The bill amends Section 402 of the Tariff Act of 1930 (19 U.S.C. 1401a) by adding a targeted definition of “sold for exportation to the United States.” For single-sale transactions, valuation will be the price actually paid or payable by the U.S. buyer to a foreign seller; for chains of sales, valuation will be the price paid by the U.S. buyer in the last sale that introduces the merchandise into the United States. The bill also inserts language expressly authorizing U.S. Customs and Border Protection (CBP) to access books and records when making valuation adjustments.
This changes the transactional anchor for customs valuation and clarifies CBP’s documentary access for adjustments. The practical result is a shift in where duties are measured in a sales chain, which affects importers, foreign sellers, customs brokers, and downstream enforcement.
It tightens the legal basis for CBP examinations and may increase documentation and compliance requirements around cross-border distribution chains.
At a Glance
What It Does
The bill adds subsection (b)(4)(C) to 19 U.S.C. 1401a to define “sold for exportation to the United States” as the price actually paid or payable by the U.S. buyer — and, in chains of sales, as the price in the last sale that introduces the merchandise into the United States. It also expands the language in subsection (h)(5) to state that adjustments include access to books and records by CBP.
Who It Affects
Importers of record, foreign producers and intermediaries in multi-stage supply chains, customs brokers, and compliance teams will be directly affected because the valuation base may shift to a different transactional link and because CBP gains explicit record-access authority for adjustments. U.S. manufacturers and domestic producers could be indirectly affected through changes in duty outcomes.
Why It Matters
By specifying the last-sale price as the valuation anchor, the bill reduces ambiguity about which sale sets transaction value in multi-party chains and strengthens CBP’s documentary reach when calculating adjustments—potentially increasing duties collected and the compliance burden on firms that rely on earlier-stage pricing.

What This Bill Actually Does
Customs valuation under the Tariff Act has long relied on the “transaction value” — essentially the price actually paid or payable for the imported goods — but the statute and practice allow room for interpretation when multiple sales occur before goods enter the United States. This bill narrows that ambiguity by instructing that, for a single sale, the transaction value is the price the U.S. buyer pays a foreign seller, and for a series of sales it is the price the U.S. buyer pays in the last sale that brings the goods into the U.S. That means earlier foreign-to-foreign sales will not, under the text, set the transaction value when a subsequent sale introduces the goods into the U.S.
The change matters because many global supply chains involve multiple transfers: manufacturer → regional distributor → importer → U.S. buyer. Under this bill, customs duties would be measured at the transaction where the merchandise is effectively introduced into U.S. commerce, not necessarily at the first cross-border transfer.
That reallocation can increase or decrease duty liabilities depending on which link carries the higher price and can limit arguments that lower upstream prices should define value for duties.Separately, the bill amends the provision on adjustments to make explicit that CBP’s authority to require and examine information for valuation adjustments includes “access to books and records.” Practically, that will be the statutory hook CBP can cite when requesting invoices, contracts, transfer-pricing documentation, and other supporting material used to compute adjustments such as assists, royalties, and packing costs.The statute as drafted is narrow in textual change but wide in practical effect: it reorients valuation to the commercial reality of the U.S. sale and strengthens CBP’s documentary basis for verifying adjustments. The details that will determine day-to-day outcomes — how “introduces the merchandise into the United States” is defined, how related-party or consignment sales are treated, and how CBP exercises its access — are left to implementation and litigation risk if parties test the boundaries.
The Five Things You Need to Know
The bill amends Section 402 of the Tariff Act of 1930 (19 U.S.C. 1401a) by adding a new clause at subsection (b)(4)(C) that defines “sold for exportation to the United States.”, For single-sale transactions the statute will use “the price actually paid or payable by the buyer in the United States to the seller located in another country” as the transaction value.
For chains of sales the statute will use “the price actually paid or payable by the buyer in the United States for the merchandise in the last sale that introduces the merchandise into the United States.”, The bill modifies subsection (h)(5) to specify that valuation adjustments include “access to books and records by U.S. Customs and Border Protection,” giving CBP an explicit statutory basis to demand supporting documents.
