What is an EUR1 Certificate?

An EUR.1 certificate (movement certificate EUR.1) proves the origin of goods so they can be imported at a reduced or zero tariff under a preferential trade agreement between the EU and a partner country.

What the EUR.1 certificate does

Preferential (lower or nil) duty only applies to goods that genuinely originate in a country the EU has a trade agreement with, such as the EFTA states, the Western Balkans and many other free-trade or association partners. The EUR.1, issued by customs in the exporting country, is the proof of that origin. Without it, the standard third-country tariff applies.

EUR.1, ATR and REX

For EU-Turkey trade, the customs-union equivalent is the ATR certificate. Under the EU's Generalised System of Preferences, registered exporters instead self-certify origin through the REX system. Which proof applies depends on the country and the agreement in force.
