The Registered Exporter system

The Registered Exporter system (the REX system) is the system of certification of origin of goods that will be applied in the Generalised System of Preference (GSP) of the European Union as from 1 January 2017. It is based on a principle of self-certification by economic operators who will make out themselves so-called statements on origin. To be entitled to make out a statement on origin, an economic operator will have to be registered in a database by his competent authorities. The economic operator will become a "registered exporter". The REX system is the term used to designate the system of certification of origin as a whole, and not only the underlying IT system which is used for the registration of exporters.
