**Impact Analysis**

– **On Procurement Costs:** The 20% PI film price hike will directly inflate costs for FPC (flexible printed circuits) and electronic insulation material buyers, translating to ~8–12% cost increase in finished goods. Carbon fiber cost pressure is being passed through to wind blade and aerospace structural component manufacturers. The PTFE dip offers a temporary reprieve—consider spot restocking at lower price levels.

– **On Supply Chain:** PI film imports face logistics uncertainty due to Hormuz Strait risks; early securing of supplier quotas is recommended. Carbon fiber (T800+) domestic capacity expansion remains limited; sustained demand from wind energy and low-altitude mobility keeps the market in under-supply. PEEK supply chain is relatively stable, though high-end imported grades carry FX exposure.

—

**Action Recommendations**

– **Lock in Immediately:** PI Film — Kaneka’s 20% hike is already effective. Confirm Q2 supplier allocations now to avoid further price追逐 (chasing).
– **Lock in:** Carbon Fiber (T800 and above) — tight supply + cost support makes short-term price hikes likely. Lock in 3–6 months of volume.
– **Opportunistic Buying:** PTFE — prices are gently correcting with adequate spot supply. Monitor for a better window before full restocking.
– **Procure as Needed:** PEEK (domestic grades) — stable and well-supplied; match purchases to production schedule. For premium imported grades, time purchases around favorable FX.
– **Procure as Needed:** Specialty Ceramic Raw Materials — market is flat; purchase high-purity feedstocks per project demand.

Key Changes

• Carbon Fiber Precursor: +41% — On April 9, precursor prices surged 41% in a single day, breaking through 37,000 CNY/ton. Hengshen Co. led the price increase at 5,000-10,000 CNY/ton, followed by Jilin-series, Shanghai-series, and Toray. This rally is driven by rising acrylonitrile costs and a fundamental supply-demand reversal. Q1 2026 average carbon fiber price rose 3.07% YoY, ending a three-year downtrend.
• PTFE Suspension Medium Grain: Flat — Oilchem reported 47,000-54,000 CNY/ton on April 17. Luxi Chemical recently cut 1,000 CNY/ton to 34,000 CNY/ton, but the overall market remains stable with no major supply disruptions.
• PEEK Industrial Grade: Slight Decline — Domestic PEEK prices have fallen from a peak of 800,000-1,200,000 CNY/ton to 300,000-500,000 CNY/ton. Localization rate increased from 18% (2020) to 42%, with a 2026 policy target of 60%. Accelerating substitution continues to push industrial-grade prices down, while medical-grade remains firm at 800,000-1,000,000 CNY/ton.
• Alumina Futures: -2.6% — AO2605 closed at 2,673 CNY/ton with a weekly drop of 2.6%. Capacity release and loose inventory are the main drivers, with cautious market sentiment prevailing.

Impact Analysis

Procurement Cost Impact

• Carbon fiber precursor surge will transmit to finished products, raising cost pressure for wind turbine blades and hydrogen storage tanks. T800+ high-end grades remain in tight supply with greater price elasticity.
• PEEK domestic substitution dividend continues; industrial-grade procurement costs expected to decline further, benefiting semiconductor and automotive component manufacturers.
• Weakening alumina reduces cost support for specialty ceramic raw materials, but powder processing has lagged price transmission — limited short-term impact.

Supply Chain Impact

• Carbon fiber price hikes may trigger advance order locking by downstream customers. Short-term demand pulse combined with insufficient supply elasticity could push Q2 price center further upward.
• PI film electronic-grade demand remains stable (FPC, battery separators). Domestic Kapton alternatives are scaling up, reducing import dependency.

Actionable Recommendations

Lock-in Prices

• Carbon Fiber: Precursor surge is a clear signal; finished product price increases are highly likely. Recommend securing Q2 T700-and-below general-grade order volumes in advance.
• PTFE Suspension Medium Grain: Currently stable, but fluorine chemical supply chain faces environmental production curbs. H2 supply contraction risk warrants moderate inventory building.

Wait and Watch

• PEEK Industrial Grade: Domestic substitution accelerating; further price decline expected. Avoid large-volume lock-in; adopt small-batch, high-frequency procurement strategy.
• Alumina: Futures continuing to weaken; supply-loose pattern unchanged. Wait for lower price levels before large-order procurement.
• PI Film: Prices stable; domestic alternatives emerging. Recommend monitoring domestic Kapton film mass-production progress before making procurement decisions.
