US reciprocal tariffs hit Japanese investors in Vietnam through two channels: directly — goods exported from Vietnam to the US face higher duties, eroding margins; indirectly — supply chains (components from Japan and China assembled in Vietnam) face inflated costs and disruption. This is a global trade risk, not Vietnam-specific — but factories in Vietnam exporting to the US feel it most directly. Response starts with reassessing supply-chain structure, not litigation.
In-depth analysis
How to shield supply chains from reciprocal tariffs? Four directions: (1) diversify export markets, reducing single-market dependence; (2) raise Vietnamese value-added and meet origin rules to enjoy FTA preferences (CPTPP, EVFTA, RCEP); (3) renegotiate price terms with customers (sharing the duty burden); (4) consider partial production relocation — but weigh switching costs against duty costs. ISDS over reciprocal tariffs? Very difficult — tariffs are a sovereign regulatory right, and ISDS governs investor–host-state (Vietnam) relations, not third-country (US) policies. The practical path is policy advocacy through associations, FTA utilisation and supply-chain restructuring — litigation is not the answer to tariff risk.
