1. Core Drivers of High Iron Ore Shipping Volume

As the core raw material for the steel industry, iron ore ranks first in global dry bulk shipping (1.543 billion tons in 2023, accounting for 27.88% of dry bulk volume), driven by multiple economic, geographical, and industrial factors:
(1) Rigid Demand from Global Steel Industry
  • Industrialization Push: Emerging economies like China and India are in peak infrastructure construction. China's crude steel output reached 1.018 billion tons in 2023 (57.3% of global total), requiring over 1.5 billion tons of iron ore.

  • Sustained Steel Consumption: Long - term demand from automotive, construction, and machinery sectors keeps iron ore as "industrial food," with global steel apparent consumption reaching 1.8 billion tons in 2023.

(2) Geographic Mismatch Between Resource Distribution and Consumption
  • High Export Concentration: Brazil and Australia account for 82% of global iron ore exports (2023 data), with Australia's Port Hedland exporting 520 million tons annually.

  • Far East - Centric Imports: China, Japan, and South Korea account for 70% of global imports, with China alone importing 1.1 billion tons annually, requiring transoceanic shipping.

(3) Cost and Scale Advantages of Sea Freight
  • Optimal for Long - Distance Transport: Shipping from Brazil to China costs $15 - 20/ton, 1/3 of rail and 1/10 of road transport.

  • Popularity of Very Large Ore Carriers (VLOC): 400,000 - ton VLOCs reduce unit transport cost to <$10/ton, with over 200 VLOCs in service in 2023.

(4) Demand for Supply Chain Stability
  • Strategic Reserves and Inventory Cycles: Steel mills maintain 3 - 6 months of iron ore inventory, with Chinese ports holding 150 million tons year - round.

  • Limited Substitutes: Although scrap steel can partially replace iron ore, global scrap recycling rate is only 50%, concentrated in developed countries.

3. Future Trends of Iron Ore Shipping Volume

  • Short - term (2025 - 2027): China's steel demand plateaus, but India/Southeast Asia's industrialization drives 3 - 5% annual growth, expected to reach 1.7 billion tons by 2027.

  • Long - term (post - 2030): Technologies like hydrogen metallurgy may reduce demand, but global urbanization will keep shipping volume above 1.5 billion tons.
