Antidumping and Countervailing Duties: A Complete US Importer's Guide

Antidumping (AD) and countervailing duty (CVD) orders represent some of the most significant cost increases an importer can face. Unlike tariffs set by trade policy, AD/CVD duties are trade remedies designed to offset unfair foreign pricing or government subsidies. Rates can be staggering: some AD/CVD orders impose combined duties exceeding 200-300% of the product's value. For importers, failing to identify an active AD/CVD order before placing a purchase order can turn a profitable transaction into a catastrophic loss. This guide explains how AD/CVD duties work, how to check for active orders, and how to build compliance into your sourcing strategy.

How Antidumping Duties Work

Antidumping duties are imposed when the US Department of Commerce determines that a foreign producer is selling goods in the US market at less than fair value, meaning the export price is lower than the normal value (typically the price in the home market or a constructed cost of production). The process begins when a US domestic industry files a petition with both the Department of Commerce and the International Trade Commission (ITC). Commerce investigates the pricing, while the ITC determines whether the domestic industry is materially injured by the dumped imports. If both agencies reach affirmative determinations, an antidumping duty order is issued.

The AD duty rate is calculated as the difference between the normal value and the export price, expressed as a percentage. Individual foreign producers who cooperate with the investigation receive company-specific rates. Producers who do not cooperate, or who are not individually examined, receive a higher "all others" rate or an adverse facts available (AFA) rate that can be punishingly high. These rates are not static. Commerce conducts annual administrative reviews where importers and foreign producers can request updated rate calculations based on actual transaction data.

How Countervailing Duties Work

Countervailing duties offset foreign government subsidies that benefit exporters. These subsidies can take many forms: direct cash grants, tax exemptions, below-market loans, discounted raw materials from state-owned enterprises, or preferential energy pricing. Commerce investigates the subsidy programs and calculates a CVD rate that represents the net benefit the foreign producer receives from the subsidies, expressed as a percentage of the export price. Like AD duties, CVD orders require an affirmative injury determination from the ITC. A single product can be subject to both AD and CVD orders simultaneously, and the rates are cumulative.

How to Check for Active AD/CVD Orders

The most important step any importer can take is to check for active AD/CVD orders before sourcing a product. The primary resources for this research are the Department of Commerce's Enforcement and Compliance website and the ITC's AD/CVD database. Commerce maintains a comprehensive list of all active AD/CVD orders, organized by country and product. The ITC's database allows searches by HTS code, country, and product description. Both are publicly available and free to use.

1. Identify your product's correct HTS classification. AD/CVD orders are defined by scope language, not HTS codes alone, but the HTS code is the starting point for identifying potentially applicable orders.
2. Search the ITC AD/CVD database (https://www.usitc.gov/trade_remedy/orders/) using your HTS code and the country of origin.
3. Read the scope language of any potentially applicable order carefully. The scope defines exactly which products are covered, often with detailed specifications regarding dimensions, chemistry, end use, or production process.
4. If your product appears to fall within scope, identify the applicable duty rate. Check Commerce's Federal Register notices for current rates from the most recent administrative review.
5. Consider requesting a scope ruling from Commerce if there is ambiguity about whether your product is covered. A scope ruling provides binding certainty.

Understanding Scope Language

The scope of an AD/CVD order is the legal definition of which products are covered. Scope language can be extremely detailed, specifying physical characteristics, chemical compositions, manufacturing processes, and end uses. It can also be surprisingly broad. For example, the AD/CVD orders on Chinese steel nails cover "certain steel nails" but then define that term to include a vast range of nail types, sizes, and finishes. Understanding scope language is a specialized skill, and misinterpretation can be costly. If you believe your product is close to but outside the scope of an order, you should strongly consider requesting a formal scope ruling from Commerce or consulting with a trade attorney.

Common Scope Pitfalls

• Assuming that a different HTS code means your product is not covered. Scope language controls, not the HTS code.
• Relying on the product name rather than the technical specifications. An order on 'certain circular welded pipe' may cover products you would call tubes or conduit.
• Ignoring scope expansions. Commerce can and does expand the scope of existing orders to cover products that were being used to circumvent the original order.
• Assuming that minor modifications take your product out of scope. Adding a coating, changing a dimension, or performing minimal further processing often does not change scope coverage.
• Failing to check for new orders. Commerce initiates new AD/CVD investigations regularly. A product that was duty-free last year could be subject to a new order this year.

The Administrative Review Process

AD/CVD duty rates are not permanent. Each year, Commerce conducts administrative reviews of active orders. During these reviews, importers and foreign producers can submit actual transaction data to calculate updated duty rates. The review process typically takes 12-18 months. Until a review is completed, importers deposit duties at the rate from the most recent completed review (or the original investigation rate if no review has been completed). After the review, Commerce issues final rates, and importers either receive refunds for overpayments or must pay additional duties for underpayments. This liquidation process creates significant financial uncertainty for importers, as the final duty rate may differ substantially from the deposit rate.

Evasion Enforcement: EAPA Investigations

The Enforce and Protect Act (EAPA) of 2015 gave CBP powerful tools to investigate and penalize AD/CVD evasion. EAPA investigations can be initiated by domestic producers, other interested parties, or CBP itself. Common evasion schemes include transshipment through third countries, misclassification to avoid covered HTS codes, undervaluation of declared customs value, and misrepresentation of country of origin. CBP has significantly increased EAPA investigations in recent years, with a focus on Chinese goods being routed through Southeast Asian countries. The penalties for evasion include assessment of all evaded duties plus interest, civil penalties, and potential criminal prosecution.
