Escalating US-Iran Tensions Trigger Triple Shock to China's Hardware and Plastics Industries
Published: 2026-03-27
In March 2026, escalating military conflict between the US and Iran has disrupted shipping in the Strait of Hormuz, delivering a triple shock of soaring costs, supply shortages, and logistical chaos to China\'s hardware and plastics industries, relentlessly squeezing the profit margins of small and medium-sized enterprises (SMEs).
The Plastics Industry: On the Front Lines
The plastics industry has been hit first and hardest. International oil prices, the source of raw materials, surged over 6% in a single week, with Brent crude briefly breaking the $80 per barrel mark. For every $10 increase per barrel, the production cost for polyolefins like PP and PE rises by 300–500 yuan per ton.
Compounding the issue, Iran, a primary source for China\'s LDPE imports, has seen its shipments blocked. This has driven domestic LDPE spot prices up more than 10% in a week, with PP drawing-grade material seeing a similar near-10% increase. On top of this, doubled shipping insurance premiums and rising freight rates have added another 5–8% to the landed cost of imported raw materials.
⚙️ The Hardware Industry: Costs Climb in Tandem
The hardware industry is experiencing a parallel surge in costs. Prices for energy-intensive metals like aluminum and zinc have jumped due to higher smelting costs and market jitters, while copper prices have risen with supply chain disruptions, directly inflating the cost of raw materials for hardware components. Simultaneously, price hikes in plastic auxiliaries and coatings are further compressing profit margins.
A Widening Divide
A clear divergence is emerging within the industry. Leading enterprises with long-term supply contracts, futures hedging strategies, or alternative coal-chemical production capacity are demonstrating greater resilience. In contrast, smaller manufacturers, heavily reliant on imported materials and possessing weak bargaining power, are shouldering the burden, with some forced to reduce production loads.
