On 23 June 2016 the UK held the United Kingdom European Union membership referendum, where the electorate of the UK and Gibraltar were asked whether they should remain a member of, or leave, the European Union. 51.89% of voters voted to leave, and on 29 March 2017 the UK government implemented the withdrawal process. The UK was originally due to leave the EU on 29 March 2019, which was later extended until 31 October 2019 and then again to 31 January 2020.
At 11pm on 31 January 2020 the UK formally left the European Union. The two sides will negotiate their future trade, travel and other arrangements during a transition period which will last until 31 December 2020. During this transition period the UK is not part of any of the EU's political bodies, but remains subject to EU law, and is still part of the customs union and single market.
No, not directly, and certainly not yet.
Shipping and customs arrangements with all countries outside the EU remain unchanged. This means that:
In the future the UK may negotiate new trade agreements with your country which could affect these import taxes, but at the moment the arrangements are unchanged.
As a UK company all of our products are priced in GBP. Since the referendum the value of GBP has dropped considerably
This is an impossible question to answer and I'm not qualified to speculate. Since the referendum the value of the pound has dipped, which causes some raw materials to increase in price which of course has then resulted in some price increases. As a company which exports a lot the additional administrative overhead may lead to further cost increases, but we can't be sure of any of this until negotiations are completed and we understand what our future relationship with the EU will be.
Currency fluctuations are dependent on the market's judgement of the value of the pound relative to other currencies, so this may fluctuate during negotiations.
