Customs transaction value is the price actually paid or payable for imported goods when sold for export to the United States, adjusted by certain statutory additions. It is the default and most commonly used of the six valuation methods Congress codified in 19 U.S.C. 1401a. When transaction value is available and none of the statutory disqualifying conditions apply, CBP is required to use it as the basis for assessing duties.

The links throughout this article go to the primary documents: the statute itself, the implementing regulations, and official CBP guidance. Read the source.

What customs transaction value is and why it matters

Customs value is the starting point for calculating duties, and the method used to determine that value directly affects the dollars an importer owes. An under-declared value creates penalty exposure; an over-declared value means overpaid duties that may be recoverable only through a timely protest.

The United States valuation framework derives from the World Trade Organization Customs Valuation Agreement and is codified at 19 U.S.C. 1401a. The implementing regulations appear at 19 C.F.R. Part 152. CBP has also published extensive informed-compliance guidance on valuation, available through cbp.gov.

Getting valuation right is a component of the reasonable-care standard every importer owes CBP. For a deeper look at that obligation, see our guide on Importer Reasonable Care: What the Mod Act Actually Requires.

The statutory hierarchy under 19 U.S.C. 1401a

Congress established a mandatory sequence. CBP must attempt each method in order and may skip to a later one only when the preceding method is unavailable. The six methods, in order, are:

  1. Transaction value of the imported merchandise (section 1401a(b))
  2. Transaction value of identical merchandise (section 1401a(c))
  3. Transaction value of similar merchandise (section 1401a(d))
  4. Deductive value (section 1401a(e))
  5. Computed value (section 1401a(f))
  6. Fall-back (derived) value (section 1401a(g))

An importer may request that CBP apply deductive value and computed value in reverse order (computed before deductive), but the remaining sequence is fixed. Transaction value governs the vast majority of commercial imports because most arms-length sales satisfy its requirements.

Price actually paid or payable: the legal definition

The statute defines the "price actually paid or payable" as the total payment made, or to be made, by the buyer to or for the benefit of the seller. Several points follow from this definition.

Total payment, not invoice price alone

The relevant figure is not limited to what appears on the commercial invoice. Payments made to a third party on the seller's behalf, indirect payments that reduce a pre-existing debt owed to the seller, and payments made in any currency or in kind all count. CBP looks at the economic reality of the transaction, not its documentary form.

Price for export to the United States

Transaction value applies only when there is a sale for export to the United States. In a multi-tiered distribution chain, the relevant sale is not necessarily the last one. CBP will examine the circumstances to identify which sale qualifies. If goods pass through a middleman who takes title and resells, the first sale doctrine has historically been available, though importers must be able to document it.

Exclusions from the price

Certain amounts are excluded from the price actually paid or payable when they are separately identified and not part of the dutiable value. Common examples include:

Each exclusion requires that the amount be identified separately on the documentation. Bundled charges that cannot be separated from the purchase price remain part of dutiable value.

The five statutory additions to transaction value

Even after the price actually paid or payable is established, 19 U.S.C. 1401a(b)(1) requires five categories of additions when they are not already included in the price and are based on sufficient information:

1. Packing costs

The cost of all containers and coverings, and all expenses of packing (labor and materials), incurred by the buyer. Packing is dutiable regardless of where the packing occurs.

2. Selling commissions

Commissions and brokerage fees paid by the buyer, other than buying commissions. A selling commission is paid to an agent who represents the seller's interests. It must be added when not already in the invoice price.

3. Assists

An assist is any good or service supplied free or at a reduced cost by the buyer to the seller for use in producing or selling the merchandise for export. The statute lists four categories:

Assists are a frequent audit finding. When a U.S. buyer provides tooling or molds to a foreign manufacturer at no charge, the apportioned value of those items must be added to the transaction value of the goods produced with them.

4. Royalties and license fees

Royalties and license fees the buyer is required to pay, directly or indirectly, as a condition of the sale of the imported merchandise. Whether a royalty is "required as a condition of the sale" is a facts-and-circumstances analysis. Payments that relate to the right to reproduce the goods after importation (as opposed to producing or selling them for export) are generally not dutiable.

5. Proceeds of subsequent resale

Any part of the proceeds of any subsequent resale, disposal, or use of the imported merchandise that accrues, directly or indirectly, to the seller. These are sometimes embedded in contract provisions requiring the importer to remit a share of downstream revenue.

When transaction value is unusable: the four disqualifying conditions

Section 1401a(b)(2) lists four conditions under which transaction value cannot be used:

  1. No sale, or no sale for export to the United States. If goods are transferred without a bona fide sale (consignments, leases, gifts, intra-company stock transfers with no sale), there is no price actually paid or payable and transaction value is unavailable.
  2. Disposition or use restrictions. If the sale or price is subject to a condition or consideration for which a value cannot be determined with respect to the goods being valued. For example, a price contingent on the buyer's resale margin that cannot be quantified at the time of entry disqualifies the transaction.
  3. Proceeds of resale accrue to the seller without an appropriate addition. If a portion of resale proceeds flows back to the seller and no addition can be made because sufficient information is unavailable, transaction value fails.
  4. Related-party influence. When the buyer and seller are related, transaction value is usable only if the importer can demonstrate that the relationship did not influence the price, using one of the tests described in the next section.

Related-party transactions: the special rules

The statute defines "related" broadly at 19 U.S.C. 1401a(g)(1). Parties are related if any of the following apply:

The two acceptability tests

When parties are related, the importer must satisfy CBP that the transaction value is acceptable using one of two approaches:

Circumstances of sale test. The importer demonstrates, by examining the circumstances of the sale, that the price was settled in a manner consistent with normal industry pricing practices, or that the price is adequate to cover all costs and provide a representative profit. This is a qualitative, facts-specific showing.

Test values. The importer shows that the transaction value closely approximates one of three test values for merchandise exported to the United States at or about the same time: (a) the transaction value in sales of identical or similar goods to unrelated buyers; (b) the deductive value of identical or similar goods; or (c) the computed value of identical or similar goods. These test values serve as benchmarks. The importer is not required to use the test value as the customs value; it is used only to validate the related-party price.

Transfer pricing and customs value

Many multinationals set intercompany prices under transfer-pricing documentation prepared for income-tax purposes. That documentation does not automatically satisfy CBP's related-party test. The two regimes use different standards and different methodologies. An importer relying on a transfer-pricing study to support customs value must affirmatively connect the study's conclusions to one of the statutory acceptability tests. CBP has issued informed-compliance guidance addressing this overlap, available at cbp.gov.

Maintaining contemporaneous documentation of the related-party test is essential. A post-entry audit that reveals a related-party transaction with no acceptability analysis is a material compliance gap. For a framework to catch these gaps before CBP does, see our guide on building a Post Entry Audit Program: Build a Monthly Self-Review That Catches Errors.
