Submit CBAM Reports

Once your CBAM report is generated in kolum, the final step is to submit it to the EU Commission via the CBAM Transitional Registry. This ensures your compliance with the CBAM Regulation and completes your quarterly reporting.

Below is a clear, step-by-step guide to help you submit your CBAM report seamlessly.

1. Log in to the CBAM Transitional Registry

Go to the CBAM Transitional Registry and log in with your credentials.

After logging in, navigate to My Quarterly Reports. You will see a table listing each quarter with the current report status.

2. Upload the .zip File

Identify the quarter for which you wish to submit your report and click the Upload button on the right side of the row. This will open a modal allowing you to upload your CBAM report file.

3. Select and Upload the File

Click Choose File in the modal, then select the .zip file you exported from kolum. Confirm your selection by clicking OK.

You should see a green success message confirming the file upload.

4. Validate the Uploaded Report

Click on the blue report ID link (e.g., 39INUH3D...) next to the “Draft” status to open the report details page.

Here, click the Validate button at the top right of the page. The system will check your uploaded report for format and content consistency.

You will receive a green confirmation once validation succeeds.

5. Submit the CBAM Report

Once validation is complete, simply click the Submit button at the top right of the report page to finalize your submission to the EU Commission.

Your CBAM reporting obligation for the quarter is now fulfilled, and you will see your report status updated in the registry.

Tips for a Smooth Submission

• Ensure the exported .zip file from kolum is the final, correct version for the quarter you are submitting.

• If validation fails, review the feedback in the registry, correct any issues in kolum if needed, and re-upload.

• Keep a record of your submission confirmation for your compliance documentation.
