Related-party pricing and customs: how to ensure compliant declarations in Nigeria
To ensure compliant customs declarations for related-party transactions in Nigeria, importers must proactively prove that their relationship did not influence the price, primarily by demonstrating that the price closely approximates a verifiable 'test value' derived from alternative customs valuation methods.
Imports between connected companies, family members, or other associated entities are a standard feature of global trade. However, they present a unique challenge for customs compliance. The core issue is related-party pricing , which can attract significant scrutiny from the Nigeria Customs Service (NCS). Because the buyer and seller are not operating at arm's length, the declared transaction value may not reflect a true market price. This article explains the basis for customs scrutiny, the legal framework for valuation, and the practical steps clearing agents and importers can take to prepare a defensible declaration.
What is related-party pricing and why does customs scrutinize it?
Related-party pricing refers to the value assigned to goods traded between entities with a pre-existing business, personal, or family connection, and it is scrutinized by customs to prevent undervaluation that could reduce duty and tax revenue.
The World Trade Organization (WTO) Valuation Agreement, which forms the basis of Nigerian customs law, provides a clear definition of who is considered a related party in Article 15.4. The relationship exists if:
They are officers or directors of one another’s businesses.
They are legally recognized partners in business.
They are employer and employee.
Any person directly or indirectly owns, controls, or holds 5 percent or more of the outstanding voting stock or shares of both of them.
One of them directly or indirectly controls the other.
Both of them are directly or indirectly controlled by a third person.
Together they directly or indirectly control a third person.
They are members of the same family.
The primary concern for the NCS is the potential for these relationships to facilitate transfer pricing arrangements that artificially lower the invoice value of imported goods. A lower customs value directly translates to lower revenue collection from import duties, which range from 0% to 35% under the ECOWAS Common External Tariff (CET), and other taxes like the 7.5% Value Added Tax (VAT). The NCS is mandated to protect national revenue, so its risk assessment systems are designed to flag transactions that may not reflect a fair, arm's length price.
The legal framework: the WTO valuation agreement and Nigerian law
The primary legal framework governing customs valuation in Nigeria is the Customs and Excise Management Act (CEMA), which incorporates the principles of the WTO Agreement on Customs Valuation, particularly its six-method hierarchy.
The agreement establishes a fair, uniform, and neutral system for valuing goods and prevents the use of arbitrary or fictitious customs values. It mandates a strict hierarchical order for determining customs value. An agent or importer cannot simply choose the most favorable method; they must attempt to use them in sequence.
Transaction Value of Imported Goods (Method 1): This is the primary method, based on the price actually paid or payable for the goods when sold for export to the country of importation. For related-party transactions, the use of this method is conditional.
Transaction Value of Identical Goods (Method 2): Based on the price of identical goods sold to the same country of import.
Transaction Value of Similar Goods (Method 3): Based on the price of similar goods having the same function and commercial interchangeability.
Deductive Value Method (Method 4): Based on the unit price at which the imported goods (or identical or similar goods) are sold in the greatest aggregate quantity to unrelated persons in the country of import, with deductions for certain costs.
Computed Value Method (Method 5): Based on the cost of production of the goods, plus an amount for profit and general expenses.
Fall-back Method (Method 6): If none of the above methods can be used, the value is determined using reasonable means consistent with the principles of the WTO agreement.
The burden of proof falls on the importer. When the NCS has doubts about the acceptability of a declared value in a related-party transaction, it will request further information to confirm that the relationship did not influence the price.
Proving the transaction value: the 'test values' approach
Importers can prove their related-party transaction value is acceptable by demonstrating that it closely approximates one of several pre-defined 'test values' derived from other valuation methods.
According to Article 1.2 of the WTO agreement, the transaction value in a related-party sale shall be accepted if the importer can demonstrate that the price is very close to one of the following, occurring at or about the same time:
The transaction value in sales of identical or similar goods to unrelated buyers in the country of importation (Nigeria).
The deductive value for identical or similar goods.
The computed value for identical or similar goods.
The use of these 'test values' is for comparison purposes only. They do not replace the transaction value as the basis for valuation. Rather, they provide the evidence needed to validate the use of the transaction value (Method 1). Preparing this evidence in advance is a critical part of pre-lodgement compliance.
A framework for demonstrating arm's length pricing
To prepare a defensible declaration, an importer should gather evidence based on the test value they intend to use. The following table outlines the evidence required for each approach.
