Antidumping Cash Deposit Rate vs Assessment Rate: Managing the Gap

Key Points

• The U.S. antidumping duty system is retrospective: the cash deposit rate paid at entry is a deposit only, and the true liability is not determined until Commerce completes an administrative review under 19 CFR Part 351.
• Final assessed rates can be substantially higher or lower than the deposit rate, sometimes by tens of percentage points, creating real balance-sheet exposure that can persist for one to three years after importation.
• Administrative reviews are initiated annually and cover entries made during a specific period of review; importers and foreign producers both have the right to request a review, but failure to request one can result in automatic liquidation at the deposit rate.
• Importers should set aside a reserve for potential underpayments as soon as subject merchandise enters, and should track the status of each administrative review period that covers their entries.
• When an entry liquidates at a rate higher than the deposit, CBP issues a bill for the difference plus interest; importers have a limited window to protest before that liability becomes final.

When a U.S. importer buys subject merchandise covered by an antidumping duty order, the cash deposit rate collected at the time of entry is not the final amount owed. Under the U.S. retrospective system, Commerce sets a final assessed rate after reviewing actual transaction data, which can be significantly higher or lower than the deposit. The difference, sometimes called "the gap," represents real financial exposure that must be tracked and reserved for until each entry liquidates.

How the U.S. Retrospective Antidumping System Works

Most countries that impose antidumping duties use a prospective system: the duty rate is set in advance and that rate is what importers pay, full stop. The United States uses a retrospective system, which works differently in a fundamental way.

Under the U.S. approach, when Commerce publishes an antidumping duty order, it simultaneously establishes cash deposit rates for known foreign producers and exporters. These rates are based on the dumping margins calculated during the original investigation. Importers pay those rates as a cash deposit at the time of entry, essentially as a security against future liability.

The actual duty liability is determined later, after Commerce conducts an administrative review of the real prices and costs during the period of review. Only when that review is complete and its results are published does Commerce instruct CBP to liquidate the entries at the final assessed rate. Until liquidation, the importer's true liability is unknown.

This lag, often one to three years between entry and liquidation, is the defining feature of the retrospective system and the source of the gap that importers must manage.

Why Cash Deposit Rates and Assessment Rates Diverge

The deposit rate and the final assessed rate are calculated using different data at different points in time. Several factors drive the divergence.

Different pricing periods

The deposit rate is based on pricing data from the original investigation or the most recent prior review. The final assessed rate is based on actual sale prices and costs during the specific period of review being examined, which may reflect very different market conditions.

New shipper reviews and company-specific rates

A foreign exporter that was not individually examined during the original investigation may be assigned a "all-others" rate at entry. If that exporter is later individually reviewed and found to have a much higher or lower dumping margin, the assessed rate for all entries from that exporter during the review period will reflect the new, company-specific result.

Changes in production costs and pricing behavior

If a foreign producer changes its pricing, product mix, or cost structure during the period of review, Commerce's margin calculation can shift substantially. A producer that was dumping at 20% in the original investigation might be found to have dumped at 60% during the review period, or at 0%.

The "all-others" and country-wide rate problem

Importers sourcing from exporters that are not individually examined often rely on the "all-others" rate as a deposit, but that rate may not be a reliable predictor of the final assessed rate for any individual exporter.

The Administrative Review Process Under 19 CFR Part 351

The administrative review is the formal mechanism by which Commerce determines final assessed rates. The governing regulations are found at 19 CFR Part 351, administered by the Department of Commerce's International Trade Administration.

Annual anniversary month

Each antidumping order has an anniversary month, typically the month the order was published in the Federal Register. Commerce publishes a notice each month listing the orders for which interested parties may request a review. The request window is generally limited to that anniversary month.

Who can request a review

Domestic producers (petitioners), foreign exporters or producers, and U.S. importers of record are all eligible to request an administrative review. Requesting a review is consequential: if no party requests a review for a particular exporter, Commerce will instruct CBP to liquidate that exporter's entries at the existing cash deposit rate, which may lock in a rate that is either favorable or unfavorable.

Timeline from review to liquidation

After the review period closes, Commerce issues a preliminary results notice, followed by a final results notice in the Federal Register. CBP then liquidates covered entries at the final assessed rate. The process typically takes 12 to 18 months from the end of the period of review, though extensions are common. Importers should monitor the Federal Register for preliminary and final results affecting their entries.

Judicial challenges and suspension of liquidation

Parties may challenge final results in the Court of International Trade. When a challenge is filed, Commerce may instruct CBP to suspend liquidation of entries pending the court's decision. This can extend the period of uncertainty by several additional years.

Liquidation, Billing, and Interest on Underpayments

Once Commerce instructs CBP to liquidate entries at the final assessed rate, several things happen in sequence.

How CBP collects underpayments

If the final assessed rate exceeds the cash deposit rate, CBP issues a bill to the importer of record for the difference. That bill includes interest, calculated from the date of liquidation. The interest rate is set by statute and applied to the unpaid duty balance.

Overpayments and refunds

If the assessed rate is lower than the deposit rate, CBP refunds the excess to the importer, also with interest. Importers sometimes overlook the possibility of refunds, particularly when a foreign producer's dumping margin is substantially reduced or eliminated in a review.

Protesting a liquidation

If an importer believes CBP has liquidated an entry incorrectly, the importer may file a protest. The deadline for filing is limited, and missing it forfeits the right to challenge that liquidation. Importers should have a process in place to monitor liquidation notices in ACE and act promptly. See our guide on calculating total landed cost for how AD/CVD exposure should be factored into duty-inclusive cost modeling.

Reserving for the Gap on the Balance Sheet

Because final liability is unknown at the time of entry, importers that source subject merchandise carry a contingent liability on their balance sheets from the date of entry until final liquidation. Managing this reserve accurately is a finance and compliance function, not merely an accounting formality.

Estimating the reserve

A reasonable starting point is to monitor the trend of administrative review results for the specific exporters you source from. If a supplier's margins have been moving upward across successive reviews, reserving at a rate above the current deposit is prudent. If margins have been consistently low or declining, a smaller reserve may be appropriate. The historical review results are published in the Federal Register and are publicly available.

Entry-level tracking

Because each entry is liquidated individually and assigned a rate based on the period of review it falls into, importers need entry-level tracking, not just aggregate estimates. A spreadsheet or compliance platform that maps each entry to its period of review, the applicable exporter, and the current status of the review for that period gives finance teams the visibility they need to maintain an accurate accrual.

Currency and cost implications

The gap between deposit and assessed rates can be large enough to turn a profitable import program into an unprofitable one after liquidation. Sourcing decisions should incorporate a scenario analysis that models the impact of assessed rates ranging from the current deposit to plausible higher outcