The Siicex web site is intended to offer organizations, businesses, importers, exporters, government, students and citizens information related to foreign trade from a single enquiry point, enabling them to reduce transaction costs by facilitating information searches and providing certainty about their obligations in acts of Foreign Trade.

Its purpose is to present the regulations which establish the general provisions within the scope of competence of the Secretariat, and the criteria for compliance with laws, international trade agreements or treaties, decrees, regulations and other regulatory systems, grouping them so users can apply them easily.

The system comprises five sections: Siiceteca (Virtual Library); Tariff; Foreign Trade Bulletin, Today; Did you know…? and This Month, which together seek to give users easy access to information related to foreign trade.
