Final answer:
Customs procedures in many countries often discriminate against imports and favor exports through policies such as tariffs and nontariff barriers to restrict imports and promote domestic trade.
Step-by-step explanation:
Customs procedures in many countries often discriminate against imports and favor exports. This means that these countries implement policies and regulations that make it more difficult or costly to import goods, while providing advantages or benefits to their own exporting industries. These policies can include the use of tariffs, nontariff barriers, and other protectionist measures to restrict imports and promote domestic production and trade.
