There are three types of importers: 1. Established importers imported goods during a basic period and can apply for a quota certificate specifying the quantity and value of goods they can import, providing documentation of past imports. 2. Actual importers import goods for their own industrial use and must obtain a license through a sponsoring authority certifying their requirements. 3. Registered importers importing under export promotion schemes obtain licenses from the Chief Controller of Exports and Imports.
