Together, these agreements mean that about half of all goods entering the United States enter duty-free, according to the government. The average import duty on industrial products is 2%. In the modern world, free trade policy is often implemented by a formal and reciprocal agreement between the nations concerned. However, a free trade policy may simply be the absence of trade restrictions. A trade agreement signed between more than two parties (usually neighbouring or in the same region) is considered multilateral. They face the main obstacles – to content negotiation and implementation. The more countries involved, the more difficult it is to achieve mutual satisfaction.

It should be noted that with regard to the qualification of the original criteria, there is a difference in treatment between inputs originating and outside a free trade agreement.
Inputs originating from a foreign party are normally considered to originate from the other party when they are included in the manufacturing process of that other party. Sometimes the production costs generated by one party are also considered to be those of another party. Preferential rules of origin generally provide for such a difference in treatment in determining accumulation or accumulation. This clause also explains the impact of a free trade agreement on the creation and diversion of trade, since a party to a free trade agreement is encouraged to use inputs from another party to allow its products to originate.  As a general rule, the benefits and obligations of trade agreements apply only to their signatories.
