The International Engineering Sourcing Show (IESS) is a leading trade fair in the field of mechanical engineering and is one of the most significant events of its kind in India. It is held annually in March and had its premiere in 2012 in Mumbai. The fair is organized by the Engineering Export Promotion Council (EEPC) of India, which is dedicated to promoting mechanical engineering and engineering sciences in the country. IESS has established itself as the largest mechanical engineering fair in India and plays a central role in promoting new technologies and investments in the sector. It provides a platform for traders, manufacturers, and service providers from the engineering sector to represent the entire value chain. The fair brings together not only businesspeople but also representatives from the economy, associations, academia, and government agencies, all contributing positively to the market. The fair's thematic diversity is extensive, covering areas such as subcontracting and subcontractorship, metalworking and workshops, industrial machinery and equipment, energy, electrical engineering, as well as innovation and technology. This diversity reflects the dynamic nature of the engineering sector and offers participants a comprehensive insight into current trends and developments. Annually, the fair attracts thousands of visitors and exhibitors from around the world and is renowned for its excellent networking opportunities, innovative exhibitions, and an extensive conference program. The IESS serves not only as a fair but also as a significant forum for the exchange of ideas, promotion of trade relationships, and presentation of the latest developments and innovations in the engineering sector. The International Engineering Sourcing Show (IESS) takes place irregularly, and therefore for the thirteenth time previsibly in February 2026 in Chennai.
