First Sale Valuation Consulting: Using an Earlier Transaction Price to Reduce Your Customs Duties

Introduction: Paying Duty on the Right Price

When goods pass through multiple intermediaries before reaching the U.S. importer, each transaction adds a markup. Under the default customs valuation rules, duties are assessed on the final transaction value: the price the U.S. importer pays to the foreign seller. But if there is an earlier sale in the supply chain, that earlier sale price may be used as the basis for duty calculation under the first sale rule.

The first sale rule is not a loophole or a gray area. It is an established and legally sanctioned valuation method upheld by the Court of Appeals for the Federal Circuit. For importers who purchase goods through multi-tier supply chains, first sale can reduce the dutiable value by 10 to 30 percent or more.

Despite its clear legal foundation and significant financial impact, first sale valuation remains underutilized. Many importers are unaware of the option, and the documentation requirements are perceived as burdensome.

How First Sale Valuation Works

When goods move through a multi-tier supply chain, there are two or more transaction values. The first sale is the price from the factory to the middleman. The last sale is the price from the middleman to the U.S. importer. Under the default rule, duties are assessed on the last sale, which is higher because it includes the middleman’s markup.

The first sale rule allows the importer to use the factory’s price as the basis for duty calculation. For example, if a factory sells goods to a trading company for $10 per unit and the trading company sells them to the U.S. importer for $15, the standard valuation would assess duties on $15. Under first sale, duties are assessed on $10, a 33 percent reduction in dutiable value.

Requirements for a Valid First Sale

The first sale must be a bona fide sale with genuine transfer of ownership. The goods must be clearly destined for the United States at the time of the first sale. The transaction must be arm’s-length, and the documentation must be transparent and complete, including first sale invoices and proof of payment between the factory and middleman.

Implementing a First Sale Program

Begin with a feasibility assessment identifying products that move through multi-tier supply chains. Gather the required documentation including first sale invoices, evidence of payment, and proof of U.S. destination. Work with your customs broker to implement first sale valuation on entries, and maintain the program with updated documentation for each shipment.
