Ankara, 30 June 2025 — The Turkish Competition Board has concluded its investigation into alleged anti-competitive practices in the construction chemicals market, imposing substantial fines on two companies for violating competition law.
The probe focused on possible breaches of Article 4 of the Competition Act No. 4054, which prohibits agreements that restrict competition.
The Board found that:
- Mapei Yapı Kimyasalları İnşaat San. ve Tic. AŞ fixed resale prices and imposed vertical restrictions related to regions and customers.
- Chryso-Kat Katkı Malzemeleri San. ve Tic. AŞ engaged in similar price fixing, vertical restrictions, and additionally imposed non-compete obligations on buyers.
As a result, the Competition Board imposed administrative fines amounting to approximately $1.66 million USD on Mapei and about $605,000 USD on Chryso.
No violations or fines were imposed on other investigated companies, including Akkim Kimya, BASF Türk, Fosroc, and others, nor on the two industry associations involved: the Concrete Admixtures Manufacturers Association (KÜB) and the Building Materials Manufacturers’ Federation (YÜF).
The Board also addressed KÜB’s data collection practices, noting that while these could not be fully exempted under the law, they might qualify for individual exemption if the data collection is managed independently via a digital system involving at least five members.
