United States v. Mead Corp.
The Supreme Court ruled that a U.S. Customs Service letter classifying imported day planners for tariff purposes was not entitled to the strong, automatic deference courts give to formal agency rules, because Congress never showed it wanted these informal rulings to carry the force of law.
Instead, the Court said such rulings deserve a lesser, sliding-scale respect based on how careful and persuasive they are. The decision reshaped how courts nationwide decide which agency actions get strong deference and which get only modest consideration.
How it got here: The Court of International Trade sided with Customs; the Federal Circuit reversed, refusing to give the ruling Chevron deference; the government sought Supreme Court review.
The Case in Depth
What happened
The Mead Corporation imports day planners — three-ring binders with calendars and note pages. For years Customs treated these as duty-free, but in 1993 Customs Headquarters issued a letter reclassifying them as "diaries," subject to a tariff. Mead challenged the reclassification, arguing the planners didn't fit the "diary" category and that the ruling deserved no special judicial deference.
The question before the Court
When a federal agency issues a letter interpreting a law but doesn't use formal rulemaking or a formal hearing, must courts automatically accept that interpretation as long as it's reasonable?
The Court's answer
No — at least not automatically. The Court ruled that federal agencies only get the strongest form of judicial deference, known as Chevron deference, when there's a real basis for thinking Congress meant the agency's action to carry the force of law — for example, because Congress authorized formal rulemaking or formal hearings. Customs's day-planner classification letter didn't meet that bar: it bound only the specific importer, could be changed without notice, and was one of thousands issued yearly from dozens of offices with no public process.
That didn't leave the ruling with zero weight, though. The Court revived the older Skidmore v. Swift & Co. standard, under which a well-reasoned, careful, and consistent agency interpretation can still earn respect proportional to how persuasive it is — just not the automatic acceptance Chevron provides.

Why it matters
Every day, federal agencies issue guidance letters, opinion letters, and informal rulings without full rulemaking procedures. This decision tells courts, businesses, and agencies that such informal pronouncements generally won't get the strongest form of judicial deference — meaning courts, not agencies, often get the final say unless the agency used more formal procedures.
What changes now
The case returns to the Federal Circuit or the Court of International Trade, which must now decide, applying the Skidmore standard, how much weight to give the Customs ruling based on its thoroughness and reasoning rather than automatic deference. This is a final merits decision on the deference question, though the ultimate tariff classification of Mead's day planners remains to be resolved on remand.
What this does not decide
The Court did not decide whether Mead's day planners are actually "diaries" for tariff purposes — that question, along with how much persuasive weight to give Customs's reasoning under Skidmore, was left to the lower courts on remand.
Concurrences and dissents
Dissent — Justice Scalia
“Today's opinion makes an avulsive change in judicial review of federal administrative action.”Scalia's opening objection that the majority radically altered how courts review agency decisions.
Justice Scalia argued the majority abandoned the established Chevron framework, replacing a presumption that agencies may resolve statutory ambiguity with a presumption against agency authority unless Congress affirmatively said otherwise. He warned the new formal-procedure test was unworkable, would encourage agencies to over-use rulemaking, and would 'ossify' the law by locking in judicial interpretations that agencies could no longer revisit. He would have deferred to Customs's classification as the agency's authoritative, reasonable view and reversed the Federal Circuit outright.
How the Court got there
The legal reasoning, step by step
- The Court explained that Chevron deference — the strong form of deference under which courts accept any reasonable agency reading of an ambiguous statute — applies only when Congress can be understood to have delegated authority to the agency to issue rules or rulings carrying the force of law.
- Signs of that kind of delegation include the agency's authority to use formal procedures like notice-and-comment rulemaking or formal adjudication, though the Court noted these are not strictly required and other indications of congressional intent can suffice.
- Applying this framework, the Court found Customs's classification-ruling system lacked such signs: the letters aren't subject to notice-and-comment, bind only the specific importer involved, can be revoked without notice, and are issued in huge numbers (10,000 to 15,000 a year) from 46 different offices.
- Because nothing in the tariff statutes suggested Congress meant these letters to bind the public generally, the Court concluded Customs's ruling did not qualify for Chevron treatment.
- The Court then turned to Skidmore v. Swift & Co., holding that even without Chevron deference, an agency's reasoning can still earn a lesser, persuasion-based respect depending on its thoroughness, consistency, and expertise.
- Because the detailed Customs Headquarters letter might satisfy this Skidmore standard even though it failed the Chevron test, the Court sent the case back for the lower courts to make that persuasiveness assessment in the first instance.
