Currently, the ASEAN Merchandise Trade Agreement (ATIGA) – ASEAN`s main agreement on reducing regional tariffs – contains a number of criteria used to determine the country of origin of a commodity, as well as guidelines for determining whether certain products receive preferential tariff treatment.
