Welcome to the Web Site of the Hallmarking Convention!
The Convention on the Control and Marking of Articles of Precious Metals (also known under “Hallmarking Convention” or “Vienna Convention”) is an international treaty between Contracting States, which aims at facilitating the cross-border trade of precious metal articles. The scope of the Convention is strictly limited to the control of the precious metal content – not to health, security or other aspects of precious metals articles.
States, which are party to the Convention, recognise that articles, which have been marked with the Convention “Common Control Mark” (CCM) and which are of a legal fineness, can enter their territory without additional control or marking. The number of CCM-marked articles has grown over the years – a sign that there is a demand for quality precious metals articles (see yearly statistics).
