Customs Law in Poland: Complete 2026 Guide for Importers and Exporters

Executive Summary

Poland applies the EU Union Customs Code and the EU Common Customs Tariff, supplemented by Polish customs and tax rules. For most businesses importing into Poland in 2026, the most important questions are the correct CN/TARIC classification, customs value and origin, the method of financing import VAT, CBAM exposure and the quality of data supplied to customs systems.

Customs Law in Poland — What Changes in 2026

For importers, 2026 is not a routine customs year. Several EU reforms directly affect landed cost and border compliance.

What’s new in 2026?

1. The €150 customs-duty exemption ended on 1 July 2026.
Low-value parcels are no longer automatically duty-free. A temporary €3 customs duty applies under the transitional EU regime for qualifying consignments. (Taxation and Customs Union)

2. A new EU handling fee is coming.
The March 2026 political agreement on the EU customs reform provides for an EU-wide handling fee on small distance-selling consignments. Member States must apply it no later than 1 November 2026. (Consilium)

3. CBAM entered its definitive period on 1 January 2026.
Companies importing covered goods must now monitor not only customs classification and value but also carbon-related regulatory exposure. (Taxation and Customs Union)

4. EU customs reform reached a major political agreement on 26 March 2026.
The reform introduces an EU Customs Authority, an EU Customs Data Hub, new e-commerce rules and expanded simplifications for trusted operators. The Data Hub is scheduled to become operational for e-commerce goods on 1 July 2028. (Consilium)

For CFOs, these developments should be treated as a pricing and working-capital issue, not merely a logistics update.

The Legal Framework: EU and Polish Customs Rules

Polish customs law operates primarily within the harmonised EU customs system.

The core legislation is Regulation (EU) No 952/2013 establishing the Union Customs Code (UCC). It is supplemented by the UCC Delegated Regulation and Implementing Regulation, as well as tariff, origin, trade defence and product-specific legislation. (Eur-Lex)

Polish legislation supplements the EU framework in areas such as national customs administration, procedures, sanctions and import VAT.

This means that Poland does not set an independent customs tariff for imports from China, the United States, the UK or Turkey. It applies the EU Common Customs Tariff.

Harmonisation does not, however, make every practical customs experience identical across the EU. National customs administrations remain responsible for controls, risk analysis and enforcement. Differences in operational practice can therefore affect clearance times and documentation expectations.

Who Enforces Customs Law in Poland? The Role of KAS

Customs matters in Poland are administered by the National Revenue Administration — Krajowa Administracja Skarbowa (KAS) and its customs and tax authorities.

Their functions include:

• accepting and verifying customs declarations,

• examining goods and documents,

• collecting customs duties and import taxes,

• performing post-clearance controls,

• enforcing tariff classification, origin and valuation rules,

• administering customs authorisations,

• cooperating in EU-level risk management.

Businesses can also seek binding decisions on matters such as tariff classification through Binding Tariff Information (BTI/WIT).

Customs controls increasingly cover non-fiscal regulatory obligations as well.

CBAM illustrates this shift. From 2026, customs data is used to monitor whether imports fall within CBAM rules and whether the importer or indirect customs representative meets applicable authorisation requirements. The CBAM framework also provides for monitoring of the annual mass-based threshold. (Eur-Lex)

Customs has therefore become a gateway for environmental and product-compliance enforcement, not merely duty collection.

Customs Procedures in Poland: Which One Applies to You

Choosing the customs procedure determines when customs duty and import VAT become payable and whether a guarantee may be required.

Release for free circulation

This is the standard procedure when non-EU goods are imported permanently into Poland. Customs duty becomes due and import VAT must be accounted for.

Export

Export removes Union goods from the EU customs territory. For Polish VAT purposes, zero-rating depends on meeting the statutory requirements and holding appropriate evidence.

See our guide to export confirmation documents.

External transit — T1

T1 allows non-Union goods to move under customs supervision without immediately paying import duties at the first EU border.

Customs warehousing

Warehousing can postpone duty and import VAT until goods are released for free circulation or placed under another procedure.

Inward processing

Useful where non-EU goods are imported for manufacture, processing or repair and subsequently re-exported or otherwise discharged under the authorised procedure.

Temporary admission

Designed for goods entering the EU temporarily, such as professional equipment, exhibition goods or certain machinery.

Cross-border supply chains may also use customs procedure 4200 where the legal conditions for import followed by an intra-Community supply are satisfied.

How to Submit a Customs Declaration in Poland (PUESC)

Poland operates electronic customs services through PUESC — Platforma Usług Elektronicznych Skarbowo-Celnych.

