First sale for export: the middleman margin US importers can leave out
Same container, two dutiable values
A factory in Dongguan makes kitchen appliances. It does not sell to you directly: a Hong Kong trading company buys the goods for $400,000 and resells them for $460,000. One container goes to your US distribution arm; an identical one goes to your UK subsidiary. Same factory, same vessel as far as Singapore.
At Long Beach, CBP can accept $400,000 as the dutiable value — the factory price. At Felixstowe, HMRC taxes the price paid by the UK buyer, plus freight. The middleman's $60,000 margin escapes duty in one country and carries it in the other.
Nothing improper is going on. The gap comes from a question the WTO Valuation Agreement leaves open: in a chain of successive sales, which one is the sale "for export to the country of importation"? The United States answers the first, if you can prove it. Most of the world answers the last.
A question the WTO Agreement does not settle
Article 1 of the Agreement anchors transaction value on the price of goods "sold for export to the country of importation". With one sale between factory and importer, that is simple. With a trading house, a sourcing company or a regional hub in between, there are two or three sales, and each can claim the title.
The WTO Technical Committee on Customs Valuation acknowledged the ambiguity in its Commentary 22.1: the Agreement mandates neither the first nor the last sale, and each member chooses. Both readings comply. They simply produce different bases, and the difference is exactly the intermediaries' margin.
That makes first sale unusual. Unlike buying commissions, which follow one rule worldwide, the answer here depends entirely on where the goods land.

The US test: three conditions, all on paper
The doctrine rests on Nissho Iwai American Corp. v. United States (Fed. Cir. 1992), later applied in Synergy Sport International v. United States (CIT 1993). The factory-to-middleman price can be the transaction value when the sale is bona fide, made for export to the United States, and at arm's length.
Bona fide sale means title and risk of loss actually pass to the middleman. A trading house that never owns the goods is not a buyer, and there is no first sale to point to. Destined for the US means the destination is identifiable when the factory order is placed: US plugs and voltage, FCC or UL marking, English-language US packaging, the end customer named on production documents. Generic stock that a middleman warehouses and later allocates across markets fails here. Arm's length is assumed between unrelated parties; if the factory and middleman share an owner, you must show the relationship did not shape the price, using the logic set out in our piece on transfer pricing and customs value.
The binding constraint is usually commercial: the middleman must disclose the factory invoice, which means revealing its margin. Many will not.
The doctrine has survived one serious challenge. In January 2008, CBP published a proposal to interpret "sold for export" as the last sale. Importers pushed back, and Congress responded in the Food, Conservation, and Energy Act of 2008 by barring the change for a period and requiring importers to report when they used first sale, so the practice could be studied. CBP did not revive the proposal. The lesson for importers is that the rule is stable, but it is watched: a first-sale entry stands out, and the file behind it should be ready before the first request arrives.
What a defensible first-sale file contains
CBP rarely questions the principle; it questions the evidence. A file that survives a CF-28 typically holds, per shipment:
- the purchase order from the middleman to the factory, referencing the US buyer or US-specific specifications;
- the factory invoice to the middleman and proof that the middleman paid it, ideally by bank transfer matching the invoice;
- the sale contract or terms showing when title and risk of loss passed to the middleman;
- the middleman's invoice to the importer, so the two prices can be reconciled line by line;
- where factory and middleman are related, an analysis of the circumstances of sale or test values.
Two habits make the difference. Line items must match across both invoices — a factory invoice in cartons and a middleman invoice in pieces invites a rejection. And any assist, royalty or packing cost the importer supplies is still added to the first-sale price, exactly as it would be to the last; first sale removes a margin, not the rest of the valuation statute.
Why UK and EU entities cannot copy it
A group often assumes the US structure can be rolled out across its import entities. It cannot. The UK retained the EU's last-sale wording when it rebuilt its valuation rules after Brexit, and the EU itself closed first sale on 1 May 2016, when Article 128 of Implementing Regulation 2015/2447 replaced the old Article 147 approach; a transitional window for older contracts ended on 31 December 2017. On the same $60,000 margin, a UK entity at a 12% rate (a working assumption) pays $7,200 — roughly £5,700 at $1.27 to the pound — more per container than its US sister, and no paperwork changes that. The only lawful lever in London or Rotterdam is structural: turn the trading house into a genuine buying agent paid a separately invoiced fee.
