In export controls, what is a significant limitation of the U.S. Customs and Border Protection?

The correct answer identifies a key limitation of U.S. Customs and Border Protection (CBP) in the context of export controls. While CBP plays a crucial role in regulating international trade and enforcing laws, it does not have a dedicated program specifically for export controls. Instead, it acts as one of several agencies involved in export compliance and regulation.

The U.S. government relies on other entities, such as the Bureau of Industry and Security (BIS) and the Directorate of Defense Trade Controls (DDTC), to establish and enforce export controls. These agencies specifically focus on the export of sensitive goods, technologies, and information. Since CBP's primary function is to manage border security, customs enforcement, and trade facilitation rather than specifically overseeing export controls, this points to its limitation in that area.

This understanding illuminates the structure of U.S. export regulations, where multiple agencies have overlapping roles, but CBP does not specifically oversee the licensing or control processes related to exports. The other options pertain to functions that CBP does perform but do not highlight its limitation as effectively.
