The article examines key aspects of the use of independent guarantees in contract law, particularly at the stage of bid submission by a procurement participant and within the framework of contract performance security. Special attention is paid to the role of the guarantee as one of the main instruments for risk mitigation in the system of public and corporate procurement. The place of independent guarantees in the modern public procurement system is analyzed, which represents a complex, multifaceted mechanism of legal regulation integrating the norms and principles of civil, administrative, financial, and budgetary law. It is emphasized that this institution serves not only a security function but also a stimulative one, promoting greater discipline among procurement participants. Particular focus is given to the validity period of independent guarantees, the need for its alignment with the contract performance period, and the potential legal consequences of non-compliance. Controversial situations related to the early termination of guarantees and their extension in case of changes to the performance deadlines are examined. Special emphasis is placed on the conflict-of-law aspects of applying independent guarantees arising from contradictions between civil and contract law. In particular, the absolute prohibition on revoking guarantees in public procurement, as well as the guarantor’s lack of right to refuse payment if the submitted documents formally comply with the guarantee terms, are analyzed. It is stressed that these restrictions stem from the public-law nature of procurement, which significantly limits the application of dispositive norms in civil law. In conclusion, the need for further improvement of legislation regulating independent guarantees is substantiated, including the standardization of requirements for their execution and content. The importance of establishing consistent judicial practice aimed at minimizing legal risks for all procurement stakeholders-customers, suppliers, and financial institutions-is highlighted. Possible directions for legislative reforms are proposed to enhance transparency and efficiency in the use of guarantees within the contract system.
