Transportation across Poland and transit through the country are important routes for Ukrainian and European logistics companies. One of the key tools of government control in this area is the SENT system (System Elektronicznego Nadzoru Transportu). It is designed to monitor the movement of certain categories of goods to prevent illegal transport and reduce the shadow economy.
What is the SENT system?
The SENT system is an electronic registry that records data about the transportation of “sensitive” goods. This includes items that are often involved in violations of tax or customs regulations.
Such goods include:
- fuel (diesel, gasoline, gas);
- alcohol and tobacco products;
- chemical substances;
- certain types of food products (for example, oil, sugar, coffee, meat);
- other goods with increased tax risks.
Each shipment must be registered in the system, and the vehicle must be equipped with a GPS tracker or monitoring system that allows real-time tracking.
Who must register shipments in SENT?
The following parties are required to submit data to the system:
- the sender (shipper in Poland or abroad);
- the recipient (if the shipment is headed to Poland);
- the carrier (the transport company).
This means that responsibility is shared among all participants in the process.
How does the registration process work?
To transport goods controlled under the SENT system, it is not enough to simply prepare the documents for the cargo and vehicle. Each party — the sender, recipient, and carrier — must complete their part of the electronic registration process. This procedure allows the Polish authorities to monitor the movement of goods in real time and ensures full transparency of transportation.
- Creating a notification — the sender or recipient enters data about the cargo, route, and vehicle.
- Carrier confirmation — the transport company confirms the data and provides details about the driver, vehicle, and trailer number.
- Movement monitoring — the vehicle must transmit its geolocation. For this purpose, carriers use M2M SIM cards installed in GPS trackers.
- Completing the transport — after delivery, the recipient closes the record in the system.

Penalties for violations
Polish authorities strictly monitor compliance with SENT regulations. Fines may reach:
- up to 46,000 PLN for missing registration;
- up to 20,000 PLN for incorrect or false data;
- up to 10,000 PLN for lack of GPS tracking.
That’s why it’s extremely important for transport companies to use reliable tracking solutions.
The role of M2M SIM cards in the SENT system
The system requires stable data transmission to ensure accurate vehicle tracking. The most efficient solution is the use of international M2M SIM cards:
- operate across all EU countries without roaming restrictions;
- provide uninterrupted data transmission;
- automatically switch between networks of different operators;
- reduce communication costs during international transport.
Why businesses should comply with the SENT system
If your company operates in international transportation or forwarding, understanding and properly using the SENT system helps you:
- avoid fines and delays;
- guarantee the legality of shipments to your clients;
- speed up customs and control procedures in Poland;
- strengthen your company’s reputation as a reliable partner.
