In the competitive world of public procurement, understanding the legal framework is not just an advantage – it’s a necessity. For any company aiming to supply goods, deliver works, or provide services to the Croatian public sector, the Public Procurement Act (Zakon o javnoj nabavi – ZJN) is the cornerstone regulation that governs every step of the process. Misinterpreting its principles can lead to disqualification, while mastering them can open significant opportunities.
1. What is the Croatian Public Procurement Act (ZJN)?
The Croatian Public Procurement Act is the primary law regulating how public authorities (contracting entities) purchase goods, services, or commission works from private companies (economic operators). Its main purpose is to ensure that public funds are spent efficiently, transparently, and fairly, fostering open competition and preventing corruption.
The Act aligns Croatian procurement practices with EU directives, ensuring a standardized and fair process across the single market.
The ZJN is more than a legal requirement – it’s the rulebook that shapes how businesses can access Croatia’s multibillion-euro public procurement market.
2. Why Understanding ZJN is Crucial for Your Business
Compliance with ZJN is not just about legal obligation – it’s about positioning your business for success. Key benefits include:
- Increased competitiveness: Know the rules, craft compliant and strategically strong bids.
- Reduced risk: Avoid common pitfalls like procedural errors or incomplete documentation.
- Fair opportunity: All bidders are treated equally, giving you a level playing field.
- Efficiency: Understanding processes saves time and resources, letting you focus on winning bids.
- Transparency and accountability: Gain clarity on how decisions are made and hold contracting authorities accountable.
3. How It Works: Key Elements of the ZJN
Fundamental Principles
The Act is built on principles derived from EU law:
- Free movement of goods and services – no barriers to business across the EU.
- Equal treatment and non-discrimination – all suppliers must be treated equally.
- Transparency – all procedures and decisions must be open to review.
- Proportionality – requirements must match the subject of the contract.
Procurement Thresholds
ZJN applies only when contract values reach certain thresholds:
- Goods and services: €26,540 or more
- Works: €66,360 or more
- Special thresholds apply for diplomatic and consular procurements.
Procurement Procedures
The Act defines several procedures contracting authorities may use:
- Open procedure – all interested suppliers can submit a bid.
- Restricted procedure – only pre-qualified candidates are invited.
- Competitive procedure with negotiation – allows negotiation to tailor bids.
- Competitive dialogue – for complex projects requiring in-depth discussion.
- Innovation partnership – aimed at developing and later purchasing innovative solutions.
Award Criteria: Economically Most Advantageous Tender (EMAT)
Gone are the days of contracts going to the lowest price. Under ZJN, contracts are awarded based on the Economically Most Advantageous Tender (EMAT). This means contracting authorities consider not only cost but also other value-adding factors, such as:
- Quality
- Lifecycle cost
- Environmental or social aspects
A higher-quality, sustainable, or innovative bid can often win over a cheaper but less valuable alternative.
4. Limitations and Challenges
While ZJN creates a fair and transparent system, businesses may face challenges:
- Extensive documentation requirements
- Strict submission deadlines
- Appeal procedures that may cause delays
Understanding these challenges is the first step toward overcoming them and preparing winning bids.
5. Conclusion: Turn Knowledge into Opportunity
The Croatian Public Procurement Act is not just a set of rules – it’s your gateway to a lucrative market. By mastering its principles, procedures, and requirements, you can transform legal complexity into a competitive advantage.
Prepare thoroughly, submit compliant and compelling bids, and position your business to win public contracts.
