US Tariffs and Irish Exporters: What Dundalk SMEs Need to Know in 2026

In the first months of 2026, Irish businesses with US market exposure have been dealing with a level of trade policy uncertainty not seen since Brexit. The tariff measures announced and implemented by the US administration in 2025 have created real disruption for Irish exporters and for the Irish subsidiaries and supply chains of US multinationals operating here.

In my role as PRO of Dundalk Chamber, I have been following this closely through our engagement with Chambers Ireland and through the Irish Government’s response programme. In March 2026, Chartered Accountants Ireland welcomed the Government’s publication of its Action Plan to Support Market Diversification — a plan with over 100 actions designed to help Irish businesses facing the trading challenges posed by US tariffs.

This article is my plain-English take on what the tariff situation means for Irish SMEs, where the exposure lies, and what actions are genuinely available.

The Context: What Changed and When

The US tariff measures that took effect during 2025 imposed broad-based additional tariffs on imports from a range of countries, including Ireland. The specific rates and product coverage have shifted several times, creating considerable uncertainty for businesses trying to plan.

For Irish businesses, the most significant exposure falls into two categories.

First, Irish businesses that directly export goods to the US market face higher tariff costs on those goods at the US border. The tariff is paid by the US importer — typically the US buyer or the US subsidiary — but the economic effect is to make Irish goods more expensive in the US market relative to domestically produced alternatives or goods from countries with more favourable trade access.

Second, Irish businesses in the supply chains of US multinationals operating in Ireland face indirect exposure if their US parent companies are cutting costs, restructuring, or reducing Irish operations in response to the broader trade environment.

The Irish agri-food sector — worth a record €19 billion in exports in 2024 — has particular exposure given the volume of food and drink exports to the US and the sector’s concentration in certain product categories.

Which Sectors Have Most Exposure?

Agri-food and beverages. Irish whiskey, dairy products, prepared foods, and specialist food products have established US market positions that are now under pressure. Small artisan producers and medium-sized food businesses that have invested in building US distribution are facing a direct cost impact.

Pharmaceuticals and medical devices. Ireland is one of the world’s largest exporters of pharmaceuticals, and the US is the primary destination for much of that output. The larger multinational pharmaceutical exporters have the resources to manage tariff impacts through pricing, supply chain restructuring, and regulatory engagement. Smaller indigenous businesses in the life sciences supply chain are more exposed.

Technology and professional services. Software and services exported from Ireland to the US are generally less directly affected by goods tariffs — tariffs apply to goods, not to cross-border services. However, the broader trade tension creates uncertainty in US capital markets and corporate spending, which has indirect effects on demand for Irish technology products and services.

Manufacturing. Irish manufacturers exporting finished goods to the US face direct tariff impact on the product value. The competitive dynamics depend heavily on whether comparable products from competing countries face similar or different tariffs.

What the Government’s Action Plan Contains

Chartered Accountants Ireland welcomed the Government’s Action Plan to Support Market Diversification. The plan has over 100 actions, reflecting the scale of the challenge.

The core themes include:

Market diversification support — helping Irish businesses that are heavily dependent on the US market to develop alternative export markets in the EU, the UK, the Middle East, and Asia-Pacific. Enterprise Ireland, the IDA, and Bord Bia all have enhanced programmes for this purpose.

Financial support — additional funding through Enterprise Ireland for businesses directly affected by tariff costs, to help with the cost of market development, product adaptation for new markets, and business continuity planning.

Regulatory and trade engagement — the Irish Government working through EU channels to negotiate with the US administration, and direct ministerial engagement with US counterparts on the impact on bilateral economic relations.

Access to advice — enhanced access to trade specialists and advisors through Enterprise Ireland and the network of LEOs, to help individual businesses assess their exposure and develop mitigation strategies.

What SMEs Should Actually Do

For most Dundalk SMEs, the direct impact of US tariffs is limited — the majority of small businesses in County Louth do not have significant US export exposure. For those businesses, the domestic tax measures in Budget 2026 are likely to be more immediately relevant. But the indirect effects — through the spending decisions of US multinationals operating in Ireland, through the general economic uncertainty, and through the potential knock-on effects on Irish economic growth — are real.

For businesses with direct US exposure, the practical actions are:

Quantify your exposure now. What proportion of your revenue comes from US customers, directly or through US-owned customers in Ireland? What is the tariff cost on your specific products, and who bears it under your current customer contracts? If you export goods, ensure you also understand the VAT implications of cross-border sales, as zero-rating rules apply differently depending on destination.

Review your pricing and contract terms. Are your current customer contracts fixed price, or do they allow for tariff cost pass-through? Can you renegotiate terms that make the tariff impact sharing more equitable?

Assess market diversification options. Enterprise Ireland’s market diversification support is specifically designed for this moment. If you have been planning to expand into other export markets and US tariffs have accelerated that timeline, Enterprise Ireland is the right first call.

Don’t assume the worst. Trade policy can change quickly. The tariff measures that are live today may be modified, suspended, or reversed. Building a permanent strategic shift on a temporary policy change is its own risk. Scenario planning for multiple outcomes is more valuable than a single-line response.

For businesses without direct US exposure but operating in the broader export economy, the message is to monitor the situation, stay close to your sector association and Chamber connections for updates, and ensure that your business planning has scenario flexibility built in.

The trading environment in 2026 rewards businesses that are agile and well-informed. The Chamber and Chambers Ireland are actively tracking developments and providing updates to members. For more on trade, tax, and planning topics for Irish SMEs, explore our taxation guides.
