Is your product hit by an AD/CVD order?
Type a product name or HTS code. If it falls under an active anti-dumping or countervailing order, you find out now — not when customs sends the bill.
The duty that catches importers off guard
A normal customs duty is predictable — it lives in the HTS schedule and you can look it up. Section 301 tariffs are also public, currently running 25–100% on many Chinese goods after the four-year review increases that took effect through January 2026.
AD/CVD is different. Each order comes out of a specific case filed by a US industry, applies to a narrow set of products and countries, and carries a rate set by the Department of Commerce that can dwarf everything else. A product that looks like a clean 3.2% duty can turn into a 200% bill because it falls under a dumping order you never checked.
The worst part: the charge typically shows up after the goods arrive. By then the shipment has already sailed, the inventory is committed, and the margin is gone.

Common questions
What is an AD/CVD order?
An anti-dumping duty (AD) or countervailing duty (CVD) order is imposed by the US Department of Commerce when a foreign product is sold below fair value or subsidized. These duties stack on top of the normal customs duty and the Section 301 tariff, and the rates are often far higher — sometimes several hundred percent of the product value.
How much can an AD/CVD rate be?
It varies by case and country. Some rates are in the single digits, but many run 50%, 100%, or higher. The hardwood plywood case against China, for example, has carried rates well above 100%. Importers often find out about the bill only when customs demands payment, long after the goods have shipped.
How is AD/CVD different from Section 301?
Section 301 tariffs (currently 25–100% on many Chinese goods) are a trade-policy measure. AD/CVD orders are case-specific findings of dumping or subsidization, each tied to particular products and countries. A single shipment can carry base duty + Section 301 + AD/CVD all at once.
How do I check if my product is affected?
Type the product name or HTS code above. CVDar matches it against the 397 active AD/CVD orders compiled from Federal Register filings and shows the case, country, and applicable rate before you commit to the order.
