/ˈkʌstəmz ˈjuːnjən/ – Phrase
Definition: liên hiệp hải quan.
A more thorough explanation: A customs union is an agreement between two or more countries to remove trade barriers, such as tariffs and quotas, between themselves and to adopt a common external trade policy towards non-member countries. Members of a customs union also typically agree to apply common tariffs to goods imported from outside the union.
Example: The European Union (EU) is a prominent example of a customs union. Member states have abolished internal tariffs and quotas, allowing goods to flow freely within the bloc. However, they maintain a common external tariff for imports from countries outside the EU.
