
