Documentation is key: preparing a defensible declaration
A defensible customs declaration for a related-party import requires a comprehensive document pack that goes beyond the standard requirements to proactively address potential valuation challenges.
While every import requires core documents like the Form M, Pre-Arrival Assessment Report (PAAR), commercial invoice, and bill of lading, related-party transactions demand a higher standard of proof. The goal is to build a case for the declared value before a customs officer ever asks a question. A lodgement-ready document pack should include:
Standard import documents: The correctly completed Single Goods Declaration (SGD), final invoice, packing list, transport documents, and evidence of payment.
Transfer pricing policy: If the multinational group has a formal transfer pricing study for corporate tax purposes, it can be powerful supporting evidence, provided the pricing is consistent with the customs declaration.
Evidence of test values: This includes invoices for third-party sales, market price lists, or detailed cost breakdowns, as outlined in the table above.
Explanation of the relationship: A letter or statement explaining the nature of the relationship between the buyer and seller and affirming that the price was set on an arm's length basis.
Proof of dutiable additions: Documentation for any costs that must be added to the price paid or payable under WTO Valuation Article 8, such as royalties, license fees, assists (e.g., materials or tools provided by the buyer), or commissions.
Assembling this information allows a licensed agent to present a complete and coherent valuation story to the NCS. Decision support tools can help flag related-party transactions and prompt for the necessary documentation. Nohena prepares a lodgement-ready declaration and document pack; the licensed agent lodges.
Common pitfalls and how to avoid them
Common pitfalls in related-party declarations include inconsistent documentation, failing to account for all dutiable costs, and using arbitrary pricing, which can be avoided through meticulous preparation and adherence to valuation rules.
Inconsistent documentation: A frequent error is declaring a value to customs that does not match the value used for internal accounting or documented in a transfer pricing study. The NCS can and does share information with other revenue authorities, and inconsistencies are a major red flag.
Ignoring 'assists' and other additions: The transaction value is not just the invoice price. It is the 'price paid or payable' plus several mandatory additions outlined in Article 8. Failing to declare the value of a mold provided to the supplier or a royalty fee tied to the imported goods constitutes undervaluation.
Lack of contemporaneous evidence: Providing evidence of third-party sales from two years ago to justify a price today is not persuasive. The test values must be demonstrated 'at or about the same time' as the import.
Confusing customs valuation and corporate tax: While both deal with transfer pricing, their objectives differ. Customs valuation is transactional and focuses on the value of specific goods at the border to assess ad valorem duties. Corporate tax transfer pricing focuses on the overall profitability of entities over a fiscal year. A price acceptable for tax purposes may not be acceptable for customs, and vice versa.

FAQ
What is the difference between transfer pricing for tax and customs valuation?
While both scrutinize prices between related parties, they have different goals. Corporate tax authorities use transfer pricing rules to ensure a company's overall profits are fairly allocated and taxed across jurisdictions. Customs authorities use valuation rules to determine the specific value of an individual shipment of goods at the time of import to correctly assess duties and taxes. A price that is acceptable for one purpose may not be for the other.
Can Nigeria Customs Service reject my declared value even if I have a transfer pricing study?
Yes, the NCS can still reject the value. A transfer pricing study is strong supporting evidence, but it is not binding on customs authorities. The study must be relevant to the specific import transaction, and the valuation method used must be consistent with the principles of the WTO Valuation Agreement. If the study, for example, relies on a profit-based method that is not aligned with the sequential customs valuation methods, the NCS may set it aside and request other evidence.
What happens if the NCS re-values my goods?
If the NCS determines that the declared transaction value is not acceptable and re-values the goods using one of the subsequent valuation methods, it will issue a demand notice for the additional duties and taxes owed. This can also lead to delays in cargo release and potentially trigger penalties for undervaluation. The importer has the right to appeal the decision through established administrative and legal channels.
Does the African Continental Free Trade Area (AfCFTA) affect related-party valuation?
The AfCFTA primarily affects tariffs and rules of origin, not the fundamental principles of customs valuation. For goods to qualify for preferential duty rates under AfCFTA, they must meet the origin criteria (e.g., the ~40% regional value content rule). However, the customs value upon which those preferential duties are calculated must still be determined according to the WTO Valuation Agreement. Therefore, even in an AfCFTA trade, a related-party transaction price must still be proven to be at arm's length.
