Hydrochloric acid (HCl) is a strong, versatile mineral acid supplied as an aqueous solution, most commonly at 30–35%. It is one of the most widely used acids in industry, essential for steel pickling, chemical manufacture, oil-well acidising, water treatment, pH control, food processing (as E507) and the production of chlorides and many other chemicals. Much of the world's hydrochloric acid is recovered as a co-product of other chemical processes (such as the chlorination of organics), making it both widely available and cost-effective. It is graded by concentration and purity - technical grade for industrial use and food grade (E507) for food and pharmaceutical applications. Industrial buyers sourcing Hydrochloric Acid in bulk also track hydrochloric acid pricing closely, since it feeds directly into their downstream costs - which is why working with an established hydrochloric acid supplier and distributor like Elchemy matters.
Hydrochloric acid is produced by two main routes: direct synthesis, in which hydrogen and chlorine are burned together to form hydrogen chloride gas that is absorbed in water; and, more commonly, as a by-product of the chlorination of organic compounds, where the evolved HCl gas is absorbed into water to form the acid. The gas is absorbed in a falling-film absorber to the target concentration (typically 30–35%) and purified for food or technical grade. As a quality-focused hydrochloric acid manufacturer and sourcing partner, Elchemy tests every shipment for assay (concentration), iron, free chlorine and heavy metals before dispatch, with a Certificate of Analysis travelling alongside each order.
If you are comparing hydrochloric acid price for bulk procurement, Elchemy provides quotes based on your exact requirements. Share your volume, grade, destination and packaging on the quote form and our team reverts with a detailed offer within 24 to 48 hours. Pricing is quoted rather than published because the cost is driven by chlor-alkali economics and the availability of by-product HCl from organic chlorination, not a fixed list. This is why a live quote from a hydrochloric acid supplier is always more accurate than any headline figure. Beyond that, several factors shape the final hydrochloric acid price: grade, committed volume, origin country, packaging format, freight, Incoterm (FOB, CIF or DDP) and import duty (HTS 2806.10 for US-bound shipments). For an approximate read on where the market sits, procurement teams often reference chlor-alkali and hydrochloric acid price indices. Trade publications also report the hydrochloric acid price per kg as a unit-level benchmark, useful for spotting short-term regional shifts. At bulk procurement scale, the hydrochloric acid price per ton (or per MT) is the most relevant commercial unit, since contracts are negotiated at that level. For an exact rate, none of these replaces a direct quote. Your final price depends on contract structure, destination, volume and timing - so a quote from our team is always the most accurate number for your procurement.
Hydrochloric Acid ships in standard export packaging - bags, drums, IBCs or bulk as the material requires - with both metric and imperial weights, supplied to your specification. A typical 20' container holds a full commercial load depending on packaging. For US, UK and UAE buyers, Elchemy arranges compliant freight and customs documentation, offering EXW, FOB, CIF and DDP terms. Transit times and stock position are confirmed at quotation, and samples are dispatched within 24 to 48 hours. Store per the conditions on the TDS. As a global hydrochloric acid distributor, Elchemy ships to 40+ countries with the documentation each destination market requires.
Elchemy makes sourcing Hydrochloric Acid straightforward for industrial buyers. Every order ships with a Certificate of Analysis, TDS and GHS-aligned SDS as standard, across the grades listed above. Because we source across multiple origins, we quote the best landed cost for your destination rather than a single hydrochloric acid manufacturer's list price. Partner plants operate to recognised quality standards (ISO 9001, plus food/pharma certifications where relevant), with Halal and Kosher documentation on request. From the USA and UK to the UAE and beyond, Elchemy serves as a single hydrochloric acid supplier, manufacturer and distributor relationship - with samples before bulk and pricing tailored to your volume and contract terms.
Classified under GHS as Skin Corrosive Category 1B (H314), STOT SE 3 (H335). DOT/UN: UN1789, Class 8 Corrosive, Packing Group II–III (concentration-dependent). Hydrochloric acid is corrosive and hazardous. It causes severe burns to skin and eyes and its pungent, fuming vapour damages the respiratory tract and, over time, tooth enamel. It reacts with metals to release flammable hydrogen gas, and with oxidisers (e.g. bleach) to release toxic chlorine gas - the two must never be mixed. Handle with full chemical PPE and strong ventilation, store in acid-resistant, vented containers, and always add acid to water when diluting. It is a listed explosives precursor with consumer-supply restrictions in several markets. The full 16-section GHS-aligned SDS is available alongside every Hydrochloric Acid order.
