BIS registration requirement enforced for notified electronics imports; random sampling and compliance testing determine customs clearance. Imports of goods notified under the Electronics and Information Technology Goods (Requirement of Compulsory Registration) Order, 2012 require BIS registration or a MeitY exemption; Customs must verify registration, use the Risk Management System to select consignments for random sampling, and send samples to BIS recognized labs to test defined non destructive safety parameters. Out of Charge clearance is granted only if samples comply; failing consignments may be re exported or destroyed at the importer's cost. MeitY authorises Customs to deform and dispose of non compliant or unregistered notified goods.
