This is a tactic for limiting international trade as well as a defense or support for domestic customs duties. A tariff is a fee a government charges on goods and services imported from another nation in an effort to sway it. If the service is imported, the person or company who utilizes it is responsible for paying service tax. The importer of these services is therefore eligible to claim the tax credit. Contrary to imports, there is no tax on the exports of goods and services, which makes exports the tax-free alternative to imports.
There are two types of tariffs: fixed (a fixed amount per unit of imported products or a certain percentage of the price) and variable (the amount varies according to the price). People are less likely to purchase imported goods as a result of taxes because they become more expensive.
