Courier clearance procedure permits fast-track import export with authorised couriers and simplified examination, subject to applicable trade laws. Courier import and export clearances operate under separate manual and electronic regulatory regimes, limited to registered Authorised Couriers. The scheme provides fast track processing with minimal parcel examination and selective document scrutiny; courier companies pay any leviable duty on behalf of importers/exporters before delivery. Both air and other transport modes may be used, Courier Import Manifests are filed at airports and Land Customs Stations, and the regime remains subject to the applicable trade and customs laws.
