International trade involves commercial transactions between people and businesses from different countries. While such business goes on all the time, nevertheless there are often a series of potential hurdles to cover before deals can proceed. One major aspect of international trade involves the laws related to tariffs, dumping and countervailing duties. This all involves the rules by which particular products may enter a particular country. Another major aspect to this area of law and business involves treaties, conventions and accords between nations that might impact the transaction. A third major element involves the often complex business negotiations between parties.
