The British Hallmarking Council (BHC), established by Parliament to oversee hallmarking in the UK, has revealed plans to introduce a new Dealer’s Notice next year.

The Dealer’s Notice, which must be displayed by all dealers supplying precious metal jewellery, is being updated to add two new marks, in a version that will be compulsory from 1 May 2020.

The updated version incorporates:


  • A new differentiated hallmark for articles hallmarked outside of the UK by Birmingham Assay Office
  • A new type 2 standardised CCM mark.

One of the requirements of the Hallmarking Act 1973 is that all dealers supplying precious metal jewellery (or other items made of precious metal) shall display a notice explaining the approved hallmarks. This must be the notice produced by the BHC.

From 1 May 2020 the revised version will be the only legally recognised notice.

The New version

The Dealer’s Notice has been updated to incorporate:

  • A new differentiated hallmark for articles hallmarked outside of the UK by Birmingham Assay Office: the new differentiated Birmingham hallmark is now the only assay office mark being used on articles marked in Birmingham Assay Office’s sub-office in Mumbai. The new mark consists of a vertical anchor and a compass with a cut cornered rectangular outline.  The decision to invoke a differentiated mark to be used by UK offices hallmarking outside of the UK was made by the British Hallmarking Council in March 2018.  The use of this mark has been compulsory since 1 April 2019.
  • A new type 2 standardised CCM mark: The type 1 or traditional CCM conformity mark uses a different shield shape for each precious metal. It also always contains the millesimal fineness of the alloy.  The new type 2 or standardised CCM mark is a single generic conformity mark used for all precious metals and finenesses.  It must be accompanied by a mark specifying the millesimal fineness of the alloy and a unique mark for each precious metal or the chemical symbol for the precious metal.  These accompanying fineness and metal identifying marks can be separate or combined.

Following a 6 month period of grace this will become the only acceptable version as of May next year.  This therefore replaces the previous version, last amended in 2015.

The new version 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.

The BHC have also created a suitable format for online retailers to use.

Although the Hallmarking Act makes no express reference to the internet, the BHC’s view is that it applies to sales of, and other dealings with, articles made of precious metal conducted over the internet and accordingly dealers supplying precious metal articles online should display the Dealer’s Notice on their websites.
