What are anti-dumping and countervailing duties?

Anti-dumping (AD) and countervailing duties (CVD) are trade-remedy duties imposed on certain imported products. They are intended to address unfair foreign pricing or government support that harms a domestic industry.

These duties are separate from ordinary customs duties and from other trade measures, such as:

• Section 301 measures, which generally address specified trade practices or policy concerns.
• Section 232 measures, which generally address national-security concerns.

A product may be subject to more than one type of measure at the same time.

What is dumping?

Dumping occurs when a foreign producer or exporter sells a product in the importing country at less than its normal value. Normal value may be based on the price in the producer’s home market, a constructed value, or another legally permitted comparison.

The basic comparison is between:

• The product’s export price or constructed export price; and
• Its normal value.

A finding of dumping does not, by itself, mean that a company violated a criminal law. In trade-remedy proceedings, the relevant question is whether the pricing meets the legal standard for dumping and whether the dumped imports injure, or threaten to injure, a domestic industry.

What are unfair subsidies?

A countervailable subsidy is a financial contribution or other benefit provided by a foreign government or public entity to a producer, exporter, or industry. Examples can include:

• Grants or direct financial support
• Preferential loans or loan guarantees
• Tax benefits
• Government-provided goods or services at favorable terms
• Access to land, energy, or other inputs on terms that provide a benefit

Not every government program is automatically countervailable. The program must meet the applicable legal requirements, including requirements concerning the nature and availability of the benefit.

CVD proceedings examine the benefit attributable to the imported product and whether the subsidized imports injure, or threaten to injure, a domestic industry.

How AD and CVD proceedings work

In the United States, the Department of Commerce generally determines whether dumping or countervailable subsidies exist and calculates the applicable rate. The U.S. International Trade Commission generally determines whether the domestic industry has suffered the required injury or threat.

If the agencies make the required findings, an AD or CVD order may be issued. The order identifies the covered products and countries and provides instructions for import entry and duty collection.

The order’s product description—often called the scope—is especially important. An HTS classification can help identify potentially covered merchandise, but the written scope generally controls if there is a conflict between the tariff number and the product description.

Why can AD/CVD rates be very high?

AD and CVD rates are not ordinary tariff rates. They are calculated from case-specific findings and can be substantially higher than the standard customs duty.

Rates may be high because of factors such as:

• A large difference between export price and normal value
• Significant government benefits attributed to the product
• Multiple subsidy programs
• The use of adverse facts available when a company does not provide required information
• Differences between preliminary and final determinations
• Later administrative reviews or other proceedings

An advertised rate is not necessarily the final amount that will apply to every shipment. The applicable rate can depend on the producer, exporter, period of entry, administrative-review results, and other case details.

Why rates can be company-specific

An AD or CVD order may list different rates for different companies. This happens because the agencies may examine individual producers or exporters and calculate their results separately.

A shipment can therefore require more than the product description and country of origin. A merchant may also need to identify:

• The actual manufacturer or producer
• The exporter or seller
• The relationship between the parties
• Whether the company has its own assigned rate
• Whether the company is covered by an “all others” or residual rate
• Whether the producer-exporter combination matches the information used for entry

Using a company-specific rate for the wrong company can result in incorrect duty payment, entry corrections, or later liability. Importers should obtain professional customs advice when the manufacturer or exporter information is incomplete or the case treatment is unclear.

Product-and-country specific coverage

AD/CVD duties apply to defined products from defined countries. They do not automatically apply to every product in a category, every product from a region, or every product shipped through a named country.

Coverage usually depends on several facts:

• The product’s physical characteristics and intended use
• The manufacturing process and materials
• The country of production or origin
• The producer and exporter
• The applicable order and its scope language
• The entry date and any relevant proceeding or review
• Whether an exclusion or scope ruling applies

The country of origin is generally more important than the country from which the goods were shipped. For example, routing merchandise through a third country does not necessarily change its origin or remove it from an AD/CVD order.

An HTS number is useful for screening, but it is not a guarantee of coverage or noncoverage. The same HTS provision can contain both covered and non-covered merchandise, and covered merchandise can sometimes be entered under more than one tariff classification.

How a merchant checks whether a product is covered

Use a structured review rather than relying on an HTS number alone.

