What does single market relevance mean?

Single market relevance is a criterion developed by the European Court of Justice that extends the reach of the fundamental freedoms under EU law to public procurement, even where the formal EU procurement directives are not applicable. Below the EU thresholds, Directives 2014/24/EU and 2014/25/EU do not apply directly; however, the primary-law principles of the TFEU – in particular the free movement of goods (Article 34), the freedom to provide services (Article 56) and the general prohibition of discrimination (Article 18) – must be observed if a contract is of single market relevance.

The CJEU has clarified in a series of decisions (beginning with Case C-324/98, Telaustria, 2000) that, even for sub-threshold contracts, contracting authorities must ensure at least an appropriate degree of transparency where the contract is of cross-border interest.

Criteria for establishing single market relevance

Whether a contract is of single market relevance is assessed on the basis of an overall consideration of several objective factors – there is no fixed threshold value.

Relevant criteria according to the European Commission's Interpretative Communication (2006/C 179/02):

• Contract value: The higher the value, the more likely there is interest from other Member States.
• Subject matter of the contract: Certain services (e.g. specialised IT services, research contracts) appeal to companies across the entire EU area.
• Geographical location: Contracts in border regions have heightened single market relevance.
• Technical particularities: Specialised services for which only a few national providers exist.
• Market situation: A lack of suitable national providers increases cross-border relevance.

Legal consequences of single market relevance

If the contracting authority establishes single market relevance, it must observe certain minimum standards even below the EU thresholds.

These include in particular:

• Appropriate publication of the contract (e.g. on national platforms or the authority's own website)
• A sufficient deadline for interested parties from other Member States to submit tenders
• Non-discrimination of bidders from other EU states
• An objective and transparent award decision

A breach of these obligations may render the award decision challengeable and lead to infringement proceedings against the Member State.

Distinction from purely internal situations

Contracts without any cross-border dimension – so-called purely internal situations – are subject exclusively to national law. Distinguishing the two is not always straightforward in practice. Contracting authorities should carefully assess and document single market relevance for every sub-threshold contract in order to minimise review risks.

FAQ

At what contract value is a contract of single market relevance? There is no fixed value. Single market relevance is determined on the basis of an overall consideration (value, subject matter, location, market situation). As a rule of thumb: the closer a contract is to the EU thresholds, the more likely it is to attract cross-border interest.

What happens if single market relevance is wrongly denied? If single market relevance is wrongly denied and the contract is awarded without sufficient transparency, unsuccessful bidders may seek legal protection. The European Commission may also initiate infringement proceedings.

Does single market relevance also apply to de minimis contracts? For very low contract values (e.g. below EUR 5,000), single market relevance is generally not assumed in practice, as the economic interest for foreign companies is typically low in view of transaction costs.
