Which department works with trade and industry?

The Department of Commerce is primarily responsible for promoting and regulating trade and industry in the United States. Its mission includes fostering economic growth, job creation, and opportunity by ensuring fair and open competition in international and domestic markets. The department oversees various agencies that focus on trade policies, economic development, and statistical information, which directly supports businesses and industries in their endeavors.

In contrast, the Department of Energy focuses on energy policies, research, and improvements related to national energy production and consumption. The Department of State is responsible for international relations, foreign policy, and diplomacy, which do not specifically pertain to trade and industry functions. The Department of Defense is concerned with national security and military affairs, with no direct focus on trade or industry matters.
