The Tariff Surprise That Has Blindsided Thousands of Importers
Of all the customs compliance risks, anti-dumping (AD) and countervailing duty (CVD) orders are among the most dangerous for importers who are unaware of them. Unlike regular tariffs, AD/CVD rates can reach 200%, 400%, or even 1,000% of the goods' value. Importers who discover an applicable AD/CVD order after their goods have been imported may face bills for retroactive duties that can bankrupt a business.
This guide explains how AD/CVD orders work, what triggers them, and most importantly, how to check whether your product is subject to an order before you commit to importing.
What Is Dumping?
Dumping occurs when a foreign company sells products in the US at a price below the price it charges in its home market (or below its cost of production). Under US trade law (the Tariff Act of 1930 as amended), dumping is actionable when it causes or threatens to cause material injury to a US domestic industry.
The anti-dumping process is initiated by US domestic producers who believe they are being harmed by dumped imports. They file a petition jointly with the:
- US Department of Commerce (DOC), which investigates whether dumping is occurring and by how much (the dumping margin)
- US International Trade Commission (ITC), which investigates whether the domestic industry is materially injured by the dumped imports
If both agencies make affirmative findings, Commerce issues an anti-dumping duty order imposing additional duties equal to the calculated dumping margin.
What Are Countervailing Duties?
Countervailing duties (CVDs) address a different problem: government subsidies to foreign producers. If a foreign government provides grants, low-interest loans, tax breaks, or other subsidies to producers of a specific product, US producers who compete with those subsidized imports can petition for CVD relief. Commerce investigates the subsidy rate, and if injury is found, CVD orders impose additional duties equal to the net subsidy rate.
China is the most common target of CVD orders because its state-owned enterprises and state-directed economy create numerous countervailable subsidy programs.
How AD/CVD Rates Are Set
AD/CVD rates are company-specific and reviewed annually. The rate assigned to a specific Chinese manufacturer reflects the calculated dumping or subsidy margin for that company. Companies not individually investigated are assigned an "all-others" or "China-wide" rate, which is typically higher than individually calculated rates.
Key point: rates change every year through the annual review process. An importer who knew the rate for their Chinese supplier last year may face a dramatically different rate this year if the supplier's rate was revised upward in a subsequent review.
How to Check for AD/CVD Orders
The most important step before committing to any import is to check whether your product and country of origin are subject to an AD/CVD order. There are two primary resources:
1. CBP's ACE/ADCVD Portal
CBP maintains an online searchable database of all active AD/CVD orders at cbp.gov/trade/priority-issues/adcvd. Search by HTS code or product description to find applicable orders.
2. Commerce's ITA AD/CVD Searchable Database
The International Trade Administration maintains a comprehensive database of orders, scope rulings, and current cash deposit rates at access.trade.gov. You can search by country, product, or HTS code.
Major Product Categories with AD/CVD Orders
Hundreds of products from dozens of countries are subject to AD/CVD orders. Major categories affecting Chinese imports include:
- Steel products (hot-rolled, cold-rolled, plate, pipe, wire rod, rebar)
- Aluminum extrusions
- Solar panels and solar cells
- Tires (passenger, light truck, OTR)
- Wooden furniture and cabinets
- Shrimp and honey
- Ceramic tile and floor tile
- Paper and paperboard products
- Chemical precursors and industrial chemicals
The "Scope" Question: Is Your Product Covered?
AD/CVD orders include a "scope" that defines exactly what products are covered. Products just outside the scope are not subject to the order; products within the scope are. Scope determinations can be fact-intensive and legally complex.
If you believe your product might be at the scope boundary, you can request a scope ruling from Commerce, which will issue a binding determination on whether your specific product falls within the order's scope. This is strongly recommended before importing significant volumes of a borderline product.
Reimbursement Prohibition
One often-overlooked rule: AD law prohibits the US importer from being reimbursed for anti-dumping duties by the foreign exporter. If CBP determines that a foreign supplier reimbursed its US buyer for AD duties — whether directly or through price adjustments — the dumping margin can be doubled as a penalty.
Bottom Line
Anti-dumping and countervailing duty orders are a separate and potentially catastrophic layer of import cost that exists entirely independently of regular tariff rates. Always check for AD/CVD orders before importing. Use our HTS code lookup to identify your product's classification, then cross-reference with CBP's and Commerce's AD/CVD databases. When in doubt, consult a customs broker or trade attorney before placing your first order.
