Where does Nordex SE source its components?
Germany. Supply chain mapped to 35 inputs across 10 countries.
Federal screeningClean
No federal designation found. Nordex SE 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), and Germany is not a covered nation under the FEOC rules. Is Nordex SE a Foreign Entity of Concern?

Every mapped input in the Nordex SE supply chain
35 nodes, grouped by supply-chain tier. Sourcing risk describes where an input is mined or refined; it is not a FEOC determination for Nordex SE.

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 Nordex SE, 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 Nordex SE source the inputs in this product?
- This map traces 35 inputs across 10 countries, including 13 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
- How much of the Nordex SE supply chain sits in a covered nation?
- 10 of 35 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 15 carry elevated sourcing risk without either basis.
- Is Nordex SE itself a Foreign Entity of Concern?
- No federal designation found. Nordex SE 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), and Germany is not a covered nation under the FEOC rules. Sourcing risk in this map describes where inputs are mined and refined and is a separate question from the company's own federal screening.
