AIS, CCI and National Systems

AIS is a common term for national automated import systems. CCI means Centralised Clearance for Import. These depend on EU legal and data rules but are implemented through Member State systems and timelines.

Key Compliance Points

• Treat system validation as operational evidence, not legal advice.
• Preserve MRNs, authorisation numbers, EORI numbers, document codes and system messages.
• Keep screenshots or exports where permitted for audit trails.
• Link every system record to the legal basis and the transaction.
