Seasonal optimism lifts China’s polyolefin outlook despite lingering headwinds

China’s PP and PE markets are closing August on a largely steady note. While PE has managed to show some resilience, PP has continued to lag behind, with prices hovering around their two-year lows in recent weeks. Nevertheless, optimism is beginning to emerge as the traditional peak season of “Golden September – Silver October” approaches, encouraging sporadic improvements in downstream demand and lifting sentiment across the industry.

Demand slowly returns ahead of high season

Signs of recovery have started to surface in downstream demand, particularly from the food and cosmetics packaging sectors, which has lent support to market sentiment. According to market sources, the agricultural film market is now moving into its seasonal transition, while packaging film demand remains underpinned by basic requirements.

Players have also expressed optimism for the upcoming peak months. A trader based in Zhejiang opined, “We foresee a gradual improvement in demand as September and October approach,” reinforcing expectations of stronger consumption.

After a prolonged downtrend, many sellers are poised to capitalize on this opportunity by attempting price increases, justifying their moves with the anticipated seasonal pickup in demand.

But demand may still fall short of expectation

However, the extent of this recovery may be limited. Buyers remain inclined to purchase only on a just-in-time basis, preventing a broad-based resurgence in resin demand. The Zhejiang-based trader cautioned that demand at the converter level remains sluggish, with buyers only procuring for their immediate needs.

Broader downstream sectors are still grappling with weak end-user consumption, a long-standing drag on China’s economy. At the same time, global uncertainties, including US tariffs, continue to weigh on the outlook. The Golden Week holiday in early October is expected to shorten the working month and reduce market activity, potentially limiting the extent of any price hikes achieved during the high season.

Meanwhile, some market participants have raised concerns that downstream activity is not rebounding quickly enough to match the rapid growth in upstream capacity. A distributor observed, “While some downstream operations are gradually recovering, the scale of demand growth remains insufficient when compared to the vast production capacity being added.”

Oversupply further weighs on peak-season outlook

Indeed, ample availability continues to overshadow the market despite several maintenance turnarounds and production cuts. According to ChemOrbis Supply Wizard, China is adding 450,000 tons/year of new PP capacity and 800,000 tons/year of new PE capacity by the end of August, with further expansions of 800,000 tons/year of PP and 500,000 tons/year of PE anticipated in September.

A Shenzhen-based trader noted that new production facilities in East China have already started operations, adding to supply pressures, particularly in the PP raffia segment where availability is abundant. Furthermore, the Golden Week holiday is expected to contribute to a build-up in inventories, which could weigh heavily on post-holiday markets.

Eyes on further capacity-related measures

In the meantime, players are keeping a close watch on domestic policy directions. Market participants have pinned hopes on China’s ongoing efforts to phase out outdated facilities, which previously had a supportive impact on sentiment. A Zhejiang-based trader reported that discussions within the chemical industry are pointing toward large-scale maintenance programs and other initiatives aimed at curbing overcapacity—a strategy that some in the market have dubbed the industry’s “anti-involution.”
