An import is any good (e.g. a commodity) or service brought in from one country to another country in a legitimate fashion, typically for use in trade. It is a good that is brought in from another country for sale. like a country gives supplies to another country. Which means that they are exporting something. Import goods or services are provided to domestic consumers by foreign producers. An import in the receiving country is an export to the sending country.
Imports, along with exports, form the basis of international trade. Import of goods normally requires involvement of the customs authorities in both the country of import and the country of export and are often subject to import quotas, tariffs and trade agreements. When the "imports" are the set of goods and services imported, "Imports" also means the economic value of all goods and services that are imported. The macroeconomic variable I usually stands for the value of these imports over a given period of time, usually one year.
