Sulfuric Acid Manufacturer in India: Uses, Applications & Bulk Supply Guide

Walk into any fertilizer plant in Gujarat and you'll spot drums of it stacked near the loading bay. Sulfuric acid. Not a glamorous name. Does most of the heavy lifting anyway.

Vrik Pharma has been manufacturing and supplying this acid out of Gujarat for close to 18 years now, from a facility in Sarigam GIDC. We're an ISO-certified inorganic chemicals company, and honestly, if you're looking for a sulfuric acid manufacturer who actually understand bulk industrial supply — not just a trading firm reselling someone else's stock — that's the whole point of writing this.

So let's get into it. What is this acid, where does it go, and what should you check before ordering a tanker of the stuff from your sulfuric acid manufacturer.

What Is Sulfuric Acid?

H₂SO₄. CAS number 7664-93-9. That's the identity card.

In concentrated industrial form it's a colorless to slightly yellow liquid, thick and viscous, molecular weight sitting around 98.08 g/mol. Mix it with water and it dissolves completely — but the reaction throws off a lot of heat, fast. That's why every safety sheet says the same thing: acid goes into water, never the other way. Get that backwards and things get ugly quick.

Industrial Applications of Sulfuric Acid

Three things make this acid useful across industry. It dehydrates aggressively, it catalyzes reactions well, and it's a cheap, reliable source of sulfate. Which property matters most just depends who's buying.

Fertilizer Manufacturing

This is the big one. Most of the acid produced worldwide ends up here, reacting with phosphate rock to make phosphoric acid and single superphosphate. A fertilizer manufacturer can't afford much variation in concentration — even a small swing throws the downstream chemistry off, and that costs money.

Chemical and Metal Processing

Chemical plants use it to make other acids — hydrochloric, nitric — plus a long list of sulfate salts. Metal processing units use it differently, for pickling, stripping rust and oxide scale off steel before it gets galvanized or coated.

Petroleum Refining and Batteries

Refineries run it through the alkylation process to boost octane in gasoline blends. It's also sitting inside every lead-acid battery as the electrolyte, and it shows up in water treatment too, controlling pH before other treatment steps kick in.

Sulfuric Acid Specifications

Here's a general spec sheet, the kind most buyers ask for upfront.

Parameter	Typical Value
Chemical Formula	H₂SO₄
CAS Number	7664-93-9
Molecular Weight	98.08 g/mol
Appearance	Colorless to slightly yellow liquid
Concentration	93%–98% (other concentrations available on request)
Density	~1.84 g/cm³ at 98% concentration
Grade	Industrial, Fertilizer, or Battery grade
Solubility	Fully miscible with water (exothermic)

What to Check Before You Buy Sulfuric Acid in Bulk

Every procurement manager we talk to end up asking the same handful of questions, more or less. Doesn't matter if they're in fertilizers or metal processing. It comes down to this:

Buying Criteria	Why It Matters
Concentration & consistency	Downstream reactions depend on a stable input
Purity / contaminant control	Trace metals can mess with fertilizer or battery-grade use
COA & MSDS availability	Needed for compliance and internal QA sign-off
Packaging	HDPE drums, IBC tanks, or bulk tankers suited for hazardous liquid transport
Regulatory documentation	Required for domestic dispatch and export clearance both
Supplier track record	Affects lead time and whether batch three matches batch one

That last one trips people up more than you'd think. A supplier can hit spec once and still be inconsistent over six months. Ask for batch history, not just a single COA — a genuine sulfuric acid manufacturer won't have a problem sharing that.

Handling and Storage

This part isn't optional. Sulfuric acid is corrosive, full stop. Only trained personnel should be handling it, and always with acid-resistant PPE and a face shield. Store it in corrosion-resistant containers, keep it away from organic material and anything it might react with. Follow the acid-to-water rule every single time you dilute it. Keep an MSDS on-site. Disposal has to go through proper hazardous-waste channels, no shortcuts there.

Sourcing Sulfuric Acid From an Indian Manufacturer

If you're buying in volume, geography actually matter. Working with a sulfuric acid manufacturer in India based near a real industrial corridor saves on both freight and turnaround time.

That's where Vrik Pharma fits in. We manufacture and supply sulfuric acid from our Sarigam GIDC facility, with corporate operations based in Vapi, Gujarat. Eighteen years in inorganic and specialty chemicals, ISO-certified, and we supply fertilizer manufacturers, chemical processors, metal treatment units, and refineries across India — plus exports, with full documentation handled on our end. Every dispatch ships with a Certificate of Analysis and MSDS, and packaging comes as HDPE drums, IBC tanks, or bulk tankers depending on how much you need.

That's the short version. Whether you're a fertilizer manufacturer needing consistent monthly supply or a one-time industrial buyer, the fundamentals don't change: check the spec sheet, check the documentation, check the track record. Then place the order.
