U.S. Issues Final Duties on Monomers and Oligomers from Taiwan
Estimated reading time: 3–6 minutes
Date: 2026-02-03
On February 3, 2026, the U.S. Department of Commerce (Commerce) announced a final affirmative determination in its investigation into imports of certain monomers and oligomers from Taiwan.
Commerce found that these products are being, or are likely to be, sold in the United States at less than fair value (LTFV). It also made a final affirmative determination that critical circumstances existed.
The period of investigation was January 1, 2024, through December 31, 2024.
BACKGROUND
Commerce issued a preliminary determination on September 9, 2025. This was published in the Federal Register at 90 FR 43409. Interested parties were given a chance to comment.
Due to a Federal Government shutdown, Commerce extended deadlines in all administrative proceedings by 68 days. The final determination deadline was set to January 28, 2026.
The Issues and Decision Memorandum contains the full discussion of the facts and decisions. This memorandum is available at https://access.trade.gov/public/FRNoticesListLayout.aspx.
SCOPE
This investigation covers certain multifunctional acrylate and methacrylate monomers and acrylated bisphenol-A epoxy based oligomers. These substances are created using acrylic or methacrylic acid.
A full list of the specific chemical names and CAS numbers is provided in Appendix I of the notice.
There were no changes to the scope from the preliminary determination. No interested party commented on the scope.
ADVERSE FACTS AVAILABLE (AFA)
Eternal Materials, Qualipoly, and Synth-Edge did not participate in the investigation. Therefore, Commerce assigned them a dumping margin based on adverse facts available under sections 776(a) and (b) of the Tariff Act.
Commerce also applied AFA rates to these firms in its preliminary findings. No new details were submitted that changed this decision.
All “other” producers and exporters were assigned a dumping margin based on a simple average of the petition rates.
CRITICAL CIRCUMSTANCES
Commerce determined that critical circumstances exist for the named companies and all other producers/exporters. Commerce used adverse facts available in making this finding for the mandatory respondents.
ALL-OTHERS RATE
Since all dumping margins were based on AFA, Commerce applied the simple average of the margins alleged in the petition to “all others.” This rate is 130.23 percent.
FINAL DUMPING MARGINS
Commerce assigned the following final estimated weighted-average dumping margins:
- Eternal Materials Co., Ltd.: 130.23%
- Qualipoly Chemical Corporation: 130.23%
- Synth-Edge Advanced Material Co., Ltd.: 130.23%
- All Others: 130.23%
SUSPENSION OF LIQUIDATION
Commerce instructed U.S. Customs and Border Protection (CBP) to suspend liquidation of entries of the goods subject to this investigation which entered U.S. commerce on or after June 11, 2025. This is 90 days before the preliminary determination.
For entries on or after January 7, 2026, when provisional measures ended, suspension of liquidation will stop unless the International Trade Commission (ITC) makes a final affirmative injury determination.
If the ITC determines that injury exists, Commerce will issue an antidumping duty order. If the ITC determines there is no injury, the proceeding will be terminated and all deposits will be refunded.
EXPORT SUBSIDY OFFSET
No countervailable export subsidies were found in the companion countervailing duty investigation. Therefore, Commerce did not adjust the cash deposit rates for export subsidies.
ITC ROLE
If the ITC makes a final determination of material injury, Commerce will impose a duty order. The ITC has 45 days from the final determination to make its decision.
APO REMINDER
If the ITC issues a negative injury determination, Commerce reminds parties to comply with administrative protective order (APO) procedures, including destruction of proprietary data.
ADMINISTRATIVE DETAILS
This action was signed by Christopher Abbott, Deputy Assistant Secretary for Policy and Negotiations.
The final determination was issued in accordance with sections 735(d) and 777(i)(1) of the Tariff Act of 1930, as amended.
