UK chemical weapons sanctions

This page provides guidance on the UK’s sanctions regime on chemical weapons, if the UK leaves the EU without a deal.

The UK is leaving the EU. This page tells you about sanctions regimes after Brexit if the UK leaves the EU without a deal, and will be updated if anything changes.

The chemical weapons sanctions regime

The Chemical Weapons (Sanctions) (EU Exit) Regulations 2019 are intended to ensure that the UK can operate an effective sanctions regime in relation to the use and proliferation of chemical weapons after the UK leaves the EU.

This sanctions regime is aimed at deterring the proliferation and use of chemical weapons. This includes encouraging the effective implementation of the Convention on the Prohibition of the Development, Production, Stockpiling and Use of Chemical Weapons and on their Destruction (“the Chemical Weapons Convention”).

When these regulations come into force they will replace, with substantially the same effect, the EU sanctions regime concerning restrictive measures against the proliferation and use of chemical weapons that is currently in force under EU legislation and related UK regulations.
