The International Procurement Instrument (IPI) introduces measures limiting the access to open EU public procurement tenders of non-EU companies from countries that do not offer similar access to EU companies. The measures apply to tenders worth at least 15 million Euros for works and concessions and 5 million Euros for goods and services, such as the purchasing of computers.
Pursuant to Art. 5, the IPI enables the Commission to investigate third-country measures or practices, adopted or maintained by public authorities or individual contracting authorities, which result in a serious and recurrent impairment of access of Union economic operators, goods or services to the public procurement or concession markets of that third country. When the Commission finds that a third-country measure or practice exists, it may adopt an IPI measure that requires contracting authorities or contracting entities to: impose a score adjustment on tenders submitted by economic operators originating in that third country; or exclude tenders submitted by economic operators originating in that third country.
The Regulation is yet to be implemented by EU Member States. Typically, the implementation by Member States takes 18–24 months on average after adoption.

In January 2022, the European Commission imposed a minimum import price and anti-dumping duties on flat-rolled products of grain-oriented silicon magnetic steel, which is an important material in the production of energy-efficient transformers and large high-performance generators. The measures apply to imports from China, Japan, the Republic of Korea, the Russian Federation, and the United States of America. This is a continuation of measures first introduced in May 2015 by Implementing Regulation (EU) 2015/1953. The minimum import prices (MIPs) currently in force range between 1,536 EUR/tonne up to 2,043 EUR/tonne. They apply to the individually named exporting producers for which individual dumping margins were established from all the countries concerned. If the CIF Union border price is equal to or above the MIP, no duty is payable. Only if import prices are below this level are anti-dumping duties imposed, set at the difference between the import price and the minimum import price, up to a maximum ranging from 21.5% to 39% of the import price. The system of minimum import prices and anti-dumping duties was introduced in 2015, while the level of duties was adjusted in 2022.

In July 1990, the European Commission imposed a definitive anti-dumping duty on imports of silicon metal (HS Code: 280469) from China, which is used also for producing silicon compounds as well as silicon wafers used as electronic semiconductors. This measure was last extended in August 2022. The rate of duty is 16.8% of the net free-at-Union-frontier price, with the exception of the company Datong Jinneng Industrial Silicon Co. whose exports are subject to a duty of 16.3% of the net free-at-Union-frontier price.

In November 2021, The European Commission imposed a definitive anti-dumping duty under the Implementing Regulation (EU) 2021/2011 on imports of optical fiber cables (CN code ex: 8544 70 00) from China. The original duty of 44%, was amended in January 2022 by the Implementing Regulation (EU) 2022/72, establishing a duty on imports of 33.7%, applicable until November 2026.

In January 2022, the European Commission imposed a countervailing duty under the Implementing Regulation (EU) 2022/72 for imports of optical fibre cables (CN code ex: 8544 70 00) from China. The rate of duty on imports from China is 10.3%, applicable until January 2027.

This process is for all devices that work in any band of the Radio Spectrum and it is analyzed if they are in accordance with the technical conditions stipulated in the National Frequency Allocation Table (CNAF or Cuadro Nacional de Atribución de Frecuencias). The natural or legal person who so requires, since it is not an obligation, may request a review of such devices, attaching the technical documentation necessary for the analysis.
