A Solution for Supplementary Declarations

The transitional EiDR scheme has been extended to the end of 2021, but this only provides a 175-day window to file supplementary declarations, followed by the final declarations. That means if you used EiDR at the beginning of the year, supplementary declarations imminentare due starting 25 June 2021This requires a simplified declaration procedure authorisation prior the lodging of the first supplementary declaration. C4T can guide you through the process of obtaining this authorisation while onboarding you to CAS, which will provide you with a sustainable—and automated—solution that allows you to take advantage of Special Procedures

Unparalleled Integrations for End-to-End Clearance

CAS integrates with your ERP system or WMS, as well as with customs authorities and port community systems, serving as a customs control tower for all stakeholders. C4T has a close working relationship with HMRC, is connected to CHIEF today, and is in the process of connecting to CDS for a seamless transition as soon as it is launched. We have also integrated with NCTS and GVMS for transit and Community Service Providers such as Destin8 to satisfy formalities at each port. With these integrations, CAS is able to automate your declarations from end to end, with no action needed on your part.  

Go Beyond Compliance

CAS is built modularly, allowing you to start with Declarations functionality for immediate administrative cost savings and scale with value-added modules including Insights,  Special Procedures, Master Data, and Origin Management that provide visibility into the totality of your customs operations and help reduce duty costs. Learn more about how CAS can help you join the next generation of customs.
