The Laboratory competent for Interoperabilty tests maintains and publishes the list of seal manufacturer codes on its web site (Requirement 401 of Annex 1C).
NB. The requested seal manufacturer code will be inserted as soon we have received a copy of the corresponding certificate.
NB. It's not allowed for a workshop to place a seal from a manufacturer after its revocation date.
NB. As the seal shall be replaced every two years, it's not allowed to find seal from a revocated manufacturer two years after the revocation date.
