If the UK leaves the EU without a deal, goods traded between the UK and the EU after 11pm on 29 March 2019 will be subject to the same requirements as third country goods, including the payment of duty and import and export declarations. For UK exports arriving at the EU border, the EU will require payment of customs duty at the rate under the EU’s Common Customs Tariff.
Currently, all Scentblotterstrips shipments to countries outside the EU are shipped using DDU terms with any duties paid by the customer. 

So to avoid possible extra costs/duties, delays and longer delivery times, we are advising our all EU customers to order ASAP.
