Safety and handling
Corrosive & Strong Oxidiser handle with protection
Contact causes severe skin and eye burns, and releases toxic, corrosive fumes, so gloves, eye protection, and dedicated ventilation are required.
- Strong oxidiser: reacts violently with organic materials, metals, and reducing agents keep away from combustible materials.
- Store in corrosion-resistant containers in a cool, well-ventilated area away from direct heat and sunlight.

Frequently asked questions

Both are the same chemical, nitric acid, at different strengths. Concentrated (68%) is more aggressive and used for etching and passivation, dilute (40 to 55%) suits processes that dose the acid directly at lower strength. Which one you order depends on your application.
Yes. It's classified as corrosive with oxidising properties (UN 2031, Class 8, subsidiary 5.1) and causes severe skin and eye burns, plus toxic fumes on contact with air or organic material. It is not flammable itself but intensifies fires.
Nitric 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, well-ventilated area, away from combustible materials, metals, and reducing agents.
