Tesla and SpaceX are reportedly exploring a broad group of South Korean suppliers for Terafab, covering chipmaking equipment, process materials, testing components and factory systems. The outreach suggests supply-chain planning is underway, but it does not amount to a confirmed production-vendor roster: the clearest reported equipment commitment is one HPSP system for a research line. 1

What the supplier outreach shows
Representatives associated with Terafab visited about 10 South Korean company booths at SEMICON West in San Francisco on October 13, 2026. More than half of the suppliers reportedly signed nondisclosure agreements, while discussions ranged from introductory inquiries to product-specific conversations and technical exchanges. 7

The reported contacts span several parts of a chipmaking operation:
- Equipment: HPSP agreed to supply one high-pressure hydrogen annealing system for Terafab’s research line. Hanmi Semiconductor was reportedly discussing thermocompression, or TC, bonders.

27
- Testing and cleaning: ISC was exchanging samples and design information for semiconductor test sockets. KoMiCo, MiCo’s cleaning subsidiary, reportedly signed a three-party NDA with Tesla and SpaceX concerning cleaning services for a Texas R&D pilot line.

- Environmental and facility systems: Unisem reportedly signed an NDA for discussions that included waste-gas scrubbers. BMT discussed valves and fluid-handling components, while Asflow was approached about piping components and valves.
- Process materials and wastewater: Dongjin Semichem had reportedly been discussing potential materials supply with Tesla for two to three months, including possible supply from its Texas thinner plant. ENF Technology was asked about process materials, and G&G Intech received inquiries about wastewater-recycling equipment.
These contacts are at different stages. An NDA permits confidential discussions; it does not establish that a supplier has won a contract. The reported sample and design exchanges suggest technical evaluation in some cases, while other conversations were still introductory. 10

HPSP’s commitment is for research, not production
The key distinction is between the reported R&D-line commitment and equipment orders for the eventual production plant. HPSP’s agreement covers one high-pressure hydrogen annealing system for Terafab’s research line. TokenPost described it as the only specifically identified equipment commitment in its account of the supplier discussions. The reporting does not establish that HPSP—or any of the other companies listed—has received a production-plant order. 1
Hanmi’s reported discussions about TC bonders should be treated similarly: they indicate a possible supplier conversation, not a confirmed production award. 27
Many contacts may build on existing relationships
The outreach reportedly included companies that already did business with Tesla or SpaceX, rather than only new prospective vendors. BMT, for example, was reported to supply piping components to SpaceX. Existing commercial ties may provide a starting point for discussions, but they do not confirm Terafab-specific contracts. 10

HPSP and Hanmi were the Korean suppliers previously linked publicly to the project. The newer reporting widens the list of companies in discussions, but the available material does not establish an official supplier list or a complete allocation of production contracts. 10
What this means for Terafab—and what remains unknown
Terafab’s reported first-phase investment is more than $16.8 billion, with at least 3,000 jobs planned. That scale helps explain why the project would need suppliers across many categories, but it does not show that procurement is complete. 38
The supplier reports also do not independently verify several larger project details, including specific wafer-output targets, the project’s ownership and legal structure, or the timing and terms of any production-scale supplier awards. Those points should remain separate from the reported NDAs and early-stage discussions.
On October 20, Elon Musk said the value of Terafab’s output would place it “in the top 20 of country GDP in a single building.” That is a forward-looking claim, not a demonstrated output figure or an independently validated economic forecast. 2
