We always ensure that such transfer takes place only if it is permitted and carried out in accordance with applicable laws. We also ensure that the service provider in question guarantees by agreement or otherwise that privacy is maintained at the same level of protection as the EU. That includes safeguarding such data transfer with necessary organisational and technical security measures. For international transfers, we rely on Standard Contractual Clauses (SCC) introduced by the European Commission. In addition to that, we rely on adequacy decisions passed by the EU Commission provided that the conditions for adequacy (if any) are fulfilled.

Where we disclose personal data to other companies within the Trelleborg group, we enter into an Intra-Group Data Transfer Agreement, implementing the European Commission Standard Contractual Clauses to any such transfer.
