To protect domestic businesses.

Let’s think of the USA and China:

If:

USA steel factories produces 1 steel girder and sells at $1000

Chinese steel factories produces 1 steel girder and sells at $500

- - If there is NO quotas, tariffs or other protectionisms, then the most rational thing is to purchase the Chinese steel girders. Harming USA steel factories.

- - If USA raises tariffs: Puts 50% tariff of Chinese steel

- Then Chinese steel, for USA consumers would cost $750. Lowering USA’s demand for Chinese steel but increasing USA consumer’s demand for USA steel.

They can increase the USA’s economic welfare as many domestic steel-extracting factories and their employee’s are protected/benefitted. Though, it may harm some manufacturing jobs.

Well, in the end it depends on the scale of those trade barriers.
