Navigating Disruption: How Thai Manufacturers Can Respond to Tariffs and Energy Volatility

Introduction

Organisations, particularly those in Thailand’s manufacturing sector, are facing an unprecedented period of disruption. The convergence of unfavourable tariffs and fragmented supply chains is reshaping the competitive landscape across industries.

As one of Southeast Asia’s most export-driven economies, Thailand is especially vulnerable to these global shifts. What were once cyclical challenges are now evolving into structural changes that impact both local production and international trade.

Rising Trade Barriers Are Reshaping Global Competition

A fundamental transformation is underway in global trade. The return of protectionist policies, particularly in major markets such as the United States, has driven sustained tariff increases on exports from manufacturing hubs, including Thailand.

These rising tariffs are placing significant pressure on competitiveness and profitability. More importantly, they reflect a longer-term geopolitical realignment rather than short-term policy adjustments.

Blockage and Dispute: The Impact of the Strait of Hormuz

The surge in energy costs following disruptions in the Strait of Hormuz, coupled with raw material shortages affecting inputs such as plastics, aluminium, and chemicals, has created immediate challenges for Thai manufacturers.

This threatens the foundation of Thailand’s export economy, with sectors such as electronics, automotive components, petrochemicals, food processing, and garments facing heightened risk.

Although diplomatic access for Thai-flagged vessels offers some relief, the overall cost structure of manufacturing has shifted significantly. With Brent crude exceeding US$110 per barrel and global LNG supplies reduced by 20%¹ manufacturers must prepare for continued disruption over the next two to three quarters.

Five Cascading Impacts on Thai Manufacturing

Energy Cost Shock

Thailand’s reliance on Middle Eastern petroleum feedstocks has forced production cuts and temporary shutdowns in petrochemical operations, including olefins plants operated by Siam Cement Group².

If conditions worsen, refinery margins will face increasing pressure as operators are forced to procure crude at elevated prices.

If the situation escalates further, gross refinery margins would face significant downward pressure due to rising production costs, as refineries must purchase new crude oil at elevated prices.

Petrochemical and Plastics Input Disruption

The Middle East accounts for approximately 30% of global seaborne LPG exports and a significant share of naphtha supply. Prolonged disruption has tightened global availability of these key inputs.

For Thai manufacturers, the impact is immediate. Industries ranging from plastics and electronics to pharmaceuticals and garments are experiencing mounting supply chain stress³.

LNG and Electricity Supply Pressure

Disruptions in the Strait have significantly reduced LNG flows. Shipments from Qatar and the UAE have dropped sharply following the shutdown of the Ras Laffan facility⁴.

Given Thailand’s dependence on LNG imports, the country is seeking alternative sources, including the United States and Myanmar. Policy responses may include prioritising domestic gas, increasing coal and hydropower output, and introducing tiered electricity pricing.

Aluminium, Fertiliser, and Raw Material Constraints

The Gulf region plays a critical role in global aluminium and fertiliser supply. Reduced exports have driven up prices, with urea increasing by 50% since early 2026⁵.

This has downstream implications for automotive, electronics, and food processing sectors, all of which rely heavily on these inputs.

Shipping, Freight Rates, and Port Congestion

The effects on freight typically emerge within two to five weeks. Diverted shipping routes lead to port congestion, container imbalances, and increased logistics costs.

These disruptions constrain export capacity and add further pressure to manufacturers already managing rising input costs.

From Cost Pressure to Strategic Recalibration

The challenge today lies not only in the scale of disruption, but in its simultaneity. Tariffs, energy volatility, and supply chain fragmentation are no longer isolated risks. They are converging forces that amplify one another.

Traditional responses such as cost-cutting or supplier diversification remain relevant but are no longer sufficient on their own. The margin for error is narrowing, and the ability to respond quickly is becoming a key differentiator.

Resilience, in this context, is no longer purely operational. It is increasingly digital.

Why Visibility and Agility Are Becoming Non-Negotiable

A major constraint for many manufacturers is limited real-time visibility across operations. When costs fluctuate rapidly or shipments are delayed, reliance on siloed or outdated data can lead to costly missteps.

Leading manufacturers are now prioritising:

End-to-end visibility across procurement, production, and distribution
Real-time financial insights to track margin impact
Scenario planning to respond to external shocks
Integrated systems that reduce reliance on manual processes

This represents a fundamental shift in how manufacturing organisations operate under uncertainty.

Technology as a Buffer Against Volatility

While technology cannot eliminate geopolitical or supply chain risks, it can significantly mitigate their impact.

Cloud-based ERP systems enable manufacturers to unify financials, inventory, procurement, and production within a single platform. This creates a reliable source of truth and supports faster, more informed decision-making.

Integration and automation platforms further enhance responsiveness by connecting systems across the organisation and supply chain.

In practical terms, this enables:

Faster adjustment of production plans
More accurate demand forecasting
Improved cost control through real-time tracking
Stronger collaboration across teams and partners

Turning Uncertainty into a Strategic Advantage

Disruption often distinguishes reactive organisations from adaptive ones. While some manufacturers focus on short-term cost containment, others are using this period to modernise operations and strengthen long-term resilience.

This is where experienced regional partners can add value.

PS Global Consulting supports manufacturers across Southeast Asia in enhancing visibility, streamlining processes, and implementing scalable cloud-based systems tailored to regional complexities.

By aligning technology with business strategy, manufacturers can better navigate uncertainty, sustain competitiveness, and identify new growth opportunities.

Looking Ahead

Tariff pressures and energy disruptions may persist in the near term, but they also signal a broader transformation in global manufacturing.

For Thai manufacturers, success will depend on the ability to adapt not only operationally, but structurally.

In an environment defined by constant change, the ability to see clearly, act quickly, and scale efficiently may prove to be the most critical advantage.
