In order to use the system-to-system communication for ICS2, economic operators must register in the “EU Trader Portal, CBAM Portal” service, as described step-by-step above.
For each system-to-system communication, the default PartyID is used with the economic operator’s EORI number.
In the context of the Self-Conformance Test (ICS2), economic operators can perform a conformance test in the test environment before implementing the system-to-system communication in the production environment.
For this purpose, the required certificates must be registered in the local environment for the conformance test. An additional service called “EU Trader Portal - Conformance” is available in the Customs Portal for this.
