What are the procedures and problems of international trade?

International trade involves several procedures, including customs clearance, documentation (such as bills of lading and invoices), and compliance with various regulations and tariffs. Key problems include trade barriers like tariffs and quotas, currency fluctuations, and logistical challenges such as transportation and supply chain disruptions. Additionally, differences in legal systems and standards can complicate transactions. These factors can lead to increased costs, delays, and potential disputes between trading partners.
