Anti-Dumping & Countervailing Duties on Chinese Goods: The Importer's Guide
Most import costs are knowable before you order — a duty rate, freight, landed cost to the cent. Anti-dumping and countervailing duties are the exception, and they are why an importer occasionally receives a bill larger than everything they bought that year.
They are narrow: most products are covered by nothing, and most importers never touch one. But where an order applies, the rates dwarf ordinary duty, they attach to goods that look unremarkable, and the liability can settle long after you have sold the stock and spent the money.
Said plainly and once: this is practitioner guidance, not legal or customs advice. Anyone with real exposure needs a licensed customs broker and, above a certain size, trade counsel.
1. What AD and CVD are, and why both land on you
They answer two different allegations.
Anti-dumping duty responds to a pricing complaint: that goods are sold into your market below their normal value — broadly, below what comparable goods sell for in the exporter's home market, or below a constructed measure of what they cost to make and sell. The duty closes that gap.
Countervailing duty responds to a subsidy complaint: that production or export of the goods benefited from government support of a kind trade rules treat as countervailable. The duty offsets the benefit.
Both normally also require a finding of injury to a domestic industry, and both can apply to the same goods at once.
The part that catches people is who pays. Neither duty is billed to the Chinese producer or exporter; both are collected from the importer of record — you — at the border, on top of ordinary duty and any China-specific tariff programme. See our 2026 tariffs guide for how the other layers stack.
Rates attach to a producer and exporter combination rather than to a product, so identical items from two factories can carry very different rates. Recovery routes that work for ordinary duty, such as drawback on re-exported goods, are restricted here, so price them as unrecoverable.
2. Scope is written in words, not in codes
This is the single most important idea in this guide, and the one most importers get wrong.
An order does not cover a tariff code. It covers a written product description — the scope — specifying what the goods are made of, how they are constructed, what dimensions, tolerances and finishes they fall within, and what is expressly excluded. Tariff codes usually appear alongside it, and the order will normally state that they are provided for administrative convenience and that the written description governs.
The consequences run both ways:
- A product can be in scope even though its code is not listed. If the goods match the written description, an unlisted code does not save you. It may only mean your entry has not been flagged yet.
- A product can be out of scope despite carrying a listed code. Codes are broad; scopes are narrow. Sitting inside a listed code proves nothing on its own.
Classification and scope are two halves of one problem rather than the same question. Classification decides which heading the goods sit in — our HS code classification guide covers the method. Scope decides whether a remedy reaches those goods, and where that is genuinely unclear the instrument that resolves it is a scope ruling: a formal determination by the investigating authority on whether particular merchandise falls inside a given order.
3. How an order comes into existence
A process, not a timetable — the deadlines are statutory, jurisdiction-specific and not worth memorising.
A petition is filed, usually by a domestic producer or industry association alleging dumping or subsidisation and consequent injury. Authorities can also initiate cases themselves.
The case is investigated. In the United States this is split between two agencies: one examines the pricing or subsidy question, the other injury, and both limbs must be affirmative for a duty to result. The European Commission runs both limbs itself; in the United Kingdom the Trade Remedies Authority investigates and recommends.
A preliminary determination lands. This is the moment that matters commercially, because it is generally where provisional measures begin — customs is instructed to suspend normal settlement of entries and start collecting deposits. Goods already on the water can be caught, and where an authority finds critical circumstances or has ordered imports to be registered, measures can reach back to earlier entries.
Final determinations follow and an order issues. Rates are generally producer- and exporter-specific, with a separate residual rate for exporters that do not participate or cannot demonstrate independence from state control. In China cases that residual category is a live risk, so your rate depends on which entity actually produced and exported the goods.
4. Cash deposits are provisional — the mechanic that ruins importers
If you take one operational point from this guide, take this one.
In the United States the amount your broker pays at entry is a cash deposit, calculated at the rate then in effect for that producer and exporter. It is an estimate. The entry is not settled — liquidation is suspended — and it can stay that way a long time.
Final liability is fixed at administrative review. Interested parties can request a review of a past period; the authority re-examines what the correct rate should have been and instructs customs accordingly. If the reviewed rate lands above your deposit you owe the difference on every affected entry, with interest. If it lands below, you are refunded. Where no review is requested, entries are generally settled at the deposit rate.
That is the whole trap. The importer who checked the rate, paid it in full, cleared cleanly and sold the goods has done nothing wrong and is still exposed, because the number they paid was never final. Bills of this kind arrive long after the fact, at rates that can be multiples of the deposit, against volume that has already shipped — and you cannot re-price stock that no longer exists.
Deposit rates also move during the life of an order, so the rate quoted while you were negotiating may not be the rate at arrival. Check the current instructions, not last year's entry.
The European Union and the United Kingdom generally operate prospectively: duty collected at import is normally the duty owed, with refund and review mechanisms rather than an open-ended later assessment. Know which system your market runs before you model the exposure.
5. Why "the supplier says it's not covered" is worth nothing
Suppliers are asked this constantly, and the answer is almost always reassuring. Treat it as sales copy.
They carry none of the liability. Unless you buy on delivered-duty-paid terms the supplier never sees the bill, and even then the importer of record remains answerable to customs — see our Incoterms guide.
They are not the deciding party. Scope is determined by your customs authority applying the written description, and a supplier assurance carries no evidential weight in an enquiry.
They may be right about the wrong entity. A factory quoting its own favourable rate may not be the exporter on your paperwork, and buying through a trading company can change which rate applies entirely.
Some answers are worse than useless. "We can write a different description on the invoice", "we will use another code", "we ship through a third country so there is no problem" are not workarounds. They are offers to make a false statement to your government, in your name, on your entry — and you are the party who signs for it.
