Tier-N mapping is the discipline of tracing a product back through every processing step — assembler, component maker, mill, dye house, smelter, farm or mine — until you reach the raw material. It is the foundation on which Scope 3 accuracy, CSDDD due diligence and forced-labour screening all depend.
Without it, your supplier list stops at the companies that invoice you. That is typically 10–20% of the emissions and a fraction of the human rights exposure. Tier-N mapping turns an invoice list into an actual supply chain graph: who transforms what, where, with which energy source, and under whose ownership.
What you get
Multi-tier supplier graph
A node-by-node map from your Tier 1 suppliers down to Tier 3–4 raw material origins, with country, site, process step and ownership for each node.
Traceability confidence score
Each link is rated on evidence strength — declared, document-backed or physically verified — so you know which parts of the chain would survive an audit.
Risk overlay
Carbon intensity, grid mix, water stress, forced-labour region flags and regulatory exposure (CSDDD, UFLPA, EUDR) applied to every mapped node.
Priority intervention list
The specific nodes where mapping should convert into action: coal boilers in Tier 2, unverified Tier 3 origins, single-source dependencies.
Who this is for
- Apparel, textile, footwear and furniture brands with deep upstream chains
- Electronics and automotive groups exposed to component and mineral traceability rules
- Companies preparing CSDDD or UFLPA due diligence evidence
- Procurement teams whose Scope 3 stalls because Tier 1 will not disclose Tier 2
How we work
Cascade the request
We start from your Tier 1 list and cascade a short, structured disclosure request downstream in the supplier's own language, with a clear commercial rationale rather than a compliance threat.
Cross-validate
Declared links are checked against shipping records, certifications, invoices and production data — declaration alone is never treated as traceability.
Escalate to physical proof
On the nodes that carry the most emissions or the most risk, we escalate to on-site assessment with an internationally recognised verification body.
