On April 8, 2026, BASF Corporation (“Petitioner”), filed a petition for the imposition of antidumping duties on the import of polytetramethylene ether glycol (“PTMEG”) from China, South Korea, Taiwan, and Vietnam.
SCOPE OF THE INVESTIGATION
The proposed scope of these investigations is as follows:
The merchandise covered by this investigation is polytetramethylene ether glycol (“PTMEG”), which is a polymer consisting of linear diols (i.e., organic chemical compound that has two hydroxyl (-OH) functional groups) with a molecular backbone of repeating tetramethylene units (-CH₂CH₂CH₂CH₂-) interconnected through ether bonds (i.e., a single oxygen atom bonded to two carbon atoms), with a chemical formula HO{(CH2)4}nOH. PTMEG is also referred to as Polytetrahydrofuran, PTHF, Polytetramethylene ether glycol, PTMG, and Polybutylene glycol. PTMEG is typically blended with butylated hydroxytoluene (“BHT”) or another stabilizer. PTMEG is normally associated with Chemical Abstracts Service (“CAS”) registry number 25190-06-1.
The scope includes all forms of PTMEG, regardless of physical form, purity, molecular weight, number of hydroxyls, number of acids, color, density, softening point, glass transition point, flash point, water content, viscosity, and packaging. PTMEG that has been blended with other products is included within this scope when such blends include constituent parts that have been intermingled but that have not been chemically reacted with each other to produce a different product. For such blends, only the PTMEG component of the mixture is covered by the scope of these investigations.
The scope includes merchandise matching the above description that has been processed in a third country, including by commingling, diluting, introducing, or removing stabilizers, modifiers, or additives, or performing any other processing that would not otherwise remove the merchandise from the scope of the investigations if performed in the subject country. The scope also includes PTMEG that is commingled or blended with PTMEG from sources not subject to these investigations. Only the subject component of such commingled products is covered by the scope of these investigations.
The subject merchandise is classifiable in the Harmonized Tariff Schedule of the United States (“HTSUS”) under subheading 3907.29.00. Subject merchandise may also be imported under HTSUS subheading 2932.11.00. Although the HTSUS subheading and CAS registry number are provided for convenience and customs purposes, the written description of the scope is dispositive.
