The Act No. 5 of 1968 - External Trade Act grants the Minister authority, under Art. 5, to regulate the export of goods through orders published in the Gazette. These orders may prohibit exports without a licence, impose restrictions, or set conditions for exportation. Such orders take effect upon publication and automatically cancel previously issued licences, requiring the Permanent Secretary to issue new licences in compliance with the updated provisions.
Art. 6 empowers the Permanent Secretary to issue licences for export-restricted goods, provided the export does not undermine any trade agreements or arrangements related to internal or external trade or currency approved by the Government. Licences are denied if the export poses risks to these agreements or arrangements.
As of 2023, these requirements only apply to radio and television transmitting equipment, whose exports are allowed only with a licence from the Minister of Communications.
