The US Trade Representative's Section 301 forced-labor tariffs, finalized on 23 July 2026, tie a country's rate directly to whether its economy formally prohibits imports made with forced labor. South Korea was placed in the 12.5% band rather than the 10% tier. For a cosmetics sector that now sends 20.7% of its exports to the US, this transforms raw-material supply chain documentation from routine corporate responsibility into a major tariff variable.
