Customs clearance in the EU is the mandatory declaration process for commercial goods entering, leaving, or moving under customs control across the EU external border.
Customs clearance places goods under a customs procedure, checks the commodity code, confirms customs value and origin, calculates duties and VAT, and authorises release. The legal foundation is Regulation (EU) No 952/2013, known as the Union Customs Code (UCC). The UCC applies across all 27 EU member states.
Every commercial shipment crossing the EU external border requires customs control. This applies to container shipments, air freight shipments, road freight, LCL cargo, reefer containers, and e-commerce imports.
Businesses importing goods into Belgium can use import customs clearance Belgium as the operational entry point for customs declaration, documentation checks, duty calculation, and release coordination.
Who Needs EU Customs Clearance?
EU customs clearance is required by businesses that move commercial goods across the EU external border.
Importers need customs clearance when goods enter the EU from countries such as China, Turkey, the UAE, Saudi Arabia, the USA, Morocco, Nigeria, or Brazil. Exporters need customs clearance when goods leave the EU for a non-EU destination.
Freight forwarders and logistics companies also rely on customs brokers when they coordinate shipments but do not file declarations directly. Cross-border e-commerce sellers need customs clearance when commercial parcels enter the EU customs territory.
Customs clearance is not the same as transport. Transport moves the goods. Customs clearance gives the goods a legal customs status.
Three Customs Procedures Under the EU Union Customs Code
The UCC defines customs procedures that create different legal outcomes for goods.
Import procedure: Goods arriving from outside the EU enter free circulation after customs accepts the declaration and the importer pays or secures the applicable duty and VAT. Free circulation means the goods obtain EU customs status and can move within the single market without another import declaration.
Export procedure: Goods leaving the EU require an export declaration through the national export system. The export declaration supports customs control, exit processing, and VAT zero-rating evidence after the goods physically leave EU customs territory. An Exit Summary Declaration is only required in specific cases where an export or re-export declaration does not contain the required safety and security data.
Transit procedure: Goods can move across EU territory without entering free circulation under a transit declaration. T1 is used for non-Union goods. T2 is used for Union goods moving under transit rules. Transit declarations are processed through NCTS, the New Computerised Transit System, and close at the destination customs office.
For export declaration support, proof-of-exit review, and AES filing coordination, see EU export clearance.
Who Is Responsible for the Customs Declaration?
The importer of record is responsible for the accuracy of import customs data.
A customs broker or customs representative can file the declaration on behalf of the importer. However, the importer remains responsible for correct commercial data, product details, customs value, origin evidence, and import authorisations.
A customs representative can act in two ways:
| Representation type | Meaning | Main responsibility point |
|---|---|---|
| Direct representation | The broker files in the importer’s name and on the importer’s behalf | The importer carries primary customs responsibility |
| Indirect representation | The broker files in their own name but on behalf of the importer | Both parties can carry customs responsibility depending on the case |
This distinction matters for businesses importing controlled goods, high-value cargo, products with preferential origin, and goods exposed to anti-dumping duties or CBAM reporting.