Three worked cases
1. China-origin appliances into the US. MFN rate of 7.5% and a Section 301 rate of 25% used as working assumptions — verify your actual HTSUS line and list. Both duties sit on the same entered value, as explained in our Section 301 guide.
Factory price to middleman = $400,000; middleman price to you = $460,000
Last-sale duty = 32.5% x 460,000 = $149,500
First-sale duty = 32.5% x 400,000 = $130,000
Saving per entry = $19,500, plus HMF of 0.125% x 60,000 = $75
The merchandise processing fee is likely at its per-entry cap on both bases, so it yields nothing here.
2. The claim that failed on destination. A US importer declared first sale for two years on a $2,000,000 annual margin. On audit, CBP found the middleman bought generic stock and allocated it to buyers in several countries after production.
Margin wrongly excluded = $2,000,000 per year
Loss of revenue = 32.5% x 2,000,000 = $650,000 per year
Two years audited = $1,300,000, before interest
Negligence exposure under 19 U.S.C. § 1592 = up to 2x that loss
3. India, where the middleman margin stays in. An importer buys Korean components through a Singapore trader. Basic customs duty of 10% used as a working assumption.
Trader margin inside CIF value = INR 3,000,000
BCD on that margin = 10% x 3,000,000 = INR 300,000
Social welfare surcharge = 10% of BCD = INR 30,000
Cost per shipment = INR 330,000 — IGST cascades but is creditable

First sale is won or lost before the goods are made. The destination evidence has to exist at the factory order, the middleman has to agree to disclosure in its supply contract, and title has to pass in the right sequence. Retrofitting the paperwork during a CF-28 is rarely convincing. For groups shipping the same product to the US and to Europe, expect two different valuation files for one supply chain — and a US saving that UK and EU entities cannot copy.
Frequently asked questions
Is first sale a loophole CBP merely tolerates?+
No. It is settled case law. In Nissho Iwai American Corp. v. United States (Fed. Cir. 1992), the court held that the price paid by a middleman to the manufacturer can be the transaction value when that sale is bona fide, made for export to the United States and at arm's length. CBP proposed reverting to a last-sale rule in 2008; Congress responded through the Food, Conservation, and Energy Act of 2008, which barred the change and required importers to report use of the rule for a period. The doctrine has stood since.
What documents does CBP expect to see?+
Typically the full chain: the purchase order from the middleman to the factory, the factory invoice to the middleman, proof of payment of that invoice, the middleman's invoice to you, and evidence that title and risk passed to the middleman. Destination evidence matters as much — US labelling, US-specific product standards, the end customer named on production documents. If the factory and the middleman are related, add an analysis showing the relationship did not influence the price, along the lines used for transfer pricing.
Does first sale reduce Section 301 duties too?+
Yes, in most cases. Section 301 duties on Chinese-origin goods are ad valorem and assessed on the same entered value as the MFN duty, so excluding the middleman margin lowers both. That is why first sale gained traction after 2018. It does not change origin: a first sale structure cannot turn Chinese goods into non-Chinese goods, and transshipment arguments are a separate, much riskier matter.
Can I use first sale for goods entering the UK or India?+
No. The UK carried the EU last-sale rule into its post-Brexit valuation regime under the Taxation (Cross-border Trade) Act 2018, so the sale to the UK buyer is the one that counts. Indian practice under the Customs Valuation Rules 2007 assesses the price paid by the Indian importer, and there is no domestic doctrine comparable to Nissho Iwai. In both markets, the only lawful way to keep a sourcing intermediary's reward out of the base is to restructure it as a genuine buying agency.
What if the middleman refuses to show me the factory invoice?+
Then first sale is not available, because you cannot declare a value you cannot evidence. Some middlemen agree to send the factory documents directly to the customs broker under a confidentiality undertaking, so the importer never sees the margin. Others accept a contractual audit right exercisable only by an independent firm. If neither is acceptable, the commercial question becomes whether the duty saving is worth switching to a supplier willing to disclose.
