Please do not follow what some people say at Qatar Living. They write for the sake of writing even if that means misguiding someone. Possibly, they drive some pleasure from this.
The item you plan to bring to Qatar is something people don't commonly bring with them when they come here. As such most people may not be aware of the rules on bringing in such items. Suggest you contact some cargo companies who may know the rules better or the Qatar embassy in your country.
