The Vietnamese word "ải quan" refers to "customs" in English, specifically the government agency or authority that regulates the import and export of goods across borders. It can also refer to the processes and procedures involved in checking goods at a border, ensuring that they comply with the law and that any applicable duties and taxes are paid.
Basic: "Khi tôi đến sân bay, tôi phải đi qua ải quan."
(When I arrived at the airport, I had to go through customs.)
Advanced: "Hàng hóa của tôi đã bị giữ lại bởi ải quan vì không có giấy tờ hợp lệ."
(My goods were held by customs because they did not have the proper documentation.)
While "ải quan" primarily refers to customs in the context of trade and travel, it can also imply the act of customs clearance, which is the process of passing goods through customs.
When traveling internationally or shipping goods, it’s important to understand the rules and regulations of customs to avoid delays or fines.
