The Institute was established in 1970 as an initiative of the Government of Trinidad and Tobago with financial and technical support from the United Nations Development Programme (UNDP) and United Nations Industrial Development Organization (UNIDO). It was incorporated under Act of Parliament no. 19 of 1971, which was subsequently amended by Act no. 33 of 1981. Although established with funding from the Government and the aforementioned international agencies, at the outset the Institute's mandate catered for the provision of services to the Caribbean region. Traditionally, the Institute's service base has been quite diverse, comprising the provision of laboratory-based analytical and engineering services (testing utilizing state-of-the-art, internationally accredited facilities), as well as associated consultancy support, training and applied Research and Development (primarily investigative/developmental work).
