Canonical: https://valuechain.wiki/xiaomi · Facet: suppliers · Updated: 2026-07-12T05:39:59.787128+00:00 · Source: ValueChain.wiki (cited money-flow graph)

**Citable summary**: Xiaomi's confirmed suppliers/cost counterparties include Sunny Optical, BYD Electronics, CATL plus 4 undisclosed/aggregate relationships. Per the valuechain.wiki graph: 7 cost edges, backed by 9 dated sources, 1 of them primary filings (as of 2026-07-12).

### 써니옵티컬 (high)  → /sunny-optical.md
- note: Sources smartphone camera lenses and modules from Sunny Optical (global No.1 in both) — with the camera a key differentiator in premium phones, securing high-end optics ties directly to the competitiveness of Xiaomi's flagships.
- [confirms] South China Morning Post (EN, news, published 2025-08-01) https://www.scmp.com/topics/sunny-optical: "Xiaomi sources smartphone camera lenses/modules from Sunny Optical (the world's largest lens maker), which supplies major brands including Apple, Samsung, Huawei and Xiaomi."

### BYD일렉트로닉스 (high)  → /byd-electronics.md
- note: Outsources part of smartphone assembly and components to BYD Electronics (China's No.2 EMS after Foxconn) — one leg of assembly-partner diversification in a fabless-manufacturing model.
- [confirms] ZDNet Korea (KO, news, published 2020-09-16) https://zdnet.co.kr/view/?no=20200916075312: "See counterpart edge source."

### CATL (high)  → /catl.md
- note: Supplies ternary (NMC) batteries for SU7 upper trims and YU7 Max, the high-performance tier — Xiaomi dual-sources from CATL and BYD to spread dependence, price and volume risk. As the battery is the largest EV cost item, this dual-sourcing is central to margin and supply stability.
- [confirms] CarNewsChina (EN, news, published 2025-06-30) https://carnewschina.com/2025/06/30/xiaomis-hit-yu7-suv-launch-omits-any-mention-of-battery-supplier-catl/: "YU7 dual-motor uses CATL ternary cells."

### BYD (핀드림스 배터리) (high)  → /byd.md
- note: Supplies LFP batteries (BYD's FinDreams) for SU7 Standard and single-motor YU7 — the value/entry tier, dual-sourced against CATL's ternary cells. Splitting battery suppliers by trim optimizes cost, safety and supply.
- [confirms] CnEVPost (EN, news, published 2024-05-27) https://cnevpost.com/2024/05/27/xiaomi-su7-standard-gets-random-catl-byd-batteries/: "SU7 Standard randomly fitted with FinDreams or CATL cells."

### Qualcomm (high)  → /qualcomm.md
- note: Primary flagship AP source (Snapdragon) — but Xiaomi runs its in-house 3nm XRING alongside it to reduce sole dependence on Qualcomm. As the AP drives smartphone cost and performance, scaling its own silicon is what will shape long-term procurement leverage and differentiation.
- [mentions] CNBC (EN, news, published 2025-05-19) https://www.cnbc.com/2025/05/19/chinas-xiaomi-commits-6point9-billion-to-in-house-chips.html: "$6.9B chip push alongside continued Qualcomm sourcing."

### TSMC (XRING 파운드리) (high)  → /tsmc.md
- note: Fabs its XRING O1 — the first Chinese-designed 3nm flagship SoC — at TSMC N3E; as the RMB50bn chip-R&D commitment signals, Xiaomi internalizes design but still depends on TSMC for leading-edge fabrication. The in-house chip is a long-term bet on easing Qualcomm dependence and differentiating hardware, with 1M+ units shipped proving viability.
- [confirms] Xiaomi Corporation (EN, filing, published 2026-04-28) https://www1.hkexnews.hk/listedco/listconews/sehk/2026/0428/2026042800526.pdf: "In-house 3nm XRING chip program with committed multi-year R&D (~RMB50bn); fabbed at external foundry."
- [confirms] Xiaomi IR (EN, ir, published 2026-03-24) https://ir.mi.com/system/files-encrypted/nasdaq_kms/assets/2026/03/24/6-20-53/Xiaomi%20Corp_25Q4_ER_ENG%20vF.pdf: "FY2025 revenue RMB 457.3bn; EV/AI RMB 106.1bn; 411k EVs."
- [confirms] DigiTimes (EN, news, published 2025-05-22) https://www.digitimes.com/news/a20250522PD208/xiaomi-xring-soc-tsmc-3nm-production.html: "XRING O1 on TSMC N3E; first Chinese-designed 3nm flagship SoC."

### 샤오미 생태계·공급망 투자 포트폴리오(약 410개사) (high)
- note: The ~RMB89.0bn portfolio (RMB87.1bn book) across ~410 companies is strategic, not merely financial — locking in the IoT ecosystem, components and EV supply chain. Individual stakes are mostly <5%, but tying ecosystem firms with capital broadens the supply and content base of the hardware flywheel (RMB3.1bn after-tax disposal gain in 2025).
- [confirms] Xiaomi Corporation (EN, filing, published 2026-04-28) https://www1.hkexnews.hk/listedco/listconews/sehk/2026/0428/2026042800526.pdf: "Invested in ~410 companies, book value RMB87.1bn, total RMB89.0bn (Dec 31, 2025)."

### 웨이얼반도체(윌세미) (mid)  → /will-semiconductor.md
- note: Sources high-resolution CMOS image sensors (OV50 family) from Will Semiconductor (OmniVision) for phone cameras — with the camera a key premium differentiator, securing high-pixel sensors ties directly to flagship competitiveness. It runs a multi-sensor supply base to spread single-supplier dependence.
- [confirms] Korea Economic Daily (KO, news, published 2025-07-13) https://www.hankyung.com/article/2025071352391: "OmniVision's OV50H and similar cost-effective sensors are widely adopted by Chinese smartphone makers."
