Under the Regulation 2019/452, Member States may maintain their existing investments screening mechanisms (21 Member States currently do), adopt new ones or remain without such national mechanisms. The Commission keeps an up-to-date list of screening laws in the EU. Member States must notify the Commission who may issue an opinion when an investment threatens the security or public order of more than one Member State, or when an investment could undermine a strategic project or programme of interest to the whole EU, such as Horizon 2020 or Galileo. The final decision remains with the Member State.

Art. 85 of the Utilities Directive (2014/25/EU) contains provisions allowing contracting public entities to reject foreign goods not covered by any EU international commitments from its tender procedures. In these cases, a tender submitted for the award of a supply contract may be rejected where the proportion of the products originating in third countries exceeds 50% of the total value of the products constituting the tender (Art. 85.2). Additionally, in cases of equivalent offers, the provisions provide for a preference for European tenders and tenders covered by EU's international obligations. In practice, this possibility has rarely been used.
In Poland, the Directive has been transposed with the the publication of the consolidated text of the Act - Public Procurement Law.

Certain public records have to be stored in archives in specific locations in the Netherlands. This applies both to paper and electronic records. The government organisations regularly make a “selection list” which categorises the type of information that should be kept and for how long.

After 20 years, the government organisations transfer such documents to the National Archives or to a local or regional archive service located in The Netherlands.
