Sales of USB Type External Hard Drives (HDDs) sold in India must comply with Indian Standard IS 13252 (Part 1), so the BIS CRS (Compulsory Registration Scheme) certification is required for them guaranteeing safety and quality. Manufacturers have to send test reports, have their products tested at a BIS-registered lab, and finish an application with the necessary paperwork. Authorized Indian Representatives (AIR) are required of foreign manufacturers. Certified goods earn the BIS Standard Mark for lawful sale in India following BIS assessment. This system guarantees Indian market consumer safety and product dependability.
