As part of his supervision on various government departments, Raisi toured the exhibition as part of a visit to Iranian Presidency's Deputyship for Science and Technology on Monday.
The fair showcases more than 2,000 knowledge-based products in different sectors such as agriculture machinery, transport, water and energy, smart homes, electricity, laboratory equipment and medicines.
Nearly 690 companies are exhibiting their products in an area of 3,500 square meters.
The iHiT headquarters is located at Tehran International Exhibition Center and acts as a hub for export of Iran's science and technology products.
Branches of iHiT have already been established in countries like Kenya, Syria, China, and Russia, Uzbekistan, Turkiye and Iraq.
The center has been established with the aim of promoting hardware infrastructure as well as trading and exporting knowledge-based technologies. One of its important missions is to introduce the capabilities of Iranian knowledge-based companies to international markets.
Almost 9,600 knowledge-based companies are currently active across Iran, which have created 328,479 jobs in the current Iranian calendar year that ends on March 20, 2024.
That comes as the companies have exported some $1,890 million worth of products over the same period.
