Because the economy of a certain country relies heavily on steel production, its government only allows a set amount of foreign steel to be brought into the country each year. What type of barrier to trade is this an example of?

import quota

Explanation:

The import quota is a trade barrier established to benefit local producers of a given product. This barrier restricts the quantity of a given foreign product in a country that produces that product. The objective, as already mentioned, was to reduce the circulation of foreign products, benefiting the purchase of local products and stimulating the economy and local production. This trade barrier is temporary and can be established for long or short periods of time.

An example of this can occur when the US government imposes import quotas on Brazilian sugar, to stimulate the production and sale of local sugar.
