Legal Definitions - interstate commerce

Interstate commerce refers to any commercial activity, trade, or movement of goods, services, money, or people that crosses state lines or significantly affects economic activity in more than one state.

Under the U.S. Constitution, specifically Article I, Section 8, Clause 3 (known as the Commerce Clause), the U.S. Congress is granted the power to regulate commerce "among the several states." This constitutional provision has been interpreted broadly by courts over time, allowing the federal government to regulate a wide range of activities that might seem local but ultimately have an impact on the national economy or trade between states. This broad interpretation ensures that economic activities that transcend individual state borders can be managed consistently across the nation.

Here are some examples of interstate commerce:

• Manufacturing and Distribution: A clothing company based in New York designs apparel, has it manufactured in factories in North Carolina, and then ships the finished garments to retail stores located in California, Texas, and Florida. The entire process, from sourcing materials to manufacturing and distributing products across state lines, constitutes interstate commerce. This allows federal agencies to regulate aspects like product safety standards, labor practices in the factories, or environmental impacts of the manufacturing process.

• Digital Services: A software development firm in Washington creates a subscription-based online platform for graphic design. Users from all 50 states, as well as international clients, subscribe to and utilize this service daily. Even though the company's physical operations are in one state, the delivery of its service and the financial transactions occur with customers located in many different states. This digital exchange of services and money across state lines falls under interstate commerce, enabling federal oversight on issues such as data privacy, cybersecurity, or consumer protection for online transactions.

• Professional Sports Leagues: A major professional football league organizes games between teams based in various states, with players and staff traveling across the country for competitions. The league also sells broadcasting rights to national television networks, and official merchandise is manufactured and distributed to fans nationwide. The movement of personnel, the sale of broadcasting services, and the distribution of goods all involve extensive activities that cross state borders, making the league's operations a clear example of interstate commerce subject to federal laws, such as antitrust regulations.
