J. W. Hampton, Jr., & Co. v. United States
The Court upheld a law letting the President adjust tariff rates, within a fixed range, based on findings by a Tariff Commission about differences in production costs between the United States and foreign countries.
The ruling established that Congress can hand off this kind of fact-finding and rate-adjusting work to the President without unconstitutionally giving away its own lawmaking power, so long as Congress spells out a clear enough policy for the President to follow.
How it got here: The importer protested the duty; the Customs Court and then the Court of Customs Appeals upheld the law, and the Supreme Court granted certiorari after the Attorney General flagged the case's importance.
The Case in Depth
What happened
A company importing barium dioxide from Germany into New York was charged six cents per pound in customs duties, two cents more than Congress had originally set. The increase came from a presidential proclamation, issued after a Tariff Commission investigation found that the original rate did not equalize production costs between the United States and Germany, as a 1922 tariff law allowed.
The question before the Court
Could Congress let the President raise a tariff rate whenever a tariff commission found that foreign production costs were undercutting American manufacturers?
Why it matters
Importers and domestic manufacturers gained a durable answer to how much tariff-setting authority Congress could hand to the President: Congress can authorize the executive branch to adjust rates using expert findings, as long as lawmakers set clear boundaries in advance, a framework that later underpinned modern delegations of rulemaking authority to federal agencies.
What changes now
The Court's judgment made the disputed tariff increase final and confirmed the underlying statute as constitutional, so the importer owed the higher duty. More broadly, the decision became a lasting benchmark for how much authority Congress can delegate to the President and to federal agencies, provided Congress supplies a clear guiding standard for the delegate to follow.
What this does not decide
The Court did not decide that Congress can hand the President open-ended power to set tariffs or other rules however he sees fit; it upheld only a scheme where Congress fixed the guiding formula, capped the range of adjustment, and required a fact-finding investigation before any change took effect.
How the Court got there
The legal reasoning, step by step
- The Court framed the question as whether Congress had handed the President actual lawmaking power, or merely authorized him to carry out a policy Congress itself had already set — the core distinction in nondelegation doctrine.
- It explained that Congress may enlist the executive branch to fill in details or apply a law to changing facts, so long as Congress lays down an 'intelligible principle' to which the executive must conform; this is not forbidden delegation because the underlying policy choice was already made by Congress.
- The Court found that Congress had already made the policy choice here: duties should equalize the cost difference between producing goods in the United States and producing them abroad. The President's role was only to investigate the changing facts and apply that fixed formula, not to decide what the policy should be.
- It drew on precedent allowing similar arrangements — executive officers filling in regulatory details, and independent commissions setting utility and railroad rates according to a general standard set by the legislature — as consistent with the same principle.
- The Court also rejected the separate argument that a tariff cannot protect domestic industry, noting a longstanding, contemporaneous historical practice of using tariffs partly to encourage American manufacturing, dating to the very first tariff act in 1789, so long as raising revenue remained a legitimate purpose.
