Investigation 731-TA-3899 is a U.S. International Trade Commission antidumping (AD) proceeding on Polytetramethylene Ether Glycol from China, South Korea, Taiwan, and Vietnam; Inv. No. 731-TA-1782-1785 (Preliminary) from Vietnam, South Korea, China, Taiwan. The ITC determines whether U.S. industry is materially injured (or threatened) by imports under investigation; Commerce determines whether dumping or subsidization is occurring. Both findings are required for an AD/CVD order to be issued.
731-TA-3899 is in the preliminary phase, with status active. Preliminary phase — the ITC's initial 45-day determination on whether there's a reasonable indication of injury. A negative preliminary terminates the investigation; an affirmative one moves it forward.
Not yet. 731-TA-3899 has not produced an AD/CVD order in Tandom's catalog. If both Commerce and the ITC issue affirmative final determinations, an order would issue and link to this investigation. Until then, no cash deposits apply.
