Mead Corporation v. United States
Whether a federal agency's interpretation of an ambiguous statute, issued through an informal ruling letter rather than through formal rulemaking or adjudication, is entitled to the strong judicial deference established under the Chevron doctrine.

In an 8–1 decision authored by Justice David H. Souter, the Supreme Court held that Customs Service ruling letters are not entitled to Chevron deference. The Court established an important new principle: an agency's interpretation of a statute receives Chevron deference only when Congress has delegated to the agency the authority to make rules carrying the force of law, and the agency's interpretation was issued in the exercise of that authority. This delegation is typically shown when an agency acts through formal adjudication, notice-and-comment rulemaking, or through some other procedure that Congress intended to give the resulting interpretation binding legal effect.
The majority reasoned that Customs ruling letters did not meet this standard. They were issued by any of 46 regional offices across the country without the kind of procedural safeguards — like public notice, opportunity for comment, or formal hearings — that signal Congress intended the resulting interpretation to bind the public. Ruling letters applied only to the specific transaction at hand, did not undergo review by higher agency officials before issuance, and could be reversed or modified at any time. The sheer volume of these letters — over 10,000 per year — further underscored that they were routine administrative decisions rather than exercises of delegated lawmaking power.
However, the Court did not say that such informal agency interpretations are worthless. Instead, it held that they may still receive a lesser, more flexible form of deference under the framework established in Skidmore v. Swift & Co. (1944). Under Skidmore, a court considers the thoroughness of the agency's reasoning, the consistency of its interpretation over time, the validity of its logic, and its specialized expertise. The weight given to the agency's view depends on its actual persuasiveness in the particular case.
The Court remanded the case back to the Federal Circuit, instructing it to evaluate the Customs Service's classification of Mead's day planners under this Skidmore standard rather than under the more deferential Chevron framework. The decision drew a significant line in administrative law, making clear that Chevron deference is not automatic simply because an agency is interpreting a statute it administers — the form and procedural context of the interpretation matters enormously.
Concurring Opinions
Justice Stephen Breyer wrote a brief concurrence emphasizing that the Chevron and Skidmore frameworks are best understood not as an either-or switch but as points on a spectrum of deference, and that the degree of judicial respect owed to an agency interpretation should depend on the practical circumstances and the likelihood that Congress intended the agency to have interpretive authority in the particular context.
Dissenting Opinions
Antonin Scalia
Justice Scalia argued that any authoritative agency interpretation of an ambiguous statute the agency is charged with administering should receive Chevron deference, regardless of the procedural format in which the interpretation is issued. He warned that the majority's approach created a confusing and unpredictable regime that would generate enormous litigation over whether any given interpretation qualifies for Chevron or the weaker Skidmore standard.
- The majority's test — asking whether Congress delegated authority to make rules with 'the force of law' — is vague and practically impossible for lower courts to apply consistently, replacing the clarity of Chevron with the open-ended uncertainty of the Skidmore sliding scale.
- The Skidmore standard is not really 'deference' at all but merely asks whether the agency's reasoning is persuasive, which is what judges would do anyway; the practical effect of the decision is to allow courts to substitute their own judgment for the agency's on a wide range of statutory questions.
- The decision would massively increase litigation costs and judicial workload, as parties would routinely challenge whether an agency's interpretive format qualified for Chevron, creating a threshold battle before the substantive question could even be addressed.
- Chevron's virtues — predictability, uniformity, and respect for agency expertise — are undermined when deference depends on whether the agency happened to use formal rulemaking rather than an equally authoritative but less formal mechanism.
Background & Facts
Mead Corporation was a company that imported small, loose-leaf daily planners into the United States. For years, the U.S. Customs Service had classified these planners as duty-free items under the Harmonized Tariff Schedule, placing them in the category of 'other' bound items. Then, in 2000, the Customs Service changed course. It issued a 'ruling letter' reclassifying Mead's day planners as 'bound diaries,' which carried a tariff duty of approximately 4 percent. This reclassification meant Mead would owe import taxes it had not previously been required to pay.
Ruling letters were a standard tool of the Customs Service. The agency's 46 regional Customs offices collectively issued between 10,000 and 15,000 of these letters each year. They were informal classification decisions issued to specific importers for specific products, and any particular ruling letter was binding only on the specific transaction it addressed. The Customs Service could modify or revoke them at any time. Importantly, these ruling letters were not produced through the formal notice-and-comment rulemaking process or through formal adjudication — the more structured procedures agencies sometimes use when issuing rules with the force of law.
Mead challenged the reclassification. The case went to the U.S. Court of International Trade, which upheld the Customs Service's decision. The Federal Circuit Court of Appeals reversed, however, finding that Mead's planners did not meet the definition of 'bound diaries.' In reaching its conclusion, the Federal Circuit declined to give the Customs Service's ruling letter the strong form of judicial deference known as Chevron deference, under which courts generally defer to an agency's reasonable interpretation of an ambiguous statute it administers.
The U.S. government, representing the Customs Service, asked the Supreme Court to hear the case. The central issue was not merely whether day planners qualified as diaries, but something far more fundamental to administrative law: under what circumstances should courts defer to an agency's interpretation of a statute? The Supreme Court agreed to take up the case because the question of when Chevron deference applies had become a recurring source of confusion and disagreement across the federal courts.
The Arguments
The government argued that the Customs Service's tariff classification ruling letters deserved Chevron deference because Congress had broadly delegated to Customs the authority to classify imported goods. Under this view, any authoritative agency interpretation of an ambiguous statute the agency administers should receive strong deference from the courts.
- Congress gave the Customs Service the explicit power to classify imported goods and fix their rates of duty, representing a broad delegation of interpretive authority.
- Customs ruling letters are the agency's authoritative position on the meaning of tariff terms, and importers rely on them in conducting their business.
- Denying Chevron deference to ruling letters would undermine the uniformity and predictability of tariff classifications, which the Customs system depends on.
Mead argued that Customs ruling letters were informal, case-specific administrative decisions that did not carry the force of law and therefore did not qualify for Chevron deference. The reclassification of its planners as 'diaries' was an unreasonable interpretation of the tariff schedule.
- Customs ruling letters are not produced through notice-and-comment rulemaking or formal adjudication, the procedures typically associated with binding legal rules.
- Ruling letters are issued by dozens of regional offices, are binding only on specific transactions, and can be changed at any time — they lack the hallmarks of authoritative legal pronouncements.
- Mead's day planners are not 'diaries' in any ordinary sense of the word, and the reclassification was an unreasonable stretch of the tariff category.
