Polyacrylonitrile fiber price

When sourcing PAN fiber, the price is heavily influenced by denier (fineness), cut length, and tensile strength. For textile applications, look for a tenacity of 3.0-5.0 g/d, while technical grades for carbon fiber precursors require much higher purity and strength. Ensure the moisture regain is approximately 1.0-2.0% to maintain consistent weight and processing quality. Prices will fluctuate based on whether the fiber is bright, semi-dull, or dull, as well as the acrylonitrile (AN) content percentage.

The end-use significantly dictates the price tier. Textile-grade PAN (Acrylic), used for sweaters and blankets, is generally the most cost-effective due to high-volume production. Technical-grade PAN, used as a concrete reinforcement additive to prevent cracking, carries a premium due to specific surface treatments. The most expensive is Specialty-grade PAN (Precursor) for carbon fiber manufacturing, which requires ultra-high purity and specific molecular weight distribution to ensure carbonization stability.

To ensure product safety and performance, verify that the supplier adheres to ISO 9001 for quality management and ISO 14001 for environmental standards. For construction applications, check for compliance with ASTM C1116 (Standard Specification for Fiber-Reinforced Concrete). If the fiber is used in apparel, OEKO-TEX® Standard 100 certification is essential to guarantee the absence of harmful substances. Always request a Certificate of Analysis (COA) for every batch to confirm chemical composition.

Buyers should leverage economies of scale by targeting orders of at least 5-10 metric tons to reduce the per-kilogram price. Since PAN fiber is a petroleum-based product, prices are sensitive to crude oil and acrylonitrile monomer market trends; consider long-term fixed-price contracts to hedge against price volatility. Additionally, sourcing from integrated manufacturers on Made-in-China.com who produce their own precursors can reduce middleman markups by 10-15%.

The main risks include quality inconsistency between samples and bulk shipments and fluctuations in international freight costs. To mitigate these, use third-party inspection services (like SGS or Intertek) before the final payment. Ensure the transaction is protected by Trade Terms that clearly define the point of risk transfer, and prioritize suppliers with a high Diamond Member status on Made-in-China.com to ensure business legitimacy.

PAN fiber is typically shipped in compressed bales (250kg-350kg each) to maximize container space. Negotiate for FOB (Free On Board) terms if you have a reliable freight forwarder, as this gives you better control over costs. For long-distance shipping, ensure the supplier uses moisture-proof and UV-resistant packaging to prevent fiber degradation during transit. Request 14 days of free demurrage at the destination port to allow for customs clearance flexibility.

For initial orders, utilize Letters of Credit (L/C) or Escrow-based payment systems provided by reputable B2B platforms to ensure funds are only released upon proof of shipment. Avoid 100% upfront T/T (Telegraphic Transfer) payments. A standard industry practice is 30% deposit and 70% against the Bill of Lading (B/L). Always verify the bank account details via a secondary communication channel (e.g., a video call) to prevent phishing scams.
