Please see Notice to Exporters 2022/04 informing about introduction of new trade sanctions on Russia introduced on 1 March 2022. The measures in Russia (Sanctions) (EU Exit) (Amendment) (No. 3) Regulations 2022 include a list of critical-industry goods and critical-industry technology which are prohibited for export, supply or transfer to, or for use in Russia, along with the provision of technical assistance, financial services and brokering services.
Guidance on the scope of sanctions against Russia, including the circumstances in which licences can be granted, can be found on the GOV.UK Russia sanctions: guidance page.
There are also financial sanctions against Russia and further information is available from the Office for Financial Sanctions Implementation (OFSI).
You are advised to open the Notice to Exporters and all embedded hyper-links to see the full scope of the sanctions.
You should also read Notice to Exporters 2022/03 with action taken, suspending use of extant export licences for dual-use items to Russia and licences with Russia as a final destination. NTE 2022/03 also includes the list of open general licences for which ECJU has removed Russia as a permitted destination.
As a business, it is your responsibility to read the new legislation and take appropriate action.
