Certain TOPCon Solar Cells, Modules, Panels, Components Thereof, and Products Containing Same; Notice of a Commission Determination Not To Review an Initial Determination Granting the Parties' Joint Motion To Terminate the Investigation; Terminating Investigation

Brief takeaway: A Section 337 investigation at the ITC involving certain TOPCon solar cells and related products has been ended entirely, so the associated exclusion proceeding is no longer active.

What changed: According to the notice, the Commission determined not to review an initial determination (Order No. 40) that granted the parties' joint motion to terminate the investigation. The notice states the investigation is terminated in its entirety.

Who's affected: The notice names certain TOPCon solar cells, modules, panels, components thereof, and products containing the same. It does not specify HTS codes or countries of origin. Importers of these solar products may find the termination relevant to any concerns about a related ITC exclusion action.

What to review:
- Review whether your products fall within the "TOPCon solar cells, modules, panels, components" descriptions referenced in the notice.
- Confirm with your broker or trade counsel whether any prior exclusion order, cease-and-desist order, or entry restrictions tied to this investigation were ever in place and their current status.
- Check whether other pending ITC, AD/CVD, or Section 201/301 actions on solar products may still affect your imports, since this notice addresses only this investigation.
