Understanding the pricing structure is the first step to avoiding procurement traps.

6 Key Factors Driving Carbon Fiber Prices
Precursor Quality
- Details: PAN (polyacrylonitrile) precursor quality directly determines CF performance; precursor cost accounts for 50%+ of total CF cost
Carbonization Process - Details: High-temperature carbonization equipment energy consumption and process precision vary significantly
Production Scale - Details: Economy of scale — a 10,000-ton facility vs. 1,000-ton plant can see cost differentials of 30–50%
Brand Premium - Details: International brands (Toray, Hexcel, SGL) command premium pricing; domestic brands offer better value
Tow Size - Details: Small tow (1K/3K) commands higher prices than large tow (12K+) due to process complexity
Market Supply & Demand - Details: Global CF supply has been relatively tight in recent years; new capacity coming online in 2024+ is easing the market

2024–2025 Market Price Reference (USD/kg)
T300 Carbon Fiber Fabric - Price Range: $8–16 /kg
T700 Carbon Fiber Fabric - Price Range: $14–28 /kg
T700 UD Prepreg - Price Range: $25–48 /kg
CFRP Hot-Press Sheets - Price Range: $20–55 /kg
Custom CFRP Machined Parts - Price Range: Quote required
⚠️ Watch out for suspiciously low prices. Products sold as “T700” that are actually T300, or “domestic origin” with unclear sourcing, are common in the market. Suppliers offering more than 30% below market rates require rigorous verification of test reports and chain-of-custody documentation.

The 5-Dimensional Supplier Evaluation Method
Don’t select suppliers on price alone. Assess across five dimensions:
Product Quality - What to Evaluate: Test reports (tensile strength/modulus/density), batch consistency, third-party certifications
- Weight: ★★★★★
Technical Support - What to Evaluate: Can they provide layup design, process consulting, and material selection guidance?
- Weight: ★★★★☆
Delivery Capability - What to Evaluate: Stock availability, lead times, emergency order response
- Weight: ★★★★☆
Price Reasonableness - What to Evaluate: Quote transparency, inclusion of tax/freight, MOQ reasonableness
- Weight: ★★★☆☆
After-Sales Service - What to Evaluate: Quality dispute resolution, return/exchange policy, technical training
- Weight: ★★★☆☆

Pre-Procurement Checklist
✅ Request samples (1–3 kg) for your own testing before bulk orders
✅ Demand batch test certificates from CMA/CNAS accredited labs with every shipment
✅ Specify in contracts: grade (e.g., T700), tow size (e.g., 3K), fabric spec (grammage, thickness), and surface treatment
✅ Start with a small trial order for new suppliers to verify quality consistency and delivery reliability
