The traceability system for tobacco products

In short, the traceability system means that all economic operators, facilities and machines that are part of the supply chain of tobacco products have a unique identification code. All tobacco products have a unique identity label, also called a traceability label. The purpose of the traceability system is to combat illegal trade in tobacco products.

Unique identifier - a traceability marking

All unit packets of tobacco products must carry a unique identifier (UI), also known as a traceability marking. When the unit packet is handled and transported, the events shall be recorded and the information transferred to a central database. The financial transactions linked to the tobacco product are also recorded in the database.

A tobacco product may not be sold if it does not have the UI. Identifier codes, UIs and corresponding human-readable codes are generated and issued by the competent ID issuer.
