South Korea Faces New US Tariffs in 2026: Section 301 and Metal Duty Changes Explained

Listeners, South Korea is in the middle of a fast-moving U.S. tariff story as the Trump administration pushes a fresh wave of trade measures in June 2026. According to Dorsey’s client alert, the Office of the U.S. Trade Representative announced proposed Section 301 tariffs after an investigation tied to forced-labor policies and practices, with rates set at 10% for most goods from 15 trading partners and 12.5% for most goods from 45 trading partners. Dorsey also reports that the public comment period runs through July 6, 2026, followed by a public hearing on July 7. For South Korea specifically, HK Law reports that South Korea is one of the partner economies eligible for a reduced maximum combined duty of 15% on certain aluminum, steel, and copper derivative products under President Trump’s June 1 proclamation. That matters because the proclamation also resets some metal tariff rules and gives favored treatment to several allied economies, including South Korea, Japan, the United Kingdom, Taiwan, and European Union member states. The broader backdrop is a tougher tariff environment. HK Law says the June 1 action follows Trump’s earlier April 2 proclamation expanding Section 232 duties on aluminum, steel, and copper. Nixon Peabody reports that tariff uncertainty remains high into 2026, with businesses still dealing with shifting costs and trade compliance risks. In other words, South Korea is not facing a single isolated measure, but a layered tariff regime that could affect metals, manufacturing inputs, and downstream exports to the U.S. Listeners should watch three things closely: whether the proposed Section 301 tariffs move forward, how the administration finalizes the Section 232 metal rules, and whether South Korean exporters can continue to benefit from the partner-economy cap on certain duties. If implemented as proposed, these policies could reshape pricing, sourcing, and competitiveness for South Korean goods in the American market. Thank you for tuning in, and please subscribe.
