Malaysia and Japan led mirror-reported measuring and checking instrument parts.
Process-control tools sit behind yield, quality and advanced semiconductor manufacturing. Public customs data does not cleanly isolate wafer inspection and metrology tools in one visible Taiwan table, so this brief uses a closer customs-code proxy. It is useful for direction, but the page should state that it is not a pure semiconductor-only metrology measure.

Evidence: The WITS mirror-flow page gives top exporters of measuring/checking instrument parts to Taiwan.
Note: The WITS mirror-flow page gives top exporters of measuring/checking instrument parts to Taiwan.
This is a source-labelled proxy. It uses mirror-reported exports to Taiwan rather than Taiwan MOF’s selected-commodity table and does not isolate semiconductor-only metrology equipment. Metrology means precision measurement and checking in production or testing.
