Don't be fooled by cheap bulk cleaning products Standard treatment for criminals Director General of Standards of Tehran Province: The choice to buy a non-standard product is in the hands of the people themselves. A unique 10-digit tracking code is inserted under the standard national logo and symbol, and if the product does not have this 10-digit code under the standard symbol, the inserted symbol is definitely fake and invalid. Some underground and unauthorized producers try to deceive the public opinion with publicity tricks. They justify their cheaper product by claiming that they don't pay for the packaging. Recently, the supply of detergents in bulk and without packaging has started in the bazaar, and the General Directorate of Standards of Tehran Province has seriously entered this field to deal with it decisively.
