Customs clearance procedures require Bills of Entry or Shipping Bills, documentary verification and risk based physical examination before release. Customs clearance requires submission of a Bill of Entry for imports and a Shipping Bill for exports, with declarations (description, value, quantity, tariff heading, exemptions) verified under a self-assessment scheme. Documentary scrutiny is standard; physical examination is conducted based on facilitation levels set by the Risk Management System. Absent discrepancies, an Out of Charge order (imports) or Let Export Order (exports) is issued to permit release; inaccuracies permit reassessment and corrective Customs action.
