Dutiable Value: Transaction Value, Fallback Methods, and Penalties

Dutiable value is the dollar figure U.S. Customs and Border Protection assigns to your imported goods to calculate the duties you owe, and for most shipments it starts with the price you actually paid the seller. Federal law sets out six valuation methods that CBP must work through in a fixed order, with the transaction value as the default.¹ Getting the number wrong can trigger civil penalties that scale up to the full domestic value of the merchandise, so the stakes climb quickly for anyone importing commercial quantities.

The Transaction Value: Your Default Starting Point

The transaction value is the total price you actually paid or agreed to pay for goods sold for export to the United States, including every payment, direct or indirect, made to the seller or for the seller’s benefit.¹ International freight, insurance, and related shipping costs are not part of it, and they get subtracted if they were bundled into the invoice price.

Three conditions must be met to use this method. A genuine sale must have taken place between the parties. No restrictions can exist on how you use or dispose of the goods that would meaningfully affect the price. And if you and the seller are related, the relationship cannot have influenced the price.¹

The transaction value is rarely just the invoice figure. Certain costs are added to the price paid; others are subtracted. Most valuation disputes come down to which side of that ledger a particular cost belongs on.

Costs You Add to the Price

If any of the following are not already reflected in the invoice, you add them:¹

Packing costs — containers, crating, and labor the buyer paid to prepare the goods for shipment.
Selling commissions paid by the buyer to the seller’s agent.
Assists — materials, tools, molds, engineering, or design work you provided the manufacturer free or below cost.
Royalties and license fees the buyer must pay as a condition of the sale, whether to the seller or a third party.
Any portion of a later resale, disposal, or use of the goods that flows back to the seller.

Costs You Subtract

The statute excludes transportation, insurance, and related services involved in getting merchandise from the country of exportation to the United States.¹ If your invoice was quoted CIF or on another Incoterm that bundles shipping into the unit price, you deduct the actual freight and insurance to arrive at the dutiable figure. CBP requires these to be actual costs, not estimates or allocations, and expects them backed by invoices, contracts, freight bills, or proof of payment from the carrier or insurer.²

Costs for construction, assembly, or technical assistance performed after importation are also excluded, along with U.S. duties and taxes paid at entry, provided those amounts are separately identifiable in your documentation.

Assists: Where Importers Get Caught

Assists trip importers up more than almost any other add-on, because the value is not obvious and the apportionment rules have teeth. The statute defines four categories: materials or components incorporated into the finished product; tools, dies, and molds used in production; merchandise consumed during manufacturing; and engineering, design work, or plans performed outside the United States that were necessary for production.¹ Design work done by your U.S.-based employee and incidental to other domestic engineering does not count as an assist.

Valuing an assist depends on its nature. Publicly available material, such as a published set of engineering standards, is valued at the cost of obtaining copies. If the assist was partially produced in the United States and partially abroad, only the foreign portion counts.¹

When you supply tooling that will be used across multiple production runs, the assist’s value has to be spread over the imported goods in a reasonable way that follows generally accepted accounting principles. CBP accepts several approaches: allocating the full value to the first shipment, spreading it over the units produced up to the first shipment, or dividing it across the entire anticipated production run if all output will be imported to the United States.³

One method CBP will not accept is IRS depreciation. The agency has explicitly rejected depreciation-based apportionment because it can leave part of the assist’s value permanently outside the duty calculation. Congress intended the full value of every assist to be dutiable, so any method that routinely lets a portion escape is considered unreasonable regardless of whether it complies with tax rules.³

Buying Commissions Versus Selling Commissions

This distinction matters because selling commissions are dutiable and buying commissions are not. A selling commission goes to someone acting on behalf of the seller to make the sale. A buying commission goes to an agent you hired to find, inspect, or negotiate the purchase on your behalf. CBP evaluates the difference on the totality of the evidence, and the burden of proof is entirely on you.⁴

To substantiate a buying commission you need a written agency agreement showing you control the agent’s conduct, evidence that the agent acts primarily for your benefit, and documentation that the agent is financially independent from the manufacturer. The agent should not bear risk of loss for damaged or defective goods, which is a hallmark of a seller or middleman. Every commission must be declared at the time of importation, with the amount identified as a non-dutiable charge on each entry.⁴

