A new trade agreement between the US and Vietnam lowers tariffs on goods imported into US from Vietnam as the country of origin but keeps tariffs high if the goods are transshipped from China. Trade between China and Vietnam does not indicate significant transshipments for polyolefins and other products.
Although manufactured and semi-manufactured goods are more likely to be impacted by the additional tariffs on transshipments, there is relatively good agreement, allowing for transit and customs delays, between what China reports as exports to Vietnam and what Vietnam reports as imports from China, both yearend 2024 and April 2025 YTD. Further, the US imports minor volumes of the products below from Vietnam, except for PET.
