The track and trace system for tobacco products is a key part of the European Union's Tobacco Products Directive -TPD. This system was introduced to combat the illegal trade in tobacco products and to ensure that all products on the market are legal and meet the standards set. Here are the main elements of this system:

• Unique identifier: Each tobacco package must have a unique identifier that allows it to be tracked from the manufacturer to the retail store.
• Central database: All information on the movement of tobacco products is stored in a central database that can be used by control authorities to monitor and verify the legality of products.
• Transaction Records: Manufacturers, importers, and distributors are required to keep detailed records of all transactions involving tobacco products, allowing for traceability and verification of the origin of the products.
• Mandatory registration: All entities involved in the tobacco supply chain must be registered and approved by the competent authorities.
• Regular audits: The system is regularly reviewed and audited to ensure its effectiveness and to detect any deficiencies or attempts to circumvent the rules.

This track and trace system is designed to enhance transparency and accountability throughout the supply chain of tobacco products, thereby reducing the risk of illegal trade and protecting consumers' health.
