As NI follows the EU Cosmetics Regulation, you may be classed as an importer or as a distributor under the UK Cosmetics Regulation. Please check:
If the brand’s RP is located in an EU/EEA country and have appointed a UK RP, you are likely to be classed as an importer. However, you are strongly advised to liaise with the brand’s UK RP and arrange for a mandate, to shift your importer responsibilities to the designated RP. In this way, you can be a distributor; as such, you have obligations under Article 6 of the UK Cosmetics Regulation. For more information, please check paragraphs 30-33 of the UK Government guidance for cosmetic products.
