Preliminary finding: PTMEG sold below fair value

The period of investigation is April 1, 2025 through March 31, 2026, and this preliminary determination is effective November 10, 2026.
Company-specific dumping margins assigned
Commerce preliminarily assigned estimated dumping margins of 25.32 percent for Korea PTG Co., Ltd., 49.79 percent for BASF Company Ltd.

Suspension of liquidation and cash deposit rule
Effective on publication (November 10, 2026), U.S. Customs and Border Protection will suspend liquidation of PTMEG entries entered or withdrawn for consumption on or after that date.

Final determination postponed; provisional measures extended
At the request of Korea PTG Co., Ltd., Commerce postponed the final determination and extended provisional measures from four months to a period not greater than six months. Commerce will make its final determination no later than 135 days after the publication date of this preliminary determination.
