Transaction Value and the Additions Customs Requires
The invoice price is where appraisement starts and almost never where it ends. Assists, royalties, selling commissions and resale proceeds are added by statute, and an importer who declares only the invoice has understated value even where nobody intended to.

The rule in short
Under 19 U.S.C. 1401a, imported merchandise is appraised at transaction value: the price actually paid or payable for the goods when sold for exportation to the United States, plus packing costs, selling commissions, the apportioned value of assists, royalties and license fees paid as a condition of sale, and any resale proceeds accruing to the seller. Where the conditions for transaction value are not met, the statute prescribes a fixed hierarchy of alternative methods.
Appraisement is the quieter half of customs compliance. Classification disputes are visible and produce published decisions; valuation errors accumulate silently across thousands of entries and surface in an audit as a single large number. The statute is short, and most of the trouble comes from four or five additions to price that importers do not think of as part of what they paid.
The price actually paid or payable
Transaction value is the price actually paid or payable for the merchandise when sold for exportation to the United States, plus the statutory additions. The phrase is broader than the invoice. It captures the total payment made, or to be made, by the buyer to or for the benefit of the seller, whatever form the payment takes and whenever it is made. A payment routed to a third party at the seller's direction, a debt settled on the seller's behalf, or a side payment for the same goods is part of the price.
Three consequences follow. Payments described as something other than price still count where they are made for the goods. A rebate or price reduction effected after importation is disregarded, so post-entry adjustments do not reduce value unless the mechanism was fixed before importation. And because appraisement in the United States is made on a free-on-board basis, international freight and insurance are not part of value at all, which is the reverse of the practice in most other systems.
The five additions the statute requires
The additions apply whether or not they appear on the commercial invoice, and they are the most common source of understated value. Packing costs incurred by the buyer are added. Selling commissions incurred by the buyer are added, while buying commissions paid to an agent working for the buyer are not — a distinction that depends on what the agent actually does rather than on what the agreement calls it.
The apportioned value of assists is added: materials and components incorporated in the goods, tools, dies and molds used to produce them, merchandise consumed in production, and engineering, design and development work undertaken outside the United States. Royalties and license fees the buyer must pay as a condition of the sale are added, and the operative question is whether the goods could have been bought without paying them. Finally, the value of any proceeds of subsequent resale, disposal or use that accrue to the seller is added.
A buyer who pays a third party for molds and ships them to the factory has supplied an assist, even though no money went to the seller and nothing appears on the invoice. The cost is apportioned across the production run the tooling supports. An importer that has never apportioned tooling across its entries has understated value on every one of them, which is precisely the pattern an audit is designed to find.
When transaction value cannot be used
Transaction value is unavailable where restrictions on the buyer's disposition of the goods materially affect value, where the sale or price is subject to a condition whose value cannot be determined, where proceeds accrue to the seller and cannot be quantified, or where the parties are related and the price was influenced by the relationship. There must also be a sale: consigned goods, samples supplied free of charge and goods shipped between branches of a single company have no transaction value to appraise.
The statute then prescribes an order, and the order is mandatory rather than a menu.
| Method | What it uses | When it is reached | Practical difficulty |
|---|---|---|---|
| Transaction value | Price paid plus the statutory additions | The primary method wherever its conditions are met | Identifying the additions and proving a related-party price |
| Identical or similar merchandise | The accepted transaction value of comparable goods | No usable transaction value for the goods themselves | Finding a comparable sale at the same commercial level |
| Deductive value | The U.S. resale price less commissions, duties, transport and profit | No comparable transaction value available | Isolating deductible costs from the resale price |
| Computed value | Materials and processing, plus profit and general expenses | After deductive value, unless the importer elects to reverse the order | Obtaining cost data from a foreign producer |
| Derived value | A reasonable adjustment of one of the earlier methods | Only when every prior method fails | Justifying the adjustment on the record |
Related parties and the price that must be defended
Relationship does not disqualify a price. It shifts the burden to the importer to show either that the circumstances of the sale indicate the relationship did not influence the price, or that the value closely approximates a test value established from sales to unrelated buyers. The circumstances test is usually met by showing the price was set consistently with the seller's normal pricing practice, or that it recovers all costs plus a profit equivalent to the firm's usual profit on goods of the same class.
Where the intercompany price is set by a transfer pricing policy adjusted after year end, the customs and tax positions have to be built together. A formula fixed before importation, applied objectively, and documented in advance is treated very differently from a discretionary adjustment made later. Importers who have both an upward and a downward adjustment mechanism and disclose only the downward one have a problem that the penalty statute addresses directly.
What else the declared value drives
Entered value is not only the base for the ordinary rate. It is the base for additional tariffs imposed under trade statutes, for antidumping and countervailing duty deposits, for the merchandise processing fee, and for the maximum penalty exposure the statute computes as a share of dutiable or domestic value. It also determines the size of any drawback refund. An error in value therefore propagates through every other number on the entry.
Because of that leverage, importers with long supply chains commonly look at whether an earlier sale in the chain can be used instead, which is a documented and demanding exercise rather than an election. And because the applicable rate itself depends on the heading declared, a valuation strategy built on an unstable classification is a strategy resting on a question that has not actually been settled.
Points to carry away
- The price actually paid or payable includes all payments made by the buyer to or for the benefit of the seller.
- Five additions are required by statute whether or not they appear on the commercial invoice.
- Buying commissions are not added; selling commissions incurred by the buyer are.
- International freight and insurance are not part of value, because appraisement is made on a free-on-board basis.
- A sale between related parties may still be appraised at transaction value if the relationship did not influence the price.
- Where transaction value is unavailable, the statute sets a strict order of alternative methods.
Questions readers ask
Is a price reduction agreed after importation reflected in value?
Generally not. Appraisement looks to the price actually paid or payable for the merchandise when sold for exportation, and a rebate or price reduction effected after the goods are imported is disregarded by statute. Adjustments agreed before importation, and formula prices whose terms were fixed before importation even if the final figure is computed later, are treated differently. That distinction is why transfer pricing adjustments made at year end require careful handling, and why a reconciliation mechanism exists for values that cannot be final at entry.
What is an assist, in practical terms?
Anything of value the buyer supplies free of charge or at reduced cost for use in producing the imported goods: materials and components incorporated in them, tools, dies and molds used to make them, merchandise consumed in production, and engineering, development, artwork, design work and plans undertaken outside the United States. The value of the assist is apportioned over the merchandise it helped produce and added to the price. Tooling supplied to a foreign factory is the classic case importers overlook until an auditor asks who paid for it.
How is a related-party price defended?
By showing either that the circumstances of the sale indicate the relationship did not influence the price, or that the value closely approximates a test value derived from unrelated transactions. The circumstances test usually rests on evidence that the price was settled in a manner consistent with the seller's normal pricing practice, or that it recovers all costs plus a profit equivalent to the firm's overall profit on goods of the same class. Documentation prepared for tax purposes helps but does not by itself decide the customs question.
