Main problem: It is very important for each company to obtain an industrial certificate, which makes it possible to get into the Register of Domestic Manufacturers, as they expect to receive large orders. With the receipt of an industrial certificate, their prospects for participation in various tenders and purchases will significantly increase, where they can show their abilities, compete with domestic producers, and also have an advantage over importers. Since July 1, 2019, the industrial certificate has become mandatory for participation in public procurement. Corresponding changes to the rules for public procurement were made by the Ministry of Finance of the Republic of Kazakhstan. Taking into account the experience of the «Rules for determining the country of origin of goods, issuing a certificate of origin of goods and canceling its validity», approved by Order of the Acting Minister for Investment and Development of the Republic of Kazakhstan dated February 24, 2015. No. 155», it becomes clear that the document does not take into account a number of «narrow» specifics of individual industries. Purpose: development of amendments and additions to the «Rules for the formation and maintenance of the register of domestic producers of goods, works and services, as well as the issuance of an Industrial Certificate» for the subsequent possibility of obtaining an Industrial Certificate by a chemical industry enterprise for the production of mineral fertilizers. Methods: study and analysis of literary sources, statistics and modeling of the procedure for issuing an Industrial Certificate. Results and their significance: the problems of application were studied, ways to solve these problems were found, and amendments and additions to the “Rules for the formation and maintenance of the register of domestic producers of goods, works and services, as well as the issuance of an industrial certificate” were developed. At the moment, the Rules need to be carefully finalized. It is necessary to consider this issue together with authorized state bodies, associations and business representatives, since obtaining an Industrial Certificate will directly affect participation in public procurement, and, accordingly, the economy of the Republic of Kazakhstan.
