Strategic Choices for ASEAN Enterprises Under US Tariff Reshaping: Supply Chain Restructuring and Regional Resilience Building

The tariff pressure exerted by the United States on Southeast Asia, whether due to labor and overcapacity issues involved in Section 301 investigations or potentially expanding in the future to key minerals and robotics under Section 232, signals the deterioration of the "rule-based" regional trade order. This uncertainty is forcing ASEAN enterprises to shift from traditional cost competition models to more forward-looking strategic layouts.

In the short term, the main challenge for enterprises is the direct spillover of costs. Based on observations of past cases, although enterprises can consider passing on tariff costs to consumers, the convergence of tariff rates between different countries may dilute the loss of competitiveness for enterprises. However, the volatility of SCOTUS rulings has increased market expectations for further tariffs, meaning the risk of high or full pass-through remains.

From a long-term perspective, enterprises will focus on two core strategies: supply chain restructuring and market diversification.

First, supply chain restructuring is the most direct physical defense against trade barriers. Although evidence for "reshoring" is still weak, multinational corporations (MNCs) in multiple countries are leveraging the differences in US tariff policies to accelerate the transfer of some production and logistics centers within Southeast Asia to avoid potential additional barriers. This internal transfer will accelerate the integration of regional value chains and enhance the resilience within ASEAN.

Second, market diversification is the fundamental way to reduce dependence on a single market. Faced with ongoing uncertainty in the US market, ASEAN countries are actively promoting regional integration. The comprehensive review of RCEP, the conclusion of the CEPA between Indonesia and the EU, and the upgrading of cooperation between countries and the GCC are all key measures for enterprises to build a "de-risked" regional ecosystem. These regional trade agreements and cooperation frameworks aim to provide enterprises with a more stable and predictable growth environment by deepening intra-regional trade.

In summary, the fluctuations in US trade policy have not led to a large-scale exodus of ASEAN enterprises, but rather have prompted them to accelerate their transformation from "efficiency-first" to "resilience-first." The focus of enterprise strategy will shift from purely low-cost production to complex regional collaboration, localization adjustments of the supply chain, and active participation in shaping regional trade rules, thereby achieving sustainable business layouts amidst new geopolitical frictions.
