INA (website) is the Croatian national petroleum company, once monopolistic and still mainly state-owned; a large part of it was bought lately by the Hungarian national oil company MOL. INA is an economic giant with business in a variety of areas more or less connected with oil. It also include a numbe of daughter companies, some of which have flags of their own. Usually such companies fly their own flag together with the flag of INA and, not unfrequently, with the flag of the "mining industry", green over black with golden miner's hammers, sometimes also with a derrick overall). INA also owns a number of petrol stations all around the country and some in the neighboring countries from former Yugoslavia. While these have previously often used the company flag as presented here, today most of them use vertical knatterfahnen of various merchant campaigns, often quite colorful. The company flag is thus relatively less frequently seen, at the various company headquarters, as a rule.

The flag is blue, vertical, with the company emblem set within a white circle in the upper part of the flag. The emblem consists of the bold, white initials "INA"; there is a blue dot in the upper part of the first letter. This emblem was adopted sometime in the 1970s; it seems to have been regularly used in the subsequent years without the ring and in a number of other variants (photo, photo, photo, photo).

CROSCO (website) is a daughter company of INA. The company does oil drilling and similar research and oil exploitation around the world.
The flag is red with the company logo in the middle, a yellow oval with the company name and a circular emblem in red-white-blue. The flag is hoisted at the company headquarters in Zagreb and, probably, on their oil rigs, too. In Zagreb the flag is hoisted together with two other flags - the mother company flag INA in the middle and at the viewer's left the flag of the "mining industry".
