Southeast Asian PP Imports at a Crossroads as Chinese Sellers Raise Offers

Southeast Asia’s imported polypropylene (PP) market was largely stable in early October, with weekly average prices for homo-PP raffia, homo-PP injection and PP block copolymer (PPBC) injection remaining close to five-month highs,However, the rally that began in July has gradually weakened as high prices discourage fresh purchases, despite continued support from upstream costs.

Trading remained quiet during the first week of October as Chinese suppliers were largely absent for the National Day holiday from October 1–7. Their return brought higher PP offers, shifting market attention to whether these increases can be sustained. Given China’s leading role in Southeast Asia’s homo-PP imports and its expanding presence in PPBC, its pricing decisions could significantly influence the region’s near-term market direction.

Firm Feedstock Costs Meet Weak Buying Interest

Southeast Asia’s PP market continues to face conflicting pressures from rising upstream costs and sluggish downstream demand. Propylene prices have maintained an upward trend, supporting PP offers and limiting sellers’ scope to reduce prices.

Meanwhile, Brent crude futures have remained well above $100/bbl, and uncertainty surrounding the Middle East conflict has further encouraged suppliers to defend current price levels.

However, stronger production costs have not generated another substantial market increase. After almost three months of price gains, buyers have become increasingly reluctant to accept elevated offers, with some considering current levels too expensive.

Without clear evidence of stronger end-user demand, many converters are purchasing only to cover immediate requirements, while others are postponing deals in anticipation of a possible correction.

This cautious approach has restricted spot trading and made it harder for sellers to pass on additional cost increases. Although high replacement costs have helped prevent significant price reductions, weak demand has also limited the potential for further gains.

As a result, regional import prices have remained broadly stable, with market direction increasingly dependent on changes in upstream costs and the availability of competitively priced cargoes.

Chinese Suppliers Return With Higher Offers

China’s PP market reopened after the National Day break with stronger-than-expected momentum. A sharp rally in Dalian futures, manageable post-holiday inventories and renewed energy-market support improved domestic sentiment and encouraged some buyers to replenish stocks.

The stronger market tone was also reflected in Chinese PP offers to Southeast Asia, which increased after a week of limited fresh quotations during the holiday period.

The sustainability of these higher offers will depend on developments in Dalian futures, energy prices and domestic Chinese market conditions as trading activity returns to normal. If these factors continue to support prices, Chinese exporters may pursue further increases in Southeast Asia, potentially strengthening the existing price floor.

China’s export pricing will therefore be a key indicator of whether regional PP prices can remain near their recent highs or face renewed pressure.

China’s Dominant Supply Position Shapes Regional Trade

Data shows that China has been Southeast Asia’s largest homo-PP supplier since 2024, well ahead of other major origins such as Saudi Arabia and South Korea. During the first half of 2026, Chinese homo-PP shipments to the region exceeded 800,000 tons, accounting for approximately 45% of total imports.

This substantial share leaves Southeast Asia particularly sensitive to changes in Chinese export availability and sellers’ pricing strategies.

China’s influence has also expanded in the PPBC segment. It ranked as Southeast Asia’s second-largest PPBC supplier after South Korea during the first half of 2026, with shipments exceeding 100,000 tons. This volume had already surpassed China’s total shipments for the whole of 2025 and represented around 18% of regional imports.

Although China’s influence remains stronger in homo-PP, its growing presence in PPBC has further increased its importance in determining regional market trends.

Will Higher Chinese Offers Hold?

China’s return to the export market has brought higher offers rather than the downward pressure that additional supply might otherwise have created. However, Southeast Asian buyers remain resistant to elevated prices, making it uncertain whether the new offers will translate into sufficient concluded deals.

As trading activity normalizes, Chinese exporters will need to balance their efforts to maintain higher prices against the need to secure sales volumes. If futures, energy costs and domestic conditions remain supportive, Southeast Asian PP prices could consolidate around recent highs or resume their upward movement. Conversely, persistent buyer resistance and limited downstream demand could prevent further increases and leave the market vulnerable to a renewed correction.
