As the deadline for transitioning from the Customs Handling of Import and Export Freight (CHIEF) system to the Customs Declaration Service (CDS) approaches, it is crucial for UK traders to take the necessary steps to ensure a seamless shift in their export declarations.
The last day for making export declarations through CHIEF is fast approaching on 30 March 2024. After this date, all export declarations must be processed via the CDS. Here’s what you need to do to prepare:
Step 1: Subscribe to CDS
To make the transition as smooth as possible, subscribing to the CDS is imperative. You will need the following information to complete the subscription process:
- Governmental Gateway user ID and password
- EORI number that begins with GB
- Unique Taxpayer Reference (UTR)
- Business address registered with HMRC’s customs records
- National Insurance number (for individuals or sole traders)
- Business start date

What to Do After Subscribing
Currently, HMRC is ensuring that the CDS accommodates all export routes and various types of export declarations processed at the border. It is advised not to initiate the migration of export declarations to the CDS unless instructed by HMRC or your software provider.
After subscribing to the CDS, get in touch with your software provider to verify the following:
- If their software is authorized for submitting export declarations through the CDS
- Whether you can access their software to use the free Trader Dress Rehearsal (TDR) service, allowing you to practice submitting export declarations in a secure test environment
Information for Current NESWeb Users
For traders currently utilising the National Export System web service (NESWeb) to process export declarations via CHIEF, it is essential to subscribe to the CDS. Furthermore, an upcoming HMRC service, “Make an Export Declaration Online,” is set to replace NESWeb and is expected to launch this winter. HMRC will notify you when this service becomes available for your use.
Get started now
In summary, with the March 30th deadline for the CHIEF to CDS transition looming, it is imperative for UK traders to act promptly. By subscribing to the CDS and following the necessary steps, traders can ensure their export declarations continue to be processed efficiently and compliantly. For further assistance or clarification, contact HMRC or your software provider. Stay proactive and make this transition a seamless one for your business!
