Plan your international shipment with confidence

  Are you planning an international shipment and want to make sure everything goes smoothly with customs? One of the most critical steps is understanding how internal customs works. Knowing the rules, what documents to prepare, and how the procedures unfold is essential to avoid delays or penalties. In this article, we guide you step by step through everything you need to know about internal customs: its roles, required documentation, and key procedures.

What is internal customs?

  Internal customs is a public authority responsible for the control and management of goods (and in some cases, services and data) that enter or exit a national territory. Unlike border customs, internal customs operates in later phases, verifying compliance with applicable regulations even after goods have physically crossed the border. Its main functions include:

• Verifying compliance of goods and services with national and international regulations
• Applying duties, taxes, and customs charges
• Enforcing fiscal, health, and safety standards
• Preventing fraud and illegal trade
• Supporting businesses with customs-related processes

Why Internal Customs Matters

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

• Compliance with EU and national regulations is ensured
• Consumers, the environment, and companies are protected
• Customs processes can be expedited when documents are properly prepared

 

What Documents Are Required?

  To avoid delays or complications, it is crucial to prepare the correct documentation. The key documents include:

• Transport Document (CMR, Bill of Lading, AWB)
• Detailed Commercial Invoice
• Customs Declaration Form (SAD/DAU)
• HS Codes and Tariff Classification
• Certificates of Origin or Compliance, when required
• Tax Documents for VAT and import duties

Internal Customs Isn’t Just for Physical Goods
