Trump Administration Expected to Deny Faster Polysilicon Tariff Implementation, Source Says

The Trump administration is expected to reject requests from some U.S. solar manufacturers to speed up the implementation of a new price floor and tariff on imported polysilicon products, a person familiar with the matter said on Tuesday.

This decision would maintain the originally planned timeline, providing a longer window before the new trade restrictions take effect on the key raw material used in solar panels.

Proposed Trade Measures

The new measures, which a Reuters report indicated could be unveiled as soon as Thursday, include a 15% tariff and a price floor for polysilicon derivatives. According to four sources cited in the report, these restrictions were initially scheduled to take effect 120 days following the official announcement.

This four-month period is designed to give the market time to adjust. However, it has become a point of contention for some domestic producers.

Industry Pushback and Concerns

Ad

Some U.S. solar industry players have been actively lobbying the administration for a shorter, 90-day implementation timeline. Their primary concern is that a 120-day window would give foreign competitors, particularly from China, too much time to increase shipments to the United States before the tariffs are enacted.

Proponents of the faster timeline argue that such a surge in imports could undermine the intended protective effect of the tariffs and harm U.S. rivals by flooding the market. The administration's apparent decision to stick with the original schedule suggests these arguments were not persuasive.

Market Impact

Maintaining the 120-day implementation period means that importers and manufacturers reliant on polysilicon will have a four-month runway to manage their supply chains and pricing strategies before the new cost structure is imposed. While this provides more adjustment time, it also prolongs the period of market uncertainty and could lead to significant inventory stockpiling ahead of the deadline.
