Voluntary detention agreements and ordered marketing agreements are considered grey zone measures and have been banned by the World Trade Organization since 1995. All grey area measures in operation at the time were discontinued in 1999.  Ordered marketing agreements also address the difference between binding and non-binding agreements. Ordered marketing agreements are included in self-limitation agreements; However, voluntary retention agreements may also cover trade agreements between industries and governments. The Consumers` Union distinguishes the binding nature of the non-binding government for industrial agreements and the state regime. The impact on national and international law varies according to binding and non-binding agreements. An agreement could create problems with domestic law, but not with international law or vice versa. As a result of the increasing pressure exerted by the constant evolution of import patterns and world trade, the desire for orderly marketing agreements has increased, which has led to the making of orderly marketing agreements a political instrument. If no agreement is negotiated, the importing country will be able to pursue a more unilateral trade policy.  An orderly marketing agreement is a non-legal contract entered into by the national government, which stipulates that a sovereign state must refrain from exporting goods to a targeted sovereign state. These agreements relate directly to voluntary export restrictions, safeguard clauses and leakage clauses. Ordered marketing agreements are primarily bilateral agreements between the governments of two countries and any changes to the agreement must be approved by both parties.
 Only the United States has orderly marketing agreements for imports of textiles, steel, automobiles, electronics and footwear.  In the late 1960s and early 1970s, a marketing agreement was reached in the steel industry. This agreement came when the U.S. government called on the steel industry, mainly from Japan and Europe. This is the idea of self-limiting steel products in the U.S. market. During this period, a letter from the Japanese and European steel industry was sent to the United States to present the action plan.
