The Brexit transition period ends on 31 December 2020.
There will be significant changes to the way that Import and Export business is conducted and the documentation needed, even if a Free Trade Agreement is ultimately reached with the EU.
Time is running out to consider the impact of the changes on your business and to carry out any necessary preparation, if you haven’t already done it.
A good place to start is by completing the ‘Make sure you’re ready checklist’: https://www.gov.uk/transition
This gives the option to sign up for email updates about changes that may affect you.
Detailed guides are also available:
If you are not already confident in dealing with non-EU Imports and Exports you may want to consider engaging a Freight Forwarder or Customs Agent/Broker to assist: https://www.gov.uk/guidance/appoint-someone-to-deal-with-customs-on-your-behalf
You should review your contracts with your main Import and Export suppliers and customers to ensure that the most suitable International Terms and Conditions of Service (INCOTERMS) are used.
