customs union
C1Formal / Technical
Definition
Meaning
A group of countries that have agreed to abolish tariffs and other trade barriers on goods moving between them and adopt a common external tariff on imports from non-member countries.
A type of trade bloc and a key stage of economic integration. It involves not only a free trade area with no internal barriers but also a unified commercial policy toward the rest of the world. This requires the establishment of common external tariffs and often leads to common trade negotiations.
Linguistics
Semantic Notes
A customs union is distinct from a simple 'free trade area' due to the common external tariff. It often forms the foundation for deeper economic integration like a 'single market' or 'economic union'.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'таможенный союз' – this is a direct translation and correct, but Russian speakers might associate it specifically with the Eurasian Customs Union, limiting the general concept.
Common Mistakes
- Using 'customs union' interchangeably with 'free trade agreement'. The latter lacks the common external tariff.
- Incorrect pluralisation: 'customs unions' is correct for multiple such entities.

FAQ
Frequently Asked Questions
To boost trade between member states by removing internal tariffs and to strengthen their collective trade negotiating power by presenting a unified external tariff.
No, not independently on goods. A core principle is a common commercial policy, meaning trade deals with non-members are negotiated collectively by the union.
Yes, the EU is a customs union, but it is also much more (a single market with free movement of goods, services, capital, and people). The customs union is one of its foundational pillars.
A customs union deals primarily with tariffs on goods. A single market goes further, removing non-tariff barriers (like differing regulations) and often includes free movement of people, services, and capital.
