US Cuts Tariffs on South Korean Imports to 15%, Retroactive to November 1

The United States has officially reduced the tariff rate on imports from South Korea to 15%, applicable retroactively from November 1, as per the news reports.  

This move follows South Korea’s legislative push to uphold its commitment to invest $350 billion in key American industries.  

Why Did US Reduce Tariffs on South Korean Imports to 15%? 

On December 1, 2025, US Commerce Secretary Howard Lutnick confirmed that the tariff rate on South Korean imports, including automobiles, has been adjusted to 15%, effective from November 1.  

Previously, these imports were subject to a 25% rate. The US has also eliminated tariffs on airplane parts and aligned South Korea's reciprocal trade rate with Japan and the EU. 

This move follows South Korea’s submission of legislation in its parliament to support a $350 billion investment across various American sectors, including shipbuilding and technology. 

Impact on Automotive and Key Sectors 

The reduction in auto tariffs is one of the most significant aspects of this trade adjustment. It brings South Korea to parity with Japan and other strategic partners under the restructured agreement.  

Furthermore, a cap has been introduced on national security tariffs applicable to semiconductors and pharmaceuticals, limiting them to 15%. 

Strategic Significance in Global Trade 

The revised deal showcases the mutual economic importance both nations place on their strategic partnership. Officials emphasised that this change reinforces South Korea’s role as a stable and integral player in the global supply chain, particularly in high-value segments like semiconductors and shipbuilding.
