In general a certification with eco-INSTITUT-Label is valid for 2 years.

For recertification after that a new laboratory test must be performed.

However, if production procedure or composition of the labelled product changes during validity time of a certification a laboratory test must take place earlier.

After expiration of the first year of its regular validity period a conformity test takes place in which the manufacturers have to verify that production procedure and composition of the respective products have not changed and so continue to comply with the criteria of eco-INSTITUT-Label.

This way only the high claims and quality of eco-INSTITUT-Label can be maintained and garanteed.

Products with expired validity being in recertification process are listed as “pending” in the database.