PUESC lists systems including AIS/IMPORT PLUS, AIS/CCI, AIS/e-COMMERCE, AES/ECS2 PLUS and NCTS2 PLUS for different customs processes. (puesc.gov.pl)

A customs declaration normally requires information including:

• the importer’s EORI number,

• declarant or representative details,

• CN/TARIC classification,

• customs procedure,

• country of origin,

• customs value,

• quantity and weight,

• commercial invoice data,

• freight information,

• applicable licences or certificates,

• supporting documents.

A business involved in customs operations should obtain an EORI before its first relevant transaction. See our EORI number registration service.

ICS2: data quality has become a customs issue

The EU’s Import Control System 2 relies on advance cargo information for security and risk analysis. The system is designed around richer, earlier and more consistent supply-chain data. (Eur-Lex)

Importers should therefore audit whether their ERP, marketplace and logistics data contains consistent:

• HS/CN codes,

• product descriptions,

• origin information,

• consignor details,

• identification numbers where required,

• values,

• transport information.

Descriptions such as “parts”, “samples”, “accessories” or “goods” may be commercially convenient but can be inadequate for effective customs risk analysis.

The practical lesson is simple: customs data quality should be treated as master-data governance, not as a freight forwarder’s clerical task.

Import Duties and Import VAT in Poland

This is where customs decisions become finance decisions.

A classification error can change the duty rate. An origin error can eliminate a tariff preference. An inefficient import VAT structure can lock substantial cash at the border.

How Customs Duty Is Calculated

Customs duty generally depends on three variables:

1. Tariff classification
Each product must be classified under the Combined Nomenclature and TARIC.

2. Origin
Origin determines whether preferential tariff treatment, trade restrictions or trade defence measures apply.

3. Customs value
The transaction value is normally the starting point, subject to UCC valuation rules and required additions such as certain freight and insurance costs up to the relevant EU entry point.

The simplified formula is:

Customs duty = customs value × applicable tariff rate

There is no single “Polish customs duty rate”. Poland uses the EU tariff, and the rate can range from zero to significant percentages depending on the product and origin.

Import VAT and the Cash-Flow Problem

The standard Polish VAT rate is 23%.

The import VAT taxable amount generally starts with customs value and is increased by customs duties and specified incidental costs under Polish VAT rules.

For an importer paying VAT at clearance, this can create a major working-capital requirement even when the VAT will ultimately be deductible.

Polish article 33a of the VAT Act can remove this financing problem.

An active Polish VAT taxpayer meeting the statutory conditions can account for import VAT in its VAT return for the period in which the import tax obligation arose instead of paying that amount as a cash liability at the border.

Relevant compliance requirements include, depending on the import structure:

• active Polish VAT registration,

• evidence or statements relating to tax and social-security arrears within statutory limits,

• correct customs representation,

• timely VAT reporting,

• correct customs and tax documentation.

Importantly, AEO status is not a universal statutory prerequisite for article 33a. Specific customs arrangements, including certain centralised clearance structures, may create additional requirements, but article 33a should not be presented as an “AEO-only” mechanism.

Read our detailed comparison of deferred import VAT under article 33a.

Foreign businesses should also determine whether they need VAT registration in Poland before structuring imports.

Example: €100,000 of goods, 6% duty

Assume:

• invoice value: €100,000

• freight included in customs value: €4,000

• customs duty rate: 6%

• import VAT rate: 23%

Customs value:
€100,000 + €4,000 = €104,000

Customs duty:
€104,000 × 6% = €6,240

Simplified import VAT base:
€104,000 + €6,240 = €110,240

Import VAT:
€110,240 × 23% = €25,355.20

The importer therefore faces:

• €6,240 customs duty, plus

• €25,355.20 import VAT.

Without article 33a, the VAT component may have to be financed before it is recovered through the VAT system.

With article 33a, assuming full entitlement to deduction and all conditions are satisfied, the €25,355.20 can generally be accounted for through the VAT return rather than funded at customs clearance.

For a company importing ten comparable shipments each month, this example represents more than €250,000 of monthly VAT financing that may potentially be removed from the border cash-flow cycle.

Preferential Origin and Trade Agreements

Preferential origin can reduce or eliminate customs duty where an applicable EU trade agreement provides preferential tariff treatment.

Depending on the agreement and transaction, evidence may include:

• EUR.1 movement certificates,

• statements or declarations on origin,

• registered or approved exporter mechanisms,

• other agreement-specific evidence.

