International supply chains operate through efficient and secure processes, especially regarding the location and conditions under which the delivery of goods subject to sale will occur. To delineate their respective obligations, companies engaged in international transactions rely on a standardized set of terms and regulations known as the Incoterms rules. The International Chamber of Commerce (ICC) regularly revises and issues these rules to keep them current with industry practices. This manual explains in a didactic manner the effective use of the Incoterms 2020 rules and provides criteria for choosing the most appropriate rule for each sales transaction. The author offers valuable insights to minimize business risks, optimize costs, and facilitate operations in international markets. This book is aimed at professionals in international trade and freight transportation, as well as those involved in training in these fields. It includes examples, practical cases, and self-assessment tests to strengthen training and professional performance.