The language ties valuation to the last-sale link that introduces goods into U.S. commerce, shifting the legal focal point away from earlier cross-border transfers or upstream prices.

Short title
Provides the Act’s name: the Last Sale Valuation Act of 2026. This is purely titular; it does not change substance but flags legislative intent to focus valuation on the last sale into the United States.
Define ‘sold for exportation to the United States’ to reference the last sale
Adds a new paragraph (C) to subsection (b)(4) with a two-part definition: one line for single-sale transactions and a second line for multi-sale chains that points valuation to the last sale that brings the merchandise into the U.S. Mechanically, customs officials must look to the contractual price paid by the U.S. buyer to establish transaction value; where there are intermediate transfers, customs must identify the sale that first introduces the goods into U.S. commerce and use that price. This provision changes the mapping exercise CBP and importers perform when reconstructing transaction value in complex supply chains.
Explicit CBP access to books and records for valuation adjustments
Inserts language into the flush text following subsection (h)(5)(C) clarifying that valuation adjustments include access to books and records by U.S. Customs and Border Protection. That makes documentary inspection an explicit component of the statutory adjustment process rather than relying solely on regulatory or general examination powers. Practically, this strengthens CBP’s statutory footing when requesting contracts, invoices, transfer pricing files, and other documents used to compute adjustments such as assists and royalties.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- U.S. Customs and Border Protection — Gains a clearer statutory rule for which sale sets transaction value and an explicit statutory basis to demand books and records, improving CBP’s ability to verify declared values and compute adjustments.
- U.S. domestic producers competing with imports — May benefit indirectly if duties rise where earlier-stage pricing understated value, narrowing undervaluation pathways and potentially reducing unfair price advantages.
- U.S.-based buyers/importers who are the last purchaser — Obtain clearer legal footing for valuation tied to the price they actually pay, which can simplify internal valuation calculations when they are the importer of record.
Who Bears the Cost
- Importers that rely on upstream (earlier) foreign sale prices to minimize declared value — Could face higher duties or the need to restructure pricing, and must now document the last-sale transaction more rigorously.
- Foreign manufacturers and intermediate distributors — May face increased document requests and scrutiny from CBP to demonstrate how upstream prices relate (or don’t relate) to the last-sale price into the U.S.
- Customs brokers and trade compliance teams — Will incur additional workload to map sale chains, assemble books-and-records packages for CBP, and defend valuation positions when the last-sale link is contested.
- CBP and other government offices — While CBP benefits legally, the agency may need additional resources to process more documentary examinations and complex chain-of-sale inquiries.
Key Issues
The Core Tension
The bill pits accuracy and enforcement — anchoring duties to the price actually paid by the U.S. buyer and giving CBP clear access to records — against administrability and commercial certainty: measuring value at the last-sale link may better reflect U.S. market reality but creates definitional gaps, shifts burdens onto private actors to document chains, and invites transactional restructuring to avoid higher duties.
The statutory change is compact but raises several implementation and legal questions. First, the phrase “last sale that introduces the merchandise into the United States” will require rules or guidance: does “introduce” mean legal ownership transfer, physical entry, first sale to a U.S. resident, or the U.S. entry declaration?
Variations in commercial practices — consignment, transfers within related parties, transfers into foreign distribution centers, and entries from foreign free trade zones — will complicate identification of the relevant sale. Second, related-party and transfer-pricing arrangements create incentives to restructure chains so that the last-sale price minimizes duties; enforcement will depend on how aggressively CBP interprets substance-over-form and related-party transactions.
On documentary access, the bill’s explicit grant increases CBP’s leverage but raises practical and legal limits: confidentiality and privilege claims over transfer-pricing files, cross-border enforcement of foreign entities’ records, and the administrative burden of large-volume document productions. There is also a potential international law dimension: customs valuation must remain consistent with U.S. WTO obligations (the Customs Valuation Agreement), and a rigid last-sale rule could produce valuation outcomes that are contested in dispute settlement if applied in a way that deviates from valuation principles or discriminates against certain transactions.
Finally, the statute leaves many operative definitions and enforcement procedures to administrative implementation; the absence of clarifying regulatory text will be the locus of most near-term disputes and compliance expense.
