Any company selling e-liquids and short-fills in the UK must notify the National Poisons Information Service (NPIS) about their products and provide NEW updated Safety Data Sheets (SDS).
In December 2018, there was a change to Classification, Labelling and Packaging (CLP) for nicotine. The information contained in the data sheets altered too. If your company has sheets that pre-dates December 2018, new ones are required.
To comply, companies must send a list of their products and SDS for each SKU to the NPIS at email@example.com.
