The Republic of Serbia is preparing to introduce, for the first time, a legal framework to prevent unfair trading practices in supply chains.
The Draft Trade Practices Act for Certain Types of Products (the “Draft Act” and/or the “Act”), approved by the Government of Serbia and now pending before the Serbian National Assembly, would establish certain new rules in relationships between buyers and suppliers. The Act is largely based on EU Directive 2019/633 on unfair trading practices in agricultural and food supply chains, though it goes beyond the EU’s minimum standard in several respects.
Once the Trading Practices Act enters into force, businesses will have four months to comply. The key points for companies preparing for these changes are set out below.
For a more detailed discussion of each of these points, please see the full article below.
Only a few days after the Regulation on the Limitation of Trade Margins[1] ceased to apply on March 1, 2026, major retailers reinstated “off-invoice rebates” to the levels that had applied before September 1, 2025, and in certain cases even increased them. Following this development, the Ministry of Internal and Foreign Trade of the Republic of Serbia (the “Ministry”) announced that three new laws regulating market functioning are to be adopted by the end of March 2026. According to the Ministry, these laws are to replace the Regulation on the Limitation of Trade Margins. One of these laws is the Trade Practices Act for Certain Types of Products, the draft of which was adopted by the Government of the Republic of Serbia on March 5 (the “Draft Act” and/or the “Act”). This will be the first Trade Practices Act adopted in Serbia and represents an important step toward regulating the functioning of the domestic market and creating conditions for more transparent price formation.
The Draft Act is largely modeled on European Union law, particularly Directive (EU) 2019/633 (the “UTP Directive”). The UTP Directive introduces a minimum level of harmonization at the EU level while allowing stricter national laws. This explains why the Serbian Act goes beyond the European regulatory minimum in certain respects. The adoption of a legal framework to prevent and combat unfair trading practices in Serbia may also be viewed in the broader context of Serbia’s EU accession process, particularly in relation to Chapter 11 on agriculture and rural development. In this regard, the adoption of the Act may represent a form of voluntary regulatory alignment with EU legal frameworks even before the formal opening of negotiations in this area.
Unlike the UTP Directive, which applies exclusively to relationships between buyers and suppliers within the agricultural and food supply chain, the Draft Act provides for a broader scope of application. It covers not only agricultural and food products, but also “products of particular importance for market supply”, which include: (i) products of particular importance for consumer supply (such as household cleaning products, paper and kitchen goods, personal hygiene products and cosmetics and diapers), and (ii) products of particular importance for agricultural production (such as plant nutrition products, plant protection products and soil improvers).
Another significant feature of the Draft Act is that it would apply on a mandatory basis, irrespective of the governing law chosen by the contractual parties. In other words, if the buyer and supplier are trading in Serbia, the Act’s provisions shall apply, even if the contract says otherwise.
The Draft Act introduces a requirement that contracts between buyers and suppliers must be concluded in writing (except where a supplier of agricultural products accepts the buyer’s general terms and conditions). Failure to comply with this requirement constitutes a misdemeanor punishable by a monetary fine of RSD 300,000 for a legal entity and RSD 50,000 for the person responsible within the legal entity.
This is a stricter approach than the UTP Directive, which makes it clear that “there should be no obligation to use written contracts”. However, the UTP Directive does recognize that written contracts may help prevent unfair trading practices and that suppliers should have the right to request written confirmation of the agreed supply terms.
The Draft Act also prohibits the use of vague or conditional contractual provisions that leave one party with the discretion to determine the other party’s final financial obligations at a later time. In particular, it prohibits provisions that use indeterminate or relative expressions, clauses referring to future decisions or criteria not incorporated into the contract, or make obligations dependent on subjective or undefined criteria.
The Draft Act sets out what counts as unfair trading practices. The key elements are: (i) the existence of a significant imbalance in bargaining power between the supplier and the buyer; and (ii) unilateral conduct by the buyer that departs from good commercial practice and the principles of good faith and fair dealing, unjustifiably transfers economic risk to the other party, or creates a significant imbalance in the contractual rights and obligations of the parties.
The Draft Act further lists unfair trading practices that are: (i) always prohibited (the “Black List”), and (ii) conditionally permitted only if clearly agreed in advance (the “Grey List”):
(i) The Black List includes:
The prohibition on late payment for perishable agricultural and food products (see above) is one of the key rules set out in the UTP Directive.
