A correct customs declaration is essential for a smooth international flow of goods. When you import or export goods, customs authorities require specific information about the shipment, the goods and the parties involved. Missing or incorrect information can lead to delays, additional costs or even fines.
Within the supply chain, the customs declaration forms an important part of the logistics process. Proper preparation helps goods move through customs more quickly and reduces risks.
Which information is required for a customs declaration?
For a correct customs declaration, you need various pieces of information and supporting documents. The exact requirements differ by country, product category and customs procedure, but several elements are almost always required.
EORI number
An EORI number (Economic Operators Registration and Identification) is a unique identification number for companies trading with countries outside the European Union. Without a valid EORI number, in many cases you cannot submit an import or export declaration.
Commercial invoice
The commercial invoice forms the basis of every customs declaration. It contains details of the sender and recipient, a clear description of the goods, the quantity, the value of the goods, the currency used and the agreed delivery terms (Incoterms). An incomplete invoice is one of the most common causes of customs delays.
HS code
The HS code determines the product category under which your goods are classified. Customs authorities use this code for calculating import duties, statistical purposes and checking whether any import restrictions apply. An incorrect HS code can lead to additional inspections, reassessments or delays in the flow of goods.
Origin of the goods
The country of origin also plays an important role. This is the country where the goods were actually produced or manufactured. The origin can affect import duties, trade agreements and any preferential tariff arrangements.
Transport documents
In addition to the above information, supplementary transport documents are often required, such as a CMR consignment note, packing list or other transport documentation. It is important that these documents fully correspond with the information included in the customs declaration.
What does this mean in practice?
Many companies view a customs declaration primarily as an administrative obligation. In reality, the quality of a declaration directly impacts supply chain performance. When information is inconsistent or incomplete, customs may select a shipment for additional inspections. This often results in delays, extra costs and disruptions to planning.
In practice, problems regularly arise because invoice details do not match transport documents, an incorrect HS code is used, the value of the goods is declared incorrectly or mandatory origin information is missing. For companies operating with strict delivery schedules, such errors can have significant consequences for delivery reliability and customer satisfaction.
How does the customs declaration process work?
A correct customs declaration starts well before the goods reach the border.
Step 1: Collecting information
All relevant information about the goods is collected. This includes product information, invoices, origin data and transport documents.
Step 2: Classifying the goods
A correct HS code is determined for each product category. This forms an important basis for the further customs process.
Step 3: Preparing the declaration
The required information is entered into the customs system. This includes the value of the goods, origin, commodity code and details of the parties involved.
Step 4: Customs assessment
Customs authorities review the submitted information. Depending on the risk profile, the shipment may be released immediately or selected for additional inspections.
Step 5: Release of goods
Once approved, the goods can continue their journey to a warehouse, distribution centre or final destination.
Why are customs declarations rejected?
A large proportion of problems arise from relatively simple mistakes.
Common causes include:
- Incorrect HS codes
- Inconsistent product descriptions
- Incorrectly declared goods values
- Missing origin information
- Incomplete commercial invoices
These errors may seem minor, but they can result in delays, additional inspections and unexpected costs.
Benefits and points of attention
Benefits of a correct customs declaration
Faster shipment processing
Correct documentation reduces the risk of delays at border crossings.
Greater cost control
Proper classification and valuation help prevent unexpected reassessments and additional charges.
Improved compliance
You comply with national and international customs regulations.
A more reliable supply chain
A predictable customs process supports reliable deliveries to customers.
Points of attention
Regulations change regularly
Customs regulations, trade agreements and import requirements are updated on a regular basis.
Responsibility remains with the goods owner
Even when a freight forwarder or logistics service provider prepares the declaration, the owner of the goods remains responsible for the accuracy of the information supplied.
Strong internal processes are essential
Errors often occur when information from different systems does not align properly.
How can a logistics partner support this process?
International logistics requires more than transportation alone. Proper document preparation, visibility into goods flows and coordination between all involved parties play an important role in smooth customs clearance.
A logistics partner can provide support by aligning transportation, warehousing and administrative processes more effectively. This creates greater visibility throughout the supply chain and reduces the risk of errors.
Companies looking to further professionalise their logistics operations often combine customs processes with services such as contract logistics and warehousing. In addition, a well-organised network for international transport can contribute to more efficient handling of cross-border shipments.
