    • 包装要求：陶瓷件必须使用泡沫垫+纸箱+托盘包装，要求供应商加”易碎品”标识。
    • 付款方式：新客户建议30%预付+70%提单副本支付；有合作历史后可谈T/T 45–60天或L/C。
    • 关税注意：氧化铝陶瓷通常归入HS Code 6903，欧美进口关税5–6.5%，请提前确认。

    总结：氧化铝陶瓷中国采购核心清单

    • ✅ 先确认Al₂O₃含量需求（75%/90%/95%/99%）
    • ✅ 要求样品测试密度、硬度、尺寸公差
    • ✅ 小批量试单验证质量稳定性后再下大单
    • ✅ 选择有ISO认证和出口经验的供应商
    • ✅ 批量订单务必做来料XRF检测
    • ✅ 海运+泡沫+托盘，防破损是重中之重

    本指南数据基于2026年第二季度市场信息，价格随行就市，仅供参考。实际采购请以供应商报价单和样品确认结果为准。

    ## Key Price Movements

    ### PTFE Resin: Sustained Downward Pressure

    PTFE suspended medium-grade price fell to ¥31,800/ton this week, marking a fresh low for the past 30 days, down ~3.6% from ¥33,000/ton last week and down a significant 33.8% from the monthly high of ¥48,000/ton.

    **Key Drivers:**
    – **Oversupply**: Rapid capacity expansion since 2024, concentrated in Shandong and Jiangsu provinces. Syensqo’s Changshu expansion project entered trial production in Q1, continuously releasing supply-side pressure
    – **Weak Demand**: Chemical and oil & gas sectors extending procurement cycles with spot purchasing only; no major restocking observed
    – **Easing Costs**: Fluorite stable at ¥3,250-3,350/ton (East China); crude oil retreat to $68-72/bbl reducing cost support
    – **Intensified Competition**: Domestic manufacturers locked in a price war; traders continue undercutting offers

    **Short-term Outlook:** No clear improvement in fundamentals expected in July. PTFE prices to remain in the ¥31,000-34,000/ton range with downside bias.

    —

    ### Carbon Fiber: Bottom Reversal Signal Solidifies, January Price Hikes Spill into Spot Market

    The carbon fiber market has reached a critical turning point. Toray announced a 10-20% price increase on TORAYCA brand carbon fiber and prepreg products effective January 2026; Jilin Chemical Fiber followed with ¥5,000/ton for wet 12TK and ¥10,000/ton for 3K carbon fiber.

    **Drivers:**
    – **Low-Altitude Economy Surge**: eVTOL, flying cars, and drone applications driving demand. Nearly 10 listed companies confirmed carbon fiber products are used in low-altitude scenarios via investor platforms
    – **Stable Wind Power Demand**: Blade lightweighting continues to boost large-tow carbon fiber procurement
    – **Cost Support**: Stabilization of crude oil and acrylonitrile raw material prices limiting further decline
    – **Capacity Cleanup Bearing Fruit**: 2024 domestic carbon fiber capacity growth slowed to 12.7%, a sharp moderation from 50%+ annual growth in 2021-2022

    **Short-term Outlook:** Domestic T300/24K carbon fiber expected to range ¥80-95/kg with a slight upside bias. Quality suppliers have exited the price war, pivoting to quality competition.

    —

    ### PEEK Resin: Domestic Substitution Accelerates, Price Range Stable

    Industrial-grade PEEK maintained ¥200-400/kg; imported VICTREX brands held at ¥800-1,500/kg.

    **Key Developments:**
    – Zhongyan Materials and Junhua Special Plastics continuing capacity expansion, accelerating domestic substitution
    – New energy EV motor insulation and semiconductor packaging driving high-end PEEK demand
    – DFBP (4,4′-difluorobenzophenone) raw material price stable, supporting flat pricing

    **Short-term Outlook:** Short-term stable; domestic material in the ¥200,000-400,000/ton range. Imported high-end products maintain elevated pricing due to concentrated supply.

    —

    ### PI Film: Localization Progresses, High-End Market in Shortage

    PI film market stable: domestic standard ¥180-255/m²; high-end electronic grade ¥600,000-3,000,000/ton; FPC coverlay ¥38-230/m².

    **Key Developments:**
    – Ruihua Tech’s semiconductor-grade PI film passed Korean semiconductor company evaluation, entering small-batch supply (June 17, 2026)
    – Asahi Kasei developed photosensitive PI film for advanced semiconductor packaging
    – 5G/AI driving rapid growth in thermal control PI film demand; AI equipment thermal management emerging as new growth engine

    **Short-term Outlook:** Standard PI film stable; high-end electronic/semiconductor-grade PI film likely to continue upward trend due to supply tightness.

    —

    ### Special Ceramic Raw Materials: Zirconium Oxychloride Rising

    – **Zirconium Oxychloride** (Zr+Hf≥36%): ¥18,750/ton, up ¥1,000/ton MoM (+5.6%), Shandong region
    – **Alumina**: Stable at ¥2,800-2,900/ton (port benchmark)
    – **Fluorite**: East China 97% wet powder ¥3,250-3,350/ton, weak trend

    **Driver:** Zirconium oxychloride uptrend driven by rare earth and new materials demand growth, coupled with environmental production restrictions in some regions tightening supply.

    —

    ## Impact Analysis

    ### Impact on Procurement Costs
    – **PTFE sharp decline**: Positive for seals, gaskets, and coating procurement. Estimated cost reduction of 3-5% for related products
    – **Carbon fiber bottom rebound**: eVTOL/drone component procurement costs rising ~1-2%; early-stage cost pressure emerging for low-altitude economy supply chain
    – **PI film stable**: FPC and electronic insulation material procurement costs controllable; no significant fluctuation

    ### Impact on Supply Chain
    – **PTFE oversupply continuing**: Enhanced buyer bargaining power; recommended to lock annual framework agreements at current low prices
    – **Carbon fiber supply structure improving**: Post-2023-2024 capacity consolidation, supply concentration increasing; quality supplier scarcity highlighted
    – **PI film localization**: Domestic suppliers like Ruihua Tech providing stable supply, reducing import dependency risk

    —

    ## Action Recommendations

    ### Materials to Lock In Prices (Recommended)

    **1. Carbon Fiber** ⭐⭐⭐ (Highly Recommended)
    – Reason: Upward price trend confirmed (Toray +10-20%, Jilin CF +¥5,000-10,000/ton); low-altitude economy demand surge will sustain upward momentum
    – Action: Secure Q3-Q4 supply agreements with Jilin Chemical Fiber, Zhongfu Shen鹰 (AVIC Composite), and other domestic suppliers immediately

    **2. PTFE** ⭐⭐ (Moderately Recommended)
    – Reason: Current ¥31,800/ton near annual low with limited downside; oversupply limits upside
    – Action: Lock 3-6 month supply contracts at current low prices; prioritize domestic suspension medium-grade specifications

    ### Materials to Monitor

    1. **PEEK Resin**: Significant gap between domestic and imported pricing (10x); procurement strategy depends on specific application performance requirements
    2. **PI Film**: Standard grades stable; consider restocking high-end electronic grade on price pullbacks

    ### Key Events to Watch
    – **Mid-July**: Zhangyuan Tungsten long-term purchase price (significant cut this week; watch for tungsten-based ceramic raw material linkage effects)
    – **Late July**: Carbon fiber manufacturers’ monthly price adjustment window; low-altitude economy order release progress
    – **EIA Monthly Report**: EIA’s revised 2026 WTI average forecast down to $76.26/bbl (down $12); monitor downstream impact on petrochemical material costs
