Anti-Dumping Duty Notification: How to Read the Notice That Sets Your Rate

Short answer: An anti-dumping duty notification is the Federal Register document that records a determination for one named case and one named scope. It is where the cash-deposit rate, the effective date and the product scope are published together. To read it you need five fields — case number, publication date, effective date, the rate table, and the scope language — and nothing else on the page changes what you pay.

A notification is not a notice that a duty exists somewhere in the abstract; it is the instrument that switches a rate on for entries made on a stated date. Our own copy of the Federal Register carries 300 notices published between 2026-09-01 and 2026-10-28, of which 211 mention anti-dumping or countervailing duty in the title or abstract. 208 of the whole window were filed by the Department of Commerce, 82 by the International Trade Commission. Every figure on this page is recomputed from that mirror and from our AD/CVD determination slice at generation time.

What an anti-dumping duty notification actually is

Two agencies put anti-dumping machinery into the Federal Register, and they publish different things. Commerce (through the International Trade Administration) publishes the investigation and review results: the dumping margin it calculated, the cash-deposit rate that follows from it, the all-others rate for exporters that were not individually examined. The ITC publishes the injury side: whether a domestic industry is materially injured, and the five-year sunset reviews that decide whether an order survives. A notification from one agency can be read on its own, but the rate you pay is only complete once both halves have landed, because Commerce cannot order collection until the ITC has found injury.

Practically this means the same case number appears several times across a year, and each appearance is a separate notification with its own document number and its own effective date. Importers who search for “the” notification for their product usually find an older one and take a superseded rate to their broker. The date on the notice, not the date of your search, decides which one applies to an entry.

The five fields that decide what you pay

Read in this order: scope first, rate second. A rate quoted from a notice whose scope does not reach your product is a misreading, not a discount.

Four notice types that move a rate

Not every notification changes what you pay. Some announce that something has started, some that a number has changed, and some that the case is over. Our AD/CVD slice of 251 determinations covering 2026-08-06 through 2026-11-03 breaks down by action type as follows — the same vocabulary a notification uses in its own title.

Determinations by action type, recomputed from data/adcv_cases.json.

A preliminary result sets a provisional rate and starts cash-deposit collection in most reviews; a final result usually replaces it, and the difference is collected or refunded at liquidation. A final order is the instrument that makes the case permanent, and an amended order corrects a rate, a scope line or a company name inside an order that already exists. A sunset review decides whether the order continues for another five years, and a revocation ends it — the only notice type that removes a rate entirely.

Reading the rate: 62 of 251 determinations carry a single number

Of the determinations in the slice, only 62 state one unambiguous percentage, because a review that covers five exporters publishes five rates and cannot be collapsed into one figure without inventing one. Across those 62, the median rate is 23.50% and the range runs from 0.00% to 541.75%. 35 of them are stated as cash-deposit rates and 27 as dumping margins — a distinction worth watching, because a margin is the finding and a cash-deposit rate is what actually gets collected at the border, and the two can differ after corrections.

Find your notification in sixty seconds

Start from the case number if you have one: our AD/CVD case browser indexes orders by case number, country and product scope, so a case page links to the notices that created and amended it. If you do not have a case number, go the other way: classify the product first with the HS code search (six digits is enough to narrow the candidate cases), then read the case scope lines that match, then check the Federal Register notice feed for the latest document on that case. Finally, put the whole stack — MFN rate plus anti-dumping plus any Section 301 action — through the duty calculator so the number you carry to your broker is a total, not a component.

Two shortcuts that save the most time in practice. First, search the document number, not the product name: product names in notices are written in tariff language (“certain cold-rolled steel flat products”) and will not match the words on a commercial invoice. Second, when a notice names both a producer and an exporter, read the rate table by the exporter that appears on your commercial documents, because the producer's rate does not travel with the goods.

What an anti-dumping duty notification is not

It is not a classification ruling: nothing in it tells you which HTS code your product takes, and a scope that names products by description still requires you to classify. It is not retroactive beyond the period it states — entries made before the effective date are governed by whatever was in force then. It is not a substitute for the order itself when you need the full scope history, since amendments rewrite parts of the scope without restating it. And it is not a customs decision you can rely on for future entries: the rate in a preliminary result can move by hundreds of percentage points at the final result, which is why brokers re-read the notice before every entry window rather than keeping last quarter's number.

What is an anti-dumping duty notification?

It is the Federal Register document that publishes one determination for one AD/CVD case: the case number, the rates by exporter, the effective date and the product scope. It is the instrument that switches a cash-deposit rate on for entries made on or after its stated date.

Where do I find the notification for my product?

Use the case number (A-###-### or C-###-###) in our trade-remedies case browser, or classify the product to six digits with the HS code search and match the case scope lines, then read the latest document on the Federal Register notice feed.

Does a notification tell me the total duty I will pay?

No. It publishes only the anti-dumping or countervailing component. The total is the MFN rate from the HTS plus that component plus any Section 301 or Section 232 action that reaches the same HTS line.

Why do two notices for the same case show different rates?

Preliminary and final results are separate notifications, and a final result usually replaces the provisional rate. Amended orders can also change a rate after the order exists, so the newest document on the case is the one that governs the current entry window.

How many AD/CVD notices does ExportSonar mirror?

211 of the 300 Federal Register notices in our current window (2026-09-01 to 2026-10-28) concern anti-dumping or countervailing duty; the whole mirror is available through the notice feed.

What is the difference between a margin and a cash-deposit rate?

The margin is the dumping finding calculated in the review; the cash-deposit rate is what CBP collects at entry. They are usually the same number, but corrections and offsets can make them differ, and liquidation reconciles the two.
