Singapore. Supply chain mapped to 36 inputs across 11 countries.
Uncertain. Maxeon Solar Technologies 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), but its FEOC status is unresolved and depends on ownership or component-level analysis. Is Maxeon Solar Technologies a Foreign Entity of Concern?

Relationships
36 nodes, grouped by supply-chain tier. Sourcing risk describes where an input is mined or refined; it is not a FEOC determination for Maxeon Solar Technologies.
| Input | Origin | Sourcing risk | Basis |
|---|---|---|---|
| Maxeon Solar TechnologiesHQ Singapore; IBC cell fabs in Philippines & Malaysia; module assembly in Mexico & France | Singapore | Elevated sourcing risk | IBC/back-contact solar modules. Polysilicon explicitly non-China (Germany/Korea/US closed list), but downstream metals (Al frame, Cu, Ag, glass, encapsulant) run through China-dominated midstream -> overall review. |
| Input | Origin | Sourcing risk | Basis |
|---|---|---|---|
| IBC Solar Cell (crystalline silicon)Maxeon 3 cell fab, Philippines (~560MW); also Malaysia | Philippines | No known risk factor | Interdigitated back-contact cell built on a patented copper foundation; wafers made exclusively from non-China polysilicon. |
| Module Lamination & AssemblyMexicali/Mexico module plants; France | Mexico | Elevated sourcing risk | Cells laminated between glass/encapsulant, framed, and junction-boxed into finished panels. |
| Monocrystalline Silicon WaferThird-party ingot/wafer partners (TZS and others outside China) | Malaysia | Elevated sourcing risk | Maxeon does not ingot/wafer itself; specifies non-China polysilicon feedstock. Wafering partners partly in Asia -> review. |

| Copper Foundation / Plated Cu ContactsElectroplated onto rear of IBC cell | Philippines | Elevated sourcing risk | Maxeon's signature thick plated-copper metallization replaces silver ribbons. Copper metal midstream is China-heavy. |
| Silver Metallization PasteRear-contact paste (reduced vs standard cells due to Cu plating) | China | Covered nation | Silver paste for screen-printed contacts; paste conversion and silver refining concentrated in China. |
| Anodized Aluminum FrameExtruded/anodized Al profile | China | Covered nation | Rigid module frame; aluminum extrusion and smelting China-dominated. |
| Low-iron Tempered Solar GlassRolled 3.2mm patterned coverglass | China | Covered nation | China ~74% of solar-glass volume (Xinyi, Flat Glass Group, CSG) -> flagged. |
| EVA / POE Encapsulant FilmExtruded encapsulant film | China | Covered nation | Hangzhou First >50% share; encapsulant film supply China-dominated -> flagged. |

| Junction Box + Bypass DiodesRear-mounted J-box with diodes/connectors | China | Covered nation | J-box and connector supply concentrated in China -> flagged. |
| Tin-coated Copper Solder RibbonCopper ribbon with Sn(:Pb) solder coating | China | Covered nation | Interconnect ribbon; tin solder refining China-concentrated. |

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 Maxeon Solar Technologies, 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.
