Why we prepare declarations but do not handle customs filing
Nohena prepares lodgement-ready declarations but does not handle the final customs filing. The act of lodging a declaration with customs is a licensed, regulated activity with legal liability, a responsibility that rests solely with the importer's appointed customs agent. Our function is to provide powerful decision support, not to assume legal representation.
This division of responsibility is a fundamental principle of trade compliance and risk management. The Nigerian legal framework draws a clear line between preparing the information for a declaration and the formal act of submitting it. Understanding this distinction is crucial for any importer or agent focused on efficient and compliant clearance. Our role is to provide foresight and analysis to prepare for a customs filing, not to perform the filing itself. This ensures that the licensed professional, the customs agent, retains ultimate control and accountability over the legal declaration made in their client's name.
What is the legal framework for customs filing?
The legal framework for customs filing in Nigeria is governed by the Customs and Excise Management Act (CEMA) and executed by licensed agents on behalf of importers. This structure establishes a professional class of intermediaries who are held accountable by the Nigeria Customs Service (NCS) for the accuracy and legality of the declarations they lodge. An agent's license is contingent on their adherence to these regulations.
Key aspects of this framework include:
Licensed agents as intermediaries: The NCS authorizes corporate customs brokerage agencies to act on behalf of importers. These agents must demonstrate knowledge of customs laws, tariff classification, valuation, and procedure.
The importer of record's ultimate responsibility: While the agent files the declaration, the importer of record is ultimately responsible for the accuracy of the information provided and for the payment of all duties and taxes. The agent acts as a representative, but the liability chain leads back to the owner of the goods.
The Single Goods Declaration (SGD): This is the official form used for making a customs declaration in Nigeria, submitted electronically through the national trade portal. The agent's digital signature on the SGD is a legal attestation that the information contained within is true and correct to the best of their knowledge.
Regulatory oversight: The NCS has the authority to audit declarations, penalize non-compliance, and suspend or revoke the licenses of agents who fail to meet their professional obligations.
An agent’s liability is non-transferable
A licensed agent’s professional and legal liability for the accuracy of an import declaration cannot be delegated to a third party or a software tool. When an agent lodges a Single Goods Declaration, they are making a legally binding statement to the government. If that statement is found to be false or negligent, the consequences fall directly on the agent and their importing client.
This liability covers several critical areas:
Correct tariff classification: The agent is responsible for ensuring the goods are classified under the correct 10-digit Harmonized System (HS) code from the ECOWAS Common External Tariff (CET). Misclassification can lead to underpayment or overpayment of duties and significant penalties.
Accurate valuation: The declared customs value must comply with the principles of the WTO Valuation Agreement. The agent must ensure the transaction value is correctly reported and that all necessary adjustments, such as freight and insurance, are included. If insurance is not explicitly provided, a default of 1.5% of the goods' value is typically applied for valuation purposes.
Authenticity of documents: The agent attests that the supporting documents, like the commercial invoice, Bill of Lading, and Pre-Arrival Assessment Report (PAAR), are genuine and correspond to the goods being imported.
Compliance with other regulations: The agent must ensure that the import complies with all other government agency requirements, such as securing permits from NAFDAC for food and drugs or SONCAP certificates for regulated products.
The individual who lodges the declaration is accountable for its contents. This accountability is a cornerstone of the customs system and cannot be outsourced.
How decision support differs from customs filing
Decision support provides data analysis and risk foresight to prepare a compliant declaration, whereas customs filing is the formal, legal act of lodging that declaration with customs authorities. The former is an act of preparation and analysis; the latter is an act of legal attestation. A decision support platform helps an agent see a declaration the way a customs risk engine will, flagging potential issues before they become liabilities.
This table outlines the distinct roles:
By using a platform for preparation, an agent can focus their expertise on the most complex aspects of a shipment, armed with better, more consistent data. It transforms their role from manual data entry to strategic risk management. You can learn more about the role of decision support in modern trade compliance .
