Why countries import goods?

Answer

countries import goods, because one country can't make everything that is needed to support its people.

Countries import goods because they are harder, more expensive or impossible to make inside their country.

Japan imports oil, as an example, because they do not have any inside their country. The U.S.A. imports semiconductors because our laws make semiconductor manufacture very expensive.

Answer

Imports, along with exports, form the basis of international trade. A country has demand for an import when domestic quantity demanded exceeds domestic quantity supplied, or when the price of the good (or service) on the world market is less than the price on the domestic market.
