The SENT system in Poland: what it is, who it applies to and what it costs to get wrong
Who files the declaration and when, which goods are covered, why the reference number and geolocation matter, and what a mistake actually costs. Written from a forwarder’s desk, not from the statute.

What SENT is and who runs it
SENT is Poland’s electronic system for monitoring the carriage of so-called sensitive goods. It is run by the National Revenue Administration (KAS), and declarations are filed on the PUESC platform. The purpose is simple: the state wants to see what is moving, from where, to where and on which vehicle, in order to catch movements that avoid excise duty and VAT.
In practice it comes down to three things: the carriage must be declared before it starts, the driver must hold a reference number, and the vehicle must transmit position data. Missing any one of them is not a formality. It is grounds to stop the vehicle.
Who files what
The most common misconception is that the carrier files everything. Duties are split, and each party answers for its own stage.
| Party | What it does | When |
|---|---|---|
| Consignor | Files the declaration: goods, weight, route, consignee; receives the reference number | Before carriage begins |
| Carrier | Adds vehicle and driver data, switches on position reporting | Before departure |
| Consignee | Confirms receipt of the goods in the system | After delivery |
If any link fails to close its step, the declaration stays open, and that is visible on the KAS side.
Which goods are covered
- Fuels and energy carriers - petrol, diesel, lubricating and technical oils, LPG.
- Alcohol, including denatured alcohol used in industry.
- Raw tobacco and tobacco products.
- Chemicals - solvents, thinners, certain medicinal products.
- Waste, including hazardous waste and some secondary raw materials.
The list is built on CN codes and is updated from time to time, so learning it by heart is pointless. The working rule: if the cargo touches excise duty or waste in any way, check the CN code on PUESC before loading. That includes chemicals and hazardous materials and movements handled under customs compliance.
Reference number and geolocation
The reference number identifies the specific movement. The driver must carry it and quote it during an inspection, on a phone is fine, but it has to be available immediately, not after a call to the office.
Position data is transmitted either by a locator in the vehicle or by an app on the driver’s phone. The system compares the actual route against the declared one. A discrepancy is not a penalty in itself, but it is the signal that gets the vehicle pulled over.
A change of route, a transhipment, a change of consignee, each of these is updated in the declaration before it happens, not afterwards.
Penalties, how much and for what
| Breach | Consequence |
|---|---|
| Carriage not declared | Financial penalty, typically PLN 5,000–20,000 depending on the party and the breach |
| Data not matching reality (goods, weight, route) | Penalty plus detention of the shipment pending clarification |
| Driver without the reference number | Fine for the driver, vehicle stopped |
| Locator switched off or not working | Penalty; the movement counts as unmonitored |
| Serious or repeated breaches | Seizure of goods and vehicle pending clarification |
Exact amounts come from the Act on the monitoring of the carriage of goods and differ for consignor, carrier and driver. The rules have changed several times, check the current wording before the movement.
Five mistakes that most often end in a penalty
- Assuming transit does not count. It does. Transit through Poland is declared exactly like a domestic movement.
- Forgetting cabotage. Cabotage inside Poland also requires a declaration, even on foreign plates.
- Rounded weight. “About 20 tonnes” is not a figure for a declaration. A mismatch between the document and the weighbridge is one of the most common reasons for a penalty.
- Route change without an update. A detour around a jam is understandable; an undeclared detour with a transhipment is not.
- Unconfirmed delivery. The declaration stays open and the exposure sits with every party.
How we handle it
On SENT-covered movements the declaration and the reference number are part of the order, not a paid extra. We check the CN code before loading, keep the declaration updated when the route changes, and close it after delivery. The same applies to ADR movements. Destinations are listed under road freight.
Frequently asked
Does SENT apply to every shipment?
No. Only to goods on the CN-code list. Everything else sits outside the system.
Who pays the penalty if the declaration was missing?
It depends whose duty was not performed. Consignor, carrier and consignee each answer for their own stage, and more than one party can be hit.
Does the declaration expire?
Yes, the reference number is valid for a limited period. If the movement slips, the declaration has to be updated.
Is a dedicated locator required?
Not always, an app on the driver’s phone is acceptable. The one condition is that the data must flow without gaps.
