First Sale Rule for Apparel Imports: How It Cuts US Duty

First sale rule for apparel imports lets US importers in multi-tier deals declare the factory-to-middleman price rather than their own purchase price, if strict tests are met. Because apparel duty is ad valorem, often 10–32% plus any extra tariffs, a lower value can cut duty on every shipment.

US apparel duty is high compared with many products, and many brands now also pay additional tariffs on clothing from some countries. Every percentage point of customs value matters. Many apparel brands buy through a trading company, vendor or agent rather than directly from the factory. If that is your set-up, the first sale rule may let you declare a lower, earlier price as the customs value, and lawfully reduce duty. This guide explains the rule with a worked example, then gives an eligibility checklist. It is general information, not legal advice; work with a licensed customs broker or trade lawyer before using first sale.

What is the first sale rule for apparel imports?

The first sale rule for apparel imports is a US customs valuation approach that lets an importer in a multi-tier transaction declare the price of an earlier sale, usually from the factory to a middleman, rather than the importer's own purchase price. It applies only if the earlier sale is bona fide, at arm's length and for goods clearly destined for the US. Because apparel duty is ad valorem, often around 10–32%, a lower value lowers duty.

How does a multi-tier apparel transaction work?

In a simple deal, you buy directly from the factory, and that price is the transaction value. In a multi-tier deal, the factory sells to a middleman, such as a trading company or vendor, which then sells to you at a higher price. US customs usually values goods on your price, the last sale. The first sale rule, confirmed by a US court decision known as Nissho Iwai in 1992 and reflected in customs practice, allows the earlier factory price to be used if conditions are met.

If additional ad valorem tariffs apply to the same value, the saving grows with them. The saving is proportional to the middleman's margin, so programs with larger margins and larger volumes gain more.

Eligibility checklist

Use this checklist with your broker or lawyer.

1. Is there a real multi-tier transaction? There must be a sale from the factory to the middleman and a separate sale from the middleman to you.
2. Is the first sale bona fide? The middleman must take title and risk, not just act as a buying agent passing through costs.
3. Is it at arm's length? If factory and middleman are related, you must show the price was not influenced by the relationship.
4. Were the goods clearly destined for the US? At the time of the first sale, evidence such as US labels, US-specific purchase orders or US size charts should show the goods were made for the US market.
5. Can you document it? You need both invoices, payment proof and transaction flow records.

Why is documentation the hardest part?

The middleman must share its factory price with you and customs, which reveals its margin. Many trading companies are reluctant. Some agree under confidentiality arrangements or through a third-party reviewer. You need the factory invoice, the middleman's invoice, purchase orders for both sales, payment records, a flow chart of goods and money, and evidence of US destination. Keep records for at least five years. Our how to write a purchase order for clothing production guide explains which PO details help.

First sale vs last sale valuation: which option fits?

The table compares the two approaches on selection criteria.

The trade-offs are duty savings against documentation effort and supplier cooperation. First sale usually makes sense for larger programs with a meaningful middleman margin and willing suppliers. Small brands buying directly from factories already pay on the factory price.

How does first sale interact with tariffs on China?

Section 301 duties and other ad valorem tariffs on goods from some countries are generally calculated on the same customs value, so a valid first sale value usually lowers them too. Tariff rules changed several times in 2025, so check current rules with your broker. Our US tariffs on clothing imports from China guide explains the current tariff landscape.

How does first sale compare with other cost levers?

First sale is one lever among several. Others include choosing the correct tariff classification, using free trade agreement origin, shifting origin to another country, or changing incoterms. Our apparel manufacturing cost and pricing hub covers these levers. Always compare total landed cost, not duty alone.

How do you set up a first sale program?

1. Map your supply chain and identify middlemen.
2. Estimate potential savings from margin and volume.
3. Ask suppliers if they will share factory invoices.
4. Have a broker or lawyer review eligibility.
5. Build a documentation package for each program.
6. Declare first sale on entries as advised and keep records.

When is first sale not worth pursuing?

First sale is not always worth the effort. If you buy directly from the factory, there is no earlier sale to use. If the middleman's margin is small, the saving may not cover legal and documentation costs. If your supplier will not share factory invoices, you cannot support the claim. If the factory and middleman are related and pricing cannot be shown to be at arm's length, the claim may fail. And if your volumes are small, the effort may outweigh the benefit. In those cases, other levers, such as better classification, a different origin or direct factory buying, may deliver more. Our payment terms for clothing manufacturers guide explains how buying directly can change both cost and risk.

What happens in a customs audit?

US Customs and Border Protection can request documents to support a first sale claim. If documents are missing or the tests are not met, customs may reject the lower value and assess additional duty, and possibly penalties. A clear documentation package for each program, reviewed before declaring first sale, reduces this risk.

Common mistakes with the first sale rule

• Using first sale with a buying agent instead of a real seller.
• Declaring first sale without the factory invoice.
• Ignoring related-party pricing tests.
• Failing to show US destination at the time of the first sale.
• Assuming the EU allows the same approach.
