What is the Trump administration's likely decision regarding the implementation timeline for the new polysilicon tariff and price floor?

The Trump administration is expected to reject industry requests for a shortened 90-day implementation timeline and instead maintain the originally planned 120-day delay before the new 15% tariff on polysilicon derivatives and associated price floor takes effect.

Why are some U.S. solar manufacturers urging a faster implementation of the polysilicon tariff?

Some U.S. solar manufacturers are lobbying for a 90-day implementation timeline—rather than the proposed 120 days—because they argue that the extra month would give China, a top producer of polysilicon products, too much time to increase exports to the United States, thereby harming domestic competitors.

The Trump administration is expected to reject U.S. solar manufacturers' requests to accelerate new polysilicon tariffs, maintaining a 120-day timeline over the requested 90 days. This aims to prevent Chinese producers from exploiting the transition period to flood the U.S. market.
