Indian Standard “IS 15820:2009 General Requirements for Establishment and Operation of Assaying and Hallmarking Centres” is the basis for recognition of Assaying and Hallmarking Centres. A centre desirous of obtaining recognition, after setting up of the Centre shall apply on the prescribed application form to BIS along with their Quality Manual, developed on the basis of Generic Quality Manual. A Pre-recognition Initial Assessment of the centre will be carried out by a team of two auditors of BIS for two days to check implementation of the documented system, availability of facilities for sampling, testing, assaying and Hallmarking as per the relevant Indian Standards, competency of available manpower including their training, availability of adequate safety and security arrangements and commitment to follow BIS guidelines issued from time to time. The list of equipment required, is available in the Generic Quality Manual. Based on satisfactory assessment, recognition is granted to the centre for a period of 3 years. The centre shall be required to submit an Agreement on Rs 100/- non-judicial stamp paper signed jointly with BIS prior to grant of recognition.The centre shall also be required to submit an affidavit-cum-undertaking duly notarized on Rs.100/- non-judicial stamp paper and an indemnity bond on Rs 20/- non-judicial stamp paper duly notarized.


The recognition of a centre after 3 years is renewed based on satisfactory performance observed during surveillance assessments conducted periodically without advance intimation and renewal assessment. A recognized centre can Hallmark articles of only BIS licensed jewellers. The Hallmarking of articles can be done only after ensuring conformance of purity of precious metal (gold/silver) in the article received from a particular jeweller with respect to the declared fineness as per provisions of relevant IS. Samples are also collected periodically by BIS from stock of Hallmarked articles on sale by licensed jewellers. These samples are tested at BIS laboratory or a referral laboratory notified by BIS thereby counterchecking the purity of precious metal in the article sold with Hallmark.
