Subject: CBAM information handoff — [installation] / [reporting period]

Hello [supplier contact],

We are coordinating information for [product family] from [installation reference], for [reporting period]. Please help us confirm the following items through our agreed business channel.

1. Installation: confirm the reference, country and person responsible for this record.

2. Sharing: confirm which record and period were shared, the intended declarant and the date. Confirm EORI directly through the trusted business contact; do not post it publicly.

3. Retrieval: [declarant contact] to confirm whether that exact record is visible. If not, please describe the unresolved step without sharing account credentials.

4. If actual emissions are planned: identify the verification contact and current report status. If a report is not yet available, please state the next step and expected availability. This request does not assume the report is already due.

5. Agree one owner and next action for each unresolved item. Please reply by [business coordination date — not a legal deadline].

Please do not send passwords or personal identification documents with this initial reply. Agree a secure channel before transferring sensitive evidence.

Thank you, [name / organisation]
