This Insight looks at issues facing Irish, UK, and EU exporters to the USA considering the 2025 Tariffs.  Our next Insight will look at the legal issues in detail and contain links to the cases mentioned below.

As of the start of 2026, U.S. tariffs announced and implemented in 2025 remain a live commercial and financial reporting risk for EU, UK, and Ireland exporters to the United States because:

  • The U.S. implemented a broad, emergency-powers tariff program under the International Emergency Economic Powers Act (IEEPA, 50 U.S.C. § 1701 et seq.), including a 10% baseline tariff concept and additional country-specific rates, principally via Executive Order 14257 (April 2, 2025) and related amendments, and separate IEEPA “trafficking” tariffs via Executive Orders 14193, 14194, and 14195.
  • The U.S. also expanded sector/national security tariffs under Section 232 of the Trade Expansion Act of 1962 (19 U.S.C. § 1862)—notably on steel, aluminium, autos/parts, and copper—that are largely unaffected by the IEEPA litigation risk.

The IEEPA tariff program is subject to major legal uncertainty. In V.O.S. Selections, Inc. v. Trump, the U.S. Court of Appeals for the Federal Circuit (en banc) held that IEEPA’s authority to “regulate” imports does not authorize the breadth of tariffs imposed by those executive orders, affirmed invalidity, vacated a universal injunction in light of Trump v. CASA, Inc., 145 S. Ct. 2540 (2025), and stayed practical relief while Supreme Court review proceeds. The Supreme Court set argument for November 5, 2025, and heard argument; a decision is expected in 2026.

The EU and UK obtained targeted trade framework modifications late in 2025:

For the EU, Executive Order 14346 (September 5, 2025) and a Commerce/USTR HTSUS amendment notice (effective September 25, 2025; with key retroactive effective dates) created a structure where certain EU-origin categories (e.g., civil aircraft/parts; certain pharma inputs; certain “unavailable natural resources,” including cork) are returned to MFN-only treatment, and EU autos/parts are effectively calibrated to a combined 15% outcome under a modified Section 232 mechanism depending on MFN rates.

For the UK, the U.S. left a 10% baseline tariff on most goods while providing sector relief for autos and metals through a UK framework arrangement described in U.S. government summaries.

Accounting/tax bottom line for exporters (EU/UK/Ireland): Even where the exporter is not the importer of record, 2025 tariffs created 2026 accounting issues primarily through (i) pricing concessions and rebates (ASC 450 / ASC 606 interaction), (ii) inventory and impairment risk driven by demand shifts (ASC 330 / ASC 360), and (iii) transfer pricing redesign and customs-valuation alignment (IRC § 482; 19 U.S.C. § 1401a; IRC § 1059A; Treas. Reg. § 1.1059A-1).

1) What “Trump’s 2025 tariffs” are:

A. The IEEPA “reciprocal tariff” program (global baseline + country-specific rates)

The 2025 program most relevant to EU/UK/Ireland exporters was a global reciprocal tariff initiative announced April 2, 2025, under Executive Order 14257, imposing a baseline 10% ad valorem duty on imports from nearly every country, with scheduled additional country-specific rates ranging up to 50% for certain partners, and later modifications that paused and reactivated elements of the program. Key modifying instruments included Executive Order 14266 (April 9, 2025) suspending additional country-specific duties for most countries temporarily, and later orders pausing enforcement until early August 2025.

From a January 2026 perspective, the most important characteristic is that these IEEPA tariffs are operationally in effect but legally contested.

B. The IEEPA “trafficking” tariffs (Canada/Mexico/China)

Although not directly “Europe-targeted,” these tariffs mattered indirectly to EU exporters because they changed global pricing and sourcing dynamics. They were imposed via Executive Orders 14193, 14194, and 14195 (February 1, 2025), with later modifications (including China increased to 20% via Executive Order 14228).

C. Section 232 sector tariffs (metals, autos/parts, copper)

Separate from IEEPA, the U.S. relied on Section 232 (19 U.S.C. § 1862) and existing proclamations (as amended) to maintain high tariffs on metals and autos/parts, and to cover copper. Executive Order 14346 explicitly ties its framework implementation to both the IEEPA national emergency and to reducing or eliminating national-security threats identified in metal/auto/copper proclamations.

As of January 2026, Section 232 tariffs are generally viewed as more legally durable (and were explicitly described as unaffected by the IEEPA litigation).


2) Where the law stood in January 2026 (IEEPA litigation posture)

A. The core case and the legal principle

In V.O.S. Selections, Inc. v. Trump (Federal Circuit, decided August 29, 2025), the court held that IEEPA’s grant of authority to “regulate” imports does not authorize the challenged tariffs imposed by five executive orders (including the trafficking and reciprocal tariffs), and affirmed declaratory relief that those orders are invalid as contrary to law.

