Non-tariff barriers

Non-tariff barriers to trade (NTBs; also called non-tariff measures, NTMs) are trade barriers that restrict imports or exports of goods or services through measures other than the imposition of tariffs. Such barriers are subject to controversy and debate, as they may comply with international rules on trade yet serve protectionist purposes. Sometimes, uniformly applied rules of trade may be more burdensome to some countries than others, e.g. for countries with developing economies.
