When contacting Assay Offices via email, please provide one of these details: taxpayer number or the number of the activity title.
There is a need to create a range of different official marks for precious metals (gold, silver, platinum and palladium) to indicate their respective legal fineness, in view of the need to ensure consumer protection, promote fair competition between economic operators in the sector and tackle issues like falsification, which have existed almost since the dawn of time.
The assay office mark guarantees the precious metal type and fineness of precious metal articles.
