While gold hallmarking has been mandatory in India since June 2021, silver hallmarking regulations are also evolving. This guide covers the current status of BIS silver hallmarking and what jewellers and manufacturers should know.
As of 2025, silver hallmarking is voluntary in India — unlike gold hallmarking which is mandatory. However, BIS has been actively developing the silver hallmarking infrastructure and regulations, and mandatory silver hallmarking is expected to follow gold's trajectory.
BIS runs a voluntary silver hallmarking scheme where AHCs (Assaying and Hallmarking Centres) recognized for silver can assay silver purity and apply the BIS hallmark. The silver hallmark includes:
BIS is working on extending the HUID (Hallmark Unique Identification Number) system to silver jewellery — the same 6-character alphanumeric code that now identifies each gold piece. The HUID for silver would enable full traceability of silver jewellery from the AHC through the supply chain to the end consumer.
925 silver (92.5% pure silver, also called Sterling Silver) is the dominant grade for silver jewellery internationally. Indian hallmarking uses the same 925 marking. For export-oriented silver jewellery manufacturers, BIS hallmarking to the 925 purity standard facilitates export to markets that recognize BIS as a credible hallmarking authority.
