TheWorld Trade Organization (WTO)is the global body responsible for setting and enforcing the rules of international trade between nations. According to CLT 4.0, understanding international trade governance helps logistics professionals manage import/export documentation, tariffs, and compliance. The WTO facilitates trade negotiations, resolves disputes, and ensures transparent policies to maintain predictable trade flows across borders. It represents the majority of global trade participants—over 95% of world commerce. For U.S.-based logistics workers, the WTO’s policies influence how goods move internationally under agreements like GATT (General Agreement on Tariffs and Trade). By contrast, agencies like the DEA or State Department handle specialized or security functions, and CBP manages border enforcement, not global trade policy. Understanding WTO principles is crucial for CLT candidates to comprehend how trade regulations impact supply chain efficiency, tariffs, and global sourcing strategies.