When You and the Seller Are Related

If the buyer and seller are related (parent and subsidiary, or companies under common ownership), CBP scrutinizes whether the relationship influenced the price. The agency examines the circumstances of the sale, focusing on how the parties organize their commercial dealings and how the price was determined.⁵

You can demonstrate the relationship did not affect the price by showing any of the following:

The buyer and seller deal with each other as if they were unrelated.
The price is consistent with normal pricing practices in the industry.
The price matches how the seller prices goods to unrelated buyers.
The price covers all costs plus a profit level equivalent to the seller’s overall profit on sales of the same class of goods over a representative period.

If none of these tests are satisfied, CBP rejects the transaction value and moves to the alternative methods. Transfer pricing schedules built for income tax purposes frequently collide with customs valuation rules here. A price that satisfies the IRS does not automatically satisfy CBP.⁵

The Five Fallback Methods

When transaction value cannot be determined or gets rejected, federal law requires CBP to work through a fixed hierarchy. You cannot skip ahead or pick the most favorable option. Each method must be attempted and ruled out before moving to the next.

Identical merchandise. The first fallback uses the transaction value of identical goods, meaning goods that are the same in all respects (physical characteristics, quality, reputation) exported to the United States at or about the same time as your shipment.⁶

Similar merchandise. If no identical goods exist, CBP looks at similar merchandise: goods that share like characteristics and component materials, perform the same functions, and are commercially interchangeable.⁶

Deductive value. CBP starts from the unit price at which the merchandise sold in the greatest aggregate quantity to unrelated U.S. buyers at the first commercial level after import, then subtracts commissions or usual markups, domestic transportation, customs duties, and other post-importation expenses to work backward to an import value.¹

Computed value. This method builds up rather than working down. It sums the cost of materials and production, an amount for profit and general expenses typical for producers in the exporting country selling the same class of goods to the United States, any assists not already included, and packing costs.¹ It requires cooperation from the foreign producer, which makes it impractical in many situations.

Fallback method. If none of the first five methods produce a usable value, CBP derives one by reasonably adjusting the methods above. The law explicitly prohibits basing the value on the selling price of U.S.-produced goods, the domestic market price in the exporting country, minimum values, arbitrary or fictitious values, or a system that selects the higher of two alternatives.¹ Only information available in the United States can be used.

The First Sale Rule in Multi-Tier Supply Chains

When goods pass through a middleman before reaching you (say, a factory sells to a trading company that sells to you), the dutiable value is normally based on the price you paid the trading company, since that is the last sale before importation. The first sale rule lets you base the value on the earlier, lower price the factory charged the middleman instead.⁷

Using the first sale price requires proving that the earlier transaction was a genuine arm’s-length sale and that the goods were clearly destined for export to the United States at the time of that sale. You must declare the first sale basis at entry and insert code “F” at the line-item level on Form 7501. The documentation burden is significant: factory-to-middleman invoices, proof the middleman took title and assumed risk, and evidence the earlier price was negotiated independently. When the paperwork holds up, duty savings on high-volume imports can be substantial.

Samples, Gifts, and Free Goods

Transaction value requires a price actually paid or payable, which means it cannot be used for merchandise you received for free: prototyping samples, warranty replacements, promotional goods, or gifts. These shipments still owe duty in most cases, so CBP moves through the alternative hierarchy to find a value. The common approach is to use the transaction value of identical or similar goods sold around the same time. Declaring “$1” on a sample shipment because no money changed hands is the kind of shortcut that invites a penalty notice.⁸

The statutory de minimis threshold previously let individual shipments valued under $800 enter duty-free.⁹ As of 2026, executive orders have suspended this exemption for all countries, meaning even low-value shipments require proper valuation and are subject to applicable duties.¹⁰

Converting Foreign Currency

Most commercial invoices arrive in a foreign currency, and CBP has rigid rules about which exchange rate applies. The conversion date is the date of exportation, not the date of entry or the date you paid your supplier.¹¹

The rate comes from the Federal Reserve Bank of New York, certified to the Secretary of the Treasury. For most currencies, CBP publishes a quarterly rate in the Customs Bulletin that applies to all exports within that quarter. If the daily certified rate for your specific export date differs from the quarterly rate by 5% or more, you must use the daily rate. When the export date falls on a bank holiday, use the rate from the last preceding business day.¹¹

Your bank’s exchange rate on the day you wired payment is not acceptable for customs purposes, even if it reflects what you actually paid. This is one of the easier errors to make and one of the easier ones for CBP to catch.

