Washington DC, US – A month after it opened an investigation into the alleged dumping of MDI from China on the US market, the US International Trade Commission (USITC) has determined there is justification to continue investigations.
After looking at imports into the country during the second half of 2024, USITC has decided there are reasonable grounds to consider that US industry is materially injured by reason of imports of MDI from China that are allegedly sold in the US at less than fair value from China. This follows a petition from the Ad Hoc MDI Fair Trade Coalition asking for antidumping duties to be imposed on US MDI imports from China.
Chair Amy Karpel and commissioners David Johanson and Jason Kearns voted in favour of further investigations. A preliminary antidumping duty ruling is set for 22 July 2025.
Methylene Diphenyl Diisocyanate from China, a public report by the Commission, will be available by 5 May 2025 on the USITC website.
Last year, the US imported about 229kT of MDI from China. This is currently subject to a 35% tariff, with an additional 10% being imposed at the start of February on top of the 25% introduced in May 2019. Very little MDI goes in the other direction, where it faces a 25% tariff plus the regular 6.5% import duty.
