Trade barriers elude fixed definitions, but may be broadly defined as government laws, regulations, policies, or practices that either protect domestic goods and services from foreign competition, artificially stimulate exports of particular domestic goods and services, or fail to provide adequate and effective protection of intellectual property rights. The 2013 National Trade Estimate Report on Foreign Trade Barriers (NTE) is the 28th in an annual series that surveys significant foreign barriers to U.S. exports. This book provides an overview of this report which estimates the impact of foreign practices on the value of U.S. exports. Information is also included on some of the actions taken to eliminate foreign trade barriers. Opening markets for American goods and services, either through negotiating trade agreements or through results-oriented enforcement actions, is the Obama Administration's top trade priority. This book is an important tool for identifying trade barriers and classifies these barriers into nine different categories. These categories cover government-imposed measures and policies that restrict, prevent, or impede the international exchange of goods and services.
