The Notification of TPD obliges manufacturers and importers to transmit to the Member States a wide range of information, from the formulation to commercial and production data, passing through toxicological dossiers of each ingredient and specific chemical analysis, with a particular attention to nicotine.
The submitter declares the conformity of the products with regard to the safety criteria established by the legislation. A notified product is not automatically authorized for sale, but rather exposes the notifier to the verification of what has been communicated to the authorities: Member States reserve six months from receipt of the notification to study the relative dossier, with particular attention to the danger of the products.
Before marketing the product, it is necessary to wait until the end of these six months period or, in some Member States, till the receipt of a communication from the competent Authorities.
Individual Member States may require fees for receiving, storing and managing the notified data and also for their annual update.
