Chinese Overcapacity: The Structural Overhang
China's polypropylene capacity doubled from 20 Mt in 2015 to approximately 48 Mt in 2024, with operating rates falling from 92% (2020) to 78% (2024), forecast to bottom near 70% by 2027 (FACT: CISA, 2026).
Chinese PP exports to Southeast Asia, the Middle East, and Africa are undercutting local producers. China exported approximately 3 Mt of PP in 2024, forecast to reach 8-10 Mt by 2028.
The rationalization cycle is beginning with 1.8 Mt/yr of small capacity expected to close in 2026-31, but new mega-cracker additions will more than offset closures.
Where the Consensus Is Wrong: Feedstock Volatility Creates Windows
The consensus focuses on Chinese overcapacity as a permanent price cap, but feedstock costs create volatility independent of capacity. PP comes from propylene monomer from steam crackers (naphtha/ethane). When crude or gas prices spike, PP costs rise.
North America PP prices rose 8.6% MoM in May 2026 primarily due to feedstock cost pass-through from Hormuz disruption effects (FACT: Plastics Technology, May 2026).
Global PP demand at 73.1 Mt in 2025, growing 3-4% annually, driven by packaging, automotive, and construction (FACT: Mordor Intelligence, 2026).
Regional Breakdown
China ($1,430/t): Dominant producer. Overcapacity-driven export push. Integrated refining-petrochemical complexes produce at competitive costs.
North America ($1,520/t): Balanced. Ethane cracking cost advantage. Operating rates 85-90%. Buyers should contract 6-12 months ahead.
Europe ($2,530/t): Structural deficit. High naphtha costs. Imports from Middle East and US. CBAM will add costs.
Middle East: Low-cost gas-based producer. Saudi Arabia, UAE, Oman supply export markets.
Procurement teams purchasing polypropylene in 2026 should prioritize supplier diversification, lock in annual volumes where possible, and monitor the shifting trade policy landscape. The structural themes outlined above will play out over 12-24 months, creating windows for renegotiation and hedging alike.
