Since establishment in 1980 as a trading company specialized in chemicals, we, TOSCO Co., Ltd., have been supplying Japanese customers with high quality chemicals manufactured in Europe, North America and mainly China.
Based on the company growth, we established Tosco Pharmachem Pvt Ltd as a subsidiary in India and merged an excellent chemical company of GM Fine Chemicals that had the manufacturing facilities in Hyderabad and Visakhapatnam.
GM Fine Chemicals supplies a variety of APIs and intermediates to the pharmaceutical companies in Europe, USA and Japan. Additionally, they have “Accreditation certificate of foreign manufacturer” that authorizes the manufacturing of APIs for Japanese market. This merger enabled the manufacturing of APIs and intermediates at our own plant as well as the process development.
Thus, we have completed a new supplier system that functions as not only a manufacturer but also a trading company.
In Japan, more medical expenses are being expected currently owing to aging progress. Now, TOSCO Co., Ltd. aims for realization of an enriched aging society by contributing to medical care through stable supply of high-quality APIs and pharmaceuticals including generics at an affordable price.

3. High Quality, Low Cost, Stable Supply
We achieve our mottos of “High Quality”, “Low Cost” and “Stable Supply” based on advanced technology, state-of-the-art equipment and flexible and quick response.
- High Quality products satisfying the Japanese strict standard.
- Low Cost manufacturing in India.
- Flexible and Quick Response based on manufacturing at our own plant.
India is a country with the largest number of pharmaceutical colleges and universities in the world, and is engaged in the development of API industry as well as human resources.
Plant in India is working on complying with GMP according to Schedule “M” WHORTSICH and relevant guidelines for Purity, Identity, Strength, Safety, Efficiency and Quality in order to supply the required APIs to our customers.
R&D Center is attached to Plant in India and we secure excellent human resources there.
Therefore, we can supply a high-quality product at a low cost by a consistent system from process development to manufacturing in India.
We have already been stably supplying APIs and intermediates to the Japanese pharmaceutical companies.
Since Plant in India is located in the Technocrat Industrial Estate, Balanagar, Hyderabad, Telangana, it is easily accessible by train, land and air.
