Free Safety & Security Declarations Checklist for UK Importers

A Free Compliance Guide for UK Importers

Safety & Security (S&S) declarations changed significantly in 2025. Use this checklist to stay compliant and avoid costly customs delays — ensure your S&S submissions are accurate and timely.

What are Safety & Security Declarations?

Safety & Security (S&S) declarations are advance notifications required by HMRC before goods arrive in the UK. These electronic submissions provide border authorities with early warning about incoming cargo for security screening purposes.

Key Updates in 2025:

Expanded data requirements for high-risk commodities
Enhanced penalties for late or incorrect submissions
New submission deadlines for different transport modes
Additional validation checks by customs systems

Why This Matters:

Non-compliant S&S can hold up your goods for days
Penalties range from £100-£2,500 per violation
Repeated failures may trigger enhanced scrutiny
Affects all import methods (sea, air, road, rail)
