Top 5 Customs Compliance Challenges in Ireland (and How to Solve Them)

Do you know why Irish import/export businesses face so many challenges in customs compliance, even years after Brexit?
Since the UK departed from the EU, Ireland has been uniquely affected. As the only EU country sharing a land border with the UK, Irish firms rely heavily on trade routes through Great Britain and Northern Ireland.
New rules, extra paperwork, and shifting regulatory standards have made compliance more complex than ever. Below, I’ll highlight the major customs compliance challenges in Ireland and possible solutions.
5 customs compliance challenges & solutions in Ireland
Here are the common customs compliance challenges in Ireland and how they can be solved:
1. Electronic declarations and system integration
The challenge
Ireland has implemented the Automated Import System (AIS) and Automated Export System (AES) to replace previous systems for handling imports and exports from non-EU countries. AIS and AES handle validation, customs declarations, and other formalities.
All declarations must now be submitted electronically. The system requires businesses (or their agents) to use customs software that interfaces correctly with AIS and AES. If not, declarations are rejected, delayed, or incorrect.
Failures here cause delays, extra costs, and possibly penalties. Equipment or software mismatches, staff unfamiliarity, or late/missing declarations create bottlenecks.
How to solve
Invest in proper customs software or ensure your agent has it. Make sure it is tested for AIS and AES compatibility.
Try iCustoms iAIS/iAES, which is integrated with Ireland’s system, and ensure compliance.
2. Safety & security and pre-arrival declarations (ENS / ICS2)
The challenge
All goods entering Ireland from GB (or non-EU countries) require Safety & Security (S & S) declarations such as Entry Summary Declarations (ENS) via the Import Control System 2 (ICS2). These must precede dispatch (departure) from the origin.
The EU has introduced ICS2, which further strengthens requirements for pre-arrival security data. Irish businesses must keep up with phased roll-outs, different deadlines depending on transport mode (air, sea, road, RoRo), etc.
If the ICS2 data is late, wrong or incomplete, the shipment can be held up at the border, leading to delays or extra fees.
How to solve it:
Use an automated tool to submit ICS2 declarations, such as iCustoms ICS2, which eliminates manual work, automates document processing, form filling, validating, and submitting.
3. Classification, tariff, and rules of origin
The challenge
Determining the correct HS code classification under the EU customs system can be subtle; small differences in material composition or function of goods lead to different classification codes and thus different duties or requirements.
Other than this, rules of origin have also become very critical: to benefit from preferential tariff treatment under the EU-UK Trade and Cooperation Agreement, goods (or inputs) must meet certain origin thresholds. If not, duties apply.
Many businesses sourcing components from non-EU countries that are re-exporting to the UK are caught unprepared.
Incorrect classification or origin can cause sudden cost increases, damage to reputation, and cash flow disruption.
How to solve it:
Use an AI-powered tool for classifying goods and finding accurate HS codes; iCustoms offers one such tool, i.e., iClassification.
4. Paperwork completeness and accuracy
The challenge
Many delays or compliance failings stem simply from missing, incomplete or inaccurate paperwork; this includes customs declarations, licence or permit documents (for restricted or controlled goods), safety/security forms, etc.
Since Brexit, certain goods now need additional health, phytosanitary, or regulatory certifications when moving between Ireland, the UK, or other countries. Many small or medium businesses are still adapting.
Manual extraction and input of data from documents to customs forms leads to mismatches and errors.
It causes delays, retention of shipments at borders, spoilage, and penalties. Also, there is audit risk when data doesn’t match or when documentation is not kept properly.
How to solve it:
Use document automation tools such as iCustoms IDP that automatically extract data, validate and fill in customs forms, saving time and ensuring accuracy.
5. Costs, delays and unpredictability
The challenge
The collective effect of duties, tariffs (if rules of origin not met), customs agent fees, software or compliance investment, plus potential demurrage or storage costs from delays, all raise the cost base.
Delays are especially problematic for just-in-time supply chains or perishable goods, where additional time in transit or under customs control can reduce product quality or spoil goods.
Regulatory changes, changing UK import rules, evolving EU enforcement or new controls (e.g., sanitary, labelling, etc.) make it hard to plan.
It has a negative impact on profit margins, cash flow, and customer satisfaction. Businesses may be exposed to unexpected costs.
How to solve it:
Rely on AI-powered tools for document processing, data extraction and mapping, validation, and declaration submission. iCustoms offers such tools that automate the process from start to finish.
Wrapping up
Customs compliance in Ireland continues to challenge businesses due to post-Brexit changes, AIS/AES requirements, ICS2 pre-arrival rules, and stricter paperwork checks. Errors in HS code classification, rules of origin, or incomplete documents can quickly lead to penalties, shipment delays, and rising costs.
The most effective way forward is to adopt digital tools that handle classification, automate document processing, and integrate directly with Irish systems like AIS, AES, and ICS2.
With platforms such as iCustoms, companies can streamline compliance, improve accuracy, and maintain supply chain reliability.
