The interpretative notice is not new legislation, it clarifies certain elements linked to the interpretation and the effective implementation of existing EU legislation. It aims to provide Member States, economic operators and consumers with the necessary information on the indication of origin of products when it comes to products originating in Israeli settlements beyond Israel’s 1967 borders.
In a nutshell, the interpretative notice recalls that when the indication of origin is mandatory, i.e. explicitly required by the relevant provisions of EU law, it must be correct and not misleading. When the indication of origin is not mandatory but it is provided on a voluntary basis, the information must also be correct and not mislead the consumer.
