Anti-Dumping Duty Rates: What 251 Recent US Determinations Show

Importers search for “anti-dumping duty rates” expecting a table like the tariff schedule. What exists instead is a determination archive: each document sets rates for named companies in one case, and the number that applies to your shipment depends on whether your exporter is named, whether your producer is named, and which review period the entry falls into. The tables below describe that archive rather than replace it — every figure is recomputed from our AD/CVD determination slice at generation time.

Why the rate is three numbers, not one

A single notice usually publishes at least three rates for one product: one for each individually examined exporter, one all-others rate for exporters that were not examined, and sometimes a separate producer rate when the producer and exporter are different companies. On top of that, a cash-deposit rate and a dumping margin are not the same quantity. In the slice, 35 determinations state a cash-deposit rate and 27 state a margin — the rest either cover multiple companies or publish no single percentage at all, which is why only 62 of 251 rows can be summarized as one number per document.

The cash-deposit rate is what CBP collects at entry; the margin is the finding. They usually match, and when they do not it is because of corrections, offsets or a rate that was amended after the order. Liquidation reconciles the two, which means an importer who budgets on the margin rather than the deposit can be surprised at the end of the cycle in either direction.

The distribution of the 62 stated rates

Single stated rates in the slice, banded. Median 23.5%, range 0% to 541.75%.

The shape matters more than the median. A large cluster sits in the 10–25% band, which is where routine findings land; a thin tail runs past 100%, which is where non-cooperative or adverse-facts findings land. 1 determinations in the slice state a rate of exactly zero — a final result at zero usually means the order is revoked or that no deposit is collected from the companies examined, and it is the single most misread number in the archive, because a zero for one exporter is not a zero for the case.

Read these as evidence of how wide the range is, not as a target list. Each rate binds the companies named in its document; the same product from a different exporter in the same country can carry a materially different rate in the same review, because the rate follows the company's own sales and cost data.

Reading a rate table without a lawyer

A determination's rate table is usually a grid: companies down the side, rate types across the top. Three columns do most of the work. The exporter column is who you actually buy from; the producer column is who made the goods; the all-others column is what everyone else in the country pays. If your supplier appears in neither the exporter nor the producer column, the all-others rate is the one that applies — and it is not the average of the named rates, which is the assumption that most often produces a wrong budget. A company that is named but not individually examined can also be assigned a separate rate in the same document, so a name in the table is not the same thing as a name with its own margin.

Where a table lists a range rather than a number, it is usually because the case covers several program countries or several product families in one notice. In that situation the correct reading is per shipment, not per case: the rate follows the specific origin and the specific exporter of the goods in front of you.

Which document type you are reading

The slice spans 251 determinations across 4 action types. A preliminary result sets a provisional cash-deposit rate; a final result usually replaces it; a final order is what makes collection permanent; an amended order changes a number inside an order that already exists. When two documents disagree, the later one governs the later entry window — not because it is more authoritative, but because that is the document CBP's instructions follow.

From a percentage to a dollar figure at entry

A rate only becomes money at the port. The cash deposit is calculated on the entered value of the shipment, not on the invoice total — freight, insurance and the terms of sale decide what the entered value is, so the same rate produces different deposits for the same goods depending on whether they were bought FOB or CIF. Two shipments with identical merchandise can therefore carry different cash-deposit amounts without any rate change at all.

The deposit is also not the final bill. An entry is liquidated later, and liquidation is where the difference between a provisional and a final rate is settled: a deposit collected at a preliminary rate that is later revised produces either a refund or a supplemental bill, plus interest in the second case. Importers who budget from the rate alone tend to be surprised in the cycle after the review, not in the cycle they planned for. The working rule is to budget the deposit as cash flow and the final rate as cost, and to keep them in separate lines rather than averaging them into one number.

Finding the rate you will actually pay

Work from the case, not from the product name. Our AD/CVD case browser indexes the orders by case number, country and product scope, and each case links to the determinations that set its rates. If you do not know the case, classify the goods with the HS code search first and match the scope lines, then read the latest document on the notice feed. Add the result to the MFN rate and any Section 301 action in the duty calculator; the worked arithmetic for a real case is in the calculation example.

Three habits reduce the error rate. Check the scope before the rate, because a precise rate for an out-of-scope product is still the wrong answer. Check the effective date against your entry date rather than today's date. And check whether your supplier is the producer named in the notice — buying through a trading company does not reset the rate that attaches to the goods.
