From Paul Sparks at the Department for International Trade:
If you’re a UK business trading with Ukraine or Russia and have questions about the current trading situation, contact the UK government's export support team by phone or online: https://www.gov.uk/ask-export-... or contact me directly for guidance.
Also, there are “Sanctions” being placed on trade with Russia. Below is a PowerPoint presentation that is used as part of our free “Export Academy”, this module is on Export Controls, and specifically slide 31 onwards is focussed on “Embargoes & Sanctions”. This presentation (page 31 onwards) explains what sanctions are and gives signposting for you to check up to date information.
