Customs

Customs represents the regulatory touchpoint for internationally traded goods.

The role of customs, like any law enforcement agency, is to ensure compliance with the law. The regulatory requirements for which customs has administrative responsibility include import, export, and transit of goods, as well as any matters that are administered on behalf of other agencies, such as health, agriculture, taxation, environment, statistics.