1. Gather complete product information

Before searching, collect:

• A detailed product description
• Product composition and specifications
• Dimensions, model numbers, and technical characteristics
• Intended use
• Country where the product was manufactured
• Manufacturer, producer, and exporter names
• Supplier and commercial-invoice information
• Likely HTS classification

If the product is private-label merchandise, identify the factory that actually produces it. The brand owner or seller may not be the relevant producer for AD/CVD purposes.

2. Confirm the likely HTS classification

Search a product or HTS code or browse the HTS tree to identify possible tariff provisions.

Treat the result as a starting point. Classification tools may identify related measures, but the written AD/CVD scope and the product facts determine whether the order applies.

3. Check the country of origin

Review measures by country of origin for the relevant country. Replace the example country with the actual country of production.

Also consider whether processing in another country changes the legal origin. Origin analysis can be fact-specific, particularly where assembly, substantial transformation, or multiple production stages are involved.

4. Read the order scope

Look for the full scope description, including:

• Included product characteristics
• Excluded products
• Product names and commercial descriptions
• Physical dimensions or material requirements
• Covered processing or finishing
• Explicit exclusions
• Relevant notes concerning tariff classifications

Do not rely only on a search result, a supplier’s statement, or a general product label. If the facts are close to the scope boundary, a formal scope inquiry or legal review may be appropriate.

5. Check the producer and exporter

Compare the actual parties to the companies listed in the order or related agency information. Confirm whether:

• The producer has an individually calculated rate
• The exporter has a separate rate
• The producer-exporter combination matters
• The company is subject to an all-others or residual rate
• A rate changed in a later administrative review

A supplier may not know its AD/CVD treatment, and a marketplace listing usually does not provide enough information to determine the correct rate.

6. Check current information

AD/CVD cases can change through investigations, final determinations, administrative reviews, scope rulings, sunset reviews, and liquidation instructions. Review all tracked measures and recent changes as screening tools, then verify the current legal information through the relevant government source.

For a live import transaction, confirm:

• Whether the order is currently in effect
• The applicable rate for the relevant company
• Whether the entry falls within the relevant period
• Whether cash deposits or other entry requirements apply
• Whether later assessment could differ from the initial deposit

How AD/CVD duties are collected

AD/CVD amounts are commonly collected through a cash deposit at entry. The deposit is not always the final duty liability. Later proceedings can establish the final assessment rate for entries from a particular period.

This creates two practical risks:

• The importer may owe more after a later review.
• The importer may need to pursue a refund or other adjustment if the final rate is lower.

Importers of record remain responsible for accurate entry information and payment, even when a supplier, broker, marketplace, or fulfillment provider supplied the product data.

Do not confuse AD/CVD with Section 301 or Section 232

AD/CVD, Section 301, and Section 232 are different trade measures with different legal bases and coverage rules.

A product can be covered by AD/CVD and also be subject to Section 301 or Section 232. Check each measure independently rather than assuming one result answers all tariff questions.

Practical compliance checklist

Before importing a product that may be subject to trade remedies:

• Classify the product as accurately as possible.
• Identify the true country of origin.
• Obtain the actual producer and exporter names.
• Search SkuWatch’s product and HTS tools.
• Review the relevant country page and measure database.
• Read the order’s written scope.
• Check company-specific rates and later reviews.
• Check recent changes before entry.
• Have a customs broker or trade counsel review ambiguous cases.
• Keep product specifications, origin records, supplier declarations, and rate-supporting documents.

The absence of a result in a screening tool is not a legal determination that the merchandise is excluded. When product facts are close to an order’s scope, professional advice or a formal government ruling may be necessary.

Frequently asked questions

Are AD/CVD duties the same as normal customs duties?

No. Normal customs duties generally come from the tariff schedule. AD/CVD duties result from trade-remedy proceedings and can have separate scope rules, rates, and entry requirements.

Does an HTS code determine whether AD/CVD applies?

No. An HTS code is an important screening tool, but the written scope of the AD/CVD order controls. Product characteristics, origin, producer, exporter, and other case facts may determine coverage.

Why might two suppliers selling the same product have different AD/CVD rates?

Rates can be company-specific. Different producers or exporters may have been investigated separately, assigned different rates, or placed under different review results. The correct rate may depend on the particular producer-exporter combination.

Can a product be subject to AD/CVD and Section 301 or Section 232 at the same time?

Yes. These measures are legally separate and can apply cumulatively. Check Section 301, Section 232, and AD/CVD coverage independently.
