Transfer Pricing and Customs Valuation: What Importers Need to Know About CBP Audit Risk

A large and growing share of U.S. imports involve transactions between related parties — a U.S. subsidiary purchasing goods from its foreign parent, an American manufacturer sourcing from an affiliated overseas plant, a distributor buying from a related supplier in the same corporate family. For these importers, the price declared on the entry is not set by an arm’s-length market negotiation. It is set by an internal transfer pricing policy.

That creates a compliance challenge that many importers underestimate. Transfer pricing is typically managed by a company’s tax or finance team, with the primary objective of satisfying IRS requirements. But U.S. Customs and Border Protection evaluates related-party pricing under a completely separate legal framework, with different standards, different documentation requirements, and different consequences when the declared value does not hold up to scrutiny.

Understanding where those two frameworks diverge — and what CBP is looking for when it reviews related-party transactions — is essential for any importer whose supply chain runs through affiliated entities.

Two Agencies, Two Different Standards

When a U.S. importer buys goods from a related foreign entity, both the IRS and CBP have an interest in the price. But they are asking fundamentally different questions.

The IRS applies the arm’s-length standard: were the goods priced as they would have been between unrelated parties, with profits appropriately allocated between countries? The IRS is concerned with tax liability and profit shifting between jurisdictions.

CBP applies the transaction value method under 19 U.S.C. §1401a: what was the price actually paid or payable for the merchandise when sold for export to the United States, and does that price accurately reflect the dutiable value of the goods? CBP is concerned with whether the correct amount of duty was collected.

These are not the same question. A transfer price that satisfies the IRS arm’s-length standard does not automatically satisfy CBP’s transaction value requirements. A company can be fully compliant with IRS transfer pricing rules and still face a CBP audit finding that its declared customs values were understated.

The most common misconception in related-party import compliance is that a defensible transfer pricing study protects the importer in a CBP audit. It does not. CBP applies its own statutory tests, and the documentation requirements are different.

How CBP Evaluates Related-Party Transaction Value

Under U.S. customs law, transaction value between related parties is acceptable only if the importer can demonstrate one of the following:

The Circumstances of the Sale Test

The importer demonstrates that the transfer price closely approximates the price at which identical or similar goods are sold to unrelated buyers in the U.S. at or about the same time, or that the price covers all costs and includes a profit representative of the seller’s overall profit over a representative period. This test requires documented analysis — not simply an assertion that the price is arm’s length.

Test Values

The declared price closely approximates one of several CBP benchmark values: the transaction value of identical or similar goods sold to unrelated buyers, the deductive value, or the computed value. If the related-party price falls within an acceptable range of these benchmarks, CBP will generally accept transaction value.

If neither test is satisfied, CBP moves to alternative valuation methods in the statutory hierarchy — deductive value, computed value, or the fallback method — which may produce a higher dutiable value than the transfer price and result in additional duties being assessed retroactively.

Audit Exposure: CBP can audit entries up to five years after filing. An importer whose related-party valuation methodology has not been reviewed and documented is carrying five years of potential duty exposure on every entry filed in that period. That exposure compounds quickly for importers with high volumes of related-party transactions.

Dutiable Additions That Importers Miss

Even when CBP accepts transaction value in a related-party transaction, the declared customs value is not simply the invoice price. Certain costs must be added to the declared value under U.S. customs law, and these additions are among the most common sources of undervaluation found in CBP audits of related-party importers.

• Assists: materials, components, tools, molds, dies, or engineering work provided by the U.S. buyer to the foreign manufacturer free of charge or at reduced cost. The value of assists must be added to the customs value of the goods they were used to produce, even if the invoice price does not reflect them
• Royalties and license fees: payments made by the importer to the seller or a third party as a condition of the sale of the imported goods. If the royalty is related to the imported merchandise and is a condition of sale, it is dutiable — regardless of whether it is invoiced separately
• Proceeds of subsequent resale: any amount that accrues to the seller as a result of the resale or use of the imported goods in the United States that is not already reflected in the invoice price
• Packing costs: the cost of containers and packing materials used to ship the goods to the U.S. is included in customs value

For pharmaceutical and biotech importers, royalties and assists are particularly common and particularly easy to miss. A U.S. company that provides formulation knowledge, proprietary manufacturing processes, or tooling to an overseas contract manufacturer may be providing an assist that should be included in the customs value of every shipment produced using those inputs. A licensing arrangement that requires the foreign manufacturer to pay royalties to the U.S. parent may create dutiable royalty additions that flow in the opposite direction. These are the kinds of fact-specific determinations that require careful analysis rather than a standard checklist.

Retroactive Transfer Pricing Adjustments and Customs Reconciliation

Many multinational companies make year-end transfer pricing adjustments — sometimes called “true-ups” — to align intercompany pricing with tax planning objectives after the fiscal year closes. These adjustments raise or lower the effective price of goods that were already imported and entered months earlier.

From a customs compliance standpoint, this creates a specific problem. Duties are assessed at the time of entry based on the declared value. If a year-end adjustment retroactively raises the effective price of imported goods, the importer may have underpaid duties on those entries. If the adjustment lowers the effective price, the situation is more complex: CBP may view the original declared value as inaccurate, and the adjustment may need to be disclosed.

CBP’s reconciliation program exists precisely for this situation. An importer who knows at the time of entry that the transfer price may be subject to a year-end adjustment can flag the entry for reconciliation, allowing the final value to be reported after the adjustment is known. This is the correct procedural path — but it requires proactive planning before the entries are filed, not a corrective response after the adjustment has already been made.

For importers who have already made retroactive adjustments without filing reconciliation entries or post-summary corrections, the question is how much exposure has accumulated and how to address it. A voluntary prior disclosure to CBP, made before CBP initiates its own inquiry, can significantly reduce penalty exposure under 19 U.S.C. §1592.

What CBP Is Looking for in an Audit

Transfer pricing issues appear regularly in CBP’s Focused Assessment audits and risk-based targeting reviews. CBP’s audit team is experienced at identifying the indicators that suggest related-party valuation has not been properly managed:

• Valuation inconsistencies: differences between the customs values declared on entry documents and the values reflected in the importer’s financial records or transfer pricing documentation
• Unreported assists: production tooling, molds, or engineering services provided to a foreign supplier that do not appear in the customs value of the resulting shipments
• Royalty payments not reflected in customs value: license fee payments to related or unrelated parties that are conditions of sale but are not included in the declared value
• Year-end adjustments without reconciliation filings: true-up adjustments that changed the effective price of imported goods but were not disclosed to CBP
• Related-party import volume: importers with a high proportion of related-party transactions are more likely to be selected for review

The best preparation for a CBP audit is the same as the best ongoing compliance practice: accurate declared values, documented methodology for related-party pricing, identified and properly valued dutiable additions, and a reconciliation strategy for entries where the final value is not known at the time of import.

How Euro-American Worldwide Logistics Supports Valuation Compliance

Customs valuation is one of the more technically demanding areas of import compliance, and it is one where the consequences of getting it wrong accumulate quietly across years of entries before surfacing in an audit. Our licensed brokerage team works with importers to review declared customs values, identify dutiable additions that may have been missed, and assess whether related-party pricing methodology is documented in a way that will hold up to CBP review.

For importers with ongoing related-party import programs, that review is most valuable as a proactive exercise — before CBP asks the questions. For importers who have already received a CBP audit notice or who have identified a valuation issue in their own records, we can assist with the corrective filings and CBP response process.
