Any business producing, processing or selling food, cosmetics, pharmaceuticals or consumer goods in Qatar requires Halal Certification. This means no ingredients or steps in processing are prohibited for observant Muslims.
Because a lot in Qatar follows Islamic laws, both religiously and commercially, obtaining Halal certification is necessary. It guarantees customers that what they buy is free from things that Muslims are not allowed to eat or drink under Islamic rules.
