What Is Interstate Commerce?

Interstate commerce refers to any commercial transactions or traffic that cross state boundaries or involve more than one state.

This concept is key to understanding the scope of regulatory powers, particularly those of the federal government in the United States, as granted by the Commerce Clause of the U.S. Constitution.

Interstate commerce includes a wide range of economic activities, such as the movement of goods, services, and people between states, as well as transactions conducted across state lines via mail or electronic means.

Interstate Commerce Explained

The regulation of interstate commerce is primarily a federal responsibility, underpinning the legal basis for much of the U.S. government's regulatory authority in areas ranging from environmental protection to consumer safety and civil rights.

The Commerce Clause enables the federal government to regulate interstate commerce to ensure a stable and uniform regulatory environment across state borders, preventing individual states from enacting laws that could disrupt the flow of commerce among them.

Activities considered to be part of interstate commerce include:

Shipping or transporting goods across state lines.

Selling or buying services where the provider and recipient are in different states.

Operating businesses that affect the flow of goods and services between states, even if the business itself does not directly cross state lines.

The Term Interstate Commerce in Different Legal Contexts

Business and Economic Regulation: Federal agencies, such as the Department of Transportation and the Federal Trade Commission, rely on the Commerce Clause to regulate businesses and economic practices that impact interstate commerce.

Labor Laws: Federal labor laws, including minimum wage and workplace safety standards, are applied to businesses involved in interstate commerce.

Environmental Regulations: Many federal environmental laws are justified under the Commerce Clause as they relate to pollutants that cross state boundaries and affect interstate commerce.

Common Misconceptions About the Meaning of Interstate Commerce

Only Involves Physical Goods: While the transportation of physical goods is a major aspect of interstate commerce, the term also encompasses services, financial transactions, and digital commerce that cross state lines.

Strictly Limited to Transactions Crossing State Lines: The impact of a commercial activity on interstate commerce, not just the physical crossing of state lines, can bring an activity within the scope of federal regulation. For example, a local business that significantly affects the flow of interstate commerce can be subject to federal laws.

State Governments Cannot Regulate Interstate Commerce: While the federal government has primary authority, states may regulate aspects of interstate commerce within their borders, provided their laws do not conflict with federal regulations or unduly burden interstate commerce.
