Quick Answer

Customs clearance in the Republic of Ireland involves making sure that the imported or exported goods adhere to all the necessary customs regulations of the country prior to their clearance. This involves filing customs declaration forms, submitting the relevant documents, classification of the goods and payment of customs duty/import VAT on those goods.

What Is Customs Clearance?

Customs clearance is the process of declaring goods to customs authorities when they enter or leave the Republic of Ireland from countries outside the European Union.

The declaration provides customs with essential information about the shipment, including:

• The type of goods being transported
• The importer and exporter
• The customs value
• The country of origin
• The appropriate commodity code
• The customs procedure being used

The information is examined by Irish Customs in order to determine whether the cargo can be released or whether further scrutiny is needed.

While most of the declarations are done electronically, customs officials can ask for additional information and perform inspection when necessary. The guidance issued by Irish Revenue Commissioners outlines customs processes applicable to companies conducting business across borders.

When Businesses Need Customs Clearance 

Businesses generally need customs clearance whenever goods move between the Republic of Ireland and countries outside the European Union.

Common examples include imports from:

• Great Britain (England, Scotland and Wales)
• United States
• China
• Canada
• Australia
• Switzerland
• Other non-EU countries

Likewise, exports from the Republic of Ireland to these destinations usually require customs declarations before the goods can leave the country.

In case the company conducts its business transactions only inside the Single Market of the EU, there is no need for any customs declaration. Nonetheless, some other requirements like VAT return may still apply to some transactions.

If you're unsure which procedures apply to your shipments, Westmond's Customs Know-How hub provides practical guidance on customs regulations, commodity codes, rules of origin, Incoterms, and other topics businesses regularly encounter. 

Businesses That Require Customs Clearance 

It is not necessary that only big factories and multinational companies need customs clearing.

Many businesses require it, such as:

• Manufacturers importing raw materials
• Engineering firms purchasing specialist equipment
• Food and beverage suppliers
• Online retailers sourcing products overseas
• Pharmaceutical companies
• Construction suppliers
• Wholesale distributors
• Businesses exporting Irish products worldwide

Even organisations importing only a few consignments each month must ensure every shipment meets customs requirements before it reaches the border.

Importance of Accurate Customs Clearance 

Many businesses see customs clearance as paperwork that simply needs to be completed before goods arrive.

In reality, accurate customs declarations play a vital role in keeping supply chains running smoothly.

Well-prepared customs documentation helps businesses:

• Reduce border delays
• Avoid unnecessary storage charges
• Ensure customs duties are calculated correctly
• Maintain compliance with Irish and EU regulations
• Minimise the risk of customs queries
• Improve delivery reliability for customers

On the other hand, incomplete or inaccurate declarations can result in shipments being held while additional information is requested.

For businesses operating on tight production schedules or supplying time-sensitive orders, these delays can have a significant commercial impact.

The Role of an EORI Number in International Trade

One of the first requirements for businesses trading internationally is obtaining an Economic Operators Registration and Identification (EORI) number.

An EORI number identifies your business when dealing with customs authorities across the European Union.

In most cases, businesses importing or exporting goods outside the EU will require an EORI number before customs declarations can be completed.

Applying for an EORI number is usually straightforward, but it's important to arrange this before your first international shipment rather than waiting until goods are ready to move.

How Does the Customs Clearance Process Work?

Although every shipment is different, customs clearance generally follows the same sequence.

1. Gather Shipment Information

The procedure is initiated prior to the movement of the merchandise from the supplier.

Shipping documentation should ideally consist of:

• Product description
• Quantity
• Dollar value
• Country of origin
• Weight
• Packaging specifications
• Commodity codes

Full disclosure will minimise problems later on.

2. Prepare the Required Documentation

Supporting documents form the foundation of every customs declaration.

Depending on the shipment, these may include:

Certain products, including food, plants, chemicals, or controlled goods, may require additional documentation before customs clearance can be completed.

3. Submit the Customs Declaration

Once the documentation has been prepared, the customs declaration is submitted electronically.

The following information must be provided in the declaration:

• Importer and exporter information
• Commodity codes
• Customs value
• Goods' country of origin
• Customs process
• Transportation information

Irish Customs will use the above information to evaluate the shipment for possible customs duties, VAT, etc.

4. Customs Review and Risk Assessment

Once the declaration has been filed, then the custom officers will go through it in an electronic format.

Many shipments go through this process without a hitch.

Other consignments can be flagged for document examination or physical inspection as part of the normal process of risk management by the customs.

This is not always a sign that there is something wrong with your shipment. The reasons for conducting customs examinations can vary.

Understanding Commodity Codes

All goods entering or leaving the Republic of Ireland have to be assigned a commodity code, which is also known as an HS Code.

Commodity codes determine:

• Customs duty rates
• Import VAT treatment
• Licensing requirements
• Product restrictions
• Eligibility under trade agreements

Although two products may appear similar, they can sometimes fall under different commodity classifications, resulting in different customs duty rates.

