The R&D center set up in Nanjing has professional and experienced personnel, 6 of whom have Ph.D degree. So far SUT has been certified by CNAS, CMAF, CATL and GLP issued by OECD and has more than 300 employees in its lab-network of  Jiangsu, Shandong, Zhejiang, Inner Mongolia, Shanxi, and Shanghai. SUT is one of the few domestic organizations qualified in registration testing for export pesticides and also has the leading testing technique and market share in global honey and peanut supply chain management.

JSST GLP Test Facility was founded in May, 2013 and received the OECD GLP certificate issued by Germany BfR in November, 2014. We can conduct  physical and chmeical properties studyies and 5-batch analysis of pesticide in compliance with  OECD GLP Principles.
