Export-control measures are designed for two purposes: (1) to keep a
check on outgoing strategic or short-supply materials, and (2) they
are instituted also for foreign-exchange reasons. For price-checking
purposes in order that foreign-exchange losses can be prevented,
exporters must register with agencies designated by the Ministry of
Finance. Customs authorities do not permit exportation without a
certificate of registration and destination. All foreign currency
receipts are turned over to the Central Bank of Turkey.
