UK CDS Import/Export Switch

The UK is phasing out CHIEF (Customs Handling of Import and Export Freight) and fully switching to CDS — the Customs Declaration Service. For freight forwarders, this isn’t just a name change — it’s a new filing environment, new data structures, and mandatory digital transition. Are you ready?
👉 In this guide, you’ll learn how to migrate, understand required XML formatting, and future-proof your UK customs process.

What Is CDS for Freight Forwarders?

CDS is HMRC’s new platform for processing import/export declarations.
It supports:

  • 🌐 Real-time data sharing

  • 💼 Digital records of guarantees and authorizations

  • 📊 Multi-line item declarations

  • 📄 Advanced safety & security (ENS) declarations

Unlike CHIEF, CDS requires detailed data mapping — meaning you must align internal systems and processes to new XML schema standards.

How to Switch to CDS freight forwarding

Here’s your operational checklist CDS freight forwarding:

  1. Register for CDS via your Government Gateway

     

  2. Connect your freight system (TMS or ERP) to CDS APIs

     

  3. Set up your Data Declaration Account (DDA)

     

  4. Train your team on new declaration data fields

     

  5. Test XML schema with dummy data using HMRC sandbox

     

  6. Go live before CHIEF sunsets completely

     

🚨 Remember: CDS does not support fallback to paper — all filings are digital.
