Where does SPI Energy source the inputs in this product?

This map traces 36 inputs across 5 countries, including 10 mines and refiners. It is compiled from public sources and is not an audited bill of materials.

How much of the SPI Energy supply chain sits in a covered nation?

31 of 36 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 3 carry elevated sourcing risk without either basis.

Where does SPI Energy source its components?

China. Supply chain mapped to 36 inputs across 5 countries.

Federal screeningFlagged

Yes. SPI Energy (Xinyi Solar subsidiary interest) is organized in China, a covered nation under the FEOC rules, which makes it a foreign entity of concern for IRA clean-energy tax credit purposes. It is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List). Is SPI Energy a Foreign Entity of Concern?

Sources and methodology

Research-based supply-chain map compiled from public sources - not an audited bill of materials. Tiers reflect the standard industry structure for this product. Sourcing risk on a node describes where that input is typically mined or refined; it is not a FEOC determination for SPI Energy, and it is not a screening result for the node itself unless a federal listing is cited against it. Verify against primary documentation before making a compliance determination.

Common questions

Where does SPI Energy source the inputs in this product?: This map traces 36 inputs across 5 countries, including 10 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
How much of the SPI Energy supply chain sits in a covered nation?: 31 of 36 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 3 carry elevated sourcing risk without either basis.
Is SPI Energy itself a Foreign Entity of Concern?: Yes. SPI Energy (Xinyi Solar subsidiary interest) is organized in China, a covered nation under the FEOC rules, which makes it a foreign entity of concern for IRA clean-energy tax credit purposes. It is not named on any of the 3 federal restricted-party lists screened for this record (DOD Section 1260H, BIS Entity List, OFAC SDN List). Sourcing risk in this map describes where inputs are mined and refined and is a separate question from the company's own federal screening.