The court also vacated the Court of International Trade’s universal injunction and remanded considering Trump v. CASA, Inc., 145 S. Ct. 2540 (2025) (limiting universal injunctions), which matters because the form of relief can affect who can practically obtain refunds and how quickly.

B. Supreme Court status as of January 2026

The Supreme Court fast-tracked the IEEPA tariff challenge and set argument for November 5, 2025, which has occurred; a decision is expected in 2026.

C. Why this mattered to exporters (even though they often don’t pay duties)

Even if your EU/UK/Ireland entity is not the importer of record, the litigation creates practical consequences in 2026:

U.S. customers may negotiate “tariff invalidation” clauses or contingent rebates.

Your group may face requests for retroactive credits if duties are later refunded.

Pricing may become volatile because buyers’ model “tariff on / tariff off” scenarios.

From a financial reporting lens, that is where ASC 450 and variable consideration dynamics tend to appear on the exporter side.


3) The EU (including Ireland): how 2025 tariffs affected Europe, viewed from 2026

A. EU exposure in 2025: elevated reciprocal tariff risk, then a framework-based partial normalization

EU-origin goods were in the population potentially subject to the reciprocal tariff regime. By late 2025, the EU entered a framework that materially changed treatment for certain categories and created a more structured outcome for autos/parts.

The key legal instruments were:

Executive Order 14346 (September 5, 2025), which modified reciprocal tariff scope and created procedures for framework agreements, relying on IEEPA, the National Emergencies Act, Section 232, and related authorities.

Commerce/USTR HTSUS amendment notice (published September 25, 2025), implementing tariff-related elements of the U.S.–EU framework. It: Exempted certain EU products from the reciprocal tariff imposed by Executive Order 14257 (as amended).

Provided MFN-only for “unavailable natural resources (including cork), all aircraft and aircraft parts, and generic pharmaceuticals and their ingredients and chemical precursors,” and Modified Section 232 auto/parts tariffs to reach a combined 15% outcome in many cases depending on the MFN rate.

B. Ireland is treated as EU origin for these EU framework modifications

The implementing HTSUS notice lists EU member countries covered for these provisions and explicitly includes Ireland.

So, for “Ireland” specifically (as an exporter location), the practical analysis is Ireland is generally inside the EU framework umbrella for products that meet EU-origin and scope requirements.

C. Sectoral implications within Europe (the real driver of exporter impact)

i) Civil aircraft and parts (Europe-wide, including Ireland/UK components in EU supply chains) 

EU civil aircraft and parts meeting the scope criteria were carved back toward MFN-only treatment via the new HTSUS framework mechanisms (and linked to the WTO civil aircraft framework concept through HTSUS General Note 6 references in the implementing language).

Exporter consequence: more stability in forward pricing, but also more classification/scope compliance sensitivity (you must be in the right HTSUS lanes and satisfy scope limitations).

ii) Pharma and ingredients/precursors (especially relevant for Ireland) 

The EU framework provides MFN-only treatment for “generic pharmaceuticals and their ingredients and chemical precursors” and references “non-patented articles for use in pharmaceutical applications” in the broader aligned-partner approach.

Exporter consequence: Ireland’s pharma-heavy footprint can be comparatively insulated if products fit the scope; however, 2026 planning still needs to treat pharma as politically sensitive (i.e., risk of future Section 232 expansion even if not fully implemented in 2025).

iii) Autos and parts (high impact for industrial Europe) 

The EU framework’s auto/parts approach is best described as: MFN ≥ 15% ⇒ no incremental 232; MFN < 15% ⇒ 232 reduced to make MFN + 232 = 15% for covered EU autos and parts.

Exporter consequence: EU auto exporters moved from a “25% 232 world” to a “15% combined world” for covered products—material but not tariff-free.

iv) Metals and metal-intensive manufacturing

Europe’s metal-intensive exports remained under significant pressure because high Section 232 metal tariffs were not broadly removed by the EU framework (and metalswere a focal point of 2025 tariff policy generally). Also, many metal derivative products pull tariff exposure into downstream industrial products.

Exporter consequence: pricing concessions and volume risk concentrate in metals-heavy and machinery-heavy European exporters.

D. EU retaliation and export restrictions (why EU exporters had to monitor both sides)

In response to U.S. measures, the EU also adopted countermeasures under Regulation (EU) No 654/2014, implemented in 2025 via Commission implementing regulations that include not only additional duties but also an export prohibition to the United States for specified EU-origin products effective September 7, 2025.

Exporter consequence: beyond U.S. tariffs, certain EU exporters faced a hard constraint: “can we legally ship?”—which becomes a revenue, inventory, and impairment issue.


