Case Closure Based on Settlement
On April 22, 2025, the United States International Trade Commission (USITC) announced a partial final ruling regarding investigation code 337-TA-1439, involving Certain Polyvinylidene Fluoride (PVDF) Resins.
The ITC decided not to review the initial determination made by the administrative law judge on April 1, 2025, meaning the investigation against Chinese company Inner Mongolia 3F Wanhao Fluorochemical Industry Co., Ltd. (Inner Mongolia 3F) was terminated based on settlement.
This marks the formal end of proceedings against Inner Mongolia 3F regarding alleged violations of Section 337 of the Tariff Act.
Background on the Investigation
The investigation had been initiated based on a complaint filed by:
- Syensqo SA (formerly Solvay’s specialty polymer division)
- Solvay Specialty Polymers USA LLC
- Solvay Specialty Polymers Italy S.P.A.
These companies accused Inner Mongolia 3F and other Chinese firms — including Zhejiang Juhua Co., Ltd., Zhejiang Foran New Materials Co., Ltd., Hubei Foran New Materials Co., Ltd., and Sinochem Lantian Co., Ltd. — of unfair trade practices related to the importation of PVDF resins into the U.S.
Export Perspectives
China is a major global supplier of PVDF resins, especially for applications in lithium-ion batteries and advanced coatings.
Key export markets for Chinese PVDF include the United States, South Korea, Japan, and Europe.
Following tighter trade regulations, many Chinese PVDF producers are pivoting towards Southeast Asian and domestic markets.
Competitor Analysis
Syensqo SA (formerly part of Solvay Group) remains a dominant player in high-performance PVDF, along with other multinational groups like Arkema and Kureha.
Chinese manufacturers such as 3F Wanhao, Juhua, and Foran are expanding capacity aggressively but face increasing regulatory and trade hurdles internationally.
Company Dynamics
Inner Mongolia 3F Wanhao Fluorochemical Industry Co., Ltd. is a key Chinese fluorochemical producer specializing in high-end fluoropolymers, refrigerants, and intermediates.
Following the termination of the U.S. investigation, the company is expected to refocus efforts on growing its domestic and Asian export businesses while addressing patent compliance and sustainability pressures.
