YONSUNG's highest priority is the top quality of APIs. We manufacture APIs in accordance with ICH Guidelines (Q7) and export to the US, EU, Japan and other countries. YONSUNG continuously monitors new requirements from the FDA, ICH, EMEA and WHO. Stringent controls are built-in to ensure that every single product meets and exceeds the specifications of the most well known pharmacopoeia as well as our customer's individual requirements. YONSUNG is fully approved by USFDA, European and Japanese authorities for the development and manufacture of APIs.

In partnership with leading pharmaceutical companies throughout the world, YONSUNG is ready to develop a successful and enduring relationship with your R&D, manufacturing and regulatory teams.
