Customs regulations in Belgium are in place to ensure the orderly flow of goods across borders while safeguarding public safety, national security, and economic interests. Goods may be seized at borders for various reasons, including the presence of prohibited items, incomplete or inaccurate documentation, and non-compliance with import/export regulations. Belgium’s customs agency, Het Agentschap voor Douane en Monopolies, plays a crucial role in enforcing these regulations to maintain the integrity of the customs process.
