Display the Dealers Notice
Under the Hallmarking Act 1973 all dealers supplying precious metal items must display a notice explaining the approved hallmarks. This must be in the form produced by the British Hallmarking Council.
Display this notice in your premises where customers can see it.
Online retail sites must also prominently display explanatory information about the hallmark. This can be either:
- as Dealers Notice A
- as Dealers Notice B (available as a PDF or a short film as an alternative for online sales platforms where a dedicated page on hallmarking is not required)
How to get the Dealers Notice
For physical display in shops, Dealers Notice A is available as a free download from any of the Assay Office websites, and high quality printed versions are also available. For those requiring large quantities of notices artwork is available for retailers to produce their own signs.
Dealers Notice A is available in the following formats.
High quality gloss, free standing printed versions are available from the Assay Offices for a charge of 15 plus VAT and postage.
