Minsur S.A. is a Peruvian mining group (part of Grupo Breca) and the world's second-largest producer of refined tin.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 1 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.

Steinweg Baltimore (LME warehouse) and Phoenixx L.P.
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.
Another tracked dossier names this company as a counterparty in its own sourced disclosure — this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 986 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
KfW IPEX-Bank (German state development bank), 2018-08-31: 'The basis for the UFK guarantee and the involvement of KfW IPEX-Bank is a long-term offtake contract for the delivery of copper concentrates between the project company Marcobre S.A.C. and Aurubis AG of Germany'. Contracting seller is Marcobre S.A.C., 60%-owned by Minsur S.A.; mine is Mina Justa, Ica, Peru (PE); Aurubis primary smelting is at Hamburg (DE). Contract term not disclosed; no 2024+ confirmation found (Minsur AR2024/2025 do not name customers).
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship — most of the corpus has no named-counterparty block at all yet.
This company sits on the supply side for 2 of its 2 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.
🇺🇸 US accounts for 100% of severity-weighted pressure.