4) The United Kingdom: how 2025 tariffs affected UK exporters, viewed from 2026

A. The UK’s “baseline + targeted relief” profile For UK exporters, the 2025 posture is commonly summarized as:

  • A 10% tariff on most goods (reciprocal baseline staying in place), and
  • Relief mechanisms in certain sectors (autos, metals) under a UK framework arrangement announced May 2025.

B. Autos: quota-style relief concept and pricing implications

Public reporting described a structure where the U.S. reduced duties on a set number of British cars to 10% for a capped volume, with a higher rate above the cap.

Exporter consequence: UK auto exporters’ realized pricing and volume economics depended on whether exports were within the preferential volume. That tends to produce:

  • contract renegotiations with U.S. distributors,
  • channel conflict (allocation of quota among customers), and
  • variable consideration / rebate programs.

C. Metals: UK treatment more favourable than “global,” but still a major cost driver

Even where UK metals treatment is better than global, metals remain a primary area of tariff friction under Section 232 logic (national security framing), and metal derivative products can amplify impact.

Exporter consequence: even if you are not exporting raw steel/aluminium, you may be exporting machinery or components whose competitiveness in the U.S. depends heavily on metal input costs.


5) Accounting and tax implications for EU / UK / Ireland exporters (2026 viewpoint)

This section is written from the exporter’s point of view, but with the reality that many exporter groups consolidate U.S. importers/distributors.

A. Inventory costing (ASC 330) — when it matters to an exporter

Core concept: tariffs are paid by the importer of record. For a pure exporter selling FCA/FOB/etc. and not acting as importer, you usually do not record U.S. tariffs as your inventory cost.

However, ASC 330 becomes relevant in 2026 for exporters in two common structures:

You sell DDP or otherwise act as importer of record (you, the exporter, bear duty). 

You consolidate a U.S. importing affiliate (your group bears the duty economically and records it in consolidated COGS).

Accounting guidance commonly treats tariffs incurred directly in connection with acquisition of goods as part of acquisition cost under ASC 330-10-30-1, increasing inventory and flowing into COGS when sold; and tariffs are generally not considered “abnormal costs.”

2026 exporter-facing implication: even if your EU entity doesn’t capitalize tariffs, your consolidated group may see:

  • higher inventory balances at the U.S. importing entity,
  • lower gross margin as tariff-bearing inventory sells,
  • and increased risk of inventory impairment under lower-of-cost-or-NRV logic.

B. ASC 450 contingencies — where exporters most often have exposure in a tariff year

Exporters tend to encounter ASC 450 not because “tariffs might change,” but because tariff volatility drives claims, rebates, disputes, and refund-linked arrangements.

i) Customer pricing concessions and rebate programs

If your U.S. customers demand tariff relief, exporters frequently implement:

  • invoice-level credits,
  • end-of-quarter rebates,
  • “Tariff sharing” arrangements,
  • or contingent rebates triggered by legal changes (e.g., “if tariffs are struck down”).

These structures create ASC 450 questions when they resemble claims or loss contingencies (especially if you dispute the obligation) and ASC 606 questions when they are better viewed as variable consideration / reductions of transaction price.

ii) Litigation-driven “tariff invalidation” clauses (IEEPA uncertainty)

Because the IEEPA tariffs are being litigated and were held unlawful by the Federal Circuit in V.O.S. Selections (with relief stayed pending Supreme Court review), some counterparties in 2026 will treat tariff costs as potentially temporary and seek contingent economics.

Exporter accounting exposure arises if you:

  • promised retroactive price relief if tariffs are invalidated,
  • agreed to share in refunds received by the U.S. importer,
  • or embedded refund-sharing in distribution agreements.

iii) Customs compliance exposures if you are importer of record

If you sell DDP or otherwise control U.S. entry:

  • classification, origin, and valuation disputes can create probable-and-estimable assessments (ASC 450-20),
  • and can also trigger disclosures under ASC 275 (risks and uncertainties) if outcomes could materially change estimates.

C. Transfer pricing (IRC § 482) — the central tax issue for exporters with U.S. affiliates

Where your U.S. customer is a related-party distributor/importer, tariffs in 2025–2026 are fundamentally a profit allocation problem.

i) Legal anchor: IRC § 482

IRC § 482 authorizes the IRS to allocate income and deductions among controlled parties to prevent evasion and clearly reflect income and requires intangible returns to be commensurate with income where applicable.

In practice, many EU/UK/Ireland groups use a tested-party U.S. distributor under profit-based methods (e.g., CPM under Treas. Reg. § 1.482-5—method mechanics not re-cited here), and tariffs depress the U.S. importer’s margin.

