Customs Declarations UK Launches NCTS6 Solution for Efficient Transit Declarations
On Tuesday, August 25, 2026, Customs Declarations UK announced the full launch of its New Computerised Transit System (NCTS6) solution, which enables customs agents, freight forwarders, hauliers, and traders to file T1 and T2 transit declarations, generate the Transit Accompanying Document (TAD), and manage departures and arrivals from a single platform. This solution is now live on the HMRC CTC Traders API, making the process of filing transit declarations easier and more streamlined.
The launch of NCTS6 follows the United Kingdom’s migration to NCTS Phase 6 on June 1, 2026, which introduced updated data, security, and API requirements aligning transit procedures with the EU’s Import Control System 2 (ICS2). To support this change, AJ Software Solutions Ltd (trading as Customs Declarations UK) has been listed by HM Revenue & Customs on the official GOV.UK register of NCTS software developers. This list is the government’s published register of software providers offering New Computerised Transit System solutions to the trade.
The New Computerised Transit System is the platform that controls the movement of goods under Union and Common Transit, allowing customs duty and taxes to be suspended while goods travel under customs control between offices of departure, transit, and destination across the EU and the wider Common Transit Convention (CTC) area. For businesses moving goods between Great Britain and the EU, or operating the Ireland-to-Europe landbridge via the UK, transit declarations are a daily operational requirement, and the transition to NCTS6 has raised the technical bar for every departure and arrival.
The Customs Declarations UK NCTS6 solution addresses this requirement end-to-end. Users can file T1, T2, and T2F transit declarations at the office of departure, receive the Movement Reference Number (MRN), and generate the Transit Accompanying Document (TAD) once the movement is released. They can then manage arrival notifications and unloading remarks at the office of destination from the same account. The platform also enables declarants to use their own comprehensive guarantee (GRN), guarantee waiver, or individual guarantee, retaining full control of their financial cover.
This solution applies real-time validation of commodity codes, EORI numbers, and Guarantee Reference Numbers before submission, significantly reducing rejections and border holds. Efficiency features include guided step-by-step wizards, a streamlined Compact Mode for high-volume users, bulk CSV and Excel upload, cloning of existing movements for repeat trade lanes, the ability to build a transit declaration directly from an existing CDS export declaration, and AI-assisted document processing (Customs Intelligent Document Processing – IDP), which extracts data from invoices, packing lists, and CMRs to populate declaration fields.
Director of Customs Declarations UK, Jawahir Lal Lund, said, “Transit is the connective tissue of GB–EU trade, and the move to NCTS Phase 6 was the most significant change to the regime in years. Our goal was simple: make NCTS6 a routine workflow rather than a technical burden. Businesses can now file a T1 or T2, generate the TAD, and manage the arrival at destination in minutes — using their own guarantee, on a platform that validates every declaration before it reaches HMRC. We aim to make CDUK a one-stop customs platform for customs agents, freight forwarders, hauliers, and traders, so that they can handle transit, CDS import and export declarations, safety and security filings, and GVMS/ELO movements through one account instead of juggling multiple systems.”
The NCTS6 solution is available now on flexible pay-as-you-go terms with no monthly fee or minimum commitment. Custom subscription plans with volume discounts are available for regular and high-volume filers. To learn more, visit www.customs-declarations.uk.
