One figure captures the current state of the PET bottle chip industry: domestic annual capacity has exceeded 20 million tons, while actual downstream demand stands at only 12 million tons. With capacity utilization below 60%, roughly one out of every two tons of capacity is idle. Sanfangxiang's predicament is a microcosm of this supply-demand imbalance, not an isolated case.
The Cost of Overcapacity
Founded in 1980 and listed in 2003, Sanfangxiang acquired Hailun Petrochemical for 7.35 billion yuan in 2020 to pivot its core business. It was once the second-largest PET bottle chip producer in China. But from 2023 to 2025, the company posted cumulative losses exceeding 1.6 billion yuan, with a single-year loss of 885 million yuan in 2025. The direct cause: product margins crushed by a flood of new capacity.
Industry data shows 2023-2024 was a peak period for PET bottle chip capacity additions, with numerous new plants coming online. Downstream demand from beverages and packaging grew much slower. The resulting oversupply squeezed margins to near cost levels, with occasional negative spreads. Sanfangxiang also expanded during this period, trying to gain share through scale, only to see profits eroded.
More critically, the company's value chain covers only the PTA-to-PET bottle chip segment, with its core raw material PX entirely purchased from external suppliers. Any rise in PX prices directly compresses profits. Its trading revenue fell nearly 60% year-on-year in 2025, a sign that its core business has lost its profit-generating ability.
Dual Pressure from Debt and Guarantees
Beyond operating losses, Sanfangxiang faces significant debt risks. As of the latest filing, overdue debts from guarantees provided to subsidiaries total 522 million yuan, or 10.82% of net assets. A single 290 million yuan financing lease for Hailun Petrochemical has already seen rent defaults.
Even more concerning is the related-party receivables issue. At end-2025, the company had 3.561 billion yuan in accounts receivable from related parties, but had set aside only 107 million yuan in bad debt provisions—a provision rate below 3%. Auditors explicitly stated they could not obtain sufficient evidence on the recoverability of these amounts, meaning a large-scale write-off could severely impact net assets.
The controlling shareholder's shares have been frozen by judicial order; some were scheduled for auction but temporarily halted due to execution objections. The risk of a change in control remains. Credit rating agency Lianhe Ratings has downgraded Sanfangxiang's long-term credit rating to A- with a negative outlook.
Anti-Overcapacity Policy Offers Breathing Room
In the second half of 2025, Chinese regulators held meetings with major PTA and bottle chip producers, focusing on preventing cutthroat competition. The industry interpreted this as a signal that policymakers were stepping in to curb disorderly capacity expansion.
The impact appeared in Q1 2026: Sanfangxiang reported a net profit of 32.74 million yuan, reversing its losses. Meanwhile, geopolitical tensions in the Strait of Hormuz pushed up polyester chain product prices, improving margins. The company's stock price also temporarily moved above the 1-yuan delisting threshold.
But whether the turnaround is sustainable remains uncertain. The fundamental oversupply in PET bottle chips has not been resolved; government intervention provides a temporary floor, not a permanent fix. Sanfangxiang's single-chain structure and reliance on purchased PX remain structural weaknesses.
Industry Implications
Sanfangxiang's case is a wake-up call for the entire polyester industry: capacity expansion must consider supply chain completeness and resilience, not just scale. In a market shifting from growth to consolidation, players with a single link are most vulnerable.
The PET bottle chip sector is likely to enter a consolidation phase in the coming years. Companies with strong cost control and integrated chains will survive better. Those with short chains and high debt, like Sanfangxiang, still face delisting risk unless they complete debt restructuring or attract strategic investors.
