US to impose 15% tariff on polysilicon imports
US President Donald Trump on Thursday signed an executive order imposing minimum import prices and a 15% tariff on products made from polysilicon, a key material for solar panels and semiconductors.

The mechanism
The US order raises the landed cost of polysilicon-containing products through a 15% tariff and unspecified minimum import prices. EU solar-module manufacturers, semiconductor supply-chain firms and exporters selling such products into the US face weaker price competitiveness or margin compression; Chinese suppliers may redirect volumes toward other markets, including the EU, increasing competitive pressure on European producers.
The stakes
If the measure redirects Chinese polysilicon and downstream solar supply materially, Europe could face lower-priced imports while its manufacturers confront a more protected US market. It matters less if the order’s product scope is narrow, exemptions are extensive, or trade flows do not shift.
How it reaches Europe
- US tariff and price floors
- US import costs rise
- supplier trade flows adjust
- EU import competition changes
- EU exporters lose US margin
