Who has to check whether a label is permissible?

The duty to check sits with the company displaying the label. Anyone using a third-party label that does not meet the legal requirements is liable themselves. An assurance from the label owner is not enough; what counts is whether the underlying scheme actually meets the criteria and whether its conditions are publicly available.

Three questions make this checkable: is the certification system publicly documented? Does an independent body accredited for the task carry out the assessment? Can the individual certificate be looked up? At flustix the certification programmes are in the download centre, testing is done by laboratories accredited to ISO/IEC 17025, and every licence number can be viewed in the database.
