Yes, Arabic is legally required on product labels and service information in Qatar. Article 17 of the Consumer Protection Law (Law No. 8 of 2008) states that all product information, pricing, and service details required under the law must be provided in Arabic. Other languages, such as English, may also be included alongside Arabic, but they cannot replace it.
This means that under Article 7, the type, nature, ingredients, and other relevant commodity information displayed on packaging must appear in Arabic. Similarly, service descriptions and pricing under Article 11 must be in Arabic. If a product you purchased has no Arabic labelling at all, it may not be legally compliant for sale in Qatar.
As an expat, if you encounter a product with only foreign-language labelling, you are within your rights to request clarification from the supplier, and the absence of Arabic labelling could be grounds for a complaint to the Ministry of Commerce and Industry. On a practical note, for health and safety reasons — especially for food, medicine, and chemical products — always try to verify ingredients and usage instructions before purchasing. Retailers and pharmacies in Qatar are generally accustomed to helping English-speaking customers understand product details.
