ATR Movement Certificate
An ATR movement certificate is a customs document used for trade between the EU and Turkey.
The customs arrangement with Turkey enables goods to qualify for reduced duty rates on provision of the original valid ATR movement certificate. This certificate also certifies that the goods with a specific shipment originate from Turkey.

EUR1 Movement Certificate
An EUR1 movement certificate is the main preference certificate for goods being imported from outside the EU and covers trade between many countries. The EUR1 is a recognised preferential certificate of origin. The original certificate must be stamped and authorised by the customs authority in the exporting country.
In some cases a declaration of origin on the commercial invoice can substitute the requirement for an original EUR1 certificate, if the total value of the goods is below a specified threshold.
