Federal contracts (USAspending, awards started in the last 180 days)
No contract award starting in the last 180 days was found for a recipient named exactly "TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD". Subsidiaries and differently-spelled recipients are not matched — search contracts.
Lobbying (Senate LDA, as client)
No LDA filing posted since October 2025 names "TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD" as the client. Filings under a subsidiary or trade-association name are not matched — search lobbying.
