Did Trump Administration Declare Brass Instruments A National Security Threat
In August 2026, a rumor spread that the administration of U.S. President Donald Trump had declared brass musical instruments to be a national security threat to justify imposing tariffs on them.
The claim: In August 2026, the administration of U.S. President Donald Trump declared brass instruments a national security threat and imposed tariffs on them.
One Facebook post about the claim read:
Trump vs trumpets!
This week, the Trump administration declared tubas, trombones, trumpets, and French horns a national security threat.
Brass instruments could soon face a 25% tariff on imports, parts, and accessories, as part of a wider push to expand tariffs on aluminium, steel, and copper. The six-page proposal, published by the Department of Commerce, uses the words “national security” nine times.

Variants of the claim also spread on Reddit and on X.
The social media posts echoed reports in blog posts and news outlets, including the website of Classic FM, a radio station dedicated to classical music, and HuffPost.
Meanwhile, several curious readers emailed and searched the website seeking to verify the information.
It is true that on Aug. 6, 2026, the Department of Commerce published a request for comment on the Federal Register for a proposed rule to impose tariffs on brass instruments, among other products. The publication cited national security concerns.
However, it was not the instruments themselves the government department appeared to focus on, but the material from which they are made — a copper alloy. The request for comment cited Presidential Proclamation 10962 of July 30, 2025, in which Trump said copper “in all forms” — including its alloys — “is being imported into the United States in such quantities and under such circumstances as to threaten to impair the national security of the United States.”
As a result, we’ve rated the claim mostly true.
Background of the proposed tariffs
The request for comment featured a list of several products on which the Commerce Department proposed to impose tariffs. Besides “brass-wind musical instruments and parts and accessories thereof,” the list included fire extinguishers and oxygen tanks.
These imported products needed to be subjected to tariffs because they contained aluminum, steel or copper, the Commerce Department said. All three metals were the target of three separate presidential proclamations in which Trump deemed their importation excessive and a national security threat.
Proclamation 10962 specifically concerned copper “in all forms,” including alloys. The material for brass instruments is an alloy of copper and zinc, which presumably justified their inclusion in the list of imported products worthy of tariffs. The Commerce Department’s request for comment appeared to argue that imposing such tariffs helped protect domestic industries:
As explained in the reports submitted by the Secretary to the President and cited in Proclamations 9704, 9705, and 10962, steel, aluminum, and copper are being imported into the United States in such quantities or under such circumstances as to threaten to impair the national security of the United States. Therefore the President ordered adjustments of imports to protect U.S. national security interests by identifying derivative products on which tariffs must be imposed in order to protect the U.S. defense industrial base. The U.S. defense industrial base is critical to protecting U.S. national security interests.
The request for comment also said the Commerce Department would seek to impose 25% tariffs on these products, except for those deemed to be “agricultural equipment,” which would be subject to 15% duties.
By law, the Commerce Department cannot impose this rule before a period ending on Aug. 27, during which it will receive comments on its proposal.
