Information date: 2 November 2026 — MOFCOM’s Trade Remedy Bureau publishes every anti-dumping and countervailing case — initiation, preliminary and final determination, undertaking, interim review, expiry review, new-shipper review — on trb.mofcom.gov.cn. That page is an index, not a duty calculator. The operative number sits in the final determination announcement: a company-specific margin for each named exporter or producer, a rate for cooperating but non-sampled firms, and a countrywide residual rate for everyone else. Chinese customs collects the anti-dumping duty deposit at the moment of import declaration, at the rate tied to the producer named on the invoice, packing list and certificate of origin. Two containers under the same HS code can therefore clear the same day at very different deposit rates, and the broker withholds the higher figure until the mill of origin is documented. If your supplier is a named cooperating exporter, budget the named rate and keep the mill certificate on file for every shipment. If the supplier is unnamed or newly built, assume the residual rate for pricing until a new-shipper review concludes, and treat any lower broker quote as provisional. If the product scope is arguable, obtain a written scope analysis before the first declaration rather than after a deposit is withheld. Where the measure is close to expiry, check whether an expiry review has been initiated, because that determines whether the deposit continues next quarter.

MOFCOM’s Trade Remedy Bureau publishes every anti-dumping and countervailing case — initiation, preliminary and final determination, undertaking, interim review, expiry review, new-shipper review — on trb.mofcom.gov.cn.

Scope has to be fixed before the numbers mean anything: Relevant to any importer of record, exporting manufacturer or contract manufacturer whose product falls under an HS line carrying a Chinese trade-remedy measure: certain steel products, chemicals, polysilicon, fasteners, some food and agricultural lines. Before relying on any rate, confirm five things: the exact product-scope wording in the announcement, including model types and exclusions; whether your counterparty appears by name in the annex; whether an interim, expiry or new-shipper review has changed the rate since the original determination; whether the goods enter under general trade, processing trade or bonded logistics, because deposit mechanics differ; and which HS code customs will actually apply at declaration. Anything outside that set is a separate question with its own evidence requirement, and mixing the two is the most common way a workable plan turns into an unusable one.
For a decision on “Resources: Where to Check Whether an Anti-Dumping or Countervailing Duty Hits Your Product — MOFCOM Case Look-Up, Company-Specific Rates and the Deposit a Broker Withholds”, keep three layers apart: the published rule or statistic, the company’s own orders and process records, and the assumptions nobody has tested yet. The first layer defines the external conditions, the second proves what is true for this business, and the third is where the risk actually sits. Public material cannot substitute for a contract, a system log, a sample or a live test.
A practical way to test the scope is to ask which parts of “Resources: Where to Check Whether an Anti-Dumping or Countervailing Duty Hits Your Product — MOFCOM Case Look-Up, Company-Specific Rates and the Deposit a Broker Withholds” would still be true if the company changed supplier, entity or product line tomorrow. Items that survive that change belong to the rule layer and can be taken from official publications; items that do not survive belong to the operating layer and have to be rebuilt from invoices, warehouse records, customs entries or platform statements.

How the effect reaches operations
China opens a case on a MOFCOM investigation establishing dumping margin, injury to the domestic industry and causal link, then hands collection to customs. Duty is levied as a deposit on entry and later settled as final duty, with refund or top-up. Rates are exporter-specific because margins are computed from each sampled company’s export price against normal value, while non-cooperating exporters receive a facts-available rate, usually the highest. Because liability attaches to the producer rather than the importer, a shipment routed through a trader that cannot document the mill of origin defaults to the residual rate. Reviews reset rates periodically, so a rate sheet more than a year old is the single most common cause of overpayment or of an unbudgeted assessment after clearance.
The classic error is treating the case title in the look-up as the applicable rate. A second is assuming a supplier’s self-declared margin is binding when only the annex matters. A third is ignoring scope language: measures often cover ‘certain’ widths, grades or thicknesses, and a nearby product is outside. Anti-dumping and countervailing duties can stack on the same entry, and a countervailing case can be opened years after the anti-dumping one. Importers also forget that an expiry review usually keeps the measure alive during the review, and that processing-trade and bonded entries have separate deposit rules that a broker may apply inconsistently across ports.
Translated into an operating sequence, China opens a case on a MOFCOM investigation establishing dumping margin, injury to the domestic industry and causal link, then hands collection to customs. Duty is levied as a deposit on entry and later settled as final duty, with refund or top-up. Rates are exporter-specific because margins are computed from each sampled company’s export price against normal value, while non-cooperating exporters receive a facts-available rate, usually the highest. Because liability attaches to the producer rather than the importer, a shipment routed through a trader that cannot document the mill of origin defaults to the residual rate. Reviews reset rates periodically, so a rate sheet more than a year old is the single most common cause of overpayment or of an unbudgeted assessment after clearance. That ordering matters: check applicability first, then the transmission step, and only then the size of the gap in cost or timing. When an intermediate step cannot be confirmed, the honest response is to narrow the scope of the conclusion rather than to substitute an industry average for the company’s own figures.
The cost of getting the order wrong is asymmetric. A team that checks applicability too late usually discovers it at the point where the shipment, the filing or the invoice can no longer be changed without penalty, and by then the only remaining lever is price. A team that checks early spends a few hours on questions that turn out to be irrelevant, which is cheap by comparison. On “Resources: Where to Check Whether an Anti-Dumping or Countervailing Duty Hits Your Product — MOFCOM Case Look-Up, Company-Specific Rates and the Deposit a Broker Withholds” the practical rule is therefore to spend the first hour on scope and the second on the numbers, never the other way round.
Decision
If your supplier is a named cooperating exporter, budget the named rate and keep the mill certificate on file for every shipment. If the supplier is unnamed or newly built, assume the residual rate for pricing until a new-shipper review concludes, and treat any lower broker quote as provisional. If the product scope is arguable, obtain a written scope analysis before the first declaration rather than after a deposit is withheld. Where the measure is close to expiry, check whether an expiry review has been initiated, because that determines whether the deposit continues next quarter.
The conditions should be written down so the decision can be re-run by someone else: Relevant to any importer of record, exporting manufacturer or contract manufacturer whose product falls under an HS line carrying a Chinese trade-remedy measure: certain steel products, chemicals, polysilicon, fasteners, some food and agricultural lines. Before relying on any rate, confirm five things: the exact product-scope wording in the announcement, including model types and exclusions; whether your counterparty appears by name in the annex; whether an interim, expiry or new-shipper review has changed the rate since the original determination; whether the goods enter under general trade, processing trade or bonded logistics, because deposit mechanics differ; and which HS code customs will actually apply at declaration. When those hold, proceed as described; when one is missing, close the gap first and decide afterwards.

