EPCG nexus fixation revised: regional offices finalize below threshold cases while headquarters handles above threshold applications. Amendments revise EPCG procedural allocation: RLAs grant licences on self declaration and fix nexus for below threshold cases, while headquarters fixes nexus for above threshold applications; committees must finalize nexus within two months based on Chartered Engineer certificates and EPCG nexus norms, failure to do so renders the applied nexus final, and RLAs must maintain sector/industry registers. Appendix 9 now requires a Chartered Engineer certificate detailing end use or essentiality of imported machinery/spares and specific registration or manufacturing licences where applicable.
