A revised version of the Dutch Commodities Regulation of Food Packaging and Consumer Products (Warenwetregeling verpakkingen en gebruiksartikelen) is to come into force on 1 April 2014. There are elements of the regulation relevant to producers of nano-form substances.
The regulation will not apply to packages or consumer goods lawfully produced or marketed in EU Member States, and will not cover materials and substances already covered by existing EU legislation; nano-form substances can therefore be used if the end product remains in compliance with Article 3 of EC Regulation No. 1935/2004. A list of other substances not contained within EC regulations is given by the decree, but the text specifically says that these rules do not apply to nano-form versions of those substances.
The Netherlands brought about this revision in order to both avoid overlap with existing EU regulations, and to cover materials and articles excluded from them. Although no transitional date is provided by the text, it states that the changes are not expected to affect business.
