our thesis

We build our passports from time-stamped and auditable documentation throughout the entire supply chain.

We provide diligent onboarding and risk management, and enable documentation and data management for every step. All fit for trades, audits and due diligence procedures.

what we do

Two ways we make critical minerals trustworthy.

It starts with the mine, and it stays with the material. One platform, two services that build on each other.

Grievance mechanism

Vetted mines.

Before a mine can issue anything, it clears an elaborate review — company, ownership, licences, ESG, assays and the site itself — scored against OECD standards, among others. Fossensis performs risk assessment and offers technical assistance for any next steps.

Every lot, verified at a glance.

One passport, recording every real event from pit to smelter. Origin, compliance and documents are scored — so a buyer can review it in a single look, including timelines, timestamps and actors involved.

how it works

Read a lot like a core sample.

Follow one example journey: a passport tracing a lot of ore from a vetted pit in Nigeria to a smelter in Europe — every layer a recorded, cross-checked event. The same chain holds for any critical mineral, and a passport can carry one lot or many.

01

It starts at a vetted mine.

The passport can only be opened by a mine that already cleared onboarding. Origin is captured at the pit — not reconstructed at the export shed.

02

Quality is claimed, then tracked.

A production assay opens a running quality record — later challenged by the buyer's own lab at discharge, and an umpire lab if they disagree.

03

Every handover is reconciled.

At export, weight and piece count are checked against the manifest. A mismatch isn't hidden — it surfaces as a flag on the passport.

04

Identifiers travel with the material.

Seals, tags and container numbers recorded at one event must match the next. The chain is only as strong as its continuity — so we check it.

05

Europe's checks, built in.

At the border, importer and commodity codes are validated against live EU registries — the evidence a buyer needs for their own due diligence.

06

The buyer verifies for themselves.

At Rotterdam, the buyer's lab confirms the grade. Because every claim is on the record, a dispute has a clear, neutral path to resolution.

07

What's left is an evidence pack.

When the smelter consumes the lot, the passport retires — leaving a full, tamper-evident trail an auditor, buyer or bank can rely on.

verification at a glance

Origin. Compliance. Documents. Scored.

A Fossensis passport isn't a folder to read through. It's an assessment you can act on — with the full evidence one click beneath it.

  • Every claim is sourced

    Each score traces to a document, an identifier match or a registry check — never an assumption.

  • A gap shows up as a gap

    Missing, expired or non-reconciling evidence lowers the score and is flagged — honestly, not hidden.

  • Built for EU reporting

    Built on the OECD Due Diligence Guidance, our material passports can be configured to support the EU Conflict Minerals Regulation, the EU Battery Regulation and RMI's CMRT/EMRT reporting.
