The article analyzes the impact of the introduction of standardization and voluntary certification to improve the quality of veterinary medicines, feeds, feed additives and premixes. In terms of increased competition, both domestic and global markets, you need to look for new ways to improve the quality of products for veterinary medicine and animal husbandry. The competitiveness of the enterprise depends, first of all, on the ability of the business entity to meet the needs of consumers at relatively minimal cost. In improving the quality of veterinary products, a particularly important role is played by its standardization and certification, the basic legal and organizational principles of which are regulated by the Law of Ukraine «On Standardization». However, companies that carry out standardization of products, in addition to the aforementioned law, should be guided more by such regulations: the Law of Ukraine «On veterinary medicine», SOU KZPS 74.9-02568182-003:2016 «Guidelines for typical construction, layout, design, marking, acceptance and giving effect», State Classifier of products and services DK 016:2010.
 On January 1, 2018, the Decree of the Cabinet of Ministers of Ukraine «On Standardization» № 46-93 expired and the State Certification System of Ukraine (UkrSEPRO system) suspended its activities. However, the UkrSEPRO system certificate was replaced by a voluntary certificate of conformity issued by the accredited National Accreditation Agency of Ukraine (NAAU) in accordance with the requirements of the international standard DSTU EN ISO/IEC 17065:2017 «Conformity assessment. Requirements for certification agencies for products, processes and services».
 The basis of voluntary standardization and certification of veterinary products and products for the needs of animal husbandry is the confirmation of the manufacture of quality and safe products that will ensure its competitiveness in domestic and foreign markets.
