How the Customs Value Is Built: CIF, Transaction Value, and What Must Be Added

Most duty disputes are not arguments about the duty rate. They are arguments about the number the rate is applied to. In the UAE that number is the customs value, it is built on a CIF basis, and it is frequently not the same as the total on the commercial invoice.

This guide explains how the value is built, what the law requires you to add, what you must leave out, and where the arithmetic usually goes wrong.

The starting point: transaction value

Under the GCC Common Customs Law, which follows the WTO Agreement on Customs Valuation, the primary method is the transaction value: the price actually paid or payable for the goods when sold for export to the country of importation.

Two words in that sentence do the work. Paid or payable means a price you have not yet settled still counts. Sold for export means the relevant sale is the one that brought the goods to the Gulf, which is not always the last sale in a chain.

Transaction value is the starting point, not the answer. The law then requires certain additions.

The CIF basis

Customs value in the UAE is on a CIF basis: cost, insurance and freight. It includes the cost of transport, insurance and related charges up to the place of importation.

That phrase, up to the place of importation, is the line that decides everything. Costs incurred to get the goods to the UAE port or border are inside the value. Costs incurred after that point are not.

The standard duty rate is five per cent of that value for most goods, so every dirham added or wrongly omitted moves the duty by five fils, and moves the import VAT base by the whole amount.

What the law requires you to add

If these are not already in the invoice price, they have to be added.

Commissions and brokerage, with one exception: buying commissions are not added. A commission paid to your own buying agent for finding and inspecting goods is treated differently from a selling commission built into the deal.

The cost of packing and of containers, where these are treated as part of the goods rather than returnable equipment.

Assists. This is the item most often missed. If you supplied the seller with something free or below cost that was used to make the goods, such as a mould, a tool, a die, a design or materials, its value belongs in the customs value. It is apportioned across the goods produced in a reasonable manner appropriate to the circumstances, which in practice means over the production run the tool serves, not over the first shipment alone.

Royalties and licence fees related to the goods, where they are a condition of the sale. A royalty tied only to the imported goods and readily quantifiable is added. A royalty entangled with other rights, or with financial arrangements between buyer and seller that cannot be separated out, is a signal that transaction value may not be usable at all and another method is needed.

Transport, insurance and related charges to the place of importation, because the basis is CIF.

What must be left out

Costs incurred after importation are not part of the value. That covers the duty and tax themselves, inland transport from the port to your warehouse, and construction, erection or assembly carried out after arrival.

This is where over-declaration happens. An importer working from a delivered-duty-paid invoice, or from a freight bill that runs door to door, will include inland haulage and post-arrival work in the declared value unless someone separates them. That is money given away, and it compounds because import VAT is charged on the same inflated base.

Where the arithmetic goes wrong

Four recurring errors, in rough order of how much they cost.

Insurance that was never bought. If the goods were not insured, there is no insurance cost to add. Adding a notional percentage because a template expects one inflates the value.

Freight on a mixed consignment allocated by line count rather than by weight or value. If one container holds a heavy low-value item and a light high-value one, splitting the freight equally across the lines misstates both. Apportion on a basis that reflects what actually drove the cost, and keep the basis consistent.

Door-to-door freight declared in full. The part of the journey after the place of importation does not belong in the value. Ask the forwarder to split the charge; most will, if asked at booking rather than after the invoice.

Assists left out entirely. Tooling and designs supplied free are the single most common omission, and because they are usually one-off and material, they are also the most likely to surface in a later audit.

When the declared value is questioned

Where an officer has reason to doubt the truth or accuracy of the declared value or the documents supporting it, they may ask for further explanation, including documents or other evidence showing that the declared value represents the total amount actually paid or payable.

That is a request for proof, not an accusation. The answer is documentary: the sale contract or purchase order, proof of payment, the freight and insurance invoices, and a short written explanation of any apportionment you have made.

The importers who answer these quickly are the ones who wrote down their apportionment method when they made it. Reconstructing months later why freight was split a particular way is far harder than recording it at the time.

A short worked structure

Start with the price paid or payable for the goods. Add any selling commissions and brokerage. Add packing and containers. Add the apportioned value of any tooling, materials or designs you supplied. Add royalties and licence fees that are a condition of the sale. Add the freight and insurance actually incurred to the place of importation. Then stop, and exclude everything that happened after arrival.

Applied consistently, that structure survives a query. Applied loosely, it produces a number nobody can explain six months later, which is the real exposure.
