    Supply Chain Impact

    • High-end carbon fiber (T800+) supply-demand imbalance unlikely to resolve short-term — recommend locking in long-term supply contracts
    • PEEK domestic substitution is accelerating with new capacity coming online, helping shorten lead times and reduce costs
    • Guinea bauxite policy uncertainty adds risk to the alumina supply chain — monitor closely

    Actionable Recommendations

    Lock-in Pricing

    • Carbon Fiber T700/T800 — Acrylonitrile cost support + high-end tight balance; upward trend confirmed. Recommend quarterly fixed-price contracts.
    • PI Film (Electronic Grade) — Battery/FPC demand growth driving moderate price increases. Recommend advance stockpiling.

    Hold and Watch

    • PTFE Resin — Capacity expansion + soft demand; further downside possible. Purchase on-demand, avoid bulk price-locking.
    • Alumina — Futures driven by news but spot stable with high inventories. Wait for Guinea policy clarity before committing.
