(11)Article 12(3) and the first subparagraph of Article 23(3) of Regulation (EU) No 1151/2012 provide that for products originating in the Union that are marketed under a protected designation of origin, a protected geographical indication or a traditional speciality guaranteed, the Union symbols associated with those products have to appear on the labelling and that the relevant indications or abbreviations may appear on the labelling. The second subparagraph of Article 23(3) provides that the symbol is optional on the labelling of traditional specialities guaranteed produced outside the Union. Those provisions will only be applicable from 4 January 2016. However, Regulations (EC) No 509/2006 and (EC) No 510/2006, which were repealed by Regulation (EU) No 1151/2012, provided for the obligation to place on the labelling of products originating in the Union either the symbol or the complete indication and gave the option to use the indication ‘traditional speciality guaranteed’ on the labelling of traditional specialities guaranteed produced outside the Union. For the sake of continuity between the two repealed Regulations and Regulation (EU) No 1151/2012, the obligation of placing on the labelling of products originating in the Union either the Union symbols or the respective indication and the option to use the indication ‘traditional speciality guaranteed’ on the labelling of traditional specialities guaranteed produced outside the Union should be considered as implicitly set out by Regulation (EU) No 1151/2012 and already applicable. In order to ensure legal certainty and to protect the rights and the legitimate interests of producers or stakeholders concerned, the conditions of use of symbols and indications on the labelling as laid down in Regulations (EC) No 509/2006 and (EC) No 510/2006 should continue to be applied until 3 January 2016.