Do not treat supplier statements as a substitute for origin due diligence.

If preferential origin is claimed incorrectly, customs authorities may retrospectively assess the duty that should have been paid. Contractual recovery from the supplier may then be commercially difficult.

The End of the €150 De Minimis Relief — What Changed on 1 July 2026

This is one of the most important EU customs changes for e-commerce businesses in 2026.

Until 30 June 2026, goods in consignments with an intrinsic value of no more than €150 generally benefited from customs-duty relief.

That changed on 1 July 2026.

The EU introduced a temporary flat customs duty of €3 for each distinct tariff category of goods contained in qualifying low-value parcels sent directly to EU consumers. The transitional mechanism is due to run until 1 July 2028. (Taxation and Customs Union)

This distinction matters.

A parcel containing several identical products classified under the same relevant tariff subheading does not necessarily generate €3 for every physical unit.

For example, the Council explains that a parcel containing one silk blouse and two wool blouses represents two tariff categories and therefore attracts €6, not €9, under the temporary mechanism. (Consilium)

The wider e-commerce reform

The March 2026 EU customs reform agreement goes further.

It provides that platforms and distance sellers sending goods into the EU will be treated as importers responsible for customs formalities and payments rather than leaving those obligations with the EU consumer.

An EU-wide handling fee will also apply to small distance-selling consignments. The final amount is to be fixed by Commission delegated act, and Member States must begin applying the fee no later than 1 November 2026.

The EU Customs Data Hub is scheduled to become operational for e-commerce goods on 1 July 2028. (Consilium)

What importers should do now

1. Recalculate landed cost per parcel.
Models based on historical duty-free treatment below €150 are obsolete.

2. Reconsider direct-to-consumer fulfilment.
Compare parcel-by-parcel imports with bulk import into an EU warehouse followed by domestic/EU fulfilment.

3. Review IOSS architecture.
Map the seller, marketplace, importer, IOSS intermediary and customs declarant responsibilities.

4. Audit tariff data.
Because the temporary €3 mechanism operates by tariff category, poor HS/CN classification can now affect both compliance and unit economics.

For VAT aspects, see our guide to IOSS for low-value consignments.

CBAM: The New Customs Obligation for Importers of Steel, Aluminium and Cement

The definitive CBAM regime has applied since 1 January 2026. (Taxation and Customs Union)

CBAM covers specified goods in sectors including:

• iron and steel,

• aluminium,

• cement,

• fertilisers,

• hydrogen,

• electricity.

A major simplification introduced in 2025 replaced the previous €150 CBAM consignment exemption with a single annual mass-based threshold.

The initial threshold is 50 tonnes net mass per importer per calendar year, applied cumulatively to covered goods in the four mass-based sectors of iron and steel, aluminium, fertilisers and cement. (Eur-Lex)

Hydrogen and electricity are not covered by this mass-based exemption in the same way.

What happens if the importer exceeds 50 tonnes?

Once the importer exceeds the threshold within the calendar year, the CBAM obligations apply to the relevant imports for that year, including the requirement to hold the appropriate authorised CBAM declarant status and account for embedded emissions. (Eur-Lex)

This means that threshold monitoring should not be done only at year-end.

Procurement and customs systems should track cumulative CBAM tonnage continuously.

2026 imports create a 2027 cash obligation

The first annual CBAM declaration covering 2026 imports must be submitted by 30 September 2027.

The corresponding certificates must also be surrendered by that date.

Member States begin selling CBAM certificates from 1 February 2027. (Eur-Lex)

The implication for finance teams is important:

A 2026 import can create a CBAM cost economically attributable to 2026 even though the related certificate cash outflow occurs in 2027.

Companies should therefore consider CBAM in:

• product pricing,

• supplier negotiations,

• margin calculations,

• provisions/accrual analysis,

• purchasing decisions,

• contract clauses concerning emissions data.

Can a customs agent take responsibility for CBAM?

An authorised CBAM declarant may delegate the submission of its CBAM declaration to another person acting in its name.

However, the authorised CBAM declarant remains responsible for compliance.

An indirect customs representative assuming the CBAM role faces specific regulatory obligations of its own.

Using a customs agency therefore does not automatically transfer every CBAM risk away from the importer.

That point should be addressed expressly in customs representation agreements.

Customs Controls, Risk Analysis and Inspections in Poland

Customs declarations can be cleared without physical inspection or selected for documentary or physical controls based on risk analysis.

Operationally, businesses often refer to:

• green channel — release without additional intervention,

• documentary/yellow control — verification of documents or data,

• red/physical control — examination of goods.

