Free-trade area

A free-trade area is the region encompassing a trade bloc whose member countries have signed a free-trade agreement (FTA). Such agreements involve cooperation between at least two countries to reduce trade barriers – import quotas and tariffs – and to increase trade of goods and services with each other. If people are also free to move between the countries, in addition to a free-trade agreement, it would also be considered an open border. It can be considered the second stage of economic integration.

Unlike a customs union (the third stage of economic integration), members of a free trade area do not have a common external tariff, which means they have different quotas and customs taxes, as well as other policies with respect to non-members. To avoid tariff evasion (through re-exportation) the countries use the system of certification of origin most commonly called rules of origin, where there is a requirement for the minimum extent of local material inputs and local transformations adding value to the goods. Only goods that meet these minimum requirements are entitled to the special treatment envisioned by the free trade area provisions.

"Cumulation" is the relationship between different FTAs regarding the rules of origin – sometimes different FTAs supplement each other, in other cases there is no cross-cumulation between the FTAs. A free-trade area is a result of a free-trade agreement (a form of trade pact) between two or more countries. Free-trade areas and agreements (FTAs) are cascadable to some degree – if some countries sign agreements to form a free-trade area and choose to negotiate together (either as a trade bloc or as a forum of individual members of their FTA) another free-trade agreement with another country (or countries) – then the new FTA will consist of the old FTA plus the new country (or countries).