The anatomy of a lodgement-ready declaration pack
A lodgement-ready declaration pack is a complete and verified set of documents and data that an agent uses to perform the customs filing. Nohena prepares this pack. The quality and consistency of this pack directly impact the speed and predictability of the clearance process. A well-prepared pack minimizes customs queries, interventions, and potential delays.
Here are the essential components:
Form M: An online form filed through a trade portal and transmitted to an Authorized Dealer Bank. It is the first formal notification of an intention to import.
Pre-Arrival Assessment Report (PAAR): Issued by the NCS, the PAAR provides an advisory assessment of the HS code and customs value for the goods before they arrive. It is a critical control document that the final declaration must align with.
Commercial Invoice: The seller's invoice, which must clearly state the value of the goods, currency, and the agreed Incoterms . The value declared here is a primary input for the customs valuation.
Transport Document: Either a Bill of Lading for sea freight or an Air Waybill for air freight, serving as the contract of carriage.
Packing List: A detailed list of the shipment's contents, including weights, dimensions, and quantities, which customs may use for physical inspection.
Single Goods Declaration (SGD): The final declaration form, where all data from the above documents is consolidated. This includes the 10-digit HS code, which determines the duty rate based on the ECOWAS CET, and the calculation of taxes like the 7.5% Value Added Tax (VAT) and levies like the 0.5% ECOWAS Trade Liberalization Scheme (ETLS) charge.
Certificates and Permits: Depending on the goods, this can include a SONCAP certificate for regulated products, NAFDAC permits for food and drugs, or a certificate of origin to claim preferential duties under a trade agreement like the AfCFTA.

The lodgement boundary: where preparation ends and filing begins
The lodgement boundary is the clear line separating the preparatory work of data verification from the legal act of submitting the declaration to the Nigeria Customs Service. Respecting this boundary is essential for maintaining a clear chain of liability. Nohena prepares; the licensed agent lodges.
Our role is to bring the declaration to this boundary in the most compliant, complete, and error-free state possible. We provide the tools to:
Flag inconsistencies between the Form M, PAAR, and commercial invoice to prevent customs queries.
Analyze historical data to recommend the most probable HS classification, reducing the risk of penalties.
Verify all duty and tax calculations for financial accuracy.
Check for required permits based on the HS code, preventing regulatory holds.
The agent then takes this prepared pack, applies their professional judgment, and performs the final, legally significant act of lodging it with customs. This separation of duties creates a system of checks and balances. The technology provides scalable, data-driven foresight, while the agent provides the human expertise and legal accountability required by law. Crossing this boundary would mean becoming a licensed agent, which is a different business with a different legal identity.
FAQ
If you prepare the declaration, why can’t you just click ‘submit’?
The act of clicking ‘submit’ constitutes a formal customs filing, a legal declaration to a government agency. This action is restricted by law to licensed customs agents who carry the professional and financial liability for the declaration's accuracy. Our role is to provide the agent with a thoroughly vetted, lodgement-ready pack to make their filing more efficient and compliant, not to assume their legal liability.
Does using decision support reduce my agent’s responsibility?
No, it enhances their capability. The licensed agent remains fully responsible and legally liable for the declaration. Decision support tools empower the agent by providing deep data analysis and risk foresight, allowing them to exercise their responsibility more effectively. This helps reduce the chance of errors, customs queries, and costly delays.
What happens if there is an error in the prepared documents?
A decision support platform is designed to flag discrepancies and potential risks before a declaration is finalized. The agent's final review is a crucial step to apply their professional judgment and catch any remaining issues. The process is collaborative, with the goal of using technology to assist human expertise in minimizing errors before the agent assumes liability by lodging the declaration.
Can an importer perform their own customs filing in Nigeria?
Customs clearance in Nigeria is a regulated activity. While the importer is the party ultimately responsible for the import, the practical and legal process of clearing goods requires the services of a customs agent or brokerage that is licensed by the Nigeria Customs Service. Direct filing by importers is not the standard operational model for commercial shipments.