Two workstreams usually have to move in parallel. The compliance workstream closes the document side of “Resources: Where to Check Whether an Anti-Dumping or Countervailing Duty Hits Your Product — MOFCOM Case Look-Up, Company-Specific Rates and the Deposit a Broker Withholds” — registrations, confirmations, filings — while the commercial workstream protects the delivery date, the pricing already quoted and the customer commitments that were made on the earlier reading of the rules. Running them as one queue is how small documentation gaps become missed shipment dates: the commercial side waits for a certificate that could have been requested a week earlier. If your supplier is a named cooperating exporter, budget the named rate and keep the mill certificate on file for every shipment. If the supplier is unnamed or newly built, assume the residual rate for pricing until a new-shipper review concludes, and treat any lower broker quote as provisional. If the product scope is arguable, obtain a written scope analysis before the first declaration rather than after a deposit is withheld. Where the measure is close to expiry, check whether an expiry review has been initiated, because that determines whether the deposit continues next quarter. Set one owner per workstream and one shared status sheet, and treat a red item on either side as a reason to freeze only the affected order.
Implementation checklist
- Pull the final determination annex and match your producer name exactly.
- Require mill-of-origin documents with every shipment before booking.
- Re-check the case status quarterly for reviews and expiry notices.
- Name one decision owner, one execution owner and one review date.
- Keep the source page, access date, entity and internal evidence.
- On any change, reopen only the affected judgement.
Evidence and review
Start with the smallest test that can change the answer: Pull the final determination annex and match your producer name exactly. Pick one real entity or one representative case, write down the continue, watch and stop conditions in advance, and record the input version, the owner, the start time and the actual result. The first pass should only look at facts that move the decision; formatting preferences are not risk.
The second pass is completed by “Require mill-of-origin documents with every shipment before booking”, and someone who did not prepare the file should spot-check one piece of critical evidence. The classic error is treating the case title in the look-up as the applicable rate. A second is assuming a supplier’s self-declared margin is binding when only the annex matters. A third is ignoring scope language: measures often cover ‘certain’ widths, grades or thicknesses, and a nearby product is outside. Anti-dumping and countervailing duties can stack on the same entry, and a countervailing case can be opened years after the anti-dumping one. Importers also forget that an expiry review usually keeps the measure alive during the review, and that processing-trade and bonded entries have separate deposit rules that a broker may apply inconsistently across ports. A single small deviation can be corrected in place; a repeated deviation, or one that touches a statutory duty or changes the economics, is what justifies pausing the affected part.
After “Re-check the case status quarterly for reviews and expiry notices”, compare the actual result with the baseline rather than with the impression of the team. If your supplier is a named cooperating exporter, budget the named rate and keep the mill certificate on file for every shipment. If the supplier is unnamed or newly built, assume the residual rate for pricing until a new-shipper review concludes, and treat any lower broker quote as provisional. If the product scope is arguable, obtain a written scope analysis before the first declaration rather than after a deposit is withheld. Where the measure is close to expiry, check whether an expiry review has been initiated, because that determines whether the deposit continues next quarter. When the arrangement is extended to more products, customers or processes, keep the same success test and one complete record per batch. If later information changes, update only the affected fields.
One last discipline keeps the file usable next quarter: write the closing note as if a colleague who has never spoken to the supplier has to act on it. That note states what was verified, on which date, against which source, and what remains open — on “Resources: Where to Check Whether an Anti-Dumping or Countervailing Duty Hits Your Product — MOFCOM Case Look-Up, Company-Specific Rates and the Deposit a Broker Withholds” it also states which of the three actions was actually finished and which was only scheduled. Teams that skip the closing note re-litigate the same question every month, and each round costs more than the documentation would have. This is a research roadmap for compliance planning, not a legal opinion on classification, scope or duty liability. Rates, scope and review status change with each announcement, and port practice on deposits varies.

The limits are structural rather than cautious wording.
