If your goods pass through a middleman before reaching the U.S., you may be able to declare the lower manufacturer price for duty purposes — and keep the difference.

You must obtain a binding ruling from U.S. Customs and Border Protection before using First Sale valuation. The ruling process takes 30–60 days and requires documenting your supply chain. Expect $5,000–$15,000 in legal fees.
The economics of First Sale improve significantly when annual duty savings exceed $30,000. Below that threshold, the ruling cost and ongoing compliance burden may outweigh the benefit. High-tariff goods from China or high-volume import programs are the strongest candidates.
The middleman must be a genuinely independent company — not a wholly-owned subsidiary, parent, or affiliate under common control. Related-party transactions can qualify, but require additional transfer pricing documentation and CBP scrutiny.
First Sale valuation is a U.S. Customs and Border Protection (CBP) method that allows importers to declare the price paid in the first transaction in the supply chain — typically the manufacturer-to-middleman (or factory-to-trading-company) price — rather than the higher middleman-to-importer price. Because customs duties are calculated as a percentage of the declared value, a lower First Sale value means lower duties.
Yes. To use First Sale valuation, importers must obtain a binding ruling from U.S. Customs and Border Protection confirming that their specific supply chain qualifies. The ruling process typically takes 30–60 days and requires documentation showing that the first sale was a bona fide sale for export to the United States, the middleman is a separate legal entity, and the manufacturer price is the price actually paid in the first sale. CBP rulings cost approximately $5,000–$15,000 in legal and preparation fees.
To qualify for First Sale valuation, four key conditions must be met: (1) The goods must be sold in a series of transactions — at minimum a manufacturer sale to a middleman and a middleman sale to the U.S. importer. (2) The middleman must be a separate, independent legal entity — not a wholly-owned subsidiary or division of the manufacturer or importer. (3) The first sale must be 'clearly destined for export to the United States' at the time of the transaction. (4) The importer must be able to document the manufacturer price through invoices, contracts, and bank records.
Savings depend on the spread between your manufacturer price and your middleman invoice price, and the tariff rate applied. A typical middleman markup is 10–30% of the manufacturer price. On a $5 million annual import program with a 20% tariff and a 20% middleman markup, First Sale could save approximately $200,000 per year in customs duties. The calculator on this page estimates your specific savings based on your inputs.
First Sale valuation is generally worth pursuing when annual duty savings exceed $30,000, which covers the one-time CBP ruling cost within the first year and provides ongoing annual savings. It is most effective for businesses with high-tariff goods, a clear two-tier supply chain (manufacturer → independent middleman → US importer), and stable, repeating import programs. If your middleman is a related party (parent company, subsidiary, or affiliate), the qualification requirements are more complex and may require additional transfer pricing documentation.
