The First Sale Rule: How Florida Importers Legally Lower Customs Value in 2026

The first sale rule lets a U.S. importer declare the price the factory charged the middleman, rather than the higher price the middleman charged the importer. In a multi-tier transaction, that lower value becomes the dutiable value, and duty is assessed on it. For Florida importers buying through trading companies in Asia or Latin America, the savings are often 5–20% of duty spend — and the rule is fully legal when the paperwork supports it.

What the first sale rule actually is

U.S. customs value is normally “transaction value” — the price actually paid or payable for goods sold for export to the United States. When goods pass through two or more sales before arriving (factory → trading company → U.S. importer), there is more than one candidate price. The first sale rule, established in Nissho Iwai American Corp. v. United States, allows the earlier sale to be used as the basis for appraisement.

Duty is a percentage of declared value, so lowering the declared value lowers the duty. With tariff rates elevated on many categories, the arithmetic matters more than it did a decade ago.

The three conditions you must meet

CBP will accept a first sale valuation only if the importer can demonstrate all three of the following:

1. A bona fide sale for export to the United States

The first transaction must be a genuine sale — title and risk of loss must pass from the factory to the middleman. A consignment arrangement or an intercompany transfer that is not a real sale will not qualify.

2. Goods clearly destined for the U.S. at the time of the first sale

There must be objective evidence that the goods were earmarked for the United States when the factory sold them. U.S.-specific labeling, UL or FDA markings, purchase orders referencing a U.S. consignee, and production records all help establish this.

3. An arm’s-length price unaffected by relationship

If the factory and the middleman are related parties, you must show the price was not influenced by the relationship — typically through a transfer pricing study or by showing the price covers all costs plus a profit consistent with the industry.

What documentation CBP expects

This is where most first sale programs fail. You need the factory’s commercial invoice to the middleman, proof of payment on that invoice, the purchase order chain, and evidence of the U.S. destination. A middleman that refuses to disclose its factory cost is a practical dead end — and that refusal is common, because it exposes the middleman’s margin.

Keep these records for five years from the date of entry. If CBP issues a CF-28 Request for Information and you cannot produce the first sale documentation, the entry gets re-appraised at the higher value with interest, and potentially penalties under 19 U.S.C. 1592. Our overview of single entry vs. continuous customs bonds explains the financial exposure behind those adjustments.

When first sale is worth the effort

First sale programs carry real setup cost — legal review, supplier negotiation, and often a binding ruling request. The break-even is usually meaningful import volume through a middleman on dutiable goods. If your goods enter duty-free under a trade program, there is nothing to save; see USMCA and CAFTA-DR duty-free basics first. If your goods are already sourced direct from the factory, there is no second sale to skip.

Many Miami importers pair first sale with duty deferral. Holding goods in a bonded warehouse postpones the duty payment; first sale reduces the amount owed when it finally comes due. The two strategies stack.

Getting a binding ruling

If the structure is complex or the amounts are large, request a binding ruling from CBP’s National Commodity Specialist Division before you start filing. A ruling gives you certainty and a defensible position in an audit. Work with a licensed customs broker or trade attorney on the submission — our breakdown of who does what among forwarders, 3PLs, and customs brokers clarifies which partner owns which piece.

Frequently asked questions

Is the first sale rule legal?

Yes. The first sale rule is an accepted method of customs appraisement under U.S. law, upheld in federal court and recognized by CBP. It is not a loophole, but it does require documentation proving the first sale qualifies.

How much duty can the first sale rule save?

Savings depend on the middleman’s markup and your duty rate. If a trading company adds 15% and your goods carry a 10% duty rate, you save roughly 1.5% of the invoice value on every shipment. Higher tariff rates increase the savings proportionally.

What happens if CBP rejects my first sale claim?

CBP will re-appraise the entry at the higher transaction value and bill the duty difference plus interest. If CBP finds the claim was negligent or fraudulent, penalties under 19 U.S.C. 1592 can apply on top of the duty owed.
