Background on AD Investigations 

Antidumping duty (“AD”) is brought jointly by the U.S. International Trade Commission (“USITC”) and the U.S. Department of Commerce (“Commerce”). AD investigations are triggered when a domestic industry alleges that it has been injured by competing imports of particular goods from specific countries being sold at less than a fair value. The domestic industry initiating the investigation is known as the petitioner, while the foreign industry participating in the investigation is known as the respondent. 

Scope of the Investigation 

The merchandise covered by these investigations is all forms of polytetramethylene ether glycol (“PTMEG”).  

The products subject to the investigation are currently classified in the Harmonized Tariff Schedule of the United States (HTSUS) under the following subheadings: 3907.29.00 and 2932.11.00.   

Full scope here.

Next Steps 

The Commerce Department will determine whether to initiate the investigations within 20 days. The USITC will reach a preliminary determination of material injury or threat of material injury within 45 days. 

As with any proceeding, participation is very important to protect your rights. We urge anyone who imports Polytetramethylene Ether Glycol from China, South Korea, Taiwan, or Vietnam to pay close attention to this case and to ensure that all appropriate steps are taken to mitigate any damage. 

AD investigations can result in determinations adverse to respondent interests for years that could effectively prohibit access to the U.S. market. Failure to effectively participate in investigations can put exporters and importers at a significant disadvantage. 

Diaz Trade Law will continue to monitor this case and share updates.
