U.S. Department of Commerce Finds Korean Monomers and Oligomers Sold at Low Prices
Estimated reading time: 3–5 minutes
The U.S. Department of Commerce has announced its final decision regarding the sale of certain chemicals from Korea. These chemicals are called monomers and oligomers. They are important materials used in making different products.
The period that the Department looked at was from January 1, 2024, to December 31, 2024. They found that these chemicals were being sold in the United States for less than what they should cost. This is known as “less than fair value” or LTFV.
The investigation began on January 5, 2026, when the Department published its preliminary findings. They then extended these findings to be finalized by May 20, 2026. After reviewing further comments from interested parties, they finalized their determination that the chemicals were being sold at unfair prices.
Companies Involved
Several companies in Korea were part of this investigation. One of them is called Green Chemical Co., Ltd. This company and its affiliate were found to have sold products at unfair prices.
Another company involved is Miwon Specialty Chemical Co., Ltd. The Department found that it was using unfair pricing. As a result, they gave this company a high penalty rate of 155.42%.
Kukdo Chemicals Co., Ltd., another company, was also found to be selling at unfairly low prices. They received the same penalty rate as Miwon.
Scope of Investigation
The chemicals in question include various monomers and oligomers with different scientific names. These chemicals have uses in manufacturing other goods, but specific names were not changed during the investigation.
No changes were made to the scope of the investigation since its preliminary findings. The Department didn’t receive any comments on this from interested parties.
Final Decision on Critical Circumstances
The Department found that there were critical circumstances involved. This means that the imports of these chemicals were causing harm more quickly than usual. This finding applied to all companies involved, including others not directly examined.
Looking Ahead
As a result of these findings, the U.S. Customs and Border Protection will continue to hold these chemicals at the border. They will collect extra duties on them to protect U.S. businesses from being harmed.
The International Trade Commission will decide next if these low-priced imports are hurting U.S. industries. They have 45 days to make this decision.
If the Commission agrees with the Department, the duties will become official, and the U.S. will continue to monitor these imports closely.
This decision shows the government’s commitment to ensuring fair trade practices that protect American businesses and workers.
