Foma films are far more prevalent than Kodak (B&W) around the world (except probably North America), they seem to have the distribution right where as Kodak's collapsed in many markets. This is from experience when trying to buy film in various countries, I can always find Ilford, Foma a small amount of Fuji but hardly ever Kodak and Tmax 100 & 400 were the main films I used.
It helps that, like Ilford, Foma make a full range of B&W materials including films, papers and chemistry. There's less incentive for a distributor or a store to sell Kodak particularly outside the major US and European markets. Kodak seem to have concentrated on the Colour/Minilab market.