Documentation and Filing

CBP requires detailed commercial invoices that go well beyond a typical business invoice. The invoice must show the purchase price of each item in the transaction currency, a detailed merchandise description, quantities in the weights and measures of the exporting country or the United States, all charges on the merchandise itemized by name and amount (freight, insurance, commissions, packing), the country of origin, and any assists provided for production.¹²

Beyond the invoice, you need a bill of lading or airway bill from your carrier confirming shipping costs, and a packing list breaking down the shipment contents. Proof of payment (wire confirmations, letters of credit, or bank statements) substantiates the price you declared. When freight and insurance are bundled into the invoice price, you need separate documentation from the carrier to support deducting those costs.

Every document in the set must be internally consistent. A discrepancy between the invoice amount and the wire transfer, or between the packing list and the invoice quantities, is one of the fastest ways to trigger additional scrutiny.

You report the final dutiable value on CBP Form 7501, the Entry Summary, transmitted electronically through the Automated Commercial Environment (ACE).¹³ Most commercial importers use a licensed customs broker. If CBP questions your declared value, it issues a CBP Form 28, a written request for additional information needed for proper classification or appraisement.¹⁴ An incomplete response can lead CBP to reject your declared value and appraise the merchandise using an alternative method, or open a formal investigation.

Reconciliation for Estimated Values

Sometimes you genuinely do not know the final dutiable value at the time of entry: royalty calculations may still be pending, or assist values may not be finalized. CBP’s Reconciliation program lets you file an entry summary using the best available information and electronically flag the estimated elements for later correction.¹⁵

The deadline for filing a value reconciliation is 21 months from the date of the oldest flagged entry summary. CBP does not grant extensions, so missing it means you lose the ability to correct the entry through this mechanism and could face penalties on any underpaid duties.¹⁵

What Wrong Numbers Cost

Declaring the wrong dutiable value violates 19 U.S.C. § 1592, and the penalty scales with your level of culpability:¹⁶

Fraud: a civil penalty up to the full domestic value of the merchandise.
Gross negligence: up to the lesser of the domestic value or four times the duties the government lost. If the error did not affect duties owed, the cap is 40% of the dutiable value.
Negligence: up to the lesser of the domestic value or two times the lost duties. Where duties were unaffected, the cap is 20% of the dutiable value.

The difference between negligence and gross negligence often comes down to whether you had systems in place to catch the error. An importer who relied on a supplier’s invoice without questioning an obviously below-market price will have a harder time arguing simple negligence than one who can show a documented valuation review process.

Prior Disclosure

If you discover a valuation error before CBP starts an investigation, voluntarily disclosing it substantially reduces your exposure. For grossly negligent or negligent violations that caused a duty loss, the penalty drops to just the interest on the unpaid duties, calculated from the date of liquidation to the date you tender payment. If the error was negligent and did not result in any duty loss, there is no monetary penalty at all.¹⁷

For fraudulent violations, the prior disclosure reduction is less generous: the penalty equals 100% of the total duty loss. That is still far better than the statutory maximum of the full domestic value. The requirement is timing. The disclosure must happen before CBP or another agency has contacted you about the entries in question.¹⁷

Keep the Records for Five Years

Every document supporting your dutiable value calculation must be retained for five years from the date of entry.¹⁸ The clock covers commercial invoices, purchase orders, packing lists, shipping documents, assist calculations, commission agreements, proof of payment, and any correspondence with your supplier related to price or terms.

Failing to produce records when CBP demands them carries separate penalties under 19 U.S.C. § 1509. A willful failure to maintain or retrieve demanded records can result in a penalty up to $100,000 or 75% of the appraised value per release, whichever is less. A negligent failure carries a penalty up to $10,000 or 40% of the appraised value per release, whichever is less.¹⁹ These penalties apply per release of merchandise. If you imported 50 shipments and lost the records for all of them, the exposure multiplies accordingly.
