8.7.2004 Official Journal of the European Union L 23721 (Acts whose publication is not obligatory) COMMISSION COMMISSION DECISION of 1 July 2004 establishing a transitional measure for the implementation of Regulation (EC) No 998/2003 on the animal health requirements applicable to the non-commercial movement of pet animals (notified under document number C(2004) 2365) (Text with EEA relevance) (2004/539/EC) THE COMMISSION OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Community, Having regard to the Regulation (EC) No 998/2003 of the European Parliament and of the Council of 26 May 2003 on the animal health requirements applicable to the non- commercial movement of pet animals and amending Council Directive 92/65/EEC (), and in particular Article 21 thereof, Whereas: () Regulation (EC) No 998/2003 establishing veterinary conditions  applicable to  the non-commercial movements of pet animals, is to apply from 3 July 2004. Despite measures which have been adopted to ease the transition from the existing conditions to those estab- (*) OJ L 146, 13.6.2003, p. 1. Regulation as amended by Commission Regulation (EC) No 592/2004 (O] L 94, 31.3.2004, p. 7). lished by Regulation (EC) No 9982003, its implemen- tation requires in particular the availability of the passport document in all the veterinary offices, the issuing of new models of import certificates for entry from third countries, and post-vaccination testing for animals from third countries not listed in Part C of Annex II to Regulation (EC) No 998/2003. It appears that in spite of the efforts undertaken by Member States some uncertainties remain with regard to those conditions, in particular taking into account the considerable number of people about to travel with their pet at this period of the year for summer holidays. Consequently, the annual peak in pet movements could result in numerous administrative difficulties. It is therefore advisable to maintain as necessary the application of the national conditions currently in force for a sufficient period of time. As a consequence, during this period movements shall be allowed in conformity either with Regulation (EC) No 998/2003 or with national rules which were in force before 3 July 2004. Accordingly, the derogation from Commission Decisions 2003/803/EC (%) and 2004/203/EC (}), provided for in Commission Decision 2004/301/EC, as regards the format for certificates and passports to be used for the non-commercial movement of dogs, cats and ferrets should be postponed.
