Using TR421 in procurement

NUTS codes identify the place of performance of a contract. A notice published on TED carries a NUTS code alongside its CPV code: the CPV code says what is being bought, the NUTS code says where it will be delivered. Notices normally use the most specific level available, which for Kocaeli is NUTS 3.
