AD/CVD Duties: What Importers Need to Know

Most importers think about duty as a percentage in the low single digits. Antidumping and countervailing duties are a different order of magnitude — rates in the hundreds of percent are not unusual, and in some cases the duty exceeds the value of the goods several times over.

What makes them genuinely dangerous is not the rate. It is that the amount you pay at entry is provisional, the final amount can be set years later, and it applies retroactively to entries you made long ago.

What the two duties address

Antidumping duty (AD) applies when foreign goods are sold into the U.S. below fair value — below what they sell for in the home market or below cost of production. The duty is intended to offset that margin. It is generally company-specific: two exporters in the same country can have very different rates.

Countervailing duty (CVD) applies when a foreign government subsidizes production, and offsets the subsidy. It is also typically company-specific.

Both come from a two-agency process. The U.S. Department of Commerce determines whether dumping or subsidization occurred and calculates rates; the U.S. International Trade Commission determines whether a U.S. industry is injured. Both must find in the affirmative for an order to issue. CBP then collects.

Scope is where importers get caught

An AD/CVD order covers a described class of merchandise from specified countries. That description — the scope — is the operative text, and it does not map neatly onto HTS codes.

This is the central trap. Two things follow from it:

• Your HTS code does not determine coverage. The scope language does. HTS numbers appear in orders “for convenience only” and are explicitly not dispositive. A product can fall within scope while classified under a number not listed.
• Scope is often broader than the obvious product. Orders frequently extend to downstream and assembled articles containing the covered material. Importers of finished goods regularly discover they are importing a covered product because of what is inside it.

If coverage is genuinely unclear, you can request a formal scope ruling from Commerce. It takes time, but it produces a binding answer, and it is far cheaper than being wrong at scale. Getting the underlying classification right is a prerequisite either way — see our HTS classification guide.

Why your cash deposit is not your final bill

This is the mechanic that surprises even experienced importers.

When you enter goods subject to an order, you pay a cash deposit at the rate in effect that day. That is an estimate. The actual duty is determined later, through an administrative review covering that period of entries — a process that commonly concludes a year or more after the entries were made.

If the reviewed rate is higher than your deposit, you owe the difference, with interest, on entries that shipped, sold and were invoiced to your customers long ago. There is no practical way to pass that cost on retroactively. Importers have been put out of business by exactly this.

Two consequences worth acting on:

1. Do not treat the deposit rate as your landed cost. If you are pricing on a 20% deposit and the review lands at 90%, your margin was never real.
2. Watch your supplier’s specific rate. Rates are assigned to producer–exporter combinations. Changing suppliers within the same country can move you from a favorable rate to the punitive country-wide rate.

Evasion enforcement and the transshipment trap

Because the rates are so high, evasion schemes are common — and enforcement against them is aggressive. The Enforce and Protect Act (EAPA) gives CBP a formal process to investigate allegations of AD/CVD evasion, and those investigations can be initiated by your competitors.

The classic scheme is transshipment: covered goods shipped through a third country, relabeled, and entered as originating there. Importers get caught up in this without intending to, because a broker or supplier offered a “solution” to a duty problem.

Warning signs worth treating seriously:

• A supplier offering to route goods through a third country to reduce duty
• Prices dramatically below every other quote for the same product
• A supplier that will not identify the actual manufacturer
• An invoice that describes the goods vaguely or inaccurately
• Any proposal to change the declared description or origin rather than the sourcing

Remember that the importer of record carries the liability here — not the supplier who suggested it and not the broker who filed it.

Practical steps before you buy

1. Check for orders before placing the purchase order. Commerce and the ITC publish active orders and ongoing investigations. Search by product and country early, while you can still change the decision.
2. Identify the actual producer, not just the trading company, and check that producer’s specific rate.
3. Read the scope language yourself, not a summary. Pay attention to clauses covering downstream and assembled products.
4. Request a scope ruling if you are near a boundary.
5. Model the worst case. Price against a plausible upside rate, not the current deposit.
6. Review your bond. AD/CVD exposure can push you past your continuous bond’s sufficiency, which triggers a required increase.
7. Keep records for five years — origin documentation, mill certificates, production records. Reviews and EAPA investigations ask for them long after the fact.

Does a bonded warehouse help?

Partly, and it is worth being precise. Storing goods in a bonded warehouse defers duty until the goods are withdrawn for consumption, which helps cash flow and gives you time to decide what to do. Goods exported directly from bond without entering U.S. commerce generally do not incur the duty at all — relevant if you are serving Latin American or Caribbean markets from Miami rather than the U.S. market.

What it does not do is change whether a product is within scope. Deferral is timing, not exemption. And if the goods are eventually entered for consumption, the duty applies at the rate then in effect. Our bonded warehouse cost guide and duty drawback guide cover the related mechanics.

Frequently asked questions

How do I know if my product is subject to AD/CVD?

Check the active orders published by the Department of Commerce and the International Trade Commission for your product and country of origin, and read the scope language rather than relying on the HTS numbers listed. If coverage is unclear, request a formal scope ruling from Commerce.

Is the AD/CVD rate I pay at entry final?

No. Entry payments are cash deposits based on the rate in effect that day. The final rate is set in a later administrative review, often more than a year afterward, and any shortfall is billed retroactively with interest.

Does an AD/CVD order apply to finished goods containing a covered material?

It can. Many orders extend to downstream or assembled articles containing the covered merchandise. This is a frequent source of unexpected liability for importers of finished products, which is why reading the full scope text matters.

General information only, not legal advice. AD/CVD orders, rates and procedures change frequently — consult a licensed customs broker or trade attorney before relying on any of this for a specific shipment.
