📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: The ITC has begun a Section 337 patent investigation into certain imported foundry coke, which could lead to import restrictions if a violation is found.

What changed: According to the notice, the ITC instituted an investigation on June 15, 2026 (supplemented July 1, 2026) based on a complaint by SunCoke Technology and Development LLC and Jewell Coke Company L.P. The notice states the complaint alleges Section 337 violations tied to importation, sale for importation, and post-importation sale of certain foundry coke that allegedly infringes claims of U.S. Patent Nos. 12,600,915 and 12,331,367. The notice indicates the complainants request a limited exclusion order and cease and desist orders.

Who's affected: The notice names the product as certain foundry coke. No HTS chapters, codes, or countries of origin are specified in the notice.

What to review:
- Review whether your imported products fall within the "certain foundry coke" described in the complaint.
- Confirm with your broker or trade counsel whether the '915 or '367 patents may be relevant to your goods.
- Check whether you are named as a respondent or should monitor the docket as the investigation proceeds.
- Confirm the status and scope of any limited exclusion order or cease and desist orders if issued.
