USITC Finds Injury to U.S. Industry From Chinese Imports of Sol Gel Alumina-Based Ceramic Abrasive Grains
Estimated reading time: 3–5 minutes
On September 19, 2025, the United States International Trade Commission (USITC) made a final determination about imports from China. The USITC found that an industry in the United States is materially injured by imports of sol gel alumina-based ceramic abrasive grains from China.
These grains are listed under subheading 2818.10.20 of the Harmonized Tariff Schedule of the United States. The Department of Commerce found that these imports from China are being sold in the U.S. at less than fair value and are subsidized by the Chinese government.
The investigation was started on November 25, 2024. Petitions were filed by Saint-Gobain Ceramics & Plastics, Inc., of Malvern, Pennsylvania. The USITC decided to move forward with the final phase after Commerce made a preliminary ruling that the imports were subsidized as stated in section 703(b) of the Tariff Act of 1930 (19 U.S.C. 1671b(b)).
A public notice was posted by the USITC about the final phase and a public hearing was scheduled. This information was made available in the Federal Register on June 2, 2025 (90 FR 23359). The hearing, which was planned for August 7, 2025, was later canceled, as announced in the Federal Register on August 8, 2025 (90 FR 38501).
The USITC’s findings were finalized and filed on September 19, 2025. The views of the Commission are published in USITC Publication 5669, dated September 2025. The document is titled “Sol Gel Alumina-Based Ceramic Abrasive Grains from China: Investigation Nos. 701-TA-750 and 731-TA-1728 (Final).”
Commissioner Johanson had a different view. He determined that the U.S. industry faces a threat of material injury from these imports, rather than current material injury.
These actions were completed according to sections 705(b) and 735(b) of the Tariff Act of 1930 (19 U.S.C. 1671d(b) and 1673d(b)).
The official order was issued by Sharon Bellamy, Supervisory Hearings and Information Officer of the USITC.
