Yes, price labelling is a legal requirement for suppliers in Qatar. Under Article 8 of the Consumer Protection Law (Law No. 8 of 2008), every supplier who displays a commodity for sale must clearly label it with the price or conspicuously advertise the price at the location where the commodity is displayed. Consumers are entitled to pay only the displayed price and cannot be charged more than what is shown.
This rule applies across retail stores, supermarkets, and other commercial outlets. If you find that a product has no price tag or that you are being charged more than the displayed price at the till, this is a direct violation of Qatari consumer law and you have the right to challenge it.
If a shop refuses to honor the displayed price or fails to label products correctly, you can report the violation to the Ministry of Commerce and Industry. Suppliers found in breach of these provisions can face penalties under Article 18 of the law, which includes fines for violations. Always check your receipt against the displayed price before leaving a store.
