CBAM Readiness / Préparation CBAM: the bottleneck has moved to supplier data
The strategic question is no longer whether CBAM matters; it is whether your suppliers can produce decision-grade emissions data before contract renewal cycles tighten. By mid-2026, the European Commission's definitive-period rules and authorised declarant framework are already in force, which means importers are now exposed less by legal ambiguity than by weak supplier reporting discipline. Q3 should be used to stress-test actual-emissions datasets, fallback logic, and document ownership for every non-EU steel, aluminium, and fertilizer lane. Buyers that wait until annual declaration season will be forced into conservative assumptions, overbuy certificates, or reopen supplier negotiations at the worst possible moment.
