Nigeria Import Duty Basics: Customs Value and HS Codes

Two questions behind every duty bill

When a container reaches a Nigerian port, the customs declaration answers two questions. What are these goods, and what are they worth? The first is classification, expressed as an HS code. The second is customs value. Between them they decide which rate applies and what it applies to, so almost every duty figure an importer sees traces back to one or both.

First-time importers often treat duty as a number the clearing agent produces on arrival. In practice the number is largely fixed earlier, when the supplier writes the invoice and describes the goods. A vague description or an inconsistent value on the paperwork can cost far more time than the duty itself, because the declaration has to be corrected or explained while the container waits in the terminal.

How classification works

The Harmonised System is the international coding structure that customs administrations use to sort goods. Nigeria applies it through its national tariff, and the Nigeria Customs Service assesses declarations against it. Each product falls under a code built from its nature, its material and its use, and the code is what links the goods to a duty rate and to any import conditions attached to them.

Classification is a judgement about the goods, not a free choice. Two products that look alike can sit under different headings because of what they are made of or how they work. A pair of items sold together may be classed differently from the same items sold separately. This is why a precise description matters: model numbers, materials, dimensions and intended use give the classifier something firm to work from.

Mixed consignments need particular care. A container of several different products carries several classifications, and each line on the invoice needs its own clear description. Writing 'assorted goods' or 'spare parts' on an invoice leaves the classifier guessing, and a guess made at the port is rarely the one the importer would have chosen.

Treat the code as part of the product record, not a one-off task. If you reorder the same item every quarter, keep the confirmed code and the description that supported it, and send both to the supplier with each new order. Repeat shipments then follow the same path as the first.

Ask your supplier whether they already use a code for the product in their own export papers. It is a useful starting point, but treat it as a draft. Your forwarder can compare it with the Nigerian tariff before you commit to the order.

How customs value is built

Customs value is normally based on the price actually paid or payable for the goods, adjusted for certain costs connected with bringing them to the port of entry, such as freight and insurance. That is why the terms of sale on your invoice matter. A price quoted on delivered terms and a price quoted at the supplier's factory gate do not describe the same value until the shipping elements are accounted for.

The invoice has to tell a consistent story. Unit prices, quantities and totals should match the packing list and the bill of lading. Discounts, free samples and goods sent at no charge still need to be shown honestly, because customs may query a value that looks too low for the goods described.

Think, too, about how the value is expressed. Name the currency on the invoice and keep the same figures throughout, because the declaration converts the value into naira and a rounding or currency mismatch between documents invites a query. If part of the price is paid separately, for example a commission or a licence fee tied to the goods, tell your forwarder so it can be considered with the declaration rather than discovered later.

Keep proof of payment and the purchase order together with the invoice. If the declared value is questioned, a clear paper trail from order to payment is the quickest way to settle the question.

Where importers lose time

Most duty-related delays are not arguments about rates. They are mismatches: a description on the invoice that does not fit the code, a value that differs between documents, or a product that turns out to need a permit once its classification is confirmed. Each of these is found at assessment, when the container is already in Nigeria and charges are building up.

Raise each of these with your forwarder while the order is still a draft, when a correction costs an email rather than a delay.

Planning your next import with Vandyvah

Vandyvah's customs and freight forwarding team helps importers settle classification and value before the order is paid, so the declaration matches the goods and the paperwork. We review the draft invoice and packing list, coordinate the HS-code description with your supplier, prepare the declaration, and follow the container through assessment and terminal release.

If you are about to place an order, contact the operations team before the cargo ships. A conversation about the product, the supplier's invoice and your delivery plan is the easiest way to avoid surprises at the port.
