How to access and use the New Computerised Transit System (NCTS) to submit electronic transit declarations when moving goods.

Check when to use the NCTS

The New Computerised Transit System (NCTS) is an online system for submitting transit declarations and notifications to HMRC.

If you’re a UK trader, you must use NCTS if you want to move goods under the Common Transit Convention (https://www.gov.uk/guidance/check-if-you-can-use-transit-to-move-goods-to-the-eu-and-common-transit-countries).

The Common Transit procedure can be used for movements between the UK, the EU and other common transit countries.

You can keep up to date with news affecting NCTS users by reading the transit newsletters (https://www.gov.uk/government/publications/community-common-transit-and-tir-newsletters).

If you use the Transports Internationaux Routiers (TIR) procedure

The TIR procedure is used for transit operations that begin, end, or move through a third (non-EU) country that has signed the TIR convention.

You must declare these goods to the NCTS for any part of the journey within Northern Ireland or the EU.

When not to use the NCTS

You cannot use the system:
- for certain goods moving by air, sea, or rail — find out more in the Transit Manual Supplement (https://www.gov.uk/government/publications/transit-manual-supplement)
- for certain movements of goods between approved temporary storage facilities (https://www.gov.uk/guidance/how-to-put-goods-into-a-temporary-storage-facility)
- to submit proof of Union status declarations (T2L) documents
What you need before you move goods

To move goods and use the NCTS, you need:
- an EORI number or common transit country trader identification number
- your business address
- a guarantee
- the Customs Declaration Service entry number (for free circulation goods)
- details of the vehicle transporting the goods
- a description of the goods
You can use transit simplified procedures (https://www.gov.uk/guidance/apply-for-transit-simplifications-consignor-or-consignee-status) when moving goods under transit.

Using a Transit Accompanying Document (TAD) to move goods

Goods moving under the transit procedure may be accompanied by a TAD for presentation at their destination. This is useful if:
- the goods are diverted
- there are any incidents during transit
This document includes your consignment’s Master Reference Number printed in numeric form and as a barcode. You must print barcodes to the ISO code 128 standard, rather than European Article Number (EAN) 128.

When consigning multiple items, you must include a list of the items with the TAD.

You can print the TAD and list of items at your premises. You’ll need a printer that can print in the legally required format, including the barcode. If your printer is not configured correctly, you can print these at the office of departure. The system authenticates it, so customs do not need to stamp it.

It’s important that the goods and TAD are presented to customs at the office of destination, to inform the NCTS that the goods have arrived.

You can present the TAD Master Reference Number with a barcode digitally, as an alternative to paper.

What you need to use the NCTS

To use the online service, you need:
- a Government Gateway user ID (https://www.gov.uk/log-in-register-hmrc-online-services) — if you do not have a user ID, you can create one the first time you register
- access to a computer that can download and print Adobe Acrobat PDF documents
- a good quality printer for printing barcodes — to print your TAD and (if applicable) your list of items
To access the NCTS

You can use either:
- third party software — this may be useful if you’re running a larger business and it’s possible to integrate it with other import or export software
- the free-to-use NCTS web channel (https://www.gov.uk/new-computerised-transit-system) — suitable for traders who are low volume users
Using software

You can develop your own software for delivering messages direct from your organisation, or use a service provider that will do this on your behalf.

If purchasing software, you should read the list of known software providers (https://www.gov.uk/government/publications/ncts-software-developers). If you want to develop your own software, contact the Software Developers Support Team by emailing: xxx@xxx.xx (mailto:xxx@xxx.xx).

Your software must be fully compatible with the NCTS and connect using the Common Transit Convention trader application programming interface (API).

You should check with your suppliers before buying software. When developing your software, you must successfully complete specific test scenarios before use.

Using the NCTS web channel

To use the web channel, you must set up an account to use the NCTS to send transit declarations (https://www.gov.uk/guidance/submit-union-transit-declarations-through-ncts).

If the NCTS service is unavailable

You can check if the service is available (https://www.gov.uk/guidance/new-computerised-transit-system-service-availability) or if there is any planned downtime.

If the service is unavailable you can use the Business Continuity Procedure (BCP) to start a transit movement.

Find more information about the BCP and how to complete and submit an offline TAD in the Transit Manual Supplement (https://www.gov.uk/guidance/transit-manual-supplement/6-the-business-continuity-procedure).

After you submit your declaration

By submitting a transit declaration into the NCTS, you’re indicating that you intend to move declared goods through a specified route to a final destination.

If there are any errors, the system will tell you what you need to correct before your declaration can be accepted.

If your declaration is accepted

The customs office of departure will be notified.

The customs office will check and validate your request before your goods are released.

The system will send you a Master Reference Number.

Your goods will be allowed to travel by Border Force.

When your goods are released, the system will tell any other customs offices involved in the journey that the goods are on their way.
