The Commission for Protection of Competition has launched an ex officio investigation of a competition infringement against the company VAILLANT doo from Belgrade, a distributor of heating equipment of the “Vaillant” and “Protherm” brands, due to the reasonable assumption that the said company determines the resale prices of the said brands in the Republic Serbia, and carried out a dawn raid on its premises. The Commission compared the wholesale and retail prices from the price list of Vaillant with the retail prices displayed on the websites of certain authorized distributors and determined that they are identical, both among all of the observed retailers, and to the prices from the price list available on the website of Vaillant. At the same time, based on the available data, the company Vaillant is not present on the retail market of products of the “Vaillant” and “Protherm” brands, but only through its distributors. Based on the analysis and evaluation of the collected data, the Commission reasonably assumed the existence of a competition infringement, in the sense of Article 10 of the Law, in the form of a prohibited restrictive agreement, by which the company Vaillant determines the resale prices of the products of the “Vaillant” and “Protherm” brands, i.e. to its distributors. All persons who possess data, documents or other relevant information which may contribute to establishing the facts of this case are hereby invited to submit them at the address of the Commission for Protection of Competition, Savska 25 / IV, Belgrade.
