Sulfuric Acid (CAS 7664-93-9) is a dense, strongly acidic and dehydrating mineral acid used in chemical synthesis, fertiliser production, metal treatment, water treatment and battery manufacture.

Standard grade offers 98.0% minimum assay. Premium grade offers 98.5% minimum with lower iron, chloride and residue limits, and is recommended for fine-chemical and high-purity processes.

Technical 98% is the standard offer, with premium low-iron, low-chloride 98.5% available. Other strengths (93%, 96% or oleum) can be quoted on request. Always state the % strength with CAS 7664-93-9.

Sulfuric acid is registered under REACH, and it is also a reportable substance under the EU explosives precursors rules (Regulation (EU) 2019/1148), so we may ask for end-use information. We confirm the current status for your application before quoting.

Store in closed, acid-resistant containers or tanks in a cool, ventilated place, away from water, bases, organics, metals and combustible materials. Always add acid to water, never the reverse.

It is a corrosive dangerous good (Class 8, UN 1830 for sulfuric acid above 51%; always confirm on the current SDS). We pack it in UN-approved containers, apply CLP labels and ship through licensed forwarders under IMDG for sea and ADR for European road.

Yes. Laboratory and pilot samples are supplied with a COA and SDS so your team can qualify the grade. Mention sample needs in your enquiry.

REACH status is confirmed before we quote. We advise on importer-of-record arrangements and whether the substance is registered for your use. Send your use descriptor and we will confirm.
