Polish companies can also be subject to fines.

Polish companies can also be subject to fines. And the reason is quite obvious - they do not check the contacts of the contractor, the goods being transported, etc. Therefore, it is not surprising that some companies, perhaps without knowing it themselves, are still working with the aggressor countries - Russia and Belarus. After all, most of the owners of Polish companies note that they did not check their contractors because of the lists of EU-sanctioned enterprises, which can have a negative impact on them.
Companies that work closely enough in the Russian and Belarusian markets, have branches there or regularly deliver cargo there, are at the greatest risk.
Therefore, we recommend that all Polish entrepreneurs carefully check who you are dealing with.
