Product Overview
Hydrochloric Acid 15% Technical Grade is a mid-strength aqueous solution of hydrogen chloride — a clear, colorless to light yellow liquid with a pungent, irritating odor. At 15%, it delivers real acid-cleaning and pH-control power without the aggressive fuming behavior of concentrated grades, which is why water-treatment operators, metal-finishing shops, and maintenance crews reach for it as a working-strength acid they can dose straight from the container. we distribute it in our Taylor, TX warehouse and ship it daily in DOT-compliant corrosive packaging, from single quarts to 330 gallon totes.
Why This Concentration
Pick 15% when you want a solution strong enough to cut rust, scale, and alkalinity in one pass, but dilute enough to handle with standard corrosive-service PPE and dose with less risk of overshooting. Many buyers who start with concentrated acid and a dilution step switch to 15% simply to remove that step — no exothermic mixing at the point of use, no acid-to-water procedure on the shop floor.
If your process only needs light pH trimming or gentle surface cleaning, Hydrochloric Acid 5% Technical Grade gives you finer control with less corrosive load on equipment. If you dilute on site at volume or need maximum strength per gallon shipped, Hydrochloric Acid 31% Technical Grade is the more economical way to move acid — provided you have the ventilation and procedures to handle it. Technical grade fits applications where trace impurities do not affect the outcome: cleaning, descaling, pH adjustment, and general industrial use.
Chemical Profile
This product is hydrogen chloride (formula ClH, molecular weight 36.46, CAS 7647-01-0) dissolved in water at 15% strength. It presents as a clear, colorless to light yellow liquid with the sharp, irritating odor characteristic of hydrochloric acid. Density is 1.075 g/mL for the 15% w/w aqueous solution at 20 °C — noticeably heavier than water, which matters when you are sizing pumps or calculating dose by weight. It is miscible with water in all proportions, so in-line dilution and metered feed are straightforward.
Industrial Applications
-
pH adjustment in water treatment. Operators feed hydrochloric acid to lower pH and neutralize alkalinity in process water, wastewater, and cooling systems. The 15% strength doses predictably through standard chemical-feed equipment.
-
Metal cleaning and descaling. The acid dissolves rust (iron oxide) and mineral scale from steel and other metal surfaces ahead of coating, welding, or inspection. At 15%, it works fast on oxide layers while remaining manageable for immersion and spray-wand work.
-
Chemical synthesis. Hydrochloric acid serves as an acidification and chloride-source reagent in industrial chemical processing, where a pre-diluted working strength saves a preparation step.
-
Laboratory reagent. A common bench acid for acidification, cleaning glassware, and general wet-work where technical purity is acceptable.
Handling & Storage
The signal word for this product is Danger (per the product's GHS classification). Its hazard statements: H290 May be corrosive to metals, H314 Causes severe skin burns and eye damage, and H335 May cause respiratory irritation (per the product's GHS classification). Treat it accordingly. Wear acid-resistant gloves, splash goggles or a face shield, and chemical-resistant clothing whenever you open a container or transfer product. Work with ventilation — the vapor is irritating to the respiratory tract.
Store it cool and dry in corrosion-resistant containers — HDPE or glass, never bare metal. Keep it away from metals it can attack and from strong bases, which react violently with acids. Keep containers closed when not in use, and segregate acid storage from incompatible materials. If you must dilute further, always add acid to water slowly with stirring, never the reverse. This guidance is reviewed by Andre Taki, DOT Hazmat Specialist.
Hazmat & Shipping
This is a regulated corrosive material. It ships as UN1789 (per 49 CFR 172.101), Hazard Class 8 (per 49 CFR 172.101), Packing Group II (per 49 CFR 172.101), under the proper shipping name "Hydrochloric acid" (per 49 CFR 172.101). Every order leaves our dock in UN-rated packaging with correct hazmat labels, markings, and shipping papers. We pack and ship Class 8 corrosives daily, so your freight arrives compliant and ready to receive — no surprises for your receiving dock or your carrier.
Documentation
A Safety Data Sheet ships with every order, available in English, Spanish, French, and Japanese. A Technical Data Sheet is available for spec review before you buy, and a lot-specific Certificate of Analysis is available with your shipment so your QC team can verify the material against its actual production lot.
