Iron & steelExporter A — one blast-furnace mill
The pressure
An EU buyer asked for actual embedded-emissions evidence for 2026 goods before the next shipment window.
Path taken
- Opened one working file for one installation and one reporting year
- Entered CN groups, production quantity, and fuel/electricity inputs with units
- Linked invoices and meter extracts to calculation nodes
- Cleared fail-closed QC blockers, paid once to lock, sealed the package
Outcome shape
Buyer received a sealed PDF/JSON/O3CI package with ruleset pin and SHA-256 integrity — not a spreadsheet thread.
Single Pack · USD 449 · one operator · one installation · one year
Preparation package only — not an accredited verification opinion or EU approval.
AluminiumExporter B — one smelter, two product lines
The pressure
Procurement wanted one defendable package for two CN families from the same plant without mixing scopes.
Path taken
- Kept one installation scope; linked both goods groups inside the same working file
- Recorded methodology decisions for allocation and electricity factor
- Resolved warnings with plain-language guidance before seal
- Shared a buyer link after lock — prior seals stayed immutable
Outcome shape
One paid file covered corrections after buyer questions; a second plant would need a new payment.
Single Pack · same-file corrections included
Evidence-linked operator dossier for independent review — not a verifier certificate.
Holding / multi-entityGroup C — parent holding, three operator entities
The pressure
Group compliance needed SSO for preparers plus separate seal scopes per plant — without silent entitlement sharing.
Path taken
- Scoped Enterprise Exclusive (SSO · SLA · Holding) via sales inquiry
- Mapped holding admin vs operator preparer roles
- Each sealed file still bound one operator, one installation, one year
- IdP federation planned under contracted cutover (Entra / Okta / Google)
Outcome shape
Holding contract for access and coordination; seal math stayed installation-scoped.
Enterprise Exclusive · from USD 12,000 / year · contact sales
SSO does not replace case ownership checks. No accredited verification claim.
CementExporter D — first CBAM reporting year
The pressure
Team had production data but no evidence lineage — buyer rejected an ad-hoc Excel pack.
Path taken
- Used readiness checklist and pre-flight workbook before opening the case
- Built evidence register with hash + support status on each material input
- Pinned calculations to a published ruleset version
- Verified seal hash on the public verify surface before handover
Outcome shape
Handover package was inspectable: calculation trace, evidence coverage, integrity manifest.
Draft free → pay at lock when ready to seal
CBAMValid prepares the package; an accredited verifier issues assurance where required.
