The database, which is visible via the market access card online tool, contains information on tariff and non-tariff barriers in all active trade agreements, not limited to agreements officially notified to the WTO. It also documents data on non-preferential trade agreements (e.B Generalised System of Preferences systems). By 2019, the Market Access Card has provided downloadable links to textual agreements and their rules of origin.  The new version of the Market Access Card, to be published this year, will provide direct web links to relevant contract pages and connect to other ITC tools, in particular the Original Facilitator Guidelines. It is expected to become a versatile tool that helps businesses understand free trade agreements and qualify for origin requirements under these agreements.
