Tesla suppliers list and supply chain
A selected, source-linked Tesla suppliers list covering company-level battery and semiconductor relationships plus historical Model S brake records. The table distinguishes disclosures, agreements and model-specific service evidence instead of treating them as a complete map of every Tesla vehicle.
Tesla suppliers list and supply chain
Sources reviewed:
A selected list of company-level disclosures and historical model evidence. The source and coverage for each relationship are shown below. A named customer, an announced manufacturing agreement and a service-manual component are different kinds of evidence.
| Company / component | Documented relationship | Model / coverage | Evidence status | Sources |
|---|---|---|---|---|
| Panasonic | Lithium-ion battery cells | Tesla vehicles and energy storage; no model allocation made here | Company-level disclosure | [1] |
| CATL | Lithium-ion battery cells | Tesla vehicles and energy storage; no model allocation made here | Company-level disclosure | [1] |
| Samsung Electronics | Semiconductor contract-manufacturing agreement | Tesla, Inc.; no chip, process node, vehicle model or plant identified in this source | Agreement disclosure | [2] |
| STMicroelectronics | Tesla named among major customers | Company-level customer relationship; no specific chip or vehicle assignment | Customer disclosure | [3] |
| Brembo | Rear left brake-caliper service procedure | 2012–2020 Model S manual; applicability depends on configuration | Historical model evidence | [4] |
| Mando | Rear integrated parking-brake calipers | Model S base vehicles built after 2016-11-16, within the 2012–2020 manual | Historical model evidence | [4] |
Limitations
- Company-level disclosures do not establish supplier allocations for every Tesla model, battery chemistry, production site or model year.
- Samsung’s disclosed agreement does not specify a vehicle, chip, process node or fabrication plant. Those details are not inferred here.
- The Model S brake procedures describe historical configurations, not the brakes on every current Tesla.
- The 2025 smelter/refiner list concerns potentially upstream facilities. Tesla explicitly does not confirm that a listed facility was active in its chain; those facilities are excluded from this confirmed-relationship selection.
- The source-linked list does not verify the additional legacy map entries. Product-level maps retain their own records and are not populated from these company-level disclosures.

TeslaFrequently Asked Questions
Who are Tesla’s suppliers?
Tesla’s 2025 annual report names Panasonic and CATL for battery cells. Samsung discloses a semiconductor foundry agreement, and STMicroelectronics names Tesla among major customers. Brembo and Mando entries here are limited to historical Model S service evidence.
Is this a complete Tesla suppliers list?
No. This is a selection of documented relationships, not a complete supplier census, current procurement list or measure of market share. The interactive map contains additional records that this source list does not verify.
Do these suppliers provide the same parts for every Tesla model?
That is not established by these sources. Company-level cell or semiconductor disclosures do not identify every model, configuration or factory. The brake evidence is restricted to the stated 2012–2020 Model S manual and configuration limits.
Are companies on Tesla’s smelter list direct suppliers?
Tesla says it does not deal directly with the 3TG smelters/refiners in that list and cannot confirm that any listed facility was active in its supply chain. The list is not proof of a direct supplier relationship or a component in a particular model.
