Brexit Customs Border
The Brexit Customs Border took effect on January 1, 2021, when the Brexit transition period ended and goods moving between Great Britain and the European Union became subject to customs declarations and checks.
What happened and why it matters
The Brexit border showed that a zero-tariff trade deal does not mean frictionless trade, and it changed how ecommerce brands ship between the UK and the EU. The UK left the EU single market and customs union at 11 p.m. on December 31, 2020, a week after the two sides agreed a Trade and Cooperation Agreement. The deal kept tariffs at zero for goods meeting rules of origin, but every shipment now needed export and import declarations, and VAT applied on entry. Many brands added a separate UK or EU stock location or switched to delivered duty paid shipping to avoid surprise charges for customers.
