Valuation is the foundation, not a detail
Customs duty in the EU is expressed as a percentage of the customs value. Import VAT is then applied to the customs value plus the duty. That means a customs value that is off by 10% cascades into duty and VAT errors of a similar magnitude. On any meaningful shipment volume, the compounding effect is material, and it runs in both directions. Under-declaration creates a liability. Over-declaration means you are paying more duty than required and your landed cost model is built on an inflated base.
Yet customs valuation is frequently treated as a clerical task: enter the invoice value, proceed to entry. The invoice price is the right starting point, but in many transactions it is not the full story. The Union Customs Code (UCC) and its Delegated and Implementing Regulations specify exactly what must be added, what must be excluded, and when the invoice price cannot be used at all.
This article covers the rules as they stand at publication. Customs legislation evolves and guidance is updated regularly; consult your customs broker or legal counsel before making valuation decisions on your actual shipments. Nothing here constitutes legal or customs advice.
The transaction-value method: the primary basis
The UCC establishes a hierarchy of six valuation methods. The first (and the one that applies to the vast majority of commercial imports) is the transaction value: the price actually paid or payable for the goods when sold for export to the EU customs territory.
Transaction value can be used when four conditions are satisfied:
- There are no restrictions on the disposal or use of the goods by the buyer, other than restrictions imposed by law, geographic limitations on resale, or limitations that do not materially affect the value.
- The sale or price is not subject to conditions or considerations for which a value cannot be determined.
- No part of the proceeds of any subsequent resale, disposal, or use by the buyer will accrue to the seller, unless an appropriate adjustment can be made.
- The buyer and seller are not related, or, if they are related, the transaction value is acceptable as customs value under a separate test.
When those conditions are met, the invoice price (adjusted for the additions and exclusions described below) is your customs value. When they are not met, you work through the fallback methods in sequence.
What must be added to the invoice price
The UCC requires certain items to be added to the transaction value if they are not already included in the price paid or payable. These additions are not optional; omitting them is a valuation error.
Commissions and brokerage
Selling commissions paid by the buyer must be added. Buying commissions (fees paid to an agent acting purely on behalf of the buyer) are excluded. The distinction matters and is sometimes disputed: an agent who also represents the seller, or who has a financial interest in the transaction, may not qualify as a buying agent.
Containers and packing
The cost of containers treated as one with the goods for customs purposes, and all packing costs (labour and materials), must be added if not already in the price.
Assists
An assist is any good or service supplied by the buyer, free of charge or at reduced cost, for use in connection with the production or sale of the imported goods. Common examples include: tooling, moulds, or dies provided to the manufacturer; materials or components incorporated into the goods; engineering, development, artwork, or design work undertaken outside the EU and necessary for the production. The value of assists must be added to the customs value. Many importers overlook assists because they are not on the commercial invoice. They exist as separate supply arrangements. Failing to declare them is a valuation error regardless of intent.
Royalties and licence fees
Royalties and licence fees related to the imported goods that the buyer must pay as a condition of the sale must be added to the transaction value. The test is whether the seller would not sell the goods without payment of the royalty. If the royalty is paid to a third party unrelated to the seller, and the seller does not require it as a condition of sale, it may be excluded, but the analysis requires care.
Proceeds of resale
Any part of the proceeds of any subsequent resale, disposal, or use of the goods that accrues, directly or indirectly, to the seller must be added.
Transport and insurance costs to the EU border
The EU uses a CIF-based customs value: the cost of transport and insurance to the point of introduction into the EU customs territory must be included. If goods are sold on FOB terms and freight and insurance are not in the invoice price, they must be added. If goods are sold on DDP or DAP terms, the freight and insurance component to the EU entry point is part of the price but costs incurred inside the EU should be deducted.
What is excluded from the customs value
Certain items are excluded from the customs value provided they are shown separately from the price paid or payable:
- Charges for construction, erection, assembly, maintenance, or technical assistance undertaken after importation.
- Transport costs incurred within the EU customs territory after entry.
- Customs duties and other taxes payable in the EU upon importation.
- Buying commissions (as distinguished from selling commissions above).
- Interest charges on financing arrangements for the purchase, provided the interest is separately identified and the financing is on terms comparable to market rates.
