Hong Kong is a free port: no customs tariff is charged on the import or the export of goods. The Trade and Industry Department puts it directly: “Hong Kong is a free port. We pursue a free trade policy and do not maintain barriers on trade. No tariff is charged on import or export of goods.” The absence of a tariff is not the absence of obligation: almost every import and export requires a declaration within 14 days, four categories of goods bear excise duty, and dozens of categories require a licence.
