The 1973 Hallmarking Act outlines the legal requirements for assaying, hallmarking and selling of precious metal items in the UK.
There are three main areas with which a retailer selling precious metal items to UK consumers must comply:
1. Ensuring items that are not exempt carry a recognised hallmark.
2. Ensuring precious metal descriptions are accurate.
3. Ensuring that the mandatory Dealers Notice is displayed for consumers.
To fulfil your legal obligation in point 3, Dealers Notice A provides you with a detailed explanation of the Hallmark and should be displayed in a prominent position when retailing pieces.
This notice can also be displayed on online retail sites as part of a standalone page detailing wider
information about product quality. Download a copy of Dealers Notice A for display here.
Dealers Notice A
However, we are aware that Dealers Notice A is not ideal for the online environment, so we have developed Dealers Notice B in two versions, PDF and a short film as an alternative for online sales platforms where a dedicated page on hallmarking is not possible.
