Become a supplier

Politecnico di Milano establishes and prepares the list of economic operators in order to identify the parties to be consulted for the awarding of contracts by direct awarding and negotiated procedure with no call for tenders, pursuant to Article 50 of Italian Legislative Decree No 36/2023.

The list of economic operators is set up electronically by means of the “SINTEL” Electronic List of Suppliers, the Online E-Procurement System of the Region of Lombardy - and its Electronic List of Suppliers.

For access to and participation in the Politecnico di Milano’s list of economic operators, the tools and information systems provided for SINTEL access are used and are available at the following address:

Home - ARIA (

Politecnico di Milano therefore invites interested economic operators to apply for registration in Politecnico di Milano’s List of Suppliers for goods and services through the SINTEL system.

Those eligible for registration in the List of Economic Operators are economic operators who are not in situations that exclude them from participation in tender procedures under Art. 94 of Legislative Decree No. 36/2023.

The List is used by the different facilities of the University to choose suppliers from whom to request quotations; the aim is both to conclude a direct award and to invite to negotiated procedures for the supply of below-threshold works, goods and services and in accordance with the principles of transparency, of rotation, of equal treatment, of non-discrimination, of impartiality and of proportionality in addition to the effectiveness, the efficiency and the cost-effectiveness of the administrative action.

The List is always open throughout its duration for the registration of economic operators that possess the requirements laid down by the Regulations.

Registration to Politecnico di Milano’s Electronic List of Suppliers is effective for the entire duration of the list, subject to maintaining the requirements laid down for the registration and the renewal of the related declarations and documentation submitted for registration.

Where Politecnico di Milano intends to make use of the List for the purposes of Art. 50 of the Public Procurement Code, the registered economic operators will be consulted without further forms of advertising.

Recourse to the List for the award of supply procurement will always take place and, in any case, in compliance with applicable legislation on the obligation to make use of the PA Electronic Market by CONSIP and the conventions/framework agreements entered into by CONSIP spa.

Registration on the List does not involve the award of any contract, it does not imply rights or expectations of any kind in favour of the economic operator, nor does it establish an entitlement to the award of supplies or services and neither is Politecnico di Milano bound in any way towards the registered economic operators.
