US Tariffs and the Structural Reckoning: Why International Groups Are Redesigning Their Cross-Border Architecture

A Trade Environment That Demands Structural Responses

The tariff environment of 2026 is no longer a policy debate. It is an operational reality that is forcing international groups to re-examine how they move goods, manage costs, and structure their cross-border entities.

With effective tariff rates on Chinese goods now exceeding 145%, a 25% duty on vehicles and parts, and metal tariffs reaching 50% on steel, aluminium, and copper derivatives, the cost of maintaining legacy supply chain configurations has become unsustainable for many businesses. The average tariff rate across all US trading partners stands at approximately 17% — the highest since the Smoot-Hawley Tariff Act of 1930\.

For companies that operate across borders, this is not simply a procurement problem. It is a structuring problem.

The Shift from China: Numbers That Speak for Themselves

US imports from China have returned to near-2001 levels. The diversification away from Chinese manufacturing, which began as a gradual trend, has accelerated dramatically. Companies are redirecting sourcing to Vietnam, India, Mexico, and other jurisdictions with more favourable trade positions relative to the United States.

But moving a supply chain is not just about changing a purchase order. It involves setting up or restructuring entities in new jurisdictions, renegotiating banking relationships, establishing compliant local operations, and ensuring that the new structure holds up under transfer pricing, customs valuation, and substance requirements.

Companies that treat supply chain diversification as a logistics exercise rather than a corporate structuring exercise will find themselves exposed to risks they did not anticipate.

Why Holding Structures Are Under Pressure

The tariff escalation has created a cascading effect on how international groups organise their holding and intermediate entities. Several factors are driving this:

• Transfer pricing recalibration. When tariffs change the cost base of goods entering a market, the entire intercompany pricing chain is affected. Groups that have not reviewed their transfer pricing policies in light of the new tariff environment risk both double taxation and customs disputes.

• Customs valuation scrutiny. Authorities are paying closer attention to how goods are valued as they cross borders. If an intermediate entity in the chain does not add genuine value, its existence in the structure becomes a liability rather than an advantage.

• Substance requirements. Jurisdictions that are used as intermediary points — whether for invoicing, warehousing, or re-export — increasingly require demonstrable economic substance. A shell entity that exists only to route goods will attract regulatory attention.

• Trade finance disruption. Letters of credit, trade receivables financing, and supply chain finance programmes are all sensitive to the underlying flow of goods. When those flows change, the financing structures must follow.

The Strategic Responses That Are Working

The international groups navigating this environment most effectively share several characteristics.

Dual-sourcing across trade blocs. For every critical component or product, they maintain at least two qualified suppliers in different countries or regions. This is more expensive than single-sourcing, but the insurance value is significant. Companies that had diversified supply chains before 2025 absorbed the tariff shock far more gracefully than those that were entirely dependent on a single manufacturing base.

Entity rationalisation. Rather than adding more entities to work around tariffs, well-advised groups are simplifying their structures. Fewer, better-capitalised entities with genuine operational substance are more resilient than sprawling networks of SPVs that were designed for a different trade environment.

Jurisdiction selection based on trade agreements. The share of US imports from Canada and Mexico claiming USMCA exemptions surged to nearly 86% in early 2026, producing effective tariff rates below 5%. Groups that can legitimately shift manufacturing or assembly to USMCA-qualifying jurisdictions are doing so. But the qualification rules are precise, and getting them wrong carries significant penalties.

Treasury and FX realignment. When supply chains move, so do currency exposures. A company that previously sourced primarily in CNY and sold in USD now needs to manage exposures in VND, INR, or MXN. Without updating the treasury and hedging framework, the savings from tariff avoidance can be eroded by currency losses.

The Legal Dimension: What Changed After February 2026

An important development occurred in February 2026, when the US Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not authorise the emergency tariffs imposed in 2025\. Following this ruling, certain IEEPA-based tariffs were suspended, creating a temporary window of uncertainty.

For international groups, the legal landscape around tariffs is now as important as the tariff rates themselves. Structures that were built to work around specific tariff regimes may need to be reconsidered if the legal basis for those tariffs changes. Conversely, companies that delayed restructuring while waiting for legal clarity now face the reality that the broader tariff architecture — Section 301, Section 232, and reciprocal tariffs — remains firmly in place.

What This Means for Businesses Structured Through the UAE, Singapore, and Hong Kong

For groups that use UAE, Singapore, or Hong Kong as their holding, trading, or treasury hubs, the tariff environment creates both risks and opportunities.

These jurisdictions offer strong trade connectivity, extensive double tax treaty networks, and established free trade zone infrastructure. But they must be used correctly. A trading entity in Dubai that re-invoices goods without adding value will not survive scrutiny. A Singapore holding company that exists only on paper will not provide the substance that tax and customs authorities increasingly require.

The companies that are best positioned are those that have built genuine operational capabilities in these jurisdictions — with real staff, real decision-making, and real commercial activity — and that can demonstrate the value their structures add to the overall supply chain.
