- Why in news
- PIB released a backgrounder on BIS hallmarking on 5 November 2026. It reports that over 65 crore gold articles received HUID numbers as of 15 October 2026.
- What it is
- BIS hallmarking certifies the purity of gold and silver articles against prescribed Indian Standards. The Bureau of Indian Standards runs the scheme, which began as voluntary in 2000. Each hallmarked article carries a BIS mark, a purity mark and a six-digit HUID code.
- Operating agency
- BIS is the sole agency that operates the Hallmarking Scheme in India.
- Gold standard and grades
- IS 1417 covers 7 caratages, from 9K (375) to 24KS (995).
- Testing centres
- Assaying and Hallmarking Centres are recognised by BIS after it verifies their infrastructure, testing facilities and personnel.
Don’t confuse with Gold vs silver hallmarking: Gold hallmarking is mandatory (in notified districts). Silver hallmarking is voluntary, but HUID is mandatory on any silver article that is hallmarked.
Don’t confuse with Fineness mark vs HUID: The purity mark (such as 22K916) states the purity. The HUID is a separate code that identifies the individual article.
Laws, judgments and statutory bodies: 30 Prelims questions since 2013 (what the law says, who chairs, legal basis). In Mains, 44 news-triggered questions, most in GS2, asking for provisions and challenges.
Why it matters
- Gives consumers assurance of purity and cuts adulteration and misrepresentation.
- HUID traceability helps curb duplicate or fraudulent hallmarking.
Problems
- Mandatory coverage is limited to notified districts, so some areas stay outside it.
- Enforcement needs regular surveillance, audits and raids across a large retail base.
Way forward
- Widen district coverage and testing centres, with strict surveillance audits.
- Raise consumer use of the BIS CARE App and HUID verification.

UPSC’s own questions that come close to this issue, from our Prelims and Mains banks.
No practice question for this one; the card may still help an answer. Why: Lasting topic with facts (mandatory gold hallmarking 2021, HUID for silver from September 2025), but BIS hallmarking has no clear news-linked UPSC question record in these counts.
Worth revising until Prelims 2028: most news questions come within two years of the event.
