The Bureau of Indian Standards (BIS) has ordered the immediate closure of a hallmarking centre in Chennai and initiated action to de-recognise it permanently.

Following a “surprise visit” to the facility, BIS authorities found and sealed about 42 kg of gold jewellery.

As part of a market surveillance exercise a couple of months ago, BIS had collected some jewellery from a licensed jeweller hallmarked by the A-1 Hallmarking Centre and assayed it at the BIS referral lab only to find it to be under caratage. It asked the centre to stop hallmarking activities with immediate effect. Butthe agency continued the “unethical practice,” according to an official statement.

Following this, BIS officials visited the hallmarking centre and found 42 kg of gold jewellery. Of this, 12.6 kg was said to be spuriously hallmarked.
