Frequently Asked Questions
What are the three key elements used to determine the calculation of customs duties payable?
The three key elements are origin, tariff classification, and customs value. Value is particularly critical because most duties are levied “ad valorem,” meaning they are calculated as a percentage of the goods’ value.
How does the WTO Valuation Agreement define the preferred basis for the valuation of goods?
The WTO Valuation Agreement establishes that the basis for valuation should, to the greatest extent possible, be the transaction value of the goods. This system is intended to be fair, uniform, and neutral, precluding the use of arbitrary or fictitious values.
What was the “Brussels Definition of Value” (BDV) and why was it considered insufficient for global harmonization?
The BDV defined value as the price a good would fetch in an open market between an independent buyer and seller. Because it was not applied globally (notably excluding the US), it failed to provide a truly harmonized approach to international trade.
What is the “sequential approach” in customs valuation, and which methods may be reversed in order?
The sequential approach requires customs to attempt valuation using Method 1 through Method 6 in strict numerical order. However, the declarant has the specific right to request that the order of Method 4 (Deductive Method) and Method 5 (Computed Method) be reversed.
Define “price actually paid or payable” (PAPP) in the context of Method 1.
The PAPP is the total payment made or to be made by the buyer to the seller, or to a third party for the seller’s benefit, as a condition of the sale. This includes all direct and indirect payments, even if they differ from the specific invoice value.
Under what circumstances can a buying commission be excluded from the customs value?
A buying commission—the fee paid by an importer to an agent for representing them in a purchase—can be left out of the customs value. This exclusion is only permitted if the payment is shown separately from the price actually paid or payable for the goods.
What are “assists” and how do they affect the transaction value?
Assists are goods or services supplied by the buyer to the seller free of charge or at a reduced cost for use in producing the imported goods, such as materials, tools, or R&D. The value of these assists must be added to the price actually paid or payable to establish the correct customs value.
How do customs authorities determine if a relationship between a buyer and seller has influenced the transaction price?
Customs authorities examine the circumstances of the sale to see if the price is at “arm’s length,” meaning the parties acted independently. Importers can demonstrate this by showing the price is close to “test values” from unrelated transactions or by providing transfer pricing studies.
What is the difference between “identical goods” and “similar goods” for valuation purposes?
Identical goods are the same in all respects, including physical characteristics, quality, and reputation, despite minor appearance differences. Similar goods are not alike in all respects but have like characteristics and component materials that allow them to be commercially interchangeable.
Explain the purpose of the “Release of Goods on Guarantee” provision.
This provision allows importers to take possession of their goods even if the final valuation process is incomplete. By providing a guarantee or surety to cover potential duties, the importer facilitates trade flow while customs ensures future payment.
Customs valuation is one of the most important aspects of international trade compliance.
