Question 1

What are the requirements for using first sale for export customs valuation?

Accepted Answer

First sale requires a bona fide arm's-length sale for export to the U.S., documentary evidence including manufacturer invoices and proof of payment, and demonstration that goods were clearly destined for the U.S. at the time of the first sale under 19 U.S.C. § 1401a.

Question 2

What documentation is required to use first sale valuation, and how long do I need to keep it?

Accepted Answer

Required documents include purchase orders, manufacturer-to-middleman invoices, proof of payment, and contracts showing U.S. destination. Records must be retained 5 years under 19 U.S.C. § 1508 and 19 CFR § 163.4.

Question 3

Are there sourcing structures, transaction types, or supply chain arrangements where first sale valuation is difficult or impossible to support?

Accepted Answer

Yes. Single-tier transactions, consignment, intra-company transfers, and toll manufacturing make first sale legally impossible. Related-party first sales face heightened CBP scrutiny under the circumstances-of-sale test.

Question 4

If my supplier is in China but I buy through a Hong Kong trading company, can I use the China factory price as the basis for customs value?

Accepted Answer

Generally no. CBP requires transaction value based on the price paid to your direct seller. You may use the factory price only if the Hong Kong entity is a bona fide buying agent that does not take title to the goods.

Question 5

What are the typical dollar savings when using first sale valuation on imports subject to tariffs?

Accepted Answer

First sale typically reduces dutiable value by 10-50% depending on middleman markup and duty rate. With Section 301 tariffs at 25%, savings on high-volume programs can reach millions annually. Formula: Savings = (Transaction Value - First Sale Price) x Duty Rate x Annual Volume.

Question 6

How do I calculate whether first sale is worth the cost for my import program?

Accepted Answer

Compare potential duty savings against setup costs (typically $25K-$75K in legal fees) and ongoing compliance costs. Programs generating less than $50K-$100K annually are rarely cost-effective. Key factors: middleman markup above 15-20%, high duty rates, and supply chain transparency.

Question 7

Is first sale valuation still legal in the US?

Accepted Answer

Yes. First sale remains legal under 19 U.S.C. § 1401a, established by Nissho Iwai American Corp. v. United States (1982). CBP scrutiny has increased and documentation requirements are rigorous, but the methodology is valid and widely used for high-tariff goods.

Question 8

What costs must still be added to the first sale price when determining customs value?

Accepted Answer

Mandatory additions under 19 USC § 1401a(b)(1) include packing costs, selling commissions, assists (tooling, materials, engineering), royalties, and proceeds of subsequent resale. The U.S. uses FOB valuation so freight and insurance to port of export are generally not added.

Question 9

Does use of first sale valuation affect the country of origin of my imports?

Accepted Answer

No. Valuation and country of origin are separate legal concepts. Origin is determined by substantial transformation under 19 CFR Part 134 regardless of which sale is used for customs value. The middleman's location is irrelevant to origin.

Question 10

What might trigger an audit of an importer's first sale program?

Accepted Answer

Audit triggers include missing documentation, shell-entity middlemen, related-party pricing without arm's-length evidence, sudden shifts in declared value, high-volume entries in high-duty categories, and anomalies in CBP's automated targeting systems.

Question 11

What happens if CBP rejects an importer's use of first sale after it's already been used? Does the importer owe back duties, penalties, or interest?

Accepted Answer

Yes to all three. CBP reliquidates entries and assesses back duties. Interest accrues under 19 USC § 1505(d). Penalties under 19 USC § 1592 range from 2x revenue loss (negligence) to full domestic value (fraud). CBP can reach back up to 5 years.

Question 12

Can first sale valuation be applied to existing suppliers, or is it easier to implement when establishing a new sourcing relationship?

Accepted Answer

Both are possible but new relationships are easier — documentation requirements can be built in from the outset. Existing relationships require retroactive restructuring which can raise CBP red flags and may face middleman resistance to price disclosure.
