### LC USA (미국 MEG 플랜트) (high)
- metric: volume 700,000 톤/년 · MEG 캐파
- note: The Lake Charles MEG plant (700kt/yr, world's largest at opening) takes ethylene from the adjacent LACC cracker — a vertically integrated downstream at the end of the U.S. low-cost feedstock chain (ethane→ethylene→MEG).

### 나프타 (GS칼텍스·HD현대오일뱅크 등) (high)
- note: The single feedstock holding half of costs — naphtha, the base input for the NCC, was KRW 5,015.1bn of purchases in FY2025, 50.8% of total. Sourced from GS Caltex, HD Hyundai Oilbank and others domestically; since the naphtha-ethylene spread is the margin, oil and FX swings drive results directly.
- [mentions] Newspim (KO, news, published 2026-05-11) https://www.newspim.com/news/view/20260511001115: "Naphtha procurement stable with continued supply scheduled."
- [confirms] FSS DART / Lotte Chemical (KO, filing, published 2026-03-12) https://dart.fss.or.kr/dsaf001/main.do?rcpNo=20260312001296: "Naphtha purchases KRW 5,015.1bn (50.8%), from GS Caltex, HD Hyundai Oilbank and others."

### Itochu (혼합자일렌 등 원료) (high)  → /itochu.md
- note: The aromatics feedstock axis — mixed xylene and related are sourced from Itochu and others, KRW 841.9bn in FY2025 (8.5% of purchases). The second-largest feedstock after naphtha, an upstream variable for aromatics (BTX, PIA) margins.

### 롯데에너지머티리얼즈 (high)  → /lotte-energy-materials.md
- note: The core bet to escape commodity chemicals — a consolidated subsidiary controlled via the 2023 Iljin Materials acquisition, entering the battery-materials chain with copper foil (Elecfoil). FY2025 battery-materials revenue was KRW 677.5bn (down from KRW 902.3bn on the EV air-pocket). The growth axis the company is shifting toward as commodity chemicals collapse, though the battery downturn is a near-term drag.

### LACC (웨스트레이크 50:50 JV) (high)
- note: The Lake Charles ethane-cracker JV in Louisiana (~1Mt ethylene/yr, 50:50 with Westlake) — feeding on cheap shale-based ethane for a cost edge over Asian naphtha, a key margin defense in the down-cycle; Westlake bought up to 50% in 2019/2022.
- [confirms] SEC EDGAR (EN, filing, published 2025-02-15) https://www.sec.gov/Archives/edgar/data/1262823/000126282325000011/wlk-20241231.htm: "Westlake acquired 34.8% of LACC for ~$817M (2019) and 3.2% for $89M (2022)."
- [confirms] Lotte Chemical USA (EN, ir, published 2024-06-01) https://lottechemusa.com/our-companies/lacc-llc/: "LACC 50/50 JV produces ~2bn lb of ethylene a year from ethane."
