Back to supply chains
Where does Chint Power Systems source its components?
China. Supply chain mapped to 34 inputs across 5 countries.
Federal screeningFlagged
Yes. Chint Power Systems 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 Chint Power Systems a Foreign Entity of Concern?

Every mapped input in the Chint Power Systems supply chain
34 nodes, grouped by supply-chain tier. Sourcing risk describes where an input is mined or refined; it is not a FEOC determination for Chint Power Systems.
Producer (1)
| Input | Origin | Sourcing risk | Basis |
|---|---|---|---|
| Chint Power SystemsShanghai, China (HQ / productization); Chint Group manufacturing, China | China | Covered nation | China-headquartered PV inverter maker (part of Chint Group, Shanghai). US arm CPS America runs R&D in Dallas, TX but core production and supply chain sit in China; China HQ = FEOC-flagged. |
Component (14)
| Input | Origin | Sourcing risk | Basis |
|---|---|---|---|
| Power Semiconductor Module (IGBT / SiC) | China | Covered nation | DC-AC switching stage. IGBT modules and increasingly SiC MOSFET modules; Chinese IDMs (e.g. CR Micro, Yangjie, StarPower) dominate domestic module packaging. |

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 Chint Power Systems, 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 Chint Power Systems source the inputs in this product?
- This map traces 34 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 Chint Power Systems supply chain sits in a covered nation?
- 30 of 34 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 2 carry elevated sourcing risk without either basis.
- Is Chint Power Systems itself a Foreign Entity of Concern?
- Yes. Chint Power Systems 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.
