Definition
To "introduce into commerce of the United States" (often shortened to "introduce into commerce" or "place into commerce") means to bring a product, substance, or article into the stream of commercial distribution within or affecting United States markets for the first time — typically by sale, offer for sale, delivery for introduction, or shipment in commerce. The phrase functions as a regulatory trigger: once a product is "introduced into commerce," federal oversight mechanisms attach.
The concept appears most prominently in federal consumer protection, environmental, food and drug, and product safety law. The moment of introduction is legally significant because it marks the point at which a manufacturer, importer, or distributor becomes subject to premarket notification requirements, labeling mandates, recall authority, liability exposure under federal statute, or civil penalty provisions.
The phrase typically encompasses:
1. The first sale or offer for sale of a product to a purchaser in the United States.
2. Importation into U.S. territory for purposes of commercial distribution.
3. Initial shipment of a product through channels of interstate commerce.
The precise definition varies by statutory context. Under the Toxic Substances Control Act (TSCA), for example, "introduce into commerce" includes manufacturing for commercial purposes, processing, and distribution. Under the Federal Food, Drug, and Cosmetic Act (FDCA), comparable language governs when devices and drugs become subject to premarket approval. The Consumer Product Safety Improvement Act (CPSIA) uses the phrase to determine when testing and certification obligations arise for manufacturers and importers.

Common Language
Modern common usage (Wiktionary): "Introduce" means to bring something into use or notice for the first time; "commerce" means trade or business activity involving the exchange of goods or services.
Historical common usage (Webster's 1913): "Introduction" — the act of making known; also, the first part of a book or discourse. "Commerce" — interchange of goods, productions, or property of any kind; trade.
The ordinary meaning of "introduce" suggests novelty — a first appearance. The legal phrase preserves that sense but attaches it to a specific regulatory moment rather than mere novelty. Critically, in regulatory law the phrase does not require that a product be new to the world, only that it be entering U.S. commerce for the first time under the conditions defined by the applicable statute. A product already sold abroad may still be "introduced" into U.S. commerce upon importation.

Common Confusion
Researchers frequently conflate "introduce into commerce" with "manufacture" or "distribute in commerce." These are related but distinct statutory concepts. A manufacturer may produce goods without yet having introduced them into commerce (e.g., goods held in a warehouse awaiting sale). Conversely, a distributor or importer — not the original manufacturer — may be the party that legally "introduces" a product into U.S. commerce. The responsible party for regulatory compliance purposes often turns on which statutory definition of "introduction" applies and who performs that triggering act first.

Why It Matters in Research
This phrase is a term of art that does not exist in common law but is pervasive in federal regulatory statutes enacted primarily in the twentieth century. Researchers working in pre-New Deal sources will not encounter it in its modern regulatory sense; historical sources treat "introduction" in a rhetorical or procedural context (see Historical Dictionary Support below).
Key research traps:
— **Statute-specific definitions control.** The phrase is not uniformly defined across federal law. TSCA's definition, CPSIA's definition, and FDCA's operative language all differ in scope and in who bears the obligation. Never assume that a judicial interpretation under one statute resolves the question under another.
— **Importer liability.** A significant area of litigation concerns whether importers "introduce" products into commerce in the same manner as domestic manufacturers. Regulatory agencies have taken expansive positions; courts have not always agreed. Researchers should track agency guidance documents alongside case law.
— **Timing questions.** Whether introduction has occurred — and when — determines which version of a regulatory standard applies. This is particularly acute in product safety and environmental law, where standards change and grandfather provisions may shield products introduced before a compliance date.
— **Corpus connections.** This term links directly to federal preemption doctrine (state law claims vs. federal regulatory standards), strict liability in products liability contexts, and customs and import law. A full research picture requires tracing all three threads.

Historical Dictionary Support
Bouvier's Law Dictionary does not define "introduce into commerce of the United States" as a legal term. The entry under "Introduction" addresses only the structural part of a legal document — the preliminary recitals or factual background that frame a written instrument. This usage is entirely distinct from and predates the regulatory phrase by more than a century.
This gap is instructive. The absence of the regulatory phrase from Bouvier's reflects the pre-administrative-state character of nineteenth-century American law. Commerce regulation existed — the Commerce Clause was a live constitutional battleground — but the granular regulatory question of when a product "enters" commerce as a trigger for federal oversight did not arise in its modern form until the New Deal era and the explosion of product-specific regulatory statutes in the 1960s and 1970s.
Researchers using Bouvier's or similar period dictionaries for this phrase will find nothing of value for the modern regulatory meaning. The historical sources simply do not address it.

Jurisdictional Note
This is a federal concept with no direct state-law analog, though state consumer protection and environmental statutes occasionally borrow similar language. Jurisdictional variation arises primarily through federal circuit court interpretations of agency definitions and through the scope of federal preemption, which determines how much room state law has to operate once federal "introduction into commerce" standards apply.
