Advance Release Order requires original production and binds supplied material to authorisation conditions, limiting supply by quantity and value. The ARO/Invalidation letter is a DGFT form directing an indigenous producer/STE to supply listed goods against an Advance Authorisation/DFIA; the original must be produced, it is valid for a stated period, supplied goods remain subject to the underlying authorisation conditions, quantity and value are limiting factors, and supply and receipt must be confirmed by signed statements from the producer and the holder.