Risk factors may include:

• unusual customs values,

• inconsistent product descriptions,

• sensitive tariff headings,

• origin risk,

• new or irregular import patterns,

• trade defence measures,

• licensing requirements,

• previous compliance issues,

• security and safety information.

There is no reliable universal number of hours or days for a red-channel inspection.

Timing depends on the nature of the control, port or terminal, availability of documents, sampling requirements and whether other authorities must intervene.

For a CFO, the important point is therefore not an artificial “average clearance time” but the exposure to:

• demurrage,

• detention,

• terminal storage,

• warehouse charges,

• container utilisation costs,

• manufacturing downtime,

• missed delivery penalties.

These indirect costs can materially exceed the customs duty under dispute.

AEO Status and Customs Simplifications: Are They Worth It?

Authorised Economic Operator (AEO) status is an EU customs authorisation for businesses meeting specified compliance, record-keeping, solvency and — depending on the authorisation — professional competence or security criteria.

Article 39 UCC sets out the principal eligibility requirements. (Eur-Lex)

Potential benefits include:

• easier access to certain customs simplifications,

• reduced guarantees in appropriate circumstances,

• fewer controls,

• priority treatment if selected for control,

• improved cooperation with customs authorities,

• recognition in international AEO programmes where arrangements exist.

When does AEO pay for itself?

There is no defensible rule such as “AEO becomes profitable at 500 declarations per year”.

The return depends on:

Volume.
More declarations create more opportunities to save administrative time.

Guarantees.
Businesses with significant customs guarantee requirements may derive greater financial benefit.

Control frequency.
A reduction in disruption can matter more than declaration fees.

Supply-chain criticality.
A manufacturer whose production line stops when components are delayed may value predictability more highly than an importer holding six months of stock.

Internal readiness.
A company with clean procedures and documented controls faces a lower implementation burden than a business that first needs to redesign customs governance.

The European Commission requires an AEO applicant to complete a detailed self-assessment process, and applicants must have an EORI number. (Taxation and Customs Union)

AEO should therefore be evaluated through a business case, not pursued as a badge.

Also note that AEO and article 33a import VAT accounting are separate concepts. AEO may support a broader customs-simplification strategy, but it is not universally required to use article 33a.

Customs Guarantees and Deferred Payment

Customs guarantees protect potential or existing customs debts.

Depending on the procedure, businesses may use:

• a bank or insurance guarantee,

• a cash deposit,

• a comprehensive guarantee covering multiple operations.

Guarantees are particularly relevant to procedures where customs duty is suspended, including transit, warehousing and processing.

The UCC also permits deferred payment arrangements for customs debts. Where payment is guaranteed, multiple customs debts arising over an authorised period can in certain circumstances be aggregated, with the period not exceeding 31 days. (Eur-Lex)

The finance question is whether the cost of:

• bank guarantee limits,

• guarantee premiums,

• collateral,

• administrative effort

is lower than the working-capital benefit created by the customs arrangement.

For high-volume importers, guarantee optimisation should therefore form part of treasury management.

Post-Clearance Audits and Penalties for Customs Violations

Release of goods does not mean the customs position is final.

Customs authorities can perform post-release controls and challenge issues such as:

• CN classification,

• customs value,

• origin,

• preferential treatment,

• customs procedure,

• licences,

• declared quantities,

• representation.

How far back can customs go?

A blanket statement that customs can always reassess imports for five years is inaccurate.

Under article 103 UCC, the standard limitation period for notifying a customs debt is three years from the date the debt was incurred.

Where the customs debt resulted from an act that could give rise to criminal court proceedings, the period is extended under national law to at least five and no more than ten years.

Separate tax, record-retention and fiscal-penal limitation rules may also apply.

Importers should therefore maintain records according to the longest period relevant to their customs and tax exposure rather than deleting documentation immediately after the normal three-year customs period.

Financial consequences

An error can lead to:

• retrospective customs duty,

• import VAT consequences,

• interest,

• loss of preferential treatment,

• administrative measures,

• suspension or revocation of customs authorisations,

• fiscal-penal exposure under Polish law where statutory conditions are met.

The UCC requires Member States to provide effective, proportionate and dissuasive penalties for breaches of customs legislation.

For material imports, a post-entry customs review can therefore function like a tax audit readiness exercise.

Compliance Checklist for Importing into Poland in 2026

Before importing goods into Poland, review the following:

• EORI: confirm that the importer has a valid EORI number.

