Do you know what your obligations are, if your mixtures are produced and labelled as private-label products before 1 June 2015?
When you buy a private label product from a manufacturer, the product is considered as marketed when the ownership switches from the manufacturer to you. Therefore you can market the product with the old labelling as long as you owned the product before 1 June 2015.
Between 1 June 2015 and 1 June 2017 the product can be sold further down the supply chain with labelling according to the old legislation as long as no changes at all are made to the label or the packaging. From 1 June 2017 all labels must be according to CLP.
