Sulphuric Acid (H₂SO₄) is one of the most important and widely used industrial acids in the world. It is considered a fundamental chemical and one of the highest-volume chemicals consumed in Thailand, particularly in the fertilizer, chemical, metallurgical, energy, and battery industries.
Witcorp Products Co., Ltd. is one of Thailand’s leading importers and distributors of Sulphuric Acid, with an annual distribution volume exceeding 200,000–300,000 metric tons. Our supply network covers both the domestic Thai market and neighboring CLMV countries (Cambodia, Laos, Myanmar, and Vietnam).
One of the key strengths of Witcorp Products Co., Ltd. is its Sulphuric Acid tank storage facility with a total capacity exceeding 35,000 metric tons, strategically located along the Chao Phraya River. This robust infrastructure significantly enhances the company’s capability as a leading sulphuric acid distributor in Thailand and ensures a stable, reliable supply to meet the demands of both the domestic market and the CLMV region (Cambodia, Laos, Myanmar, and Vietnam).
We source Sulphuric Acid from internationally recognized manufacturers in China, Korea, and Japan, all of whom operate under globally accepted production technologies and international quality standards.

Sulphuric Acid Production Methods
Industrial Sulphuric Acid is primarily produced through two main processes:
- Sulphur Burner Process
Sulphuric Acid is produced by burning elemental sulphur to generate sulphur dioxide (SO₂), which is subsequently converted into sulphuric acid through catalytic oxidation and absorption processes. - By-Product Method
Sulphuric Acid is produced from sulphur dioxide (SO₂) gas generated as a by-product of metal smelting operations, such as copper, zinc, or other non-ferrous metals.
