Anti-Dumping & Countervailing Duties (AD/CVD): The Tariff Most Importers Miss

Most importers know to check MFN duty rates, Section 301 tariffs, and the Section 122 surcharge. Far fewer know to check for anti-dumping (AD) and countervailing (CVD) duties — and that gap catches people off guard more than almost anything else in this business, because AD/CVD rates aren't a flat percentage you can look up once. They're product-specific, exporter-specific, and can run from a few percent to well over 500%.

If you import steel, aluminum, solar panels, furniture, tires, shrimp, or lumber, this is not an optional thing to understand — it's very likely already affecting your landed cost.

Anti-Dumping vs. Countervailing — What's the Difference?

These two are often mentioned together, but they address different problems:

A single product can be — and often is — hit with both at once. It can also carry its normal MFN duty and a Section 301 or Section 232 tariff on top of that. Combined, a Chinese steel product has faced a 25% Section 232 tariff, a 265% AD rate, and a 15% CVD rate simultaneously — over 300% in total duties on the same shipment.

How an AD/CVD Order Gets Created

AD/CVD orders don't come from a general policy announcement — they start with a specific complaint from a US industry, and go through a formal investigation:

1. Petition filed. A US industry group alleges a foreign producer is dumping goods or benefiting from subsidies, and that it's causing them injury.
2. Preliminary determination. Commerce issues a preliminary dumping or subsidy margin. CBP starts collecting cash deposits at that rate immediately — before the case is even finished.
3. Final determination. Both Commerce (rate) and the ITC (injury) issue final rulings. If both are affirmative, a permanent order is published in the Federal Register.
4. Annual reviews. Commerce re-calculates the rate for individual exporters every year. Rates can shift significantly between reviews — sometimes sharply higher.
5. Sunset reviews. Every five years, the order is reviewed to decide whether it should continue.

The rate you pay depends heavily on which specific producer you're buying from. Producers that cooperate fully with the investigation typically get individually calculated, often lower, rates. Producers that don't cooperate — or weren't individually examined — get an "all-others" rate, which is usually the least favorable.

Which Products Get Hit Hardest

AD/CVD orders concentrate heavily in a handful of categories:

• Steel and aluminum products — the single largest category, from wire rod to steel framing to coated sheet
• Solar panels and cells — some of the highest combined rates of any product category
• Furniture — particularly wood and upholstered furniture from certain countries
• Tires — passenger and truck tires have long-running orders
• Shrimp and certain seafood — a recurring target of both AD and CVD orders
• Lumber and wood products — especially softwood lumber

China remains the country most frequently named in AD/CVD orders, followed by India, South Korea, and Taiwan — but orders exist against dozens of countries, so "not from China" doesn't automatically mean you're clear.

How to Check If You're Affected

1. Search the ITC and Commerce case databases for active orders matching your product category and country of origin.
2. Identify the exact producer, not just the country. Rates are assigned per exporter — the same product from two different factories in the same country can carry very different rates.
3. Check CBP's ACE portal for the current cash deposit rate tied to the specific AD/CVD case number.
4. Request a scope ruling from Commerce if you're not sure whether your specific product falls within an order's technical description — these rulings are common because product scope language can be surprisingly narrow or broad.
5. Build in a contingency. A common practice is setting aside 10–20% above the estimated duty deposit, since rates can be revised after preliminary determinations.

What Importers Can Actually Do

AD/CVD duties are a fact of life for certain product categories — but importers aren't entirely powerless against them:

• Participate in administrative reviews to argue for a lower rate on your specific transactions
• Request a scope ruling if you believe your product isn't actually covered by the order's technical language
• File a changed circumstances review if market conditions have shifted meaningfully since the order was issued
• Compare sourcing countries — the same product from a country with no active order can have a dramatically lower total landed cost
• Never attempt to evade an order through transshipment or misclassification — CBP actively investigates evasion, and the penalties are severe. If you suspect a supplier is doing this on your behalf, that exposure lands on you as the importer of record.
