On Wednesday, August 5, 2026, the Trump administration announced plans to impose a 15% tariff on polysilicon derivative products. This move follows the conclusion of a Section 232 investigation into foreign imports of polysilicon. According to sources cited by Reuters, the administration intends to unveil the investigation results as soon as Thursday, August 6, 2026. Polysilicon is a key material used in the manufacturing of solar panels and semiconductors.

The announcement was reported by CNA Latest News, which attributes the information to unnamed sources familiar with the matter. The tariff is expected to impact the Asia-Pacific region, a significant supplier of polysilicon products.