In the EU, payment terms in commercial transactions more generally – that is, beyond the agricultural sector – are governed by Directive 2011/7/EU on combating late payment (“Late Payment Directive”). The European Commission’s 2025 Progress Report on Serbia notes that the legal framework for late payments is largely aligned with EU provisions. However, the 30-day payment term reflected in the Draft Act and in the UTP Directive is significant, as it imposes a stricter standard than the general regime under the Late Payment Directive. Whether this tighter framework will improve payment discipline and suppliers’ liquidity in practice, or instead create additional strain for market participants, remains to be seen.
(ii) The Grey List covers practices that are not automatically prohibited if they are clearly and unambiguously agreed in advance in writing, either in a separate agreement or in an annex to the contract. If there is no such agreement, unfair trading practices are deemed to exist where the buyer:
One of the novelties introduced by the Draft Act is the obligation to prepare a specific overview of the financial elements of the contract between the buyer and the supplier. Financial elements of the contract include all monetary aspects of the contractual relationship, in particular, the price of the products, benefits, fees, monetary penalties, and other agreed financial obligations arising from the contract. The Act provides that these elements must be consolidated in a financial overview of the contract (as a single document), which represents a list of all financial obligations arising from the contractual relationship. The overview may be incorporated into the contract, attached as an annex, or prepared as a separate document. The importance of this requirement lies in the fact that any amendment or modification of the contract affecting any financial element must be properly reflected in this overview, which must remain complete and up-to-date at all times. Failure to prepare the financial overview of the contract constitutes a misdemeanor punishable by a fine ranging from RSD 50,000 to RSD 2,000,000 for a legal entity, and from RSD 50,000 to RSD 150,000 for the responsible person.
This solution has two important consequences. First, suppliers gain clearer insight into all costs arising from their business relationship with the buyer. Second, it facilitates enforcement monitoring, as it becomes easier to determine whether certain fees constitute an unfair trading practice. In this respect, the Draft Act goes a step further than the UTP Directive by introducing an additional transparency mechanism.
The Draft Act introduces the prohibition of commercial retaliation, classifying it as a “particularly serious unfair trading practice.” Any form of commercial retaliation or threat of retaliation by the buyer against the supplier is prohibited, particularly if such refers to removal of the supplier’s products from the assortment, reduction of ordered quantities or order frequency, suspension or limitation of services such as marketing services, and other forms of retaliation that may directly affect the supplier’s business operations.
The Commission for Protection of Competition of the Republic of Serbia (the “Commission”) is the authority responsible for enforcement. Its key powers include, among others: (i) deciding on administrative matters, namely determining the rights and obligations of participants in the product supply chain and imposing administrative measures, (ii) adopting by-laws necessary for the implementation of the Act, (iii) carrying out international cooperation in the field of preventing unfair trading practices, (iv) preparing annual reports on unfair trading practices, and (v) maintaining a register of buyers for whom it has been determined that they imposed unfair trading practices.
In the EU, the UTP Directive leaves enforcement to the Member States, with some countries delegating UTP powers to their national competition authorities.
The Commission examines the existence of unfair trading practices ex officio. Although an initiative to open proceedings may be submitted by a broad range of persons (including any natural or legal person, market participants, and any other persons possessing relevant information about a potential unfair trading practice), the submission of such an initiative does not in itself grant the submitter the procedural status of a party to the proceedings. In other words, the Commission independently decides whether to initiate proceedings based on the information, knowledge, or initiatives it receives from various market actors.
The Draft Act also introduces a relatively new mechanism under which a natural person (a cooperating individual in the proceedings, i.e., the whistleblower) who provides decisive evidence unknown to the Commission of an unfair trading practice is entitled to a monetary reward amounting to 5% of the protection measure imposed (see below). The whistleblower, who by definition was or still is involved in the unfair trading practice, enjoys protection of their identity during the proceedings.
Furthermore, the Act provides for both regular and unannounced inspections (dawn raids) to secure evidence. In the course of such inspections, the authorized officer may inspect business premises and vehicles, examine documentation, copy or scan business records, and even temporarily seize documentation or temporarily close business premises for the time necessary to conduct the inspection.
Finally, the Commission is empowered to impose certain measures against the infringing party, including:
By introducing a regulatory framework to prevent unfair trading practices, Serbia will, for the first time, systematically regulate relationships between buyers and suppliers in the supply chains of agricultural and other products important to market supply.
For large domestic and international retail chains active in Serbia, these changes could significantly affect how they structure contracts with local suppliers.
At the same time, greater regulatory alignment with the EU will strengthen the position of Serbian suppliers and agricultural exporters when placing their products on the European market.
All businesses active in the supply chain of products covered by the Act will have to ensure compliance within four months of the Act entering into force. Given the short deadline, companies should already begin conducting an internal review of their existing contractual and commercial arrangements, including revising standard contract templates, general terms and conditions, and internal policies.
