Customs declarations

Definition

A customs declaration is the formal statement submitted to customs authorities that describes goods being imported, exported or moved under a customs procedure. It records the goods’ classification, quantity, value, origin and destination, and it is the basis on which customs authorities assess duties and taxes. Declarations are usually submitted electronically by a customs broker, carrier or the trader.

Why does a customs declaration matter?

The customs declaration is the legal record of what is crossing the border. An accurate declaration allows goods to clear quickly and ensures the correct duties are paid. An incorrect or incomplete declaration can lead to delays, penalties, back-payment of duties and, in serious cases, prosecution. For businesses, declarations also feed into trade statistics and audits, so errors can cause problems long after the goods have arrived.

How do customs declarations work in logistics?

The declarant gathers the commercial invoice, packing list, transport document and any certificates, then completes the declaration in the customs system. Each item is assigned a tariff code, its value and origin are stated, and the correct procedure is selected, such as import, export or transit. The declaration is submitted before or at arrival, and customs may accept it, check it or ask for more information. Once accepted, the declaration allows the goods to be released or moved under transit.

Types of customs declarations and procedures

  • Import declarations for goods entering the country
  • Export declarations for goods leaving the country
  • Transit declarations for goods moving under customs control
  • Temporary admission declarations for goods used and re-exported
  • Declarations for bonded warehouse entry and exit
  • Simplified declarations for low-value or frequent shipments
  • Supplementary declarations after clearance

Example in practice

A furniture importer in Varna, Bulgaria receives a container of wooden tables from a manufacturer in Vietnam through the port of Varna. Before the container arrives, a customs broker in Varna submits the import declaration, listing the tariff codes, the declared value of €48,000, and Vietnam as the country of origin. The declaration is accepted, duties are calculated, and the importer pays them to the customs office. Customs then release the container for free circulation, and it is transported by road from the port to the importer’s warehouse.
