Boric acid — H3BO3, CAS 10043-35-3, also called orthoboric acid — is a white, odourless powder or crystalline granules, soluble in water, glycerine, and alcohols. Supreme Petro Chemicals stocks boric acid at our Redhills, Chennai warehouse, in 25 kg bags up to 500 kg jumbo bags. This guide covers what boric acid is, where it is used, and what to state on an enquiry.
What Is Boric Acid?
Boric acid is a boron-based inorganic acid — a white, odourless solid supplied as powder or crystalline granules. It dissolves at 5 g/100 mL in water at 20°C and is also soluble in glycerine and alcohols, which is why it appears in water-based, glycerine-based, and alcohol-based formulations alike.
For logistics it is an easy material: not classified as dangerous goods, so it ships as general cargo without dangerous-goods documentation. Kept cool and dry, it carries a 36-month shelf life from manufacture.
Purity
The product specification for our boric acid is ≥ 99.0% purity. The product page carries the full specification table, and a batch Certificate of Analysis is supplied with every delivery. If your process needs a particular standard or certificate, state it on the enquiry so it can be checked before you order.
Uses by Industry
- Industrial processing: general technical duty wherever a boron source is specified.
- General formulation work: wherever a water-, glycerine-, or alcohol-soluble boron source is required.

FAQ
What is the CAS number and HSN code for boric acid?
CAS 10043-35-3; HSN code 2810 00 20 in Indian trade. Quote both on purchase orders to avoid ambiguity.
Is boric acid the same as borax?
No. Boric acid is H3BO3. Borax is sodium tetraborate decahydrate — Na2B4O7·10H2O, CAS 1303-96-4 — a granular borate powder used in detergent formulations, glass and ceramic fluxes, and metallurgical fluxes. Both are borates and both supply boron, but they are different compounds and not interchangeable in a formulation.
Is boric acid a dangerous good for transport?
No. It is not regulated for transport and not classified as dangerous goods, so it moves as general cargo. Store it in a cool, dry, well-ventilated area away from strong bases and oxidisers; shelf life is 36 months from manufacture.
