Courier clearance procedures enable simplified customs processing with authorised couriers responsible for duties and selective scrutiny. Customs clearance of imports and exports by courier creates a fast track regime where registered Authorised Couriers perform clearance under either manual or electronic regulations, with minimal parcel examination and selective document scrutiny; couriers typically pay any leviable duty on behalf of consignors before delivery and must file the Courier Import Manifest, while courier operations remain governed by applicable trade and statutory law.
