Food labels currently undergo the quick check only. A detailed assessment will follow.

Missing a label?  

There can be several reasons:

  • It does not belong to one of the listed product groups.
  • The label cannot be found on consumer products.
  • The label has not provided data for assessment on Siegelklarheit.

New labels are added continuously, and additional product groups (e.g., food) are being included
