Importers of Dimethyl Terephthalate (DMT) paid $25K in duties in August 2026, an effective tariff rate of 12.50% of the $197K imported — duty actually collected as a share of that value, not the published tariff schedule. Dimethyl Terephthalate (DMT) imports of $197K in August 2026 ran 15% above the year-to-date monthly average of $171K.
Last updated: August 2026 dataSouth Korea leads US imports of dimethyl terephthalate, followed by China and Japan — a supply concentration worth monitoring given that DMT is subject to Section 301 tariffs on Chinese-origin goods. DMT is a key aromatic diester used as an alternative to purified terephthalic acid (PTA) in the production of polyethylene terephthalate (PET) resins and polyester fibers. The entire heading resolves to a single 10-digit line, 2917370000, simplifying classification but not eliminating the need to verify country-of-origin documentation carefully when sourcing from multiple Asian suppliers.
