1. Meaning

Unfair trading conditions arise where an undertaking with substantial market power or a dominant position uses that power to impose contractual or commercial terms that unfairly disadvantage customers, suppliers, business partners, or sometimes consumers.

Under EU competition law, Article 102(a) TFEU expressly identifies as a possible abuse the direct or indirect imposition of unfair purchase or selling prices or other unfair trading conditions by a dominant undertaking.

The basic concern is that a dominant undertaking may be an unavoidable or exceptionally important trading partner. Because counterparties have limited realistic alternatives, the dominant firm may be able to obtain contractual advantages that it could not obtain under conditions of effective competition.

Unfair trading conditions are generally discussed as a form of exploitative abuse, although particular contractual terms can also have exclusionary effects on competitors. Modern competition-law literature distinguishes these non-price abuses from excessive pricing while recognizing that both fall within the language of Article 102(a).

2. Legal Framework

Article 102 TFEU applies where:

1. an undertaking holds a dominant position;
2. it engages in conduct amounting to an abuse;
3. the relevant jurisdictional requirements, including an effect on trade between Member States, are satisfied.

Dominance itself is not prohibited. What matters is the abuse of that position.

Article 102 gives several examples, including:

• unfair purchase or selling prices or other unfair trading conditions;
• restrictions on production, markets, or technical development;
• discriminatory conditions for equivalent transactions; and
• contractual requirements involving unrelated supplementary obligations. 

The list is not exhaustive.

3. What Can Constitute an Unfair Trading Condition?

An unfair condition does not necessarily involve an excessive monetary price. It can concern the non-price terms of the commercial relationship.

Examples may include excessively restrictive contractual obligations, unnecessary restrictions on how a product or service can be used, unreasonable automatic contractual extensions, obligations to pay for services that have not actually been supplied, disproportionately long contractual commitments, or requirements that unnecessarily restrict a customer's commercial freedom.

EU decisional practice has considered matters such as unlimited contractual commitments, unwanted bundled services, flat charges unrelated to services actually received, and unjustified restrictions on product use.

4. How Unfairness Is Assessed

There is no single mathematical formula for deciding whether a contractual term is unfair.

A useful framework is to examine whether the condition is detrimental to the interests of trading partners or affected third parties and whether it is necessary and proportionate to a legitimate objective. Contemporary analysis of the case law describes these considerations as central to identifying unfair non-price terms.

Accordingly, authorities may examine the commercial purpose of the condition, the dominant undertaking's justification, the burden placed on the counterparty, whether less restrictive alternatives exist, and whether the obligation is proportionate to the service or benefit supplied.

The European Commission's 2026 Article 102 Guidelines concern exclusionary conduct, but they note that principles concerning dominance and objective justification are also relevant to other forms of abusive conduct, including exploitative conduct involving unfair trading conditions.

Important Case Laws

1. BRT v SABAM — Case 127/73

Belgische Radio en Televisie (BRT) v SABAM is one of the foundational authorities concerning unfair contractual conditions imposed by a dominant undertaking.

SABAM was a copyright-management organization. The dispute concerned contractual arrangements under which authors transferred extensive rights to SABAM.

The Court considered whether a dominant copyright-management organization could impose obligations on its members that went beyond what was necessary for achieving the organization's legitimate objectives.

The case established an important principle: contractual restrictions imposed by a dominant undertaking may constitute abuse where they unnecessarily restrict the freedom of the other contracting party.

This means that competition law can scrutinize not merely the price charged by a dominant firm but also the substantive contractual obligations imposed on weaker trading partners.

BRT/SABAM remains a leading authority cited in discussions of unfair trading conditions under Article 102.

2. United Brands Company v Commission — Case 27/76

United Brands v Commission is one of the most important Article 102 judgments.

United Brands occupied a powerful position in the banana market. The Commission challenged several aspects of its commercial conduct.

Among other matters, United Brands imposed conditions restricting distributors from reselling bananas while they were still green.

The Court examined whether these restrictions were objectively justified or represented an unreasonable interference with distributors' commercial independence.

The broader significance of the judgment is that a dominant supplier cannot automatically use contractual terms to control the commercial conduct of its customers merely because its market position enables it to do so.

The case is also famous for its discussion of excessive prices, but it remains relevant to unfair trading conditions because it illustrates how restrictions attached to supply relationships may be scrutinized under Article 102.

It also demonstrates the importance of the dominant undertaking being effectively difficult for trading partners to avoid.

3. Alsatel v Novasam — Case 247/86

Alsatel v Novasam concerned contractual arrangements for telephone equipment.

The arrangements included contractual mechanisms involving the duration and continuation of the relationship between the supplier and customer.

The case is significant because it demonstrated that seemingly ordinary contractual provisions can become competition-law concerns when imposed in circumstances involving substantial market power.

A condition such as automatic continuation, modification, or extension of contractual obligations may need examination where it effectively locks customers into the relationship without sufficient commercial justification.

The central lesson is that the legal form of a contractual clause is not decisive. Competition authorities and courts can examine its commercial substance, duration and practical burden on customers.

Alsatel is regularly identified among the European cases relevant to unfair trading conditions.

4. Tetra Pak II — Case C-333/94 P

Tetra Pak International SA v Commission, commonly called Tetra Pak II, concerned Tetra Pak's conduct in markets involving packaging systems for liquid foods.

The litigation covered several alleged abusive practices, including contractual restrictions imposed on customers.

The contractual arrangements restricted aspects of customers' freedom regarding equipment, cartons, maintenance and related activities.

