The recent tariffs increase in United States (US) have moved beyond headlines; they are now a day-to-day operational reality for multinational enterprises having business in the US. Whether importing electronics, luxury goods, or industrial machinery into the US, the cash flow and profitability impact of tariffs costs can be significant especially to low margin business. What is less immediately visible, yet critically important, is how these costs affect a company’s transfer pricing policies and profit allocation models.

While tariffs have historically been in place, recent increases may distort pricing strategies, making it necessary for companies to re-evaluate the arm’s length nature of their related party transactions. As a result, companies must now reassess how profits are allocated, margins are benchmarked, and intercompany pricing decisions are documented. This article outlines how tariffs changes are reshaping traditional transfer pricing frameworks and how companies should adapt in response.

Tariffs and Tested Party Profitability

The escalation of tariffs, such as a 26% duty on imports, can significantly distort the economics of an intercompany transaction. Even though tariffs are externally imposed, they affect internal profit allocation and the tested party’s performance under transfer pricing rules.

• Tariffs and Transfer Pricing: General Considerations

From a transfer pricing perspective, tariffs are generally treated as a legitimate operating cost when borne by the importer (often the US company). If the importer is also the tested party in the transfer pricing analysis, the tariff cost directly impacts its reported profitability.

OECD Transfer Pricing Guidelines [Chapter I, paras. 1.33–1.41 and Chapter III] support the inclusion of tariffs costs when determining arm’s length outcomes, provided the related risk is contractually and economically borne by the tested company. However, a sudden drop in profitability, even if tariff-driven, can trigger scrutiny by tax authorities, necessitating clear documentation and, potentially, realignment of intercompany pricing policies.

• Differentiated Impact by Operating Model

Tariff treatment depends heavily on the functional profile and risk allocation of the tested company. Key models include:

• • Limited-Risk Distributor (LRD): The LRD typically earns a routine return for limited functions performed and minimal risk assumed. If the LRD bears the tariff cost without a corresponding price adjustment, its margins may be compressed below the arm’s length range. If the risk of tariffs is allocated to the principal / the entrepreneur, the cost can be passed through, allowing the LRD’s profitability to remain stable.
  • Full-Fledged Distributor: In this model, the distributor assumes significant market, inventory, and credit risk and is entitled to greater upside potential. Tariffs borne by a full-fledged distributor are generally treated as part of its operating expenses. Any margin erosion due to tariffs should be substantiated through detailed transfer pricing documentation and potentially adjusted benchmarking.
  • Contract Manufacturer: If the contract manufacturer owns the raw materials and acts as the importer of record, tariff costs are added to its cost base and affect profitability. Conversely, under a toll or consignment manufacturing arrangement, the principal retains ownership of inventory and may also bear the tariff. In such cases, the manufacturer’s return remains unaffected. The correct treatment hinges on inventory ownership and contractual risk allocation.

• Incoterms and Tariff Risk: FOB vs. CIF

The importer’s identity and thus who bears tariff costs is influenced by the Incoterms that govern the intercompany transaction:

• • FOB (Free on Board): Under this term, risk and title transfer to the buyer (typically the US subsidiary / company) once goods are loaded at the port of shipment. The US company becomes the importer of record and is liable for tariffs. This cost becomes part of the tested party’s / US subsidiary’s operating expense and impacts its profitability unless it recovers tariffs costs as reimbursements.
  • CIF (Cost, Insurance, and Freight): In this case, the seller handles transportation, insurance, and may even handle import formalities depending on the agreement. If the foreign company / the seller remains the importer of record or arranges customs clearance, it may bear the tariff, potentially justifying a reduction in the transfer price to the US company.

These pricing arrangements must be clearly reflected in intercompany contracts, transfer pricing documentation, and customs filings to ensure consistency and defensibility.

Realigning Profit Expectations and Comparables in a Tariff Environment

The tested party, typically the least complex company such as an LRD or contract manufacturer, is expected to earn a consistent arm’s length profit percentage. However, rising tariffs can elevate costs and decrease profit margins. While the tested party itself generally remains unchanged, businesses must evaluate whether the transfer price between related party or resale price to end customer should be revised or both to adhere to arm’s length margin.

Industries most affected by tariffs typically include:

• Electronics and semiconductors
• Consumer goods and luxury items
• Automobiles and automotive components
• Machinery and industrial equipment
• Biotechnology and medical devices

These industries are highly dependent on cross-border supply chains, making them particularly susceptible to tariff exposure and profit volatility.

Note: While many finished pharmaceutical products are exempt from U.S. tariffs under international trade rules, certain raw materials, active pharmaceutical ingredients (APIs), and medical devices can be subject to tariffs, particularly in the context of trade disputes (e.g., U.S.-China Section 301 tariffs). Thus, pharma and biotech companies may still face indirect tariff exposure.

Cross-border services (such as IT, finance, or consulting services) are not subject to tariffs under international trade law. Tariffs apply only to tangible goods at the point of customs clearance, which helps shield service-based industries from direct tariff costs.

Refining Comparables

Economic analysis focus on choosing comparable companies with similar functions and risk profiles and if the tested party is subject to import tariffs, comparables that are not  subject to similar tariffs can distort the arm’s length comparability.

For instance, if a US LRD importing goods from Asia faces a 26% tariff, but the  comparable companies are domestic distributors or not subject to tariffs, then the comparison is flawed.

To ensure validity:

• Refine comparables to include importers or businesses with similar tariff exposure.
• Apply geographic filters to limit comparables to regions with similar trade policies.
• Adjust for material differences and clearly disclose reasoning in the benchmarking report.