Exporter consequence: to keep the U.S. entity within its arm’s-length range, groups often:

  • reduce intercompany sell-in prices,
  • grant tariff credits,
  • or revise risk allocation to share tariff costs.

ii) Customs valuation overlay (19 U.S.C. § 1401a) and the “tax vs customs” conflict

Customs duties are calculated on customs value under 19 U.S.C. § 1401a. When you adjust intercompany prices to manage tariff incidence, you are implicitly changing (or attempting to change) dutiable value and therefore duty.

This creates a structural conflict:

Tax authorities may accept (or even require) intercompany repricing to restore arm’s-length results.

Customs authorities scrutinize related-party pricing and may resist retroactive adjustments if not properly structured.

iii) IRC § 1059A: the rule that links customs value to U.S. tax inventory basis for related-party imports

For related-party imports, IRC § 1059A limits the amount of costs that can be included in a U.S. importer’s basis/inventory cost to the amount considered in computing customs value for those same costs.

Treasury regulation Treas. Reg. § 1.1059A-1 operationalizes this:

It states the general rule that basis/inventory cost may not exceed customs value for overlapping costs (subject to defined adjustment mechanisms). [44a]

It provides permitted adjustments (e.g., certain freight/insurance, post-importation services, other amounts properly included in inventory cost but not customs value) and requires offsets for rebates and reductions.

It binds the taxpayer to the “finally determined customs value” and other final determinations of Customs (classification/value finality matters greatly when you do year-end transfer pricing true ups).

Exporter consequence: you cannot treat transfer pricing as a “pure tax lever” without potentially breaking customs alignment or triggering § 1059A constraints at the U.S. importer.

iv) Post-import transfer price adjustments and refund mechanics (operational consequence)

If the EU/UK/Ireland exporter grants retroactive credits or adjusts prices after import, U.S. importers may need to correct entries and potentially file:

  • post-summary corrections or
  • protests under 19 U.S.C. § 1514 for liquidated entries.

From an exporter perspective, this matters because U.S. customers may demand you provide documentation, price adjustment support, and timeline cooperation—sometimes via contract covenants.


6) EU vs UK vs Ireland (exporter viewpoint): where the 2026 “hotspots” differ

Exporter location2025 tariff posture that shapes 2026 pricingMost common exporter-side accounting impactsMost common exporter-side tax impacts
Ireland (EU member)Covered by EU framework implementation; MFN-only carve-outs for certain aircraft/parts and generic pharma inputs; autos/parts modified toward 15% combined where eligibleCustomer rebate programs; contract disputes over tariff sharing; demand-driven inventory risk (Ireland entity inventory)Transfer pricing with U.S. affiliates importing Irish goods; customs-value alignment; potential need to revise intercompany agreements to allocate tariff risk
EU (non-UK)Initial reciprocal tariff volatility, then EU framework: MFN-only for specified categories; autos/parts modified toward 15% combined; metals remain structurally pressured under 232Greater risk of price concessions and volume loss in industrial categories; impairment indicators in metal/auto-adjacent asset groupsSame § 482 / customs / § 1059A alignment issues; increased origin/classification documentation burden
United Kingdom10% baseline on most goods; targeted sector relief (autos quota logic; metals more favourable than “global” in some structures); aerospace relief conceptsQuota allocation economics drive rebates/variable consideration; contract modifications and customer concentration riskIntercompany pricing updates to keep U.S. importer within arm’s-length range; avoid misalignment between TP and customs

7) What finance teams typically “lock down” in 2026 for an exporter group

A. Contract architecture (to avoid accidental ASC 450 problems)

Clear Incoterms and importer-of-record designation (avoid accidental DDP duty exposure). Explicit tariff pass-through / change-in-law clauses. Explicit treatment of tariff refunds (if tariffs are later invalidated): who benefits, and how quickly is value returned.

B. Pricing governance (to avoid variable consideration surprises)

Formal tariff surcharge policies (if used).

Controls for rebates/credits so they’re either:

  • clearly in ASC 606 variable consideration mechanics, or
  • clearly in ASC 450 loss contingency workflows (if disputed/claim-like).

C. Transfer pricing and customs integration (the “don’t let tax break customs” discipline)

Updated intercompany agreements specifying who bears tariff risk. A documented policy for intercompany price adjustments (timing, triggers, formulas).

Confirmation that any TP changes don’t create customs valuation contradictions or § 1059A problems at the U.S. importer.

D. Disclosures and subsequent events posture

Even absent a Supreme Court decision as of January 9, 2026, the tariff litigation status can drive:

  • ASC 275 risk and uncertainty disclosures (if material),
  • ASC 855 subsequent event monitoring (if a decision arrives before issuance),
  • and, for SEC registrants, risk factor / MD&A updates reflecting tariff and litigation volatility.
