1. Overview: Border checks on fuel tourists (2026)
In 2026 the German customs authority (Zoll) intensified controls at the borders with Poland and the Czech Republic to monitor so-called fuel tourists—drivers who cross the border to fill up where petrol and diesel are significantly cheaper. While premium petrol in Germany costs over €2.00 per liter, prices in the Czech Republic are around €1.67 per liter and in Poland can be 30 to 65 cents lower. The measures aim to enforce import rules and prevent unreported commercial fuel imports.
2. What customs can check at crossings
Customs controls at border crossings focus on identifying fuel quantities that exceed what is permitted for private use. Authorities carry out stichprobenartige (spot) and targeted controls to determine whether transported fuel falls within private allowances or constitutes commercial import.
- Visual inspections of vehicle fuel tanks and additional containers
- Questions to drivers about purchase location and quantities
- Use of technical aids and equipment to support checks
3. Legal limits for private fuel imports
Under the current enforcement approach, private individuals are permitted to bring into Germany the amount of fuel that fits in their vehicle’s tank plus one additional reserve canister of up to 20 liters of the same fuel. Quantities beyond that are treated as commercial imports and must be declared and taxed.
| Situation | Rule |
|---|---|
| Fuel in vehicle tank only | Permitted for private import |
| Fuel in tank + one reserve canister (up to 20 L) | Permitted for private import |
| Any additional fuel beyond the above | Considered commercial import; must be declared and taxed |
4. Consequences if limits are exceeded
If fuel quantities exceed the private-import limits, the import is classed as commercial and must be subject to customs clearance and taxation. Failure to declare and pay required duties can lead to fines or seizure of the fuel by customs authorities.
5. How and where controls take place
Controls are conducted in a targeted and random manner at selected border crossings. The customs checks are concentrated in regions with high cross-border traffic for cheaper fuel.
5.1 Regions and hotspots
The intensified checks have been reported at crossings in Brandenburg, Saxony and Bavaria, where customs officers perform spot checks and targeted inspections to enforce import rules.
- Brandenburg: border points with Poland
- Saxony: crossings to both Poland and the Czech Republic
- Bavaria: crossings to the Czech Republic
6. Why price differences exist
Price gaps between Germany and neighboring countries are driven largely by tax differences. In Germany, motorists face high levies on fuel, including an energy tax of 65.45 cents per liter of petrol plus an additional CO2 charge. Critics point out that these high taxes contribute to markedly higher pump prices in Germany compared with the Czech Republic and Poland.
Some observers also criticize the approach as selective border control: they argue it treats border permeability differently depending on the issue at hand, while the high German tax burden remains a core cause of cross-border fuel purchases.
7. Practical summary and key takeaways
Key points to remember when crossing the border with fuel in 2026:
- Private import is limited to the amount in your vehicle’s tank plus one reserve canister up to 20 liters of the same fuel.
- Amounts above that are treated as commercial imports and must be declared and taxed; otherwise fines or seizure can follow.
- Controls are stichprobenartig (spot) and targeted at selected crossings, particularly in Brandenburg, Saxony and Bavaria.
- Customs use visual checks, questioning and technical aids during inspections.
- Price differences are largely due to tax levels in Germany, including an energy tax of 65.45 cents per liter and an additional CO2 charge; neighboring countries often have lower pump prices.