Adjusting Intercompany Prices and Profitability

When tariffs reduce tested party margins, companies may consider adjusting intercompany prices to restore arm’s length outcomes to let principal company absorb the tariffs costs. While economically justified, such changes must be approached cautiously to avoid customs scrutiny.

1. LRD – An LRD earns a stable return. If tariffs are borne by the LRD, a reduction in transfer price from the principal may help maintain margins. However, customs authorities may view the sudden change of the import value as under invoicing.
2. Full-Fledged Distributor – For a full-fledged distributor, reduced transfer prices may be appropriate where tariffs significantly impact profitability. However, such pricing adjustments must be supported by detailed industry overview, economic analysis and aligned with comparable third-party selection.
3. Contract Manufacturer – When the US company is a contract manufacturer and also the importer of raw materials, the cost impact of tariffs may justify adjusting the purchase price. If the principal owns the goods and bears the risk, the contract manufacturer’s pricing and margin remain unchanged. Customs risks must still be assessed if the manufacturer is the importer of record.
4. Impacted Services Industries – While tariffs apply only to the cross-border trade of goods, service providers supporting tariff-impacted industries often face indirect consequences. When companies in manufacturing, retail, or import-heavy sectors experience rising input costs due to tariffs, they may respond with budget cuts, project delays, or operational scale-backs, affecting service contracts and profitability.

Examples of affected services include:

• Engineering firms that design equipment or machinery for car makers or factories may see fewer new projects if those clients delay expansion or stop investing due to higher material costs.
• IT and ERP providers supporting manufacturing and supply chain operations may face renegotiated service contracts or delayed rollouts.
• Marketing and consulting firms working with consumer goods and luxury brands may encounter cutbacks in campaign or expansion budgets.
• Shared services centres (finance, HR, compliance) may see shifting cost allocations if the business units they support face tariff-induced pressure.

Even though the services themselves are not subject to tariffs, these ripple effects can impact intercompany pricing, service levels, and documentation requirements. Transfer pricing policies for services should be revisited where margins or volumes are materially affected.

Customs Risk and Compliance Requirements

• Customs authorities focus on the declared import value. Sudden transfer price reductions tied to tariff changes may trigger audits.
• Inconsistencies between intercompany agreements and actual conduct can lead to penalties.

Best Practices for Implementing Price Adjustments

• Updated industry overview highlighting the impact of recent tariff changes on the relevant sector
• Use detailed economic analysis to support price changes.
• Ensure alignment across intercompany agreements, tax filings, and customs declarations.
• Conduct a fresh Transfer Pricing documentation that demonstrates the business rationale and economic substance behind any changes.

Illustrative Example: Determining Arm’s Length Pricing Under Tariff Pressure

The table below illustrates an US company as LRD US company which purchases goods from its overseas related party and sells them to independent third parties. The US LRD is expected to earn fixed arm’s length operating distribution margin say at ~8% on sales. For the purposes of raising the periodic invoices by principal to LRD, a backward calculation is generally followed starting from arriving the estimated third-party selling price to determine what the intercompany purchase price (COGS) should be under different assumptions.

Pre-Tariff:

Post Tariff under different scenarios:

Scenario A: No Adjustment to TP

• Increased Tariff cots is absorbed by the LRD.
• Purchase price remains unchanged at $1080, leading to margin compression.
• Justification of negative margins from TP documentation standpoint remains challenging.

Scenario B: Adjusted Transfer Price

• The intercompany transfer price is adjusted by Principal at $857.
• The principal company / manufacturer / entrepreneur company absorbs the tariff, and the LRD maintains its targeted margin.
• Variation in valuation as derived by Customs authorities remains a concern and this requires a documentation alignment.

Scenario C: Tariff as Reimbursable Expense

• The Tariff cost is recovered by LRD from principal as treated as pass through.
• Even though distribution margin calculation considers the tariff costs, but the recovery is added back making the margin constant.
• Intercompany agreements must explicitly allocate tariff risk to the principal; customs and TP filings must be aligned.
• This is often the most ideal approach for LRDs, as it preserves the intended arm’s length margin, minimizes pricing distortions, and clearly delineates risk, provided it is contractually supported and consistently documented.

Documentation: More Than a Compliance Obligation

• Local File: Clearly describe how tariffs affect the industry and tested party; explain any margin deviations.
• Master File: Include updates to the group’s supply chain, pricing models, and risk allocation.
• Intercompany Agreements: Accurately reflect tariff allocation in line with the actual conduct of the parties.

Thorough documentation ensures alignment across tax and customs regimes and provides a first line of defence during audits.

Conclusion: A New Lens on Profitability

While tariffs are imposed at borders, their effects ripple through supply chains, accounting practices, and profit allocation methods. This impacts not only the industries directly subject to tariffs but also those indirectly affected due to their reliance on such industries. They compel a transition from static pricing assumptions to more dynamic, economically responsive frameworks.

To remain compliant and resilient, companies must:

• Adapt transfer pricing models to reflect the financial impact of tariffs,
• Reassess their comparables and benchmarking filters,
• Strengthen contractual clarity and documentation,
• Coordinate positions across tax and customs to avoid mismatches.

This is no longer just about defending margins—it is about maintaining operational flexibility and regulatory alignment in a volatile global trade environment. The most agile companies will be those that treat transfer pricing not as a compliance exercise, but as a strategic lever in managing global value chains.
