Customs Declarations UK adds NCTS6 transit filings as HMRC lists it as provider

Customs Declarations UK has launched a cloud-based NCTS6 transit declarations tool as the UK’s move to Phase 6 raises the bar for cross-border filings. HMRC has also added the company to the GOV.UK register of NCTS software developers, giving agents, hauliers and traders another option for T1 and T2 transit work.

Why it matters: - Transit declarations are a daily requirement for many businesses moving goods between Great Britain and the EU, including traffic on the Ireland-to-Europe landbridge. - NCTS Phase 6 adds updated data, security and API requirements, so filing errors can mean delays, rejections and border holds. - A single platform that handles departure, transit and arrival steps can reduce manual work for customs agents, freight forwarders, hauliers and traders.

What happened: - Customs Declarations UK launched its NCTS6 solution, extending its cloud customs platform to cover transit declarations. - HM Revenue & Customs listed AJ Software Solutions Ltd, trading as Customs Declarations UK, on the official GOV.UK register of NCTS software developers. - The platform is live on the HMRC CTC Traders API. - The launch follows the UK migration to NCTS Phase 6 on 1 June 2026.

The details: - Users can file T1, T2 and T2F transit declarations at the office of departure. - The platform generates the Movement Reference Number and the Transit Accompanying Document once the movement is released. - Users can manage arrival notifications and unloading remarks at the office of destination from the same account. - Declarants can use a comprehensive guarantee, guarantee waiver or individual guarantee. - The system applies real-time validation of commodity codes, EORI numbers and Guarantee Reference Numbers before submission. - The product includes guided step-by-step wizards and a Compact Mode for high-volume users. - Bulk CSV and Excel uploads are supported. - Users can clone existing movements for repeat trade lanes. - The platform can build a transit declaration from an existing CDS export declaration. - Customs Intelligent Document Processing extracts data from invoices, packing lists and CMRs to populate declaration fields. - The NCTS6 solution is available on pay-as-you-go terms with no monthly fee or minimum commitment. - Matching arrival is included at no extra cost when the departure is filed on the platform. - Custom subscription plans with volume discounts are available for regular and high-volume filers. - The broader Customs Declarations UK platform also supports GB CDS import and export declarations, GB Safety and Security Declarations, GVMS, EU ICS2 Entry Summary Declarations and the French ELO. - The platform has direct integrations to HMRC and Community System Providers including MCP, CNS and CCS-UK. - Customs Declarations UK says it is trusted by hundreds of businesses and powers thousands of monthly declarations.

Between the lines: - The HMRC register listing can make the platform easier for trade users to find as NCTS6 adoption grows. - The feature set is aimed at reducing friction in a process that has become more technical under Phase 6. - The pricing model appears designed to lower the entry barrier for smaller filers while still serving high-volume operators.

What's next: - Customs Declarations UK is positioning the NCTS6 tool as part of a wider one-account customs workflow. - The company plans to keep linking transit filings with CDS import and export, safety and security, and GVMS/ELO movements. - Businesses that need transit capability will continue adjusting to the new Phase 6 data and API rules as they work through live filings.

The bottom line: - Customs Declarations UK is betting that simpler transit filing, real-time validation and HMRC listing will help it win more cross-border trade users.