The significance of the case lies in showing how a dominant undertaking can create an abusive commercial structure through multiple interconnected contractual obligations rather than through one obviously unlawful clause.

Competition law can therefore examine the agreement as a whole.

Where customers become commercially dependent upon a system controlled by a dominant undertaking, restrictions concerning equipment use, maintenance, supplies or associated products can reinforce that dependence.

Tetra Pak II consequently remains an important authority concerning non-price abuses and unfair contractual conditions.

5. Duales System Deutschland

Duales System Deutschland (DSD) concerned Germany's packaging-recovery system and the use of the well-known Green Dot system.

The dispute involved charges connected with the use of DSD's system and trademark.

A central competition concern arose where businesses could be required to make payments connected with packaging even where the relevant recovery service was not actually provided by DSD.

This illustrates an important form of potential unfairness:

a dominant undertaking should not use its market position to require payment or contractual consideration that is inadequately connected to the service actually supplied.

The case therefore demonstrates that the fairness assessment can involve examining the relationship between:

obligation imposed → service supplied → commercial justification.

A substantial mismatch between these elements can support a finding of abuse.

Duales System Deutschland is recognized among the important authorities concerning unfair trading conditions.

6. Amministrazione Autonoma dei Monopoli di Stato (AAMS) — Case T-139/98

The AAMS litigation concerned the Italian tobacco sector and contractual conditions connected with distribution.

The case is important because it demonstrates how a dominant undertaking's contractual powers can interfere with the commercial independence of distributors or other trading partners.

The analysis of such arrangements focuses on whether contractual restrictions are genuinely necessary for legitimate commercial purposes or whether the undertaking's market power enables it to impose restrictions going beyond what is reasonably required.

A dominant undertaking may protect legitimate commercial interests. Article 102 does not require it to abandon ordinary contractual safeguards.

However, dominance makes necessity and proportionality particularly important.

AAMS is therefore another recognized authority in the development of EU law concerning unfair trading conditions.

7. GEMA Decisions

The European Commission's GEMA proceedings concerned a German copyright collecting society.

Collecting societies perform legitimate and important functions, but their market position can give them substantial bargaining power over authors, composers and other rights holders.

The cases examined contractual rules governing the relationship between the collecting society and rights holders.

Their broader significance is that even where an organization's basic activity is legitimate, it cannot necessarily impose every contractual restriction that would benefit its administration.

There must be an appropriate relationship between the organization's legitimate objectives and the restrictions imposed upon its members.

The GEMA decisions therefore contributed to the principle that commercial necessity must be distinguished from exploitation of market power.

8. 1998 Football World Cup — Case IV/36.888

The European Commission's 1998 Football World Cup decision provides another illustration of exploitative conduct.

The case concerned arrangements relating to ticket sales for the tournament.

The Commission examined whether conditions imposed on consumers in connection with ticket purchasing unfairly restricted access to tickets.

Its significance extends beyond sport.

A dominant or monopoly-like undertaking controlling access to something consumers cannot readily obtain elsewhere may not simply impose arbitrary conditions because customers lack alternatives.

The case demonstrates how unfair trading conditions can directly affect final consumers, rather than only distributors or business customers.

It is commonly included among significant Commission decisions concerning unfair trading conditions.

Modern Digital-Market Application

Unfair trading conditions have become increasingly important in digital markets because major platforms can determine the contractual conditions under which businesses reach users.

A recent example is the European Commission's Apple App Store/music-streaming decision. The Commission explained that unfair trading conditions can constitute an Article 102(a) abuse where the conditions harm the interests of trading partners or third parties, including consumers, through parameters such as price, choice, quality or innovation.

Another contemporary example is the Commission's proceedings concerning Meta, where the Commission addressed arguments concerning the legal test for unfair trading conditions and stated that Article 102(a) applies to dominant undertakings rather than only legal or de facto monopolies.

These developments show why the doctrine remains important for digital platforms, marketplaces, app ecosystems and other environments where one undertaking controls important access conditions.

Practical Legal Test

A competition authority examining alleged unfair trading conditions can broadly work through the following questions:

Dominance → Condition imposed → Detriment → Legitimate objective → Necessity → Proportionality → Abuse

First, the authority determines the relevant market and whether the undertaking is dominant.

Second, it identifies the precise contractual or commercial condition being challenged.

Third, it considers how that condition affects customers, suppliers, consumers or other affected parties.

Fourth, it examines the undertaking's explanation for imposing the condition.

Finally, it considers whether the condition is genuinely necessary and proportionate to that legitimate objective.

A condition is not abusive merely because a customer dislikes it or because it is commercially demanding. Competition law is particularly concerned with conditions that become possible because of dominance and impose unjustified burdens on parties whose practical bargaining alternatives are limited.

Conclusion

Unfair trading conditions are an important form of abuse of dominance under Article 102(a) TFEU. They allow competition law to address exploitation through contractual terms rather than concentrating exclusively on prices.

The principal authorities—including BRT/SABAM, United Brands, Alsatel, Tetra Pak II, Duales System Deutschland, AAMS, GEMA and the 1998 Football World Cup decision—show that dominant undertakings may retain considerable contractual freedom, but that freedom is not unlimited.

The central issue is whether market power has enabled the undertaking to impose a condition that materially disadvantages trading partners or affected consumers without sufficient necessity or proportionality. The doctrine is particularly relevant where counterparties have little practical bargaining power and where the dominant undertaking controls access to an important product, service, infrastructure, collecting system or digital platform.
