A Major Milestone in Purity Assurance and Curbing Fake
Hallmarking
प्रव तथ: 04 DEC 2025 4:29PM by PIB Delhi
Within the first three months following implementation of mandatory HUID for silver, over 17 lakh pieces
have been hallmarked, reflecting strong uptake among jewellers and consumers. While the Silver
Hallmarking Scheme remains voluntary, HUID marking has been made mandatory for any silver
article that is hallmarked.
Strong Uptake: Over 17 Lakh Articles Already Hallmarked with HUID
Since, the launch of the silver HUID portal, over 17 lakh silver jewellery items have already been
hallmarked i.e. within 3 months. Purity grades 925 and 800 constitute nearly 90% of all hallmarked items.
A significant acceleration has been observed following the introduction of HUID. In FY 2024–25, around
32 lakh silver articles were hallmarked. This surge reflects the strong confidence of consumers and
jewellers in the HUID system.
Trends in silver hallmarking shows Southern Region of the country leading in volume of hallmarking
followed by Western and Eastern region. Among product categories, payal / anklets constitute the largest
share and are predominantly hallmarked in 800 purity grades. Silver diyas follows, generally in 800 and
925 purity.
Shri Pralhad Joshi, Union Minister for Consumer Affairs, Food and Public distribution tweeted and
highlighted that - "HUID in silver jewellery hallmarking marks a significant step forward in strengthening
purity assurance and eliminating fake hallmarking practices. With HUID mandatory on voluntarily (BIS)
Hallmarked Silver articles, each piece carries a unique 6-digit identification code that enables complete
digital traceability and enhanced consumer protection. With over 17.35 lakh articles already hallmarked
under the HUID system, the initiative is driving greater transparency, accountability and confidence
among consumers and stakeholders. #HallmarkHUID"

The Bureau of Indian Standards (BIS) has announced the introduction of Mandatory Hallmarking Unique
Identification (HUID) for silver jewellery and artefacts with effect from 1 September 2025, marking amajor step towards strengthening consumer protection, purity assurance, and preventing fake
hallmarking.
What is HUID?
HUID is a six-digit alphanumeric code laser-marked on each hallmarked silver article, in addition to the
BIS Standard Mark, the word SILVER, and the purity grade. This unique identifier provides complete
digital traceability of every hallmarked silver item, bringing silver hallmarking on par with the existing
HUID-based hallmarking system for gold.
Verification Made Simple Through BIS CARE App
Consumers can instantly verify the authenticity of hallmarked silver jewellery by entering the HUID on
the BIS CARE mobile app (available on Android and iOS). The app displays key details such as:
Purity of the article
Type of jewellery (ring, anklet, chain, etc.)
Details of the jeweller who submitted the article for hallmarking
Details of the Assaying & Hallmarking Centre
This ensures transparency and empowers consumers to make informed purchases.
It is a user-friendly mobile app for Android and iOS, enhancing consumer access and engagement beyond
its web portal. The app supports 12 languages (10 regional, Hindi, and English) and is free to download.
Coverage of Purity Grades
Silver jewellery hallmarking was first introduced on a voluntary basis in October 2005, and the revised
Indian Standard now includes seven purity grades—800, 835, 925, 958, 970, 990 and 999, with 958 and
999 added recently.

BIS Continues Nationwide Awareness Campaigns
To ensure widespread awareness and smooth implementation of HUID-based hallmarking, BIS is
undertaking:
Consumer outreach and awareness programmes
Interactions with jewellers across all Branch Offices
Targeted social media campaignsThese efforts aim to promote transparency, safeguard consumer interests, and further enhance trust in
hallmarked silver jewellery.
Background
The introduction of HUID in precious metals namely Gold & Silver provides digital traceability helps
curb unfair trade practices ensuring that BIS mark on each jewellery / artefact stands for guaranteed purity
to consumers.
Precious metals such as Gold and silver hold a special significance in India as assets associated with
cultural traditions, social practices and financial security. Ensuring the purity of these precious metals is
therefore essential for protecting consumer interests and promoting trust in the jewellery trade.
Hallmarking plays a crucial role in this regard by certifying the purity and fineness of precious metal
articles, safeguarding consumers from adulteration and supporting transparent fair market practices.
Mandatory hallmarking of gold jewellery and artefacts has been implemented in a phased manner
beginning 23 June 2021, which initially covered 256 districts and over a short span of 5 years, it has been
made mandatory in 373 districts currently, as depicted below: -
This system is supported by 1610 BIS-recognized Assaying & Hallmarking Centres (AHCs) and more
than 2.08 lakh registered gold jewellers. Over 56 crore jewellery pieces have been hallmarked so far, with
7.81 crore pieces hallmarked in 2025-26 alone. The hallmarking workflow i.e. from inward receipt and
weighment to XRF testing, sampling, fire assay and laser marking has been fully digitized, with each
article assigned a unique six-digit HUID.
Building upon the strong foundation created by the HUID system for gold, Bureau of Indian Standards
(BIS) has introduced Mandatory Hallmarking Unique Identification (HUID) for hallmarked silver
jewellery with effect from 1 September 2025, marking a major step towards strengthening consumer
protection and curbing fake hallmarking practices.
