Article 8a IPI Measures 1. Where the Commission finds, following an investigation and consultations pursuant to Article 6, that a third country measure or practice exists, it may, if it considers it to be in the interest of the Union, impose an IPI measure by means of an implementing act. An IPI measure shall only apply if the main object of the procurement procedure falls within the scope of the implementing act, as specified in accordance with paragraph 6 point (a). The design of the procurement procedure shall not be made with the intention of excluding it from the scope of this Regulation. 2. The IPI measure shall be determined on the basis of the following criteria, in light of available information and the Union’s interest: (a) proportionality of the IPI measure with regard to the third country measure or practice; (b) availability of alternative sources of supply for the goods and services concerned, in order to avoid or minimise a significant negative impact on contracting authorities or contracting entities; (c) the engagement of undertakings from the targeted third country in procurement activities in the internal market, benefiting from the lack of reciprocity. 3. The IPI measure shall only apply to procurement procedures with an estimated value of at least EUR 10 000 000 net of value-added tax for works and concessions, and of at least EUR 5 000 000 net of value-added tax for goods and services. 4. The IPI measure shall also apply in the case of specific contracts awarded under a dynamic purchasing system, when those dynamic purchasing systems were subject to the IPI measure, with the exception of specific contracts the estimated value of which is below the respective values set out in Article 8 of Directive 2014/23/EU, Article 4 of Directive 2014/24/EU and Article 15 of Directive 2014/25/EU. The IPI measure shall not apply to procedures for the award of contracts based on a framework agreement. The IPI measure shall also not apply to individual lots to be awarded according to Article 5 (10) of Directive 2014/24/EU or Article 16 (10) of Directive 2014/25/EU. 5. In its implementing act, the Commission may decide, within the scope defined in paragraph 6 of this Article, to restrict the access of operators, goods or services from third countries to procurement procedures by requiring contracting authorities or contracting entities to exclude tenders submitted by economic operators originating in those third countries. 6. The implementing act, adopted in accordance with Article 14(2), shall specify the scope of application of the IPI measure, including: (a) the sectors or the categories of goods, services and concessions based on the Common Procurement Vocabulary set out in Regulation (EC) No 2195/2002 as well as any applicable exceptions therein; (b) specific categories of contracting authorities or contracting entities; (c) specific categories of economic operators. 7. The Commission shall impose an IPI measure, according to paragraph 5, only when the third country measure or practice is sufficiently severe and the potential negative impact due to the limited availability of alternative sources, as provided for in paragraph 2 point (b), is comparatively small. 8. The Commission may withdraw the IPI measure or suspend its application if the third country takes satisfactory corrective actions or undertakes commitments to end the measure or practice in question. If the Commission considers that the corrective actions or commitments undertaken have been rescinded, suspended or improperly implemented, it shall make publicly available its findings and may reinstate the application of the IPI measure at any time. The Commission may withdraw, suspend or reinstate an IPI measure in accordance with the examination procedure referred to in Article 14(2) and followed by the publication of a notice in the Official Journal of the European Union. 9. An IPI measure shall expire five years from its entry into force or its extension, unless a review shows a need for continued application of an IPI measure. Such a review shall be initiated, by a publication of a notice in the Official Journal of the European Union, on the initiative of the Commission nine months before the date of the expiry, and shall be concluded within six months. Following the review, the Commission may extend the duration of an IPI measure for a period of another five years in accordance with the examination procedure referred to in Article 14(2).
