The public market in Türkiye is a massive and reliable trade arena for companies of all sizes. For international firms and contractors looking to secure government contracts, understanding the local regulatory framework is the key to success. This guide examines the fundamental rules of doing business with public institutions, municipalities, State-Owned Enterprises (SOEs), and social security organizations under the framework of Public Procurement Law No. 4734 (Kamu İhale Kanunu).
1. Identifying the “Contracting Authorities” (The Scope)
Article 2 of the Public Procurement Law clearly defines which organizations are bound by these rules. Before submitting a bid, it is vital to know if the entity you are dealing with falls under this scope:
-
General and Special Budgetary Administrations: This includes central government bodies like Ministries (Bakanlıklar) and Universities (Üniversiteler).
-
Municipalities and Special Provincial Administrations: Local governments (Belediyeler) and their affiliated revolving fund organizations.
-
SOEs (State-Owned Enterprises): Known locally as KİT (Kamu İktisadi Teşebbüsleri), these are commercial entities owned by the state, such as energy or transportation authorities.
-
Social Security Institutions: Funds like SGK (Sosyal Güvenlik Kurumu / Social Security Institution) and other legal entities performing public duties.
2. The Rules of the Game: Fundamental Principles
Public procurement in Türkiye is governed by strict legal principles. Article 5 of the Law mandates that Contracting Authorities ensure: Transparency, Competition, Equal Treatment, and Reliability. These principles are the legal guarantee for international firms that their rights will be protected. For example, unless there is a natural functional link, the procurement of goods (mal alımı), services (hizmet alımı), and construction works (yapım işleri) cannot be combined into a single tender. This prevents anti-competitive bundling.
3. Prequalification: What is Required to Participate?
To become a “Tenderer” (İstekli / A company submitting a bid), you must meet the qualification criteria specified in Article 10. Authorities may request:
-
Economic and Financial Standing: Documents such as Bank Reference Letters (Banka referans mektupları) or your company’s balance sheets.
-
Professional and Technical Qualification: This includes Work Experience Certificates (İş deneyim belgeleri), personnel status, and technical equipment capacity. For foreign firms, your previous international projects can often be used to satisfy these requirements, provided they are properly notarized and apostilled.
4. Tender Procedures: Which One Will You Enter?
In Türkiye, tenders are primarily conducted through three different procedures:
-
Open Procedure (Açık İhale Usulü): The most transparent method where any eligible tenderer can submit a bid.
-
Restricted Procedure (Belli İstekliler Arası İhale): Used for projects requiring specialized expertise. Only those invited after a pre-qualification evaluation can bid.
-
Negotiated Procedure (Pazarlık Usulü): A specific method used for urgent situations (like disasters) or technically complex projects, allowing the authority to negotiate technical details and price with the tenderers.
5. Preparing Your Bid: Critical Compliance
When submitting a proposal, you must strictly follow the formal requirements in Article 30. Failure to do so often leads to disqualification:
-
The Tender Envelope: The Tender Letter (Teklif mektubu) and the Bid Bond (Geçici teminat / A temporary guarantee, usually 3% of the bid price) must be placed in an envelope.
-
Sealing: The envelope must be sealed, and the seal must be signed and stamped by the firm. The İKN (İhale Kayıt Numarası / Tender Registration Number) and company info must be clearly written on the exterior.
-
Deadline: Proposals submitted after the exact tender hour are strictly rejected.
6. The Digital Gateway: EKAP
Today, the vast majority of public procurement in Türkiye is handled through EKAP (Elektronik Kamu Alımları Platformu / Electronic Public Procurement Platform). For any international firm, registering on EKAP is mandatory to view tender notices, download documents, and submit electronic bids (e-teklif).
Why International Contractors Search for This?
Foreign firms often use the following search terms when researching the Turkish market. By understanding these concepts, you align your strategy with the most common market entries:
-

Conclusion
Doing business with Turkish government agencies, municipalities, and SOEs requires following a disciplined process defined by Law No. 4734. Mastering the legislation and preparing your documentation with precision will give your firm a significant competitive advantage in this high-volume market.
