Exchange control copy retention: authorised dealers retain and forward duty free licence originals to central bank; photocopies suffice for discharge. Authorised dealers must retain the Exchange Control copy submitted for letters of credit or remittances and forward the original to the central bank after full utilisation with related R Returns. Licensing authorities should not insist on surrender of the Exchange Control copy and may accept a photocopy with annexures plus an authorised dealer certificate confirming surrender of the original for discharge of export obligation.
