Responsibility marks and hallmarks
Anyone who produces and/or sells products made from gold, silver or platinum stamped with a fineness (e.g. 'S925' for silver) must stamp the product with a hallmark.
A sponsor's mark shows who is the producer or importer, and makes it possible to identify who made the product, e.g. a particular goldsmith. Applications for hallmarks must be submitted electronically to the Norwegian Industrial Property Office via Altinn. You must pay an application fee before your application can be processed; see the Norwegian Industrial Property Office's price list.
The stamping of a sponsor's mark in an EU/EEA country can mean that an importer or dealer does not need to apply for a Norwegian hallmark.
