Mandatory disclaimer
government-mandated message in advertising

Mandatory disclaimers are government-mandated messages that describe what a product is not or does not do that sellers must include in their advertising.
In the United States, mandatory messages first appeared after the passage of the Federal Caustic Poisons Act (FCPA) of 1927, a law that ordered sellers of poisons to provide warning labels on their bottles. Prior to the passage of the FCPA, some sellers would use unusually shaped or colored bottles to signify the presence of a dangerous substance. After the Act, manufacturers mostly used plain bottles and displayed warning labels on them.
The agency responsible for enforcing the regulations of the FCPA was the Food and Drug Administration (FDA). Today, the FDA is the main body responsible for mandating disclaimers in the United States. Mandatory disclaimers are still used widely in the U.S.
The imposition of mandatory disclaimers is an exception to the First Amendment that was allowed by the Supreme Court of the United States in Valentine v. Christensen (1942). The exception to the First Amendment applies to commercial speech, which the Court defined as speech that “proposes a commercial transaction.”
Later cases have attempted to limit the extent of the “commercial speech" restriction on free speech, such as Virginia State Board of Pharmacy v. Virginia Citizens Consumer Council (1976) and Florida Bar v.
This brief starts where responsible research should: with the source description of “Mandatory disclaimer” as government-mandated message in advertising. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as government-mandated message in advertising. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Oct 4, 2016. The linked authority identifier is Q17130742. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1927, 1942 and 1976.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
