How to claim preferential tariffs with the ECOWAS ETLS
To claim preferential treatment under the ECOWAS ETLS, an importer must present a valid ECOWAS Certificate of Origin to the Nigeria Customs Service alongside their standard import documents for eligible goods originating from a member state.
The Economic Community of West African States (ECOWAS) Trade Liberalisation Scheme, or ETLS, is a foundational instrument for regional economic integration. It is designed to reduce barriers and promote trade among its member states by allowing qualifying goods to be imported at a zero percent customs duty rate. For Nigerian importers sourcing goods from the region, understanding the mechanics of the ETLS is critical for reducing landed costs and improving supply chain efficiency. This process, however, demands precision in documentation and a clear understanding of the rules that govern eligibility.
What the ECOWAS ETLS is and who is eligible
The ECOWAS Trade Liberalisation Scheme is a regional trade agreement that eliminates customs duties and equivalent taxes on qualifying goods traded between its fifteen member states. The scheme aims to establish a free trade area, which is a crucial step toward creating a common market in West Africa. The fifteen member states are Benin, Burkina Faso, Cabo Verde, Côte d'Ivoire, The Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo.
Eligibility for ETLS benefits is not automatic. It is determined by the origin of the goods, which fall into two primary categories:
Unprocessed goods: These are raw materials and products that are wholly obtained within the ECOWAS region. This includes agricultural produce grown and harvested in a member state, live animals born and raised in the region, and minerals extracted from its soil.
Industrial products: These are manufactured or processed goods that have undergone substantial transformation within an ECOWAS member state. These products must satisfy specific rules of origin to qualify.
It is important to distinguish the ETLS from the ECOWAS Community Levy. The Community Levy is a 0.5% tax applied to the CIF value of goods imported from non-ECOWAS countries. These funds are used to finance the operations of the ECOWAS Commission and its institutions. Goods traded under the ETLS are exempt from this levy.
Understanding the rules of origin for ETLS
For goods to qualify for ETLS benefits, they must satisfy specific rules of origin criteria, proving they originate from within the ECOWAS region. These rules are the technical foundation of the scheme, designed to prevent trade deflection, where goods from outside the bloc are simply transshipped through a member state to avoid tariffs. The criteria differ for unprocessed and industrial goods.
Criteria for unprocessed goods
Unprocessed goods must be 'wholly obtained' in an ECOWAS member state. This is the most straightforward origin criterion. Examples include:
Crops harvested within a member country.
Live animals born and raised within the community.
Fish and other marine products harvested from the territorial waters of a member state.
Minerals and other natural resources extracted from the land or seabed within the community.
Criteria for industrial products
Industrial products are subject to more complex rules to demonstrate that sufficient value was created or transformation occurred within the region. A product is considered to have originated from ECOWAS if it meets one of the following primary conditions:
Change in Tariff Heading: The production process must result in a final product that is classified under a different four-digit Harmonized System (HS) code than its non-originating raw materials.
Value-Added Requirement: The value added during the production process must be at least 35% of the ex-works price of the finished goods. Alternatively, the total value of imported raw materials from non-ECOWAS countries must not exceed 60% of the total cost of all raw materials used.
Furthermore, the company producing the goods must itself be approved under the ETLS scheme. This involves an application to a National Approval Committee in the exporting country, which verifies that the company's production processes comply with the rules of origin.
How to claim preferential treatment: a step-by-step guide
Claiming ETLS preference involves a sequence of actions by both the exporter and the importer, culminating in the presentation of a valid Certificate of Origin to the destination customs authority.
Step 1: The exporter obtains ETLS approval and the Certificate of Origin The process begins in the exporting country. The company manufacturing the goods must first be registered and approved by its National Approval Committee for the ETLS. Once the company is approved, it can apply for an ECOWAS Certificate of Origin for each specific shipment. This application is submitted to a designated authority, often the Ministry of Trade or Chamber of Commerce, and must be supported by evidence that the goods meet the origin criteria.
Step 2: The importer initiates the Form M and PAAR process In Nigeria, the importer or their agent initiates the import process by obtaining a Form M through the Nigeria Single Window for Trade portal. It is critical at this stage to indicate the intent to claim preferential treatment under the ECOWAS ETLS. The subsequent Pro-forma Invoice, insurance certificate, and other documents are used to generate the Pre-Arrival Assessment Report (PAAR). While the PAAR provides an initial assessment, the final duty determination by the Nigeria Customs Service depends on the documents presented at the time of clearance.
