Polytetramethylene Ether Glycol From the People's Republic of China, the Republic of Korea, Taiwan, and the Socialist Republic of Vietnam: Postponement of Preliminary Determinations in the Less-Than-Fair-Value Investigations

DATES:

Applicable August 28, 2026.

SUPPLEMENTARY INFORMATION:

Background

On April 28, 2026, the U.S. Department of Commerce (Commerce) initiated less-than-fair-value (LTFV) investigations of imports of polytetramethylene ether glycol (PTMEG) from China, Korea, Taiwan, and Vietnam. ⁽¹⁾ Currently, the preliminary determinations are due no later than September 15, 2026.

Postponement of Preliminary Determinations

Section 733(b)(1)(A) of the Tariff Act of 1930, as amended (the Act), requires Commerce to issue the preliminary determination in a LTFV investigation within 140 days after the date on which Commerce initiated the investigation. However, section 733(c)(1)(A)(b)(1) of the Act permits Commerce to postpone the preliminary determination until no later than 190 days after the date on which Commerce initiated the investigation if: (A) the petitioner makes a timely request for a postponement; or (B) Commerce concludes that the parties concerned are cooperating, that the investigation is extraordinarily complicated, and that additional time is necessary to make a preliminary determination. Under 19 CFR 351.205(e), the petitioner must submit a request for postponement 25 days or more before the scheduled date of the preliminary determination and must state the reasons for the request. Commerce will grant the request unless it finds compelling reasons to deny the request.

On August 20, 2026, the petitioner  ⁽²⁾ submitted a timely request that Commerce postpone the preliminary determinations in these LTFV investigations. ⁽³⁾ The petitioner stated that it requests postponement "so that Commerce can evaluate fully the initial questionnaire responses submitted by the mandatory respondents and solicit supplemental information as necessary."  ⁽⁴⁾

For the reasons stated above and because there are no compelling reasons to deny the request, Commerce, in accordance with section 733(c)(1)(A) of the Act, is postponing the deadline for the preliminary determinations by 50 days ( i.e., 190 days after the date on which these investigations were initiated). As a result, Commerce will issue its preliminary determinations no later than November 4, 2026. In accordance with section 735(a)(1) of the Act and 19 CFR 351.210(b)(1), the deadline for the final determinations of these investigations will continue to be 75 days after the date of the preliminary determinations, unless postponed at a later date.
