Brexit: The Time Has Come

UK border controls and customs procedures take effect on January 1, 2021. Temporary measures will allow for a transition in three stages during the first half of 2021 before full UK border controls are implemented on July 1, 2021. If you have been living in denial, the time has come to take Brexit seriously and understand its impact on customs and trade. 


After January 1, 2021, the movement of goods, people, and capital between the UK and the EU will be subject to customs formalities just like any other third country. Customs declarations will need to be filed, new authorisations will be required, customs procedures will need to be followed, and operations will undergo checks and controls. Formalities will take place over a six-month time period, with full controls entering into force on July 1, 2021.

Even if the EU and UK conclude a Free Trade Agreement, customs formalities and checks will apply to the movements of goods between the two parties.

Minimise Delays with Zero-Touch Customs Compliance

Lengthy delays are projected at the UK border, as it is anticipated that many economic operators will not be ready to complete the required customs formalities by January 1, 2021. C4T’s Customs Accounting System (CAS) automatically generates UK customs declarations to be sent to the customs authorities with the click of a button. As declarations are automatically generated, trucks are released faster at the borders, drastically reducing waiting times and minimising delays. Manual interactions are only needed in case of exceptions, allowing your customs team to focus on growing the business instead of fire-fighting to resolve errors. Our customs compliance solution  manages all legal requirements for you, so you are always up-to-date, without the hassle of continuously following the news.

CAS is already compatible with CHIEF and has single message/double filing functionality. With one single message, CAS simultaneously addresses export customs formalities from the country of departure (UK or EU) and import formalities in the country of destination (UK or EU), combined with transit to ensure frictionless border crossing. 


Visual Flow - single message double filing_v4


CAS is integrated with UK, Belgian, Dutch, French, Swiss, and Irish customs authorities as well with customs brokers globally. These integrations make CAS the only customs platform you need, taking care of your customs formalities by either filing them directly to the respective customs authority or by providing the information to a customs broker who will finalise the filing process. You will get an overview of all customs formalities lodged, independent of import/export country, all incorporated into the dashboards and analytics available through our Insights module.

Save Costs

CAS will help you to save costs by:

  1. automating your UK customs declarations.
  2. standardising processes for greater efficiency.
  3. optimising customs processes, such as Special Procedures, for significant savings on customs duty.
