Proclamation Declares Commercial Aircraft Imports a National Security Threat

President Trump signed a proclamation on July 9, 2026, formally concurring with a Commerce Department finding under Section 232 of the Trade Expansion Act of 1962 that imports of commercial aircraft, jet engines and their associated parts "threaten to impair the national security of the United States." The proclamation cites foreign trade practices, overreliance on foreign supply chains, and counterfeit or non-compliant imported parts. On the Secretary's recommendation, it imposes no immediate tariffs; instead it directs the Commerce Secretary and the U.S. Trade Representative to negotiate agreements with trading partners and to report back within 180 days, while reserving that the President "may consider alternative remedies in the future."

Section 232 is a national security authority, and this administration has used it repeatedly to reach sectors of the economy, including automobiles, semiconductors and critical minerals. Because the finding of threatened impairment is now on the record, tariffs on aerospace goods can be imposed later without a new investigation. The action also comes after courts invalidated the administration's IEEPA-based global tariffs, making Section 232 a more durable legal vehicle for trade measures.

The proclamation is in effect. No tariff rates have been set, and the first status report on negotiations is due within 180 days.
