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 Shanghai Electric Wind Power, 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 Shanghai Electric Wind Power source the inputs in this product?
- This map traces 37 inputs across 4 countries, including 9 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
- How much of the Shanghai Electric Wind Power supply chain sits in a covered nation?
- 32 of 37 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 Shanghai Electric Wind Power itself a Foreign Entity of Concern?
- Yes. Shanghai Electric Wind Power is covered by a federal restricted-party designation on the DOD Section 1260H list, through the related entity named in the citation below. Sourcing risk in this map describes where inputs are mined and refined and is a separate question from the company's own federal screening.
