A notified body that subcontracts specific assessment tasks or uses a subsidiary must ensure the subcontractor or subsidiary meets the Article 21 requirements and inform the notifying authority; it keeps full responsibility for their work wherever they are established, may subcontract only with the client's agreement, and must keep available to the notifying authority the documents on the subcontractor's qualifications and the work done.
