Resolution CM/Res(201X) Y, its Guiding Principles and the supplementary Technical Guides contribute 22 to the protection of human health by ensuring the safety and quality of food contact materials and articles 23 as defined in Regulation (EC) No 1935/2004, that are not covered by material specific legal provisions or other measures at the European Union (EU) level. The Resolution therefore complements the existing 25 European legislation. This appendix provides general guidance, e.g. on the use of substances in the manufacture of food contact materials and articles, labelling and the need for a declaration of compliance and supporting compliance documentation. It applies to all food contact materials and articles under the scope of the Resolution and to the container-closure-system of medicinal products in cases considered appropriate by the competent authority responsible for granting their marketing authorisation. The supplementing Technical Guides detail the specific implementing provisions and further restrictions for the materials and articles under their scope.
