Polyethylene Supply Structure Changes! Largest Import Source Faces Safety Issues, China's Import Dependency Analysis

The global polyethylene supply landscape is undergoing accelerated restructuring, with geopolitical risks hanging like a sword of Damocles. The Middle East—particularly Iran—as a core source of China's polyethylene imports, directly determines domestic supply-demand balance and price trends through its production capacity, export stability, and logistics channels. Although the UAE ranks as China's top nominal importer, a significant portion of these imports is actually transshipped Iranian material, meaning Iran's actual contribution far exceeds what the surface data suggests.

Core Impact Directly Tackles LDPE Structural Pain Points

• China’s overall polyethylene import dependency exceeds 29%, whereas LDPE import dependency stands at over 49%, significantly higher than that of HDPE/LLDPE (24–30%).

Iran accounts for 13.8% of China's total LDPE imports, offering superior quality and extremely strong downstream stickiness, making it a typical "essential and irreplaceable material."

• Although the import volume of HDPE is larger (accounting for about 49%), the variety is more dispersed and the substitutability is stronger, leading to a relatively mild impact; LLDPE, which accounts for only 11%, has the least impact.

Iran’s polyethylene (PE) production capacity exceeds 6 million tons per year, accounting for approximately 4% of global output. Its PE exports amount to about 2 million tons annually, over 60% of which are destined for Northeast Asia, with China being the largest importer. Should geopolitical risks escalate—leading to reduced Iranian exports or logistical disruptions—domestic LDPE prices in China would be the first to react, triggering significant speculative activity and a structural price increase; the broader PE market would likewise follow suit amid this sentiment-driven volatility.

This analysis deeply dissects the real impact of Iranian sources on China's polyethylene from three dimensions: supply structure, import source distribution, and variety substitutability, providing key judgment references for companies in the industrial chain, traders, and investors for 2025-2026: under the large trend of accelerating domestic substitution, Iranian LDPE remains a "gray rhino" that is difficult to bypass in the short term.
