Pursuant to Article 43^{1} of the  Civil Code, a trader is an entity running business or professional activity on their own behalf.


In simple terms: a trader is an entity that runs professional activity for profit-making purposes. Such activity has to be organized and continuous, and not incidental. Thus, a person who occasionally sells things through internet auctions (e.g. to dispose of unused household appliances, clothes or toys) is not considered a trader.


Formal registration of activity does not determine whether one holds the status of a trader, which is extremely important in the context of buyers’ rights. In accordance with the  Civil Code, entities who have not been registered in an appropriate register but nonetheless engage in for-profit activities in an organized and continuous manner are considered traders. Thus, non-registration is not a way to evade regulations protecting  consumers.