Step 3: The agent prepares the declaration and supporting documents For customs clearance, the licensed agent prepares the Single Goods Declaration (SGD). The declaration must correctly state the preferential treatment being claimed, using the appropriate customs procedure code. The cornerstone of the claim is the original, stamped ECOWAS Certificate of Origin. This must be presented as part of a complete document pack, which includes: The original ECOWAS Certificate of Origin
The final Commercial Invoice
The Bill of Lading or Air Waybill
The Packing List
The PAAR document
The SGD
Any other applicable regulatory documents, such as a SONCAP certificate or NAFDAC permit
Step 4: Customs verifies the claim The Nigeria Customs Service (NCS) at the port or border is responsible for verifying the legitimacy of the ETLS claim. An officer will scrutinize the Certificate of Origin for authenticity, checking for correct stamps, signatures, and dates. The information on the certificate, such as the HS code, description of goods, and quantities, will be cross-referenced against the commercial invoice, bill of lading, and SGD. Any discrepancy can lead to the rejection of the claim. The NCS may also physically inspect the goods to ensure they match the declaration. If all documents are valid and consistent, the goods are assessed at 0% customs duty. Other statutory charges, such as the 7.5% Value Added Tax (VAT), remain applicable.
Comparing ETLS and AfCFTA rules of origin
While both the ETLS and the African Continental Free Trade Area (AfCFTA) aim to boost intra-African trade, they are separate agreements with distinct rules of origin and implementation statuses. It is essential for practitioners to understand which agreement applies to a given transaction.
An importer cannot use an AfCFTA Certificate of Origin to claim benefits under the ETLS, or vice versa. Each scheme requires its own specific documentation. For more analysis of regional trade policies, you can explore our other articles in our insights section .
Common pitfalls when claiming ETLS preference
Errors in documentation, mismatched information, and invalid Certificates of Origin are the most frequent reasons for the rejection of ETLS claims. A rejected claim results in the application of the standard MFN duty rate under the ECOWAS Common External Tariff (CET), which can significantly increase costs.
Invalid Certificate of Origin: A certificate may be rejected if it is expired (they are typically valid for six months), lacks the proper stamps or signatures from the designated issuing authority, or contains handwritten alterations.
Documentary discrepancies: Customs authorities meticulously check for consistency across all documents. A mismatch in the HS code, gross weight, value, or description of goods between the Certificate of Origin, invoice, and bill of lading is a common red flag.
Transshipment issues: Goods should ideally be shipped directly from the exporting member state to the importing one. If goods transit through a non-ECOWAS country, the importer must provide evidence to customs that the goods remained under customs control and were not altered or substituted during transit.
Ineligible goods: Attempting to claim preference for goods that do not meet the rules of origin is a frequent error. This includes products that are merely repackaged or have undergone only minor processing without substantial transformation.
The ECOWAS ETLS offers a significant competitive advantage to importers who can navigate its requirements correctly. The key is documentary diligence. Preparing a lodgement-ready declaration pack with fully aligned documents is the best way to ensure a smooth clearance process. Decision support systems can help identify potential discrepancies in your documents before they are presented to customs, providing foresight into how a risk engine will view the declaration.

FAQ
Do I still pay VAT and other levies on ETLS goods?
Yes. The ECOWAS ETLS provides an exemption from customs import duty only. Other fiscal charges, such as the 7.5% Value Added Tax (VAT), port surcharges, and other local levies, are still applicable based on the value of the goods.
What happens if my Certificate of Origin has an error?
If the Nigeria Customs Service identifies a significant error or discrepancy on the Certificate of Origin, or if they cannot verify its authenticity, the claim for preferential treatment will be rejected. The goods will then be assessed with the standard duty rate applicable under the ECOWAS Common External Tariff (CET).
Can I use goods from Ghana to manufacture a product in Nigeria and export it to Senegal under ETLS?
Yes, this is a core principle of the scheme known as diagonal cumulation. As long as the inputs from Ghana (an ECOWAS member) and the processing in Nigeria result in a final product that meets the ETLS rules of origin, it can be exported to another member state like Senegal with a Nigerian-issued ECOWAS Certificate of Origin.
How long is an ECOWAS Certificate of Origin valid?
An ECOWAS Certificate of Origin is valid for a period of six months from its date of issuance by the competent authority in the exporting country. The certificate must be valid at the time it is presented to the customs authorities in the importing country.
What is the difference between the ETLS and the ECOWAS Community Levy?
The ETLS is a free trade scheme that allows for 0% customs duty on qualifying goods traded between member states. The ECOWAS Community Levy is a 0.5% tax imposed on the CIF value of goods imported from countries outside of ECOWAS. The levy funds the community's institutions, while the ETLS facilitates trade within it.
