Key takeaways

  • Import Declaration N10 applies to all importers releasing goods into free circulation in the EU.
  • The declaration must include key data elements such as importer and declarant identification, commodity details, and commercial references.
  • An EORI number is essential for importers and declarants to identify themselves to customs authorities.
  • Preferential tariff treatment claims require submitting origin declarations and may involve additional documentation.
  • Anti-dumping and countervailing duties require compliance with specific invoicing and certification conditions.
  • Declarants and representatives have distinct roles and responsibilities in the customs declaration process.
  • Proper documentation and record-keeping are mandatory to support the declaration and claims made.
  • Deadlines for submission and consequences of non-compliance, including customs debts, are strictly enforced.

Who is Affected by Import Declaration N10 Requirements?

Import Declaration N10 requirements apply primarily to importers and their representatives who bring goods into the EU single market for release into free circulation. This includes any natural or legal person who makes or on whose behalf the declaration is made. The declarant may be the importer or a customs representative acting on the importer’s behalf [1:1].

The importer must be identified by an Economic Operators Registration and Identification (EORI) number, which is mandatory for customs procedures within the EU. If the importer does not have an EORI number, the customs administration of the relevant Member State may assign an ad hoc number for the specific declaration [1:2].

Businesses importing goods subject to preferential tariff treatment or anti-dumping duties must also comply with additional obligations to benefit from tariff reductions or exemptions [2:1][3].

Key Data Elements for Your N10 Declaration

The import declaration N10 requires several critical data elements to be submitted accurately:

  • Name and address of the importer: The party making or on whose behalf the declaration is made must be clearly identified [1:3].
  • Importer identification number: The EORI number of the importer or an ad hoc number if not registered [1:4].
  • Declarant information: Full name, address, and EORI number of the declarant who submits the declaration [1:5].
  • Representative information: Where applicable, details of the customs representative distinct from the declarant [1:6].
  • Unique commercial reference number: A unique identifier such as a WCO (ISO 15459) code assigned to the consignment [4].
  • Local reference number (LRN): Nationally defined number allocated to each declaration in agreement with customs authorities [4:1].
  • Warehouse identification: Codes and authorisation numbers for storage facilities if goods are placed under customs warehousing [4:2].
  • Deferred payment authorisation: Reference data for deferred payment of import duties or taxes, if applicable [4:3].

These data elements allow customs authorities to process the declaration efficiently and verify compliance with customs regulations.

EORI Number: Your Essential Identifier

The EORI number is a unique identifier assigned to economic operators engaging in customs activities within the EU. It is a prerequisite for submitting an import declaration N10. Both the importer and the declarant must provide their EORI numbers in the declaration [1:7].

If an importer or declarant is not established in the EU or is not an economic operator, the customs authority of the Member State may assign an ad hoc identification number for the specific transaction [1:8].

Having an EORI number ensures seamless communication with customs authorities and is essential for compliance with the Union Customs Code and its implementing regulations.

Special Considerations for Preferential Treatment and Anti-Dumping Duties

Importers claiming preferential tariff treatment under trade agreements such as the Comprehensive Economic and Trade Agreement (CETA) must submit an origin declaration to the customs authority of the Member State of import. This declaration must comply with the procedures applicable in that Member State and may require translation or accompanying statements to confirm that the goods meet the conditions for preferential treatment [3:1].

If an importer becomes aware that an origin declaration contains incorrect information, they must notify the customs authority immediately and pay any duties owed [3:2].

Anti-dumping and countervailing duties apply to certain products, such as crystalline silicon photovoltaic modules from China or biodiesel from Argentina. Imports may be exempt from these duties if accompanied by specific undertaking invoices and export certificates as stipulated by the relevant Commission Implementing Regulations. The goods declared must correspond precisely to the description on the undertaking invoice [2:2][5][6].

Failure to meet these conditions results in the incurrence of a customs debt at the time of acceptance of the declaration [2:3][5:1].

Understanding Declarant and Representative Roles

The declarant is the person who lodges the import declaration and is responsible for the accuracy and completeness of the information provided. This may be the importer or a customs representative acting on their behalf. The declarant must provide their full name, address, and EORI number [1:9].

The representative is a person or entity acting on behalf of the declarant, for example, a customs agent or freight forwarder. When the representative differs from the declarant, their identification details must also be included in the declaration [1:10].

Both parties have obligations under the Union Customs Code to ensure compliance. The declarant is ultimately responsible for the correctness of the declaration, while the representative acts under a mandate and must ensure that the declaration is submitted properly.

Documentation and Record-Keeping Obligations

Importers must maintain and, upon request, provide supporting documents to customs authorities to substantiate the information declared in the import declaration N10. This includes commercial invoices, transport documents, certificates of origin, supplier’s declarations, and any other relevant paperwork [7][8].

For preferential origin claims, supplier’s declarations must be accurate and may cover multiple shipments over a period. These declarations must specify non-originating materials used and confirm compliance with the applicable rules of origin [7:1][8:1].

Proper record-keeping facilitates audits and controls by customs authorities and supports claims for preferential tariff treatment or exemptions from anti-dumping duties.

Deadlines and Consequences of Non-Compliance

The import declaration N10 must be submitted before the goods are released into free circulation. Customs authorities set specific deadlines for submission, which vary depending on the Member State and the type of goods.

Failure to submit the declaration on time or providing incorrect or incomplete information can lead to penalties, delays, or the imposition of customs debts. For example, if conditions for exemption from countervailing duties are not met, a customs debt arises at the time the declaration is accepted [2:4][5:2].

Importers should ensure timely and accurate submission of import declaration N10 to avoid financial and operational consequences.
