One of the physical measures that can be used to reduce the volume of imports is the use of foreign exchange control. Foreign exchange controls are measures that a government can take to regulate the flow of foreign currency into and out of a country. By implementing foreign exchange controls, a government can limit the amount of foreign currency that can be used to purchase imports, which in turn can reduce the volume of imports. (reduction of personnel income tax) is not a physical measure that can be used to reduce the volume of imports because it is a fiscal measure that affects the disposable income of individuals, rather than a physical measure that directly impacts the flow of goods and services. (removal of imports duties) and (liberalization of credit for importers) are measures that can actually increase the volume of imports, rather than reduce it.
