Mandatory hallmarking for gold jewellery and gold artefacts came into effect on 16 June 2021. It applies to six categories of gold: 14k, 18k, 20k, 22k, 23k and 24k. The mandatory scheme is being implemented in three phases with 256 districts covered in the first phase.

Our report discusses: 

  • guidelines under mandatory hallmarking
  • the hallmarking unique ID (HUID) system, transitional issues with HUID and its current status1 
  • likely developments following the implementation of mandatory hallmarking in India. 

We believe that mandatory hallmarking will be positive for India’s gold market, improving transparency and giving consumers more confidence in the purity of the gold they buy. With no opportunity for under-carating, retailers may place greater emphasis on design and customer service enhancements. Mandatory hallmarking should boost the reputation of the Indian gold market and has the potential to increase jewellery exports.


1HUID is a six-digit alpha-numeric code tagged on to each piece of jewellery to identify assaying and hallmarking centres (AHCs) or the jeweller who had hallmarked the jewellery. HUID was implemented on 1 July 2021 – at present it is restricted to assaying and hallmarking centres (AHCs) and not individual jewellers.