The Five Stages of EU Import Customs Clearance
Import customs clearance follows a defined sequence. Each stage must be correct before goods can be released.
Before the import declaration, many shipments also require safety and security filing through ICS2. ICS2 uses the Entry Summary Declaration (ENS) to provide advance cargo information before goods arrive in the EU. ENS filing is separate from the import customs declaration.
1. Pre-Arrival Notification
Pre-arrival data prepares customs for the incoming shipment before arrival.
The carrier, freight forwarder, logistics provider, or another responsible party may submit safety and security data through ICS2, depending on the transport mode and filing arrangement. The import declaration can also be pre-lodged before the goods arrive where the national system and procedure allow it.
Pre-lodgement reduces port dwell time because customs can assess data before vessel discharge, aircraft arrival, or truck presentation.
2. Electronic Declaration Submission
The customs declaration is submitted through the national customs system of the EU member state where the declaration is lodged.
Belgium uses IDMS for import declarations. PLDA remains temporarily available as fallback for specific cases and operational exceptions. The Netherlands uses DMS after replacing AGS. Germany uses ATLAS. These national systems implement EU customs rules under the UCC.
The declaration includes:
| Data field | Why it matters |
|---|---|
| EORI number | Identifies the importer, exporter, or customs representative |
| CN / TARIC code | Determines duty rate, restrictions, and trade measures |
| Customs value | Calculates import duty and VAT base |
| Country of origin | Determines preferential duty, anti-dumping exposure, and origin controls |
| Incoterm | Shows which costs belong in the customs value |
| Procedure code | Defines whether goods enter free circulation, transit, or another customs procedure |
3. HS Code Classification
HS code classification determines the customs treatment of the goods.
The EU uses the Combined Nomenclature (CN) and TARIC for import classification. The 8-digit CN code identifies the goods at EU level. TARIC adds further measures, such as duty rates, suspensions, quotas, restrictions, anti-dumping duties, and licence requirements.
Classification depends on the objective characteristics of the product at import. Customs does not classify goods by brand name, supplier description, or marketing wording.
Common classification risk areas include textiles, electronics, machinery parts, chemicals, food products, and composite goods. Wrong HS codes can cause duty underpayment, customs penalties, release delays, or post-clearance corrections.
4. Duty and VAT Calculation
Import duty is calculated on the customs value of the goods.
The customs value usually starts with the transaction value. Freight, insurance, assists, royalties, and other additions may be included depending on the Incoterm and valuation rule. CIF, FOB, EXW, and DDP can each affect the declared customs value differently.
Belgium’s standard VAT rate is 21%. Reduced VAT rates can apply to specific goods. Import VAT is calculated on the customs value plus customs duty and certain import-related costs.
Preferential origin can reduce or remove import duty when three conditions are met:
| Requirement | Explanation |
|---|---|
| Valid trade agreement | The EU must have a preferential arrangement with the origin country |
| Qualifying product | The product must satisfy the agreement’s origin rules |
| Valid proof of origin | EUR.1, origin declaration, REX statement, ATR, or other accepted proof must be available |
A non-preferential certificate of origin does not automatically reduce duty. It proves origin for trade policy, statistics, and documentation purposes, but preferential duty requires preferential proof.
For the full regulatory context behind customs value, origin, duty, VAT, and controls, see EU import regulations 2025 Belgium.
5. Customs Release and Free Circulation
Customs release occurs when the customs authority accepts the declaration and clears the goods for the declared procedure.
For release to free circulation, the importer must pay or secure duty and VAT. Customs may also require document checks, licence validation, origin verification, or physical inspection before release.
A Movement Reference Number (MRN) identifies the customs declaration in the customs system. The MRN helps customs, brokers, terminals, and logistics parties track the declaration and release status.
At Belgian seaports, cargo release also depends on port community and terminal release workflows. In Antwerp, IRP and PN/TS support the transition to digital inbound release and temporary storage processes. At Brussels Airport, airport cargo release depends on customs status and handler or cargo-community release messages.
Customs release does not always mean the goods can immediately leave the terminal. The terminal must also receive the correct release confirmation before collection.
Physical inspection can occur during clearance. Customs selects shipments through risk profiling based on product type, origin, value, trader history, route, and document consistency. Inspection can add time to the clearance timeline, especially for food, chemicals, dual-use items, pharmaceuticals, and goods with licence requirements.
Documents Required for EU Customs Clearance
Every customs declaration must be supported by commercial, transport, and regulatory documents.
| Document | Purpose | Mandatory? |
|---|---|---|
| Commercial invoice | Confirms seller, buyer, goods description, value, currency, and Incoterm | Mandatory |
| Packing list | Confirms packages, weights, quantities, and line-item details | Mandatory |
| Bill of lading / AWB / CMR | Links the shipment to sea freight, air freight, or road freight movement | Mandatory |
| EORI number | Identifies the economic operator in EU customs systems | Mandatory |
| HS code / CN code | Classifies the goods for duty, VAT, and restrictions | Mandatory |
| Proof of origin | Supports preferential duty where a trade agreement applies | Conditional |
| Import licence | Required for controlled goods such as dual-use items or regulated products | Conditional |
| Phytosanitary / health certificate | Required for food, plants, animal products, or sanitary-controlled goods | Conditional |
| Insurance certificate | Supports customs value where insurance is part of the valuation | Conditional |
The EORI number is mandatory for customs operations in the EU, including import, export, and transit. One EORI number is valid across EU member states once issued by a national customs authority.
A complete document pack reduces customs questions. It also helps the customs broker verify HS codes, customs value, origin documents, and licence requirements before filing.

How Belgium Administers EU Customs Clearance — IDMS, AES, PLDA and MRN
Belgium administers customs clearance through national customs systems operated by Belgian Customs and FPS Finance.
IDMS is Belgium’s import declaration system for modern import filings. Since the Belgian customs migration, import declarations should be submitted through IDMS where possible. PLDA remains temporarily available as fallback for operational problems and specific exceptions.
AES supports export and exit formalities for goods leaving the EU. NCTS supports transit declarations. PN/TS and IRP support Belgian seaport entry, unloading, temporary storage, and inbound release processes.
| Customs function | Belgium system / process | Practical role |
|---|---|---|
| Import declaration | IDMS | Files import data for free circulation or another import procedure |
| Export and exit | AES | Handles export and exit formalities |
| Transit | NCTS | Handles T1 and T2 transit movements |
| Temporary storage / inbound release | PN/TS and IRP at Belgian seaports | Supports entry, unloading, temporary storage, and release data flows |
| Legacy / fallback | PLDA | Temporary fallback or specific exception cases |
The MRN is the customs reference for the declaration. It allows the importer, customs broker, carrier, terminal, and customs authority to identify the customs movement or declaration.
Belgian customs clearance often involves two linked outcomes:
- Customs approval of the declaration.
- Practical cargo release by the terminal, handler, or port release platform.
A shipment is not ready for collection until both customs status and cargo release status are complete.

Key Terms in EU Customs Clearance
These customs terms appear in most EU import, export, and transit declarations.
Free circulation: Goods have cleared import formalities, duty and VAT have been paid or secured, and the goods hold EU customs status.
SAD (Single Administrative Document): The standard EU customs declaration structure for import, export, and transit data. Electronic systems have replaced paper SAD use in normal commercial filing, but the data logic remains important.
TARIC: The EU integrated customs tariff. TARIC connects CN codes with duty rates, suspensions, quotas, restrictions, anti-dumping duties, and preferential measures.
Pre-lodgement: Filing customs declaration data before goods arrive. Pre-lodgement helps reduce dwell time when documents, HS codes, origin proof, and customs value are complete.
Suspensive procedure: A customs procedure where duty and VAT are suspended until the procedure closes. Common examples include customs warehousing, temporary admission, inward processing, and transit.
MRN: The Movement Reference Number used to identify a customs declaration or customs movement in customs systems.
ENS: The Entry Summary Declaration used for safety and security risk analysis before goods enter or transit through the EU.
EORI: The Economic Operators Registration and Identification number used by businesses and customs representatives for EU customs operations.
