Safety and handling
Highly Corrosive handle with protection
Contact causes severe skin and eye burns, and inhaling mist irritates the respiratory tract, so gloves, eye protection, and proper ventilation are required.
- Always add acid to water, never water to acid — dilution is violently exothermic and causes splashing.
- Store in corrosion-resistant containers in a cool, dry, well-ventilated area away from water, metals, and organic materials.

Both are the same chemical, sulphuric acid, at different strengths. Concentrated (98%) is closer to pure acid and more aggressive to handle, dilute (50 to 70%) is pre-diluted for processes that dose the acid directly without further dilution. Which one you order depends on your process setup.
Yes. It's classified as corrosive (UN 1830, Class 8) and causes severe skin and eye burns on contact, especially in concentrated form. It is not flammable but reacts violently with water and many organic materials.
Sulphuric acid ships in 35kg and 40kg containers, or in bulk for larger orders. Our minimum order quantity is 500kg; above that, we supply any quantity your production needs.
In corrosion-resistant containers, in a cool, dry, well-ventilated area, away from water, metals, and organic materials.
