Manufacture and wholesale trade of chemicals and rubber products, electrical equipment, paper and paper products, and printing and reproduction of recorded media are covered in this chapter. Regulatory barriers to competition are identified in the detergents and biocides industries, especially in terms of product trading (i.e. selling in bulk, prevention of umbrellabranding) and the licensing of manufacturing facilities. For cosmetics, products’ primary and secondary functions should be recognised by Greek legislation in line with EU guidance, helping suppliers and enhancing product mix. Abolishing excise duty on isopropyl alcohol would result in lower prices and in an increase of the competitiveness of Greek manufacturers that use it as a raw material. The alignment of the administrative registration and conformity marks of sockets and plugs will facilitate suppliers’ operations and enhance consumer protection. The cumulative effect of the recommendations will be to make markets more open and competitive, to the benefit of consumers.
