ITC Section 337 case: glass LCD substrates found in violation
The U.S. International Trade Commission has determined to review in part an administrative law judge's finding that certain glass substrates for liquid crystal displays (LCDs), products containing them, and manufacturing methods violate Section 337 of the Tariff Act of 1930. The Commission is now requesting written submissions from parties and interested persons on remedy, public interest, and bonding issues. This case affects importers and manufacturers of LCD glass substrate products.

On June 11, 2026, the U.S. International Trade Commission published notice of its determination to review in part a final initial determination (FID) from the presiding administrative law judge, which found a violation of Section 337 of the Tariff Act of 1930. The violation involves certain glass substrate for liquid crystal displays (LCDs), products containing the same, and methods for manufacturing.
What's Affected
This Section 337 investigation concerns glass substrates used in LCD manufacturing and downstream products containing these substrates. The ALJ's FID determined that infringing products and processes violated Section 337, which prohibits unfair acts and methods of competition in the importation and sale of articles into the United States.
The Commission's partial review of the ALJ's decision means that while the violation finding stands, certain aspects of the determination are subject to further Commission examination. The agency is now soliciting written submissions from all interested parties—including the respondents, complainants, interested government agencies, and the general public—on three critical issues:
- Remedy: What relief should be imposed, which may include import exclusion orders or cease-and-desist orders
- Public Interest: Whether public interest considerations warrant modifying or limiting any relief
- Bonding: What bond amount, if any, should be required during the appeal period
"The Commission requests written submissions from the parties, interested government agencies, and other interested persons on the issues of remedy, the public interest, and bonding, under the schedule set forth below," according to the Federal Register notice.
Impact on LCD Substrate Importers
Importers and manufacturers of glass LCD substrates must monitor this proceeding closely. Section 337 relief—particularly import exclusion orders—can effectively block entry of infringing goods. The outcome will determine whether certain glass substrates and LCD products containing them face import restrictions, and the remedy phase will establish the scope and strength of any enforcement action.
What this means for shippers
Importers of glass LCD substrates and finished products using these substrates must follow this ITC proceeding to the final determination. An adverse ruling could result in import exclusion orders that prevent shipments from entering the U.S. market entirely. Review the complete Federal Register notice for submission deadlines and detailed procedural requirements, then consult with your trade counsel to assess your product's vulnerability and determine whether to file comments on remedy or bonding. Failure to anticipate an exclusion order risks significant supply-chain disruption and inventory write-downs.
