Polyester Industrial Yarn, often called PIY, is an important material used in many heavy-duty and technical applications. Unlike regular textile yarn used for clothing, PIY is mainly used in products that need strength and durability. These include tire cords, conveyor belts, safety belts, ropes, geotextiles, and other industrial textiles. Because PIY is closely linked to infrastructure development, transportation, and industrial activity, changes in its pricing often reflect broader economic conditions. Understanding the PIY Price Trend helps manufacturers, traders, and buyers plan their production and purchasing decisions more effectively.

In the third quarter of 2025, the global Polyester Industrial Yarn market showed stable pricing with a slight upward movement. Prices increased by around 1% on average during the quarter. This stability was supported by consistent demand from key sectors such as tire manufacturing, geotextiles, and industrial textiles. By September 2025, the PIY price trend reflected good inventory management, steady PET resin costs, and regional differences in freight and currency movements.

This article explains the PIY price trend in simple language, looks at the factors that influenced prices in Q3 2025, and discusses what the near-term outlook may look like.
