Gold hallmarking is mandatory only for gold jewellery and artefacts in India. Since April 1, 2023, the six-digit Hallmark Unique Identification (HUID) number has become compulsory for jewellers before selling the item. However, now the hallmarking is expected to become mandatory for all types of gold, including imported gold, bullion, and gold purchased by jewellers, tentatively from January 2025, as per a report by Hindustan. According to it, the Bureau of Indian Standards (BIS) and concerned stakeholders have agreed to make hallmarking mandatory for all types of gold and the BIS committee has submitted the report on the matter.
