Imports of Si‑C Anode Products Could Be Blocked
The complainants have asked the Commission to issue a limited exclusion order and cease and desist orders after the investigation. The investigation, instituted on July 21, 2026, covers imports, sale for importation, and sale within the United States of certain composites comprising silicon carbon material for battery anodes ("Si‑C Anode Products"), which could stop those accused products from being brought into or sold in the U.S.

Those respondents must submit responses in accordance with 19 CFR 210.13, and responses will be considered if received not later than 20 days after service; failure to respond may lead to a waiver and possible issuance of exclusion or cease and desist orders.
