In accordance with the provisions of the Treaty of Asuncion and as an essential condition for the deepening of the integration process, MERCOSUR Common External Tariff (AEC) has been in effect since 1995.
MERCOSUR Origin Regime (ROM) is a Preferential Regime constituted by the set of requirements and procedures agreed by the States Parties to determine whether or not a product qualifies for the granting of preferential treatment established by MERCOSUR agreements, which includes the elimination of tariffs on intra-regional trade.
MERCOSUR Common Nomenclature (NCM) is based on the Harmonized Commodity Description and Coding System developed by the World Customs Organization (WCO). The NCM adopts WCO tariff subheadings (six digits) and adds two more digits to provide a greater level of detail, resulting in eight-digit codes.
