In the middle of July, 2017, the food processing facility associated with the Korolivsky Smak brand and operated by Private Enterprise 'Viktor & K' received Halal Certificates for the whole range of its own food products from the two Halal certification authorities: the Halal Global Ukraine Certification Center and the Alraid Halal Certification and Research Center. Based on the newly received certificates, Korolivsky Smak sunflower oil, mayonnaise and mayonnaise sauces, ketchup, tomato sauces, mustard, roasted sunflower seeds and vinegar are all recognized compliant with the Muslim religious tenets, and therefore are Halal and may be safely and freely consumed by all followers of Islam.

In the Korolivsky Smak online product catalog, each Halal product is marked with a special symbol bearing the word HALAL in both English and Arabic characters.
