Semiconductor tooling approvals — localisation can be the real choke-point
Export controls increasingly attach to tooling, services, and approvals — not just chips. For supply chain risk, the highest leverage question may be ‘who can approve/process’ rather than ‘who can supply’.
Reader guide
How to read this Signal
Evidence → Uncertainty → Trigger → Decision implication
Each Signal separates the sourced change from what remains uncertain, identifies the trigger to watch and states why it matters to a decision.

Key points
What the evidence indicates for the decision.
- →Tooling and process approvals create hidden dependencies that are hard to substitute under time pressure.
- →Localisation efforts can reduce exposure but may increase lead time and capex.
- →Risk registers should track approvals/know-how constraints, not only component sourcing.
Control
Actions
Practical next steps if this Signal touches your mandate.
- 01Add ‘tooling/approval dependency’ checks to critical supplier assessments.
- 02Map single-points of failure across process steps (design, fab, packaging, test) and associated approvals.
