General Technology Note (GTN)

The export of 'technology' which is 'required' for the 'development', 'production' or 'use' of items controlled in Categories 0 to 9 is controlled according to the provisions in each Category. 'Technology' 'required' for the 'development', 'production' or 'use' of a controlled item remains controlled even when applicable to a non-controlled item. Controls do not apply to that 'technology' which is the minimum necessary for the installation, operation, maintenance (checking) and repair of those items which are not controlled or whose export has been authorised. Controls on 'technology' transfer do not apply to information 'in the public domain', to 'basic scientific research' or to the minimum information necessary for patent applications.

General Software Note (GSN)

The Lists do not control 'software' which is either: 1. Generally available to the public by being: a. Sold from stock at retail selling points, without restriction, by means of: (1) Over-the-counter transactions; (2) Mail order transactions; (3) Electronic transactions; or (4) Telephone call transactions; and b. Designed for installation by the user without further substantial support by the supplier; or 2. 'In the public domain'.

Category 3 - Electronics

This category covers electronic components (including semiconductors), integrated circuits, electronic assemblies and related equipment. Controls focus on performance thresholds such as operating frequency, power output, timing parameters for integrated circuits, and radiation hardening specifications. It also covers high-performance ADCs/DACs, microwave components (MMICs), and field programmable logic devices (FPGAs). The 2025 update introduced new MMIC definitions and added controls for electronic assemblies containing programmable logic devices.

Catch-All Clause - Article 4 of Regulation (EU) 2021/821

Article 4(2): If an exporter is aware that dual-use items which he proposes to export, not listed in Annex I, are intended, in their entirety or in part, for any of the uses referred to in paragraph 1, he must notify the competent authority. That authority shall decide whether or not the export concerned is to be made subject to authorisation. Article 4(3) & (4): Member States may adopt or maintain national legislation imposing an authorisation requirement for WMD-related catch-all and military end-use catch-all.

Cyber-Surveillance Catch-All - Article 5 of Regulation (EU) 2021/821

Article 5(1): An authorisation shall be required for the export of cyber-surveillance items not listed in Annex I if the exporter has been informed by the competent authority that the items in question are or may be intended, in their entirety or in part, for use in connection with internal repression and/or the commission of serious violations of human rights and international humanitarian law. Article 5(2): If an exporter is aware, pursuant to its due diligence findings, that cyber-surveillance items which it proposes to export, not listed in Annex I, are intended, in their entirety or in part, for any of the uses referred to in paragraph 1, he must notify the competent authority.
