Poland is a founding member of the World Trade Organization. As a member of the European Union, it applies the common external tariff to goods from other countries including the United States. Poland's major imports are capital goods needed for industrial retooling and for manufacturing inputs. The country's exports also include machinery but are highly diversified. The most successful exports are furniture, foods, motor boats, light planes, hardwood products, casual clothing, shoes and cosmetics. Germany is by far the biggest importer of Poland's exports as of 2013. In the agricultural sector, the biggest money-makers abroad include smoked and fresh fish, fine chocolate, and dairy products, meats and specialty breads, with the exchange rate conducive to export growth. Food exports amounted to 62 billion złoty in 2011, increasing by 17% from 2010. Most Polish exports to the U.S. receive tariff benefits under the Generalized System of Preferences (GSP) program. Poland ranks in the top 20 in the world both in terms of exports and imports, recording a clear trade surplus.
