> This guidance from the Medicines and Healthcare products Regulatory Agency (MHRA) outlines the requirements for manufacturers and importers submitting notifications for e-cigarettes and refill containers in Great Britain. Operating under the Tobacco and Related Products Regulations 2016 (TRPR), the framework ensures that all vaping products meet strict safety and quality standards before entering the market. A primary focus of the guidance is the mandatory reporting of nicotine uptake levels. Companies are required to provide data demonstrating how nicotine is absorbed by users, typically through pharmacokinetic studies or robust comparative analysis. This testing ensures that devices deliver nicotine effectively without exceeding the legal concentration limit of 20mg/ml. Required actions for businesses include submitting comprehensive toxicological data and emission profiles via the MHRA portal. Failure to provide accurate nicotine uptake information or complying with the established safety thresholds constitutes a regulatory violation, preventing the legal sale of the product. The guidance serves as a compliance roadmap for the industry to maintain public health standards.
