What is the subject matter of the contract?

The subject matter of the contract is the substantive description of what the public contracting authority wishes to procure, and thus forms the core of every procurement procedure. It determines which procedural rules apply, whether EU thresholds are relevant, and how the specifications must be designed.

Procurement law fundamentally distinguishes three categories of subject matter:

• Works contracts: Building and civil engineering services as well as related engineering services
• Supply contracts: Purchase, leasing, rental or hire-purchase of goods
• Service contracts: All other services not classified as works or supply contracts

Significance of the Classification

The correct classification of the subject matter of the contract is decisive for the choice of the applicable rulebook and the level of the relevant EU threshold. Works contracts are subject to a significantly higher threshold (EUR 5,538,000) than supply and service contracts (EUR 143,000 for central government authorities, EUR 221,000 for other contracting authorities).

For mixed contracts that comprise several categories, the applicable law is determined by the main subject of the contract. The "centre-of-gravity rule" applies: decisive is the financial value or the functional significance of the predominant performance component.

Subject Matter of the Contract and Specifications

The subject matter of the contract is specified in the procurement procedure through the specifications. The specifications must describe the subject matter clearly and completely enough that all bidders understand the tender in the same way and can submit comparable tenders. An unclear or contradictory description of the subject matter may lead to the cancellation of the procedure.

FAQ

What happens if the subject matter of the contract is incorrectly classified? An incorrect classification may lead to the application of the wrong threshold and thus render the entire procedure unlawful under procurement law. Bidders can challenge this in review proceedings.

May the subject matter of the contract be amended during an ongoing procedure? Material amendments to the subject matter of the contract during an ongoing procedure are in principle not permitted. They would require cancellation and a new tender.