• Importer of record: establish who legally acts as importer.

• CN/TARIC classification: validate tariff codes for material product lines.

• Customs value: review invoice price, assists, royalties, freight, insurance and related-party adjustments.

• Origin: distinguish non-preferential origin from preferential origin.

• Proof of preference: verify that certificates or origin statements are valid.

• Trade measures: check anti-dumping duties, quotas, restrictions and licences.

• CBAM: monitor whether annual imports approach the 50-tonne mass threshold in relevant sectors.

• Low-value parcels: recalculate landed cost under the rules applying from 1 July 2026.

• ICS2/master data: review product descriptions, HS data, origin and party identifiers.

• Import VAT: assess whether article 33a can improve working capital.

• Representation: determine whether customs representation is direct or indirect and understand liability.

• Guarantees: assess whether customs guarantees consume unnecessary credit capacity.

• Documentation: maintain a defensible customs audit file.

• AEO: quantify the business case rather than applying automatically.

• Post-entry review: periodically test previous declarations before customs authorities do.

FAQ

What is the customs duty rate in Poland?

Poland uses the EU Common Customs Tariff rather than setting separate Polish import duty rates. The rate depends primarily on the product’s CN/TARIC classification and its customs origin. Some goods are duty-free, while others attract material tariffs or trade-defence duties. The rate should be checked in TARIC before shipment.

Do I need an EORI number to import into Poland?

Businesses conducting customs operations in the EU generally need an EORI number. It should be obtained before the first customs operation requiring it. The number identifies the economic operator across EU customs systems. Foreign companies can obtain support with EORI number registration.

What is the import VAT rate in Poland?

The standard Polish VAT rate is 23%, although reduced rates can apply to particular goods. Import VAT is calculated on a taxable amount based on customs value plus customs duties and certain additional costs. The applicable VAT classification should therefore be checked separately from the customs tariff classification.

Can I defer import VAT in Poland?

Yes. Article 33a of the Polish VAT Act allows qualifying active VAT taxpayers to account for import VAT in their VAT return instead of financing it at customs clearance. Statutory conditions and documentation requirements apply. See our guide to deferred import VAT under article 33a.

What changed for low-value parcels in the EU from 1 July 2026?

The customs-duty exemption for consignments up to €150 ended. A temporary €3 customs duty now applies per distinct tariff category in qualifying low-value parcels under the transitional regime. An additional EU-wide handling fee is also due to apply no later than 1 November 2026. (Taxation and Customs Union)

Does CBAM apply to my imports?

It depends on the CN code, sector and annual volume. For iron and steel, aluminium, fertilisers and cement, the principal exemption is based on a cumulative 50-tonne annual threshold per importer. Hydrogen and electricity are treated differently. Companies should monitor quantities before the threshold is exceeded. (Eur-Lex)

How long can Polish customs audit my past imports?

There is no universal five-year rule. Under article 103 UCC, the normal period for notifying a customs debt is three years. If the debt results from conduct capable of giving rise to criminal proceedings, national law can extend the period to between five and ten years.

Is AEO status mandatory in Poland?

No. AEO is voluntary. It can provide significant benefits for businesses using customs simplifications, guarantees and high-volume supply chains, but the return depends on the importer’s actual operating model. AEO status is also not a universal prerequisite for accounting for import VAT under article 33a.

How We Support Importers and Exporters in Poland

Customs problems often become tax problems only after goods have already crossed the border.

We help international businesses structure the process before that happens.

Our support can include:

• Polish VAT registration,

• EORI registration,

• fiscal representative in Poland,

• analysis and implementation of article 33a import VAT accounting,

• customs and import VAT process reviews,

• CBAM exposure assessments,

• customs classification and origin risk reviews,

• preparation for post-clearance audits,

• review of import documentation and representation models,

• landed-cost and customs cash-flow analysis.

For non-EU companies, the correct structure should be established before the first shipment. The choice of importer, Incoterms, customs representative and VAT treatment can determine both liability and cash flow.

Conclusion

Customs law in Poland in 2026 should be managed as a financial control function.

The key risks are no longer limited to duty rates.

Importers now need to manage CN classification, customs value, origin, article 33a import VAT, low-value parcel costs, CBAM, ICS2 data quality and post-clearance exposure as one connected process.

For businesses importing significant volumes, three questions deserve immediate attention:

1. Are we paying the correct landed cost?

2. Are we financing import VAT unnecessarily?

3. Could our customs data survive a post-clearance audit?

If any answer is uncertain, a customs and VAT review should take place before the next control rather than after it.