Using the wrong commodity code can lead to:

• Incorrect duty calculations
• Customs queries
• Delayed shipments
• Additional administration
• Financial penalties

Businesses uncertain about product classification can also use the European Commission's Access2Markets portal to research tariff information and trade requirements.

Customs Duties and Import VAT

When goods enter the Republic of Ireland from outside the European Union, customs authorities may charge customs duty and import VAT.

The amount payable depends on several factors, including:

• The commodity code
• The customs value of the goods
• The country of origin
• Whether a trade agreement applies

Where goods qualify under a preferential trade agreement, businesses may benefit from reduced or zero customs duty, provided they can demonstrate that the relevant rules of origin have been met.

Understanding these requirements before goods are dispatched helps businesses estimate import costs more accurately and avoid unexpected charges.

Common Customs Clearance Mistakes Businesses Make

Even experienced importers and exporters can encounter customs issues if shipment information is incomplete or inaccurate. While customs regulations are detailed, many delays are caused by avoidable administrative errors rather than complex legal requirements.

Here are some of the most common mistakes businesses make.

Using the Wrong Commodity Code

Every product must be classified correctly using a commodity code. These codes determine customs duty rates, import restrictions, licensing requirements, and whether a product qualifies for preferential treatment under a trade agreement.

Using an incorrect code can result in the wrong amount of duty being paid, customs queries, or delays during shipment review.

Providing Incomplete Commercial Invoices

The commercial invoice must have all the relevant information regarding the products, which includes product description, value, quantity, origin of goods, along with the buyer and seller details.

In case of any missing information, the Irish Customs may ask for more documentation before allowing the shipment.

Declaring the Wrong Customs Value

Customs value is important for calculating duties and import VAT. Any error in declaring the value may result in extra charges, amendments to declaration, or other compliance problems.

Invoices must state the details of the transaction as well as all the information needed for valuing the goods for customs purposes.

Missing Supporting Documentation

Some goods require more than a commercial invoice and packing list.

Depending on the products being imported, customs may also require:

• Certificates of origin
• Import licences
• Health certificates
• Phytosanitary certificates
• Safety documentation

Preparing these documents before goods are dispatched helps prevent unnecessary delays at the border.

Waiting Until the Shipment Has Left

One of the biggest mistakes businesses make is treating customs as something to deal with once the goods are already in transit.

Reviewing documentation before the shipment leaves gives time to identify missing information, correct errors, and ensure declarations can be submitted without unnecessary pressure.

Why Can Shipments Be Delayed at Customs?

Although many consignments are cleared quickly, customs authorities may hold goods for routine checks or to request additional information.

Common reasons for delays include:

• Incorrect or incomplete customs declarations
• Missing commercial invoices or supporting documents
• Incorrect commodity codes
• Customs inspections
• Outstanding customs duty or import VAT
• Regulated goods requiring additional approvals

Preparing accurate customs documentation before the shipment begins its journey is one of the most effective ways to minimise delays.

Practical Tips for Smoother Customs Clearance

Good preparation can make a significant difference to the speed and efficiency of customs clearance.

Businesses can improve the process by following a few simple best practices.

Prepare Documentation Early

Gather invoices, packing lists, transport documents, and any supporting certificates before goods leave the supplier.

Early preparation allows time to correct any missing or inaccurate information.

Keep Shipment Information Consistent

The details provided on the commercial invoice, packing list, transport documents, and customs declaration should match.

Differences between documents often prompt customs to request clarification.

Review Commodity Codes Regularly

If your business imports a wide range of products or introduces new product lines, it's worth reviewing commodity classifications periodically to ensure they remain accurate.

Understand the Rules of Origin

Trade agreements can reduce or eliminate customs duty on qualifying goods, but businesses must be able to demonstrate that products meet the relevant rules of origin.

The European Commission's Access2Markets portal guides rules of origin, tariffs, and trade requirements for businesses trading internationally.

Keep Accurate Records

Maintaining organised customs records makes it easier to answer any future customs queries and supports ongoing compliance with customs regulations.

Customs Clearance and Freight Forwarding: What's the Difference?

Even though these two are used interchangeably, it is important to understand that they are actually two different functions.

Freight forwarding deals with the arrangement of transport for shipment of goods from one place to another. It may include organizing transport through land, water, or air modes of transport, scheduling ships, etc.

Customs clearance is concerned with the process of meeting legal requirements for international commerce. It involves the preparation of customs documents, accurate documentation, etc.

For many businesses, these services work hand in hand.

A shipment may be transported efficiently, but it cannot continue its journey until customs requirements have been satisfied. Likewise, accurate customs declarations are only part of the process if transport arrangements have not been properly coordinated.

By combining customs expertise with freight forwarding, businesses benefit from a more streamlined supply chain with fewer administrative challenges.