The key requirement for exclusions is that the relevant amounts are distinguished in the documentation. A lump-sum price that bundles installation, post-import freight, and the goods themselves will require unbundling before an exclusion can be applied.
The six-method hierarchy
When the transaction-value method cannot be used (most commonly because the buyer and seller are related and the transaction value cannot be shown to be acceptable), the UCC requires customs authorities to work through five fallback methods in a fixed sequence:
- Transaction value of identical goods: the customs value of identical goods sold for export to the EU at the same commercial level and in substantially the same quantity, imported at or about the same time.
- Transaction value of similar goods: as above, but for goods that are not identical but have like characteristics and materials, perform the same functions, and are commercially interchangeable.
- Deductive value: based on the unit selling price of the imported (or identical or similar) goods in the EU, less deductions for commissions, profit, general expenses, duties, taxes, and domestic transport costs.
- Computed value: based on the cost of materials and fabrication, plus amounts for profit and general expenses typical of the industry.
- Fall-back method: a flexible application of the preceding methods with reasonable flexibility, or an alternative basis acceptable to customs authorities.
In practice, most importers never reach the fallback methods. But understanding that they exist, and that customs authorities have the power to apply them when the transaction value is questioned, underlines why getting valuation right at the outset matters more than treating it as a secondary concern.
Related-party transactions: the added layer
When the buyer and seller are related (parent and subsidiary, sister companies, companies with common ownership or control, or parties with a business relationship that could influence the price), customs authorities may examine whether the relationship influenced the price. This does not mean the transaction value is automatically rejected, but the importer should be prepared to demonstrate one of three things:
- The transaction value closely approximates the customs value of identical or similar goods sold to unrelated buyers at the same time.
- The transaction value closely approximates the deductive or computed value.
- The price was settled in a manner consistent with normal industry pricing practices.
Transfer pricing documentation used for tax purposes is not the same as customs valuation documentation, though there is overlap. If your group has intercompany trade at managed transfer prices, valuation risk at the customs border deserves specific attention, separate from the tax analysis.
Valuation, duty, and landed cost: the cascade
Customs value is the input to the duty calculation. Import VAT is applied to the customs value plus duty. Both feed directly into landed cost. An error in customs value propagates through each layer: understating value reduces duty and VAT paid in the short term but creates a liability; overstating inflates landed cost and distorts sourcing comparisons.

Common importer mistakes
Omitting assists from the declared value
Tooling, moulds, and design work supplied to suppliers are assists. They belong in the customs value. Because they never appear on a commercial invoice, they are routinely omitted. Customs authorities conducting post-clearance audits look for exactly this.
Misclassifying selling commissions as buying commissions
The distinction between a selling commission (added to the customs value) and a buying commission (excluded) depends on who the agent legally represents and in whose interest they act, not what the contract calls them. Agents who receive commission from both parties, or whose primary relationship is with the seller, are not buying agents for customs purposes.
Declaring the FOB price without adding freight and insurance
The EU requires a CIF-based customs value. If the commercial invoice is on FOB terms and freight and insurance are on separate documents, they must still be added to arrive at the correct customs value. Using the invoice price alone understates the dutiable value.
Using the same price for related-party transactions without any supporting analysis
Declaring transfer prices as customs value without any documentation of comparability or alternative test is a risk exposure. It does not mean the price is wrong; it means you cannot demonstrate that it is right if challenged.
Assuming last year's approach is still correct
Customs valuation guidance, case law, and regulatory practice evolve. An approach that was accepted in a previous period may not be accepted in a current audit if the regulatory environment has changed. Periodic review is worth the time.
Why valuation drives your real landed cost
Every duty rate in the EU tariff is a percentage of the customs value. Anti-dumping and countervailing duties are also typically expressed as percentages or specific amounts tied to the customs value. CBAM operates on a different basis (embedded emissions rather than value), but customs duty and import VAT, two of the largest variable components of landed cost, are direct functions of the declared value.
An importer who consistently under-declares misses the true cost of their goods until a post-clearance audit arrives. An importer who over-declares is paying more duty and VAT than required, and their landed cost model overstates the cost of each shipment, leading to conservative sourcing decisions or inflated pricing that erodes competitiveness. Neither outcome is useful. The goal is a correct customs value, derived from a systematic process applied consistently across shipments.
