Introduction

TDR allows customers to use a snapshot of the live HMRC CDS system to submit real world examples to in a test environment. Due to the learning curve between we insist that TDR is performed before going live also to relieve Ontech from any claims that, for example:

• Users haven’t had sufficient training / testing time

• Users haven’t had the opportunity to ask how the system works / how to handle declaration rejections

• Users weren’t aware of how CDS may handle declarations differently to CFSP and result in customs duty not / being charged or declarations being submitted with the correct information

Starting TDR

When we link your live system to HMRC’s TDR environment we’ll perform some initial tests to ensure your data flows through as it should. If (through this small initial test) we notice any problems in your data requiring resolution we’ll let you know. As soon your system is linked we’ll email HMRC’s tdrcommunications@hmrc.gov.uk to inform them of the your main contact for them to provide assistance to.

We recommend starting by reading Using CDS day-to-day to learn & familiarise yourselves with the new system, most customers find this enough however if a training session is required it can be requested.

Vision Bond will come pre-configured for our typical customer profile, be aware of these by checking out Configuring CDS. During initial testing these settings won’t matter too much, however it’s compulsory that you check they’re correct and suitable for your organisation especially before going live.

Our Guidance

During TDR we recommend customers to test all scenarios they intend to use in the live system, for example:

• Using the warehouse deferment

• Using customer deferments

• Declarations resulting in zero & positive customs duty value charges payable

• Declarations with quotas

• Declarations with preferences

• Declarations with all commodity types (not necessarily all commodity codes but at least one of each similar group of commodity codes) - i.e. Wines & Spirits, Beers, high strength beers, beers with small producer relief etc

It’s inevitable that some declarations will be rejected and this will give you a good opportunity to get used to fixing them.

Customers migrating from CFSP to CDS

Once sufficient tests have been performed get in contact with our support team to provide a comparison of customs duty payment values returned from CFSP vs CDS. This will highlight any differences for you to look into why they’ve occurred to ensure that when going live you’re submitting everything correctly.
