SunSirs: China PET Bottle Chip Prices Surge Today (April 28)

I. Prices (April 28, 2026)

Futures (Bottle Chip Main Contract PR): Closed at 8,706 RMB/ton, up 570 RMB (+6.80%); Intraday range: 8,430–8,948 RMB/ton, surging on heavy volume.

Spot Market (East China, Water Bottle Grade): Mainstream prices at 9,200–9,350 RMB/ton.

II. Factors Driving the Rise

Cost Side: Strong rally in PTA prices prompts a passive follow-up rise in bottle chip prices.

Crude Oil + PX Prices Remain at Elevated Levels

Geopolitical tensions in the Middle East and disruptions in the Strait of Hormuz have kept Brent crude oil consistently at a high range of $110–$120 per barrel, lending firm support to PX prices.

High PX prices lead to rigid PTA production costs, providing a strong fundamental basis for PTA producers to hold firm on pricing.

"Epic-Scale" PTA Maintenance Turnarounds + Force Majeure Events (The immediate trigger for today's surge)

Major industry leaders—such as Yisheng and Hengli—have initiated concentrated maintenance turnarounds or reduced operating loads: Yisheng has halted multiple production lines across its Dalian, Ningbo, and Hainan facilities, while Hengli has placed its Dalian line under maintenance. Collectively, these actions impact approximately 20% of the nation's total PTA production capacity.

PTA production in April is projected to see a year-on-year reduction of 300,000–400,000 tons. This has directly tightened spot market liquidity; PTA prices have rallied continuously throughout this week, surging once again today.

PTA accounts for over 70% of the production cost for bottle chips; consequently, any rise in PTA prices necessitates an upward adjustment in bottle chip ex-factory prices. Today, cost-side pressures alone drove an increase of at least 200–300 RMB/ton.

Supply Side: The spot market for bottle chips is "genuinely tight," with virtually no inventory available for sale.

Low Operating Rates + Maintenance/Force Majeure at Major Plants

The overall operating rate for bottle chip production stands at approximately 71%, with a weekly output of only 331,000 tons—a figure notably lower than the year-ago level.

Several major manufacturers are currently facing force majeure events or undergoing temporary maintenance. This has further reduced the actual volume of spot inventory available for circulation; consequently, traders are holding zero inventory and are reluctant to sell their limited stock.

Social Inventories at Low Levels: Virtually No Buffer

Following a sustained inventory drawdown throughout March and April, spot inventories in East and South China have hit their lowest levels in nearly three years. Should a concentrated restocking wave occur, the market would immediately shift into "panic buying" mode.

Manufacturers Maintain a Firm Stance on Pricing

With profit margins having recovered, major manufacturers are refusing to lower prices or engage in distress selling. They are issuing firm, non-negotiable quotes; furthermore, when spot supplies become tight, they are quick to implement immediate price hikes of 200–300—a dynamic clearly exemplified this very afternoon.

Demand Side: Concentrated Pre-Holiday Stockpiling and a Surge in Essential Demand

The Peak Beverage Season Coincides with Pre-Holiday Restocking

The period spanning late April through May marks the traditional peak season for the beverage industry. Consequently, downstream players—specifically beverage manufacturers and packaging material producers—are engaging in concentrated inventory replenishment, placing bulk orders and executing large-scale procurement.

The Deadline for Pre-May Day Holiday Stockpiling Arrives Today

Today marks the final day for concentrated inventory replenishment ahead of the May Day holiday. As a result, essential demand has surged explosively, leading to a sharp spike in market inquiries and transaction volumes.

Export Performance Continues to Improve, Diverting Domestic Supplies

In March, exports of PET bottle flakes reached 582,500 tons—a month-on-month increase of 35%. With a portion of available supplies being shipped directly overseas, the volume of material circulating within the domestic market has been further reduced.
