U.S. delays tariffs on aircraft and jet parts, opts for negotiations first

The U.S. will not immediately impose tariffs on commercial aircraft, jet engines, and related parts despite a Section 232 investigation concluding that such imports pose a national security threat. President Donald Trump signed a proclamation on July 9, 2026, directing the U.S. Trade Representative and the Commerce Department to negotiate with trading partners to adjust imports of these products. Commerce Secretary Howard Lutnick’s report cited concerns over foreign subsidies, predatory trade practices, and the potential for foreign industries to weaponize control over commercial aircraft and jet supplies. The investigation, launched in May 2025 under Section 232 of the Trade Act of 1974, sought comments on the impact of foreign government subsidies and predatory trade practices affecting U.S. industry competitiveness. While the administration is pursuing negotiations, Trump warned that tariffs or other actions could still be imposed within 180 days if agreements are not reached or prove ineffective. The U.S. has also investigated roughly a dozen other sectors, including steel, semiconductors, and critical minerals, under similar Section 232 probes.
