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 ZTT Group (Zhongtian Technology), 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 ZTT Group (Zhongtian Technology) source the inputs in this product?
- This map traces 46 inputs across 7 countries, including 16 mines and refiners. It is compiled from public sources and is not an audited bill of materials.
- How much of the ZTT Group (Zhongtian Technology) supply chain sits in a covered nation?
- 35 of 46 mapped inputs are sited in a covered nation (China, Russia, Iran or North Korea) or named on a federal restricted-party list. A further 7 carry elevated sourcing risk without either basis.
- Is ZTT Group (Zhongtian Technology) itself a Foreign Entity of Concern?
- Yes. ZTT Group (Zhongtian Technology) 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.