Take from the supplier only what they alone hold: materials, dimensions, construction, and the identity of the actual producer and exporter. Our supplier verification checklist covers establishing who you are really dealing with.
6. Circumvention and transshipment: fraud, not a strategy
Once an order exists, a grey industry grows up around avoiding it, and it is marketed to importers as logistics.
Transshipment — routing Chinese goods through a third country and declaring that country as origin — is not a loophole. It is a false declaration of origin, and where the intent is to evade a trade remedy it is treated as evasion or fraud rather than as a classification dispute. Authorities run dedicated evasion enforcement programmes, act on allegations from competitors and industry bodies, and pursue the importer.
Circumvention is broader and does not require anyone to lie. Minor alterations to a product, later-developed versions of it, or assembly of substantially Chinese inputs in a third country can all be brought inside an existing order through an anti-circumvention proceeding. A supply chain restructured specifically to sit just outside a scope is the fact pattern that invites the proceeding which pulls it back in.
A genuine relocation of manufacturing is a slow, capital-intensive project you can go and inspect — our China vs Vietnam comparison covers what it involves. An arrangement where the price barely moves, the lead time barely moves and only the paperwork changes country is a paper transaction, and your entry carries it.
7. Country of origin decides the real answer
Both the honest and the dishonest versions of the above turn on origin, so be precise about what it means here.
Origin for trade-remedy purposes is a customs determination, not a description of where the last box was sealed or the shipping documents were issued. The governing concept in the United States is substantial transformation: whether processing in a country produced a new and different article with a distinct name, character and use. Simple assembly, packaging, labelling, testing or relabelling generally does not achieve that. Other jurisdictions apply their own tests, often expressed as tariff-heading shifts or value-added thresholds, and the answer is fact-specific everywhere.
Two consequences. Moving final assembly out of China does not by itself move the origin — where the essential character was fixed in China, the origin frequently stays there. And origin for AD/CVD purposes need not line up with the origin you mark on the product or declare for other purposes; these are separate determinations that people conflate constantly. See our country-of-origin marking guide and, for origin in low-value parcel treatment, our de minimis and Section 321 guide.
If a supply chain change is meant to change your duty position, have the origin analysis done properly and in writing before the first container ships.
8. How to check exposure before you place the order
The work is neither long nor expensive. Do it during sampling, not after the deposit is paid, and start from a defensible code — it does not answer the scope question, but it tells you which orders to go and read.
Search the official case listings. Every major market publishes what is in force: the United States lists orders and ongoing proceedings, with customs separately publishing the case-level instructions its officers apply at entry; the European Union expresses measures against the TARIC code; the United Kingdom keeps a public file per case. Search by product terms and not only by code — a scope written in prose is found with the words that describe your goods.
Read the scope against a real specification: materials, dimensions, coatings, tolerances, whether the goods are finished or further worked. Read the exclusions as carefully as the inclusions — scopes are written around a boundary somebody argued hard for. If you are reasoning about whether your product is "really" what the order was aimed at, you are close enough to the line to need advice.
Take advice. A licensed customs broker will tell you whether a category is active and flag the obvious hits. Anything genuinely borderline, or where volume makes the exposure material, is a trade lawyer's question.
Apply for a binding scope ruling. Where the answer is unclear, the authority will decide in advance whether specific merchandise falls inside a specific order — the only route that turns your reading into a position it is committed to. An affirmative ruling is not purely forward-looking: it can reach entries already made and not yet settled, which is an argument for asking early.
Then price the result. Our duty calculator handles the ordinary layers; treat AD/CVD as a separate and much larger line.
9. What to write into the contract
Contract terms are worth having but are not a substitute for the checks above — a judgment against a supplier with no intention of paying is expensive paper. Our purchase order essentials guide covers the wider document; these are the AD/CVD-specific clauses.
Identify the actual producer and exporter by name, and require the shipping documents to match them. Rates attach to entities.
Prohibit substitution without written consent. Subcontracting to another factory, or exporting through a different entity, can change the applicable rate without changing anything visible in the goods.
Warrant origin and country of manufacture, with a commitment to provide the production records, material certificates and process documentation needed to evidence it if customs asks.
Prohibit transshipment and misdescription on invoices, packing lists and certificates, expressly and in terms, so there is no room for a helpful improvisation at the port.
Allocate the cost. State who bears AD/CVD if it is assessed, including retroactively, and back it with a retention or holdback rather than an indemnity alone.
Include a suspension and termination right triggered by the initiation of an investigation or scope inquiry covering the goods, and require record retention and audit access for long enough to cover the review period in your market.
10. Everything here moves
Rates change at every review. Orders are extended, varied and revoked, new investigations are initiated routinely, and a category that is quiet this year is not guaranteed to stay quiet. That is why this guide quotes no rate, no case and no deadline: any specific number would be wrong soon, and a stale number is more dangerous than none, because it gets relied on.
So make it a standing check rather than a one-off. Re-verify scope and rate before each significant order, not once per product. Watch for initiations in your categories, because the preliminary determination is what changes your economics and it arrives faster than a supply chain can be moved. Keep the reasoning you relied on, dated, alongside your classification file, and re-run it whenever the specification, the factory or the exporter changes.
The bottom line
AD/CVD is narrow but severe, and the severity sits in mechanics that are easy to miss. Scope is prose, not a code list, so a clean-looking tariff heading proves nothing. The money paid at entry may be a deposit rather than a settlement, and the final number can arrive years later with interest attached.
Check before you order, get a scope ruling on anything close to the line, write the origin and producer obligations into the contract, and take real advice where volume justifies it — all of it trivial next to one retroactive assessment.
