LEGAL MARKS OF OTHER MEMBER STATES
Articles of precious metal from a member state of the European Union (EU) or the European Economic Area (EEA) may be placed on the domestic market without the need for assay and marking by the assay office, provided that:
- The economic operator’s manufacturing responsibility mark or equivalent is registered with the assay office;
- The assay office mark and standard mark have been previously recognised by the Portuguese Quality Institute (IPQ, I.P.)
Articles of precious metal from a EU or EEA Member State that are exempt from marking under the terms of the respective legislation, but are not exempt from marking under the scope of Portuguese legislation, must be assayed and marked in advance by a Portuguese assay office or a recognised assay office of the country of origin, so that they can be placed on the domestic market.
