Fuji made a huge range of store/private brands, usually based on the Superia line. Once these were the next newest emulsion behind current Fuji branded film, but this ended around a decade ago when sales began to slip and Fuji curtailed extensive R&D on consumer emulsions. Colour cast could be poor storage since I'm still shooting always 'fridged Superia that's up to 5-6 years old with no issues.

Check the neg edge code: should be "S-200" if it's recent Superia. If not, then who knows?
