Import of samples: customs treatment focuses on marketability assessment and procedural controls for sample consignments. Import of samples governs entry of specimens for demonstration, testing or market assessment by traders, representatives, research bodies and individuals. Commercial samples-from consumer goods to prototypes and machinery accessories-are differentiated from ordinary consignments and may arrive as personal baggage, port shipments or courier imports. Customs treatment focuses on assessing characteristics, usage and marketability to determine applicable formalities and documentation, balancing trade facilitation with necessary controls.
