In Bangkok’s automotive corridors, a quiet but consequential negotiation is unfolding. Honda, one of Japan’s most storied carmakers, has announced plans to invest Rp 6.4 trillion in Thailand, a move that underscores both the company’s commitment to the region and the challenges of competing in a rapidly shifting market. Yet the investment comes with a pointed request: a review of Thailand’s import duty policy, which currently imposes tariffs of up to 80 percent on vehicles imported from Japan, Europe, and the United States.
At the heart of Honda’s appeal is the question of fairness. Electric vehicles (EVs) and range-extended EVs from certain countries enjoy a zero percent import duty, giving them a decisive edge in price-sensitive markets. Koji Iwanami, President and CEO of Honda Automobile (Thailand), has made clear that Honda is not asking for parity at zero percent. Instead, the company seeks a reduction that would level the playing field and allow consumers to access Japanese models, such as the Honda Freed, Jazz, and Step WGN, at more competitive prices.
The stakes are high. Honda’s Prachin Buri plant, with an annual production capacity of 110,000 vehicles, is already operating near its limit. The facility supplies six core models to both domestic buyers and export markets spanning more than 70 countries. But capacity constraints mean Honda must continue importing completely built-up (CBU) vehicles, which are subject to the steep tariffs. Without relief, the company risks losing ground in a market increasingly defined by EV entrants and aggressive pricing strategies.
Honda’s lobbying effort is not an isolated campaign. Through the Japanese Chamber of Commerce in Bangkok, Honda has joined five other Japanese automakers in discussions with the Thai government on eight pressing issues. Among them, the excise tax policy for hybrid electric vehicles (HEVs) looms large. Honda has urged policymakers to align the timing of new tax rules with model launch cycles, ensuring that manufacturers have sufficient runway to integrate locally produced components, a requirement for tax reductions without disrupting product pipelines.
For Thailand, the dilemma is complex. On one hand, lowering tariffs could attract greater investment, sustain domestic production, and keep Japanese automakers firmly anchored in the country. On the other, it risks undermining local manufacturers and reducing government revenue. The broader context is Thailand’s ambition to position itself as a hub for EV production, a strategy that has already led to preferential treatment for certain foreign entrants. Balancing this vision with the need to retain long-standing partners like Honda will test the agility of policymakers.
The episode illustrates a larger truth about Southeast Asia’s industrial landscape: investment is no longer a one-way street. Companies bring capital, technology, and jobs, but they also demand policy environments that support competitiveness. Governments, in turn, must craft incentives that attract investment without eroding domestic industry. The negotiation between Honda and Thailand is emblematic of this new dynamic, where industrial policy and corporate strategy are intertwined in ways that will shape the region’s economic trajectory.
Honda’s Rp 6.4 trillion bet is about securing a foothold in a market where the rules of competition are being rewritten. For Thailand, the decision on tariffs will signal whether it intends to recalibrate its policies to retain legacy partners or continue prioritizing new entrants in the EV race.
