Why importers must account for Article 8 additions
Importers often overlook critical costs that must be added to a good’s transaction value, because these costs are not always on the commercial invoice. These mandatory adjustments, known as Article 8 additions , are essential for declaring the correct customs value and avoiding penalties from the Nigeria Customs Service (NCS).
The foundation of modern customs valuation is the World Trade Organization (WTO) Agreement on Customs Valuation, which Nigeria has domesticated. This agreement establishes the transaction value method as the primary basis for determining the customs value of imported goods. This is the price actually paid or payable for the goods when sold for export to the country of importation, plus certain specific adjustments. These adjustments are detailed in Article 8 of the agreement.
Correctly calculating the customs value is not merely about presenting a commercial invoice. It is about constructing a complete and defensible value that includes all legally required components, ensuring compliance and minimizing the risk of costly delays and penalties.

The foundation: transaction value in Nigeria
Transaction value is the primary method used by the Nigeria Customs Service to determine the customs value of imported goods, representing the price actually paid or payable for them. Nigeria, as a member of the WTO, bases its valuation methodology on the principles outlined in the Agreement on Customs Valuation. This means that for the vast majority of imports, the customs duty payable is calculated on a value derived from the actual transaction between the buyer and the seller. This value is declared on the Single Goods Declaration (SGD) and is supported by documents like the commercial invoice, the Form M, and the Pre-Arrival Assessment Report (PAAR).
The goal is to establish a fair, uniform, and neutral system for the valuation of goods that precludes the use of arbitrary or fictitious customs values. However, the price on the invoice is only the starting point. To arrive at the full customs value, or landed cost, one must consider the specific adjustments mandated by Article 8.
A detailed look at Article 8 additions
Article 8 additions are specific costs and charges that a buyer may incur in relation to imported goods which are not included in the price paid to the seller, but which must be added to it to form the complete customs value. These are not optional; they are a legal requirement under the valuation rules. Failing to include them results in an undervalued declaration. The most common additions include:
Commissions and brokerage . Any selling commissions paid by the buyer to the seller's agent must be included. It is important to distinguish this from buying commissions, which are fees paid by an importer to their own agent to represent them abroad in sourcing and purchasing goods. Buying commissions are generally not dutiable additions.
The cost of containers and packing . If the cost of containers, cases, or other packing materials is treated as separate from the goods themselves, this cost must be added to the customs value. This includes the cost of both materials and the labor involved in packing the goods for export.
Assists . This is one of the most frequently missed additions. An assist is the value of certain goods or services that the buyer provides directly or indirectly, free of charge or at a reduced cost, for use in the production of the imported goods. Common examples of assists include: Materials, components, parts, and similar items incorporated in the imported goods.
Tools, dies, moulds, and similar items used in the production of the imported goods.
Materials consumed in the production of the imported goods.
Engineering, development, artwork, design work, and plans and sketches undertaken elsewhere than in Nigeria and necessary for the production of the imported goods.
Royalties and licence fees . The value of any royalty or licence fee related to the imported goods that the buyer must pay, either directly or indirectly, as a condition of sale of the goods being valued, must be added. If the buyer cannot purchase the goods without also paying the royalty, it is considered a condition of sale and must be included in the customs value.
Proceeds of any subsequent resale . If the sales contract stipulates that a part of the proceeds from any resale, disposal, or use of the goods by the buyer will accrue directly or indirectly to the seller, that amount must be added to the price paid.
The cost of transport, insurance, and related charges . Nigeria values goods on a Cost, Insurance, and Freight (CIF) basis. This means the customs value must include the cost of transporting the goods to the port of importation, the cost of insurance covering the shipment, and any associated handling charges. If an importer's invoice is based on different Incoterms, like Free on Board (FOB), these costs must be calculated and added. In the absence of a formal insurance certificate, the NCS will apply a default rate of 1.5% of the FOB value as the insurance cost.
What is not an Article 8 addition?
Certain costs, even if related to the import transaction, are not considered part of the customs value and should not be added to the price paid or payable. Understanding these exclusions is as important as understanding the additions. These costs are generally activities undertaken by the buyer on their own account after the goods have been imported.

The consequences of undervaluation
Failing to declare the correct customs value by omitting Article 8 additions can lead to significant financial and operational penalties for an importer. The Nigeria Customs Service employs a risk management system to identify declarations that appear undervalued. When a declaration is flagged, it can trigger a series of events that disrupt the clearance process and increase costs substantially.
The consequences can include:
Value Uplift . The NCS may reject the declared transaction value and apply an uplift, recalculating the customs value based on one of the other five valuation methods. This almost always results in a higher duty assessment.
Demand Notice (DN) . A formal demand for the additional duties and taxes owed will be issued. This can also include penalties, which can be a significant percentage of the underpaid amount.
Delays and Demurrage . The time taken to resolve a valuation dispute can leave cargo stuck at the port, incurring costly storage (demurrage) and container rental charges.
Increased Scrutiny . Once an importer is flagged for undervaluation, their future shipments are likely to face a higher level of scrutiny, leading to more frequent physical examinations and slower clearance times.
Loss of Reputation . For licensed agents, repeated valuation errors can damage their professional reputation and relationship with the NCS.
Preparing a defensible declaration
The key to avoiding valuation problems is to prepare a complete and defensible customs declaration that correctly accounts for all required costs from the outset. This proactive approach involves a thorough review of all commercial arrangements related to an import, not just the face value of the commercial invoice. An agent should work with the importer to gather all necessary documentation and information before preparing the SGD for lodgement.
This includes:
Reviewing purchase agreements and contracts to identify any clauses related to royalties, resale proceeds, or assists.
Obtaining proof of freight and insurance costs or, failing that, correctly calculating the standard additions.
Documenting any 'assists' by quantifying the value of engineering, moulds, or materials provided to the seller.
Clearly distinguishing between non-dutiable buying commissions and dutiable selling commissions.
Using a decision support system can help flag potential valuation risks and ensure all necessary components of the landed cost are considered. By building a robust and well-documented valuation file, importers and their agents can be prepared to answer any questions from the NCS and defend their declared value. This preparation is the best strategy for ensuring smooth and compliant import clearance.
Ultimately, the responsibility for a correct declaration lies with the importer, and the professional duty of the agent is to guide them. Systems that provide foresight into how a declaration will be viewed by customs risk engines are an invaluable part of a modern agent's toolkit. By understanding and correctly applying the principles of Article 8, you can protect your clients, your business, and your reputation.
FAQ
What is the difference between a buying commission and a selling commission?
A selling commission is a fee paid to the seller's agent or representative, and it must be added to the customs value under Article 8. A buying commission is a fee paid by an importer to their own agent for services like sourcing goods and representing the buyer's interests; this is generally not added to the customs value.
How is insurance calculated if I do not have a certificate?
If an importer cannot provide a formal insurance certificate for their shipment, the Nigeria Customs Service will apply a standard rate of 1.5% of the Free on Board (FOB) value of the goods to calculate the insurance portion of the CIF value for duty assessment.
Are royalties always added to the customs value?
No, not always. Royalties and licence fees are only added to the customs value if they are related to the imported goods and the payment of the fee is a condition of the sale. If the buyer can purchase the goods without paying the royalty, it is typically not considered part of the customs value.
What is an 'assist' in customs valuation?
An assist is a good or service provided by the buyer to the manufacturer free of charge or at a reduced cost, for use in producing the imported goods. Examples include moulds, dies, engineering plans, or raw materials. The value of the assist must be apportioned and added to the customs value of the imported goods.
