Polyester Staple Fiber Price Divergence: Henan Kaijie's Quotation Far Exceeds Market Average, What Does It Signal?

On July 4, Henan Kaijie Water Treatment quoted polyester staple fiber at 15,500 yuan per ton, while the same day's benchmark from Shengyishe stood at 7,311.29 yuan. The gap is more than double. Such extreme price divergence is rare in the chemical fiber industry. It points not to overall market trends but to a neglected product dimension: differentiated pricing by specification and application.

Background

Henan Kaijie's quote is not for conventional textile-grade polyester staple fiber. Its product attribute is marked as "diameter 30mm," far exceeding typical spinning-grade fiber (usually 1.5-6 denier, corresponding to about 0.02-0.04mm diameter). A 30mm diameter polyester staple fiber is essentially a "chopped polyester fiber" used in water treatment, filtration media, concrete reinforcement, and other industrial fields, not traditional fabric production.

The quote is valid for only seven days and comes from a single supplier—Henan Kaijie Water Treatment Co., Ltd. This makes it unrepresentative of the broader market, more akin to a targeted quote for a specific order. By contrast, on July 2, the benchmark was 7,280.83 yuan/ton, and on July 4 it edged up to 7,311.29 yuan, a fluctuation of only 0.4%, indicating a stable market for conventional textile-grade polyester staple fiber.

Industry Implications

This price gap offers a dual warning for procurement departments and mills.

For buyers, the 15,500 yuan/ton quote should not be interpreted as a "price hike signal" for polyester staple fiber. If sourcing standard 1.4D×38mm textile-grade fiber, the market average remains around 7,300 yuan/ton. Misreading this quote could lead to poor procurement decisions, such as premature stockpiling or accepting unreasonably high prices.

For mills and traders, this case highlights the high added value of non-standard products. Industrial-grade chopped polyester fiber for water treatment or filtration, due to special specifications, small batch sizes, and higher processing difficulty, follows a completely different pricing logic from bulk textile raw materials. Gross margins are often 20-30 percentage points higher, though market volume is limited and customer stickiness is high.

From an upstream-downstream perspective, the price of textile-grade polyester staple fiber remains primarily driven by upstream raw material costs (PTA, MEG) and downstream demand from yarn and fabric orders. The stable quotes in early July suggest no dramatic shifts in end-use demand.

Practical Recommendations

For Procurement Departments - Strictly differentiate product specifications: Always confirm fiber denier/diameter, length, and silicon treatment before purchasing to avoid misapplying industrial quotes to textile-grade procurement. - Reference multi-source pricing: Anchor decisions on industry benchmarks from Shengyishe or China Chemical Fiber Information Network, and compare quotes from at least three suppliers. A single point quote should not drive decisions. - Pay attention to validity periods: Henan Kaijie's quote is valid for only seven days. For long-term procurement, request longer lock-in agreements from suppliers.

For Mills/Traders - Develop non-standard product capabilities: If capable of producing or processing chopped polyester fiber with 30mm or larger diameter, consider entering niche markets like water treatment, filtration, and construction reinforcement for higher margins. - Guard against market misinterpretation: When extreme quotes appear, proactively explain product differences to customers to prevent loss due to information asymmetry. - Optimize inventory management: Standard products with low price volatility can maintain normal inventory; non-standard items should be produced to order to reduce capital tied up.
