Incoterms, as the global standard for defining responsibilities and obligations related to the transportation and delivery of goods in international trade, play a fundamental role. This set of rules clearly specifies the responsibilities of sellers and buyers at each stage of the goods transportation process, including cost allocation, risk management, and the preparation of documents related to goods delivery. Each new version of Incoterms is updated and revised in response to the growing needs of global trade and the complexities of supply chains. This paper comprehensively examines the key changes introduced in the principles of Incoterms from the earlier versions to the latest one, Incoterms 2020, and provides a thorough comparison of the differences between Incoterms 2010 and 2020. With a particular focus on the significant changes in these two versions, the paper analyzes aspects such as amendments to delivery terms, changes in insurance responsibilities for sellers and buyers, and the emphasis on safety and security requirements. The aim of this paper is to clarify the strengths and weaknesses of each version of Incoterms and to assess the impact of these changes on global trade, particularly in the field of logistics and international transportation. Changes such as the replacement of terms, increased insurance responsibilities under specific conditions, and greater emphasis on safety and security requirements to facilitate trade and reduce risks associated with goods delivery are among the key points discussed in this paper.
