Marubeni Corporation is a Japanese sogo shosha (general trading and investment house) whose Metals & Mineral Resources division holds direct equity stakes in mining and smelting assets — iron ore, coal, copper, and aluminium — alongside its broader trading, energy, and infrastructure businesses.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 2 suppliers. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
Marubeni's own page: Marubeni Aluminium Australia 'Has 67,000 tpa equity aluminium ingot from Portland Aluminium smelters ... All ingots are exported to mainly Japan and Asian countries.' Portland smelter (Victoria, AU) is 55% Alcoa (operator) / 22.5% CITIC / 22.5% MAA. Equity-linked offtake, not a stake alone: MAA lifts its share of metal. Origin AU (Portland, VIC); destination 'mainly Japan' per Marubeni, so AU>JP is the stated principal flow, some tonnage goes to other Asian countries.
Marubeni's own page: MAA has '23,000 tpa equity aluminium ingot from Boyne Smelter (total 90,000 tpa)' and 'All ingots are exported to mainly Japan and Asian countries.' Boyne Island smelter (Gladstone, QLD, AU) is 73.5% Rio Tinto after its 2024 purchase of Mitsubishi's stake (Rio Tinto release 2024-09-30); Marubeni's interest is via Southern Cross Aluminium (Sumitomo/Marubeni JV, 7.71%). Equity-linked offtake; origin AU (Boyne Island), destination mainly JP.
Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
This company sits on the supply side for 5 of its 5 materials — a restriction on those is a tailwind, not a headwind.
As a producer, policy pressure across its produced materials is flat.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
No actions in the register have named or swept this company in the last 24 months.
