Customs clearance for postal and courier consignments: duties assessed and collected before delivery under expedited regulatory procedures. Customs coordinates with postal authorities to grant clearances after selective checks; post consignments not qualifying as free gifts or samples are assessed for duties, which are communicated to postal authorities and collected before delivery. Courier imports and exports operate under a regulatory framework enabling expedited electronic clearance and may be handled at dedicated courier terminals staffed by Customs officers, subject to duty discharge.
