Practice Area
International trade is essential for the growth and development of global economies and businesses. As international trade has expanded and developed, so too have the myriad rules and regulations that govern it. The global compliance environment is becoming more complex by the day and can be difficult to navigate without the assistance of experienced counsel. Failure to comply with international trade rules and regulations—even if done so unwittingly—can lead to civil and criminal penalties, monitorships, consent agreements, debarment, reputational damage, substantial administrative burden, legal expense, and unsatisfied business objectives. Increasingly, there also is exposure for individual officers/directors, which can include monetary penalties and, potentially, jail time.

Export controls are a set of laws and regulations that govern the physical or electronic movement, transfer, or brokering of commodities, tooling, equipment, materials, software, technology, data, and services (collectively, “Items”), worldwide, to jurisdictions outside of a given country (example: non-U.S. jurisdictions), persons (individuals or entities) who are not a part of a given country (example: non-U.S. persons), and for prohibited end-uses. The term “export controls” can be misleading as export controls, particularly United States export controls, are extraterritorial and therefore apply also to reexports and transfers exclusively among and within non-U.S. jurisdictions.

Imports are goods that enter the customs territory of a given country after having been exported from a foreign destination. Imports and exports together represent foundational aspects of international trade. Therefore, they are often subject to trade agreements between jurisdictions, trade remedies that increase the cost of importing goods, and more cross-border considerations. In addition, countries may impose customs duties and/or tariffs, in other words taxes, on goods that enter the customs territory of a given country. Imports are fundamental to international trade and commerce. As such, legal issues arising from imports may implicate foreign policy, regulatory compliance, and cross-border transactions.
Law Glossary
Trans fats are ingredients found in food, which can be artificial or naturally occurring. Meat and milk products may contain naturally occurring trans fats. Artificial trans fat is made by adding hydrogen to vegetable oil. The liquid then becomes a solid at room temperature. Research has shown that eating trans fats can be linked to cardiovascular disease. In 2015, the FDA determined that the primary source of artificial trans fats, partially hydrogenated oils (PHOs), are not generally regarded as safe (GRAS). PHOs are in many processed foods.
