Correct answer: Jewellery
The BIS Hallmark on jewellery certifies the purity of gold and silver ornaments. The Hallmark logo (triangle/BIS mark with purity grade) is used exclusively on jewellery. As of June 2021, BIS hallmarking became mandatory for gold jewellery in India. It is NOT used for agricultural products, electronics, or electrical goods (which use ISI mark).
