What is internal customs?

 

Internal customs is a public authority responsible for the control and management of goods (as well as services and information) entering or leaving a national territory. Unlike border customs, internal customs intervenes in stages, checking the proper application of regulations even after the physical entry or exit of goods.
Its main functions include:

  • Verification of regulatory compliance of goods and services
  • Application of duties, taxes and fees
  • Monitoring compliance with tax, health and safety regulations
  • Fraud and trafficking prevention
  • Supporting companies in customs practices

Why is internal customs important?

 

Internal customs plays a strategic role in facilitating international trade. Thanks to its controls:

  • Compliance with EU and national rules is ensured
  • Consumers, the environment and businesses are protected
  • You speed up customs processes if the paperwork is correct

 

What are the main documents required?

 

To avoid blockages or delays, it is essential to carefully prepare all the required documents. Here are the main ones:

  • Transportation Document (CMR, B/L, AWB)
  • Detailed commercial invoice
  • Customs Declaration (SAD)
  • Customs codes and tariff headings (HS Code)
  • Certificates of origin or compliance, if required
  • Documents for VAT and import duties
