Silver jewellery hallmarking with digital traceability rolled out

Buying silver jewellery is set to get safer and more transparent. The government has rolled out a new voluntary hallmarking system for silver articles, effective September 1, 2025, complete with a digital traceability mechanism to ensure purity and protect consumers.

Digital HUID System for Silver

The Bureau of Indian Standards (BIS) has revised its hallmarking standard, publishing IS 2112:2025, which replaces the older 2014 version.

Under the new system, every hallmarked silver article will carry a Hallmark Unique Identification (HUID) code, similar to gold. 
This will let buyers trace key details, article type, purity grade, hallmarking date, testing centre, and jeweller’s registration number via the BIS Care mobile app.

Expanded Purity Grades

The updated standard introduces seven purity grades — 800, 835, 925, 958, 970, 990, and 999. Grades 958 and 999 are new additions. Each hallmark will now have three components:

BIS Standard Mark with ‘SILVER’

Purity Grade

HUID Code

Currently, India has about 230 BIS-recognised Assaying and Hallmarking Centres spread across 87 districts. In FY 2024–25 alone, over 3.2 million silver articles were hallmarked.

Stakeholder Backing & Awareness Push

BIS consulted with over 80 stakeholders — jewellers, testing centres, and consumers, earlier in August to finalise the move. The bureau is also running awareness campaigns through its branches and social media to educate buyers.

Consumer-Friendly Move

With digital hallmarking, the government aims to empower buyers, curb malpractices, and boost trust in the silver jewellery market making sure every piece you buy comes with purity you can verify.
