Customs declaration

A customs declaration is a form that lists the details of goods that are being imported or exported when a citizen or visitor enters a customs territory (country's borders). Most countries require travellers to complete a customs declaration form when bringing notified goods (alcoholic drinks, tobacco products, animals, fresh food, plant material, seeds, soils, meats, and animal products) across international borders. Posting items via international mail also requires the sending party to complete a customs declaration form.
The declaration form helps the customs to control goods entering the country, which can affect the country's economy, security or environment. A levy duty may be applied.
Travellers have to declare everything they acquired abroad and possibly pay customs duty tax on goods. Some countries offer a duty-free allowance of certain products which may not need to be declared explicitly.
Some nations require a customs declaration form from each person crossing the border, while other nations require one form per family traveling together. A family is usually defined as family members residing in the same household, who are related by marriage, adoption, blood, or domestic relationship.

Post Brexit, the Northern Ireland Protocol came into effect on 1 January 2021, which was subsequently revised under The Windsor Framework, a legal agreement between the European Union and the United Kingdom which adjusts the operation of the Northern Ireland Protocol.
The Customs Declaration Service is also used for declarations on goods movements to or from Northern Ireland, including goods moving from Great Britain to Northern Ireland, but other customs declarations will continue to use CHIEF pending a longer-term move to the CDS. HMRC explains that "CHIEF is a reliable and robust platform" but "its age means it can’t easily keep pace with new technology".
