Polyester DTY Price Eases: 150D Spec Breaks Below 9,300 Yuan as Inventory Pressure Cascades Through Supply Chain

9,300 yuan per tonne. That was the price tag Kaishi Group put on its polyester DTY (150D/48F, AA grade, semi-dull low-elastic white yarn) on July 3, with a seven-day validity. Compared to the benchmark price of 9,318.75 yuan published by Shengyishe on July 2, it represents a drop of 18.75 yuan per tonne. The margin seems modest, but after a week of price stability, this adjustment is worth watching.

Supply Chain Signals Behind the Price Cut

Kaishi's offer is not an isolated pricing move. On July 1, Juxing Chemical had already quoted the same spec at 9,000 yuan per tonne, a spread of 300 yuan. An expanding price dispersion among different producers for the same spec typically signals a loosening supply-demand balance. According to Shengyishe's tracking, the DTY benchmark price edged down from 9,318.75 yuan between July 1 and 3, with actual transaction discounts likely larger.

For buyers, the downward pressure comes from two directions: first, upstream raw materials PTA and MEG have faced price headwinds recently, weakening cost support; second, downstream weaving mills, especially small and medium-sized ones in Jiangsu and Zhejiang, have seen operating rates decline month-on-month since late June, slowing their spot purchases of polyester filament yarn. Intermediate traders who accumulated inventories during the earlier high-price period now face depreciation pressure, increasing their willingness to sell and further depressing the market's transaction center of gravity.

The 150D Spec as a Pricing Anchor

The 150D/48F spec is one of the most liquid and mainstream in the polyester DTY market, and its price changes are often seen as a bellwether for the entire polyester filament yarn market. As a major domestic polyester producer, Kaishi's pricing adjustments can directly influence the pricing strategies of surrounding small and medium-sized mills. If the current 9,300 yuan offer cannot be absorbed by the market within the next week, a broader price follow-through is likely.

Looking at historical price ranges, DTY 150D was trading in the 9,500-9,800 yuan range during the same period in 2025. The current 9,300 yuan level is about 3%-5% lower year-on-year, reflecting that the recovery in textile end-demand has fallen short of expectations. In particular, fast-fashion brands' restocking pace in export orders has been conservative, prolonging inventory digestion time in the intermediate links of the chain.

Practical Implications for Procurement and Export

Price declines create different opportunities and risks for different market participants.

For Buyers - Current prices are at a cyclical low but may still have room to fall. Adopt a phased locking strategy rather than bulk hoarding. - Watch the price spread among producers for the same spec. The 300-yuan gap between Juxing's 9,000 and Kaishi's 9,300 offers a clear arbitrage opportunity, but verify product quality and delivery lead times first. - The seven-day price validity means a narrow window. Complete price comparison and contract signing within the validity period to avoid missing the low price.

For Exporters - Reference the current low domestic prices when quoting export orders. Consider lowering FOB quotes modestly to enhance competitiveness, but leave room for exchange rate fluctuations. - Monitor price linkages in Southeast Asia. If Chinese DTY prices continue to fall, it may transmit to polyester yarn import prices in Vietnam and Bangladesh. Communicate price adjustment mechanisms with overseas clients in advance. - Use the current domestic price trough to sign forward fixed-price contracts, locking in raw material costs for the next 2-3 months to hedge against potential price rebounds.
