BIS steps up market surveillance to protect consumers

Shri S. D. Dayanand, Head of the BIS Chennai Branch Office, said that BIS regularly undertakes market surveillance and enforcement activities to ensure that products covered under mandatory BIS certification and hallmarking requirements comply with the prescribed standards.

He said such enforcement actions are important to prevent the sale of substandard products, check misuse of the BIS Standard Mark and Hallmark, and maintain consumer confidence in the certification and hallmarking system.

BIS states that hallmarking provides an official indication of the purity or fineness of precious metal articles. Under the current hallmarking system, hallmarked gold jewellery carries the BIS logo, purity/fineness and a six-digit Hallmark Unique Identification (HUID) number. Consumers can also use the BIS CARE app to verify the HUID of hallmarked jewellery.

Legal action initiated

Appropriate legal action is being initiated against the concerned persons under the Bureau of Indian Standards Act, 2016.
