Which of the following agencies is NOT one of the four key US agencies for Export Controls?

The correct answer is the US Department of Labor, as it is not directly involved in the export control process. The key agencies for export controls in the United States focus on regulating and monitoring the export of goods, services, and technology to ensure national security and compliance with international agreements.

The US Department of Commerce plays a crucial role through its Bureau of Industry and Security (BIS), which manages the Export Administration Regulations (EAR) and oversees the export of dual-use items that can have both civilian and military applications.

The US Department of State is involved primarily through the Directorate of Defense Trade Controls (DDTC), which administers the International Traffic in Arms Regulations (ITAR) to control the export of defense-related articles and services.

US Customs and Border Protection is responsible for enforcing laws related to trade, including exports. They play a critical role in monitoring the movement of goods across borders to ensure compliance with export regulations.

In contrast, the US Department of Labor focuses on issues related to labor standards, workforce development, and occupational safety, which do not pertain to export controls, thereby making it the agency that is not part of the four key US agencies for export controls.
