China's PET Bottle Grade Resin Market Remains Stable Amid Feedstock Price Declines

2026-06-02

As May comes to a close, China's polyester industry continues to face pressure from weaker feedstock prices and cautious downstream purchasing activity. Across the polyester value chain, most major raw materials and finished products recorded week-on-week declines. However, compared with several textile-related polyester segments, the bottle-grade polyethylene terephthalate (PET) market maintained relatively stable operating conditions, attracting increasing attention from market participants.

According to the latest data released by China Chemical Fiber Information Center (CCF), bottle-grade PET prices declined from RMB 8,489/ton on May 22 to RMB 8,248/ton on May 29, representing a weekly decrease of 2.84%. The price adjustment was largely in line with movements in upstream feedstocks, which also experienced downward pressure during the same period.

Feedstock Prices Move Lower Across the Polyester Chain

CCF's Polyester Industry Chain Weekly Index showed that the main polyester feedstocks all recorded declines during the week. PX decreased by 1.51%, PTA fell by 1.18%, and MEG recorded the largest decline at 2.96%. As raw material costs softened, downstream polyester products followed a similar trend, including filament yarn, staple fiber and bottle-grade PET resin.

Although the market experienced a broad correction in prices, the decline was not accompanied by a significant deterioration in operating rates. This suggests that producers continued to maintain relatively stable production plans despite weaker market sentiment and lower raw material costs.

Bottle-Grade PET Operating Rates Remain Relatively High

While prices moved lower, production activity in the bottle-grade PET sector remained resilient. According to CCF data, bottle-grade PET operating rates increased slightly from 81.5% to 81.9% during the week ending May 29. This level remained above polyester filament operating rates and was broadly in line with the overall polyester industry average.

The stability of operating rates indicates that bottle-grade PET producers have not implemented the same scale of production reductions seen in certain textile-related polyester sectors. From a supply perspective, the bottle resin segment continues to maintain relatively stable production levels within the broader polyester industry.

CCF also noted in a separate market analysis that some bottle-grade PET producers are considering capacity restarts or operating rate increases under current processing margin conditions. In addition, several new projects are progressing toward commissioning, reflecting continued activity within the sector.

Industry Focus Shifts Toward June Market Conditions

Since April, several polyester products have experienced production cuts as downstream buyers adopted a more cautious procurement strategy amid price volatility. According to CCF, polyester filament and polyester staple fiber operating rates have fallen to relatively low levels compared with previous years.

Against this backdrop, market participants are paying close attention to whether June could represent a turning point for polyester operating rates. Although uncertainty remains regarding downstream demand and inventory levels, the bottle-grade PET segment currently appears more stable than several other polyester categories.

Whether this trend continues will depend on a combination of factors, including feedstock costs, producer operating decisions, and developments across downstream packaging markets.

Oil Market Developments Continue to Influence Industry Sentiment

Beyond domestic supply and demand fundamentals, global energy markets remain an important variable for the polyester industry. Recent analysis published by Packaging Monthly highlighted that fluctuations in crude oil prices continue to influence the cost structure of key polyester feedstocks, including PX, PTA and MEG.

Although feedstock prices softened during the second half of May, industry participants continue to monitor crude oil market developments closely. Changes in energy prices can affect production costs throughout the polyester chain and may influence future pricing trends across PET markets.

For this reason, crude oil, feedstock movements, freight conditions and operating rates remain among the key indicators being watched by both producers and buyers as the market enters June.
