The Bureau of Indian Standards (BIS), Chennai region, has increased drawing of market samples to check the conformity to mandatory hallmarking of gold ornaments and Hallmark Unique ID (HUID) in jewellery.
Hallmarking of gold jewellery and artefacts for 14, 18 and 22 carat jewellery was made mandatory since mid-June 2021 in 24 districts of the State and Puducherry during the first phase.
