The second paragraph of Article 32 of the Regulations for the Implementation of the Bidding Law stipulates that "if a tenderer commits one of the following acts, it will restrict or exclude potential bidders or bidders with unreasonable conditions; 5) Restrict or designate specific patents, trademarks, brands, countries of origin or suppliers ". According to the existing laws and regulations, if bidding is adopted, brands may not be specified or restricted in the bidding documents, otherwise it is illegal.
This project is a project that does not need bidding according to law. If it is really necessary to restrict the brand, it is recommended to adopt the non-tendering method to implement the procurement.
