Trade barrier is the government's p

Trade barrier is the government's policy to restrict international trade and import. Trade barriers either make brand trading more difficult or hinder trade. Generally speaking, trade barriers are divided into tariff barriers and non-tariff barriers. The so-called non-tariff barrier refers to the trade barrier formed by the customs of a country when the import and export commodities pass through its customs territory and the tariffs levied by the importers and exporters of that country. The so-called non-tariff barriers refer to all import restrictions except tariffs, such as import quota system, import license system, foreign exchange control and harsh technical standards.
