Import of wireless equipment requires WPC import licences or ETA; self declaration routes exist for OEMs and TSPs via Saral Sanchar. Import of wireless transmitters/receivers/transceivers requires WPC import licence; devices in license exempt bands need ETA which may be obtained by self declaration for specified finished products (supported by a Saral Sanchar import undertaking) or by scrutiny based ETA for DGFT 'Restricted' items which then require an RLO import licence. OEMs with valid DPLs may import transceivers/radio modules without separate WPC import licences subject to undertakings and reporting; TSPs may import on self declaration via Saral Sanchar. Experimental, trial, manufacturing, testing and demonstration licences include import permissions but prohibit commercial sale and require compliance with technical, stocking and reporting conditions.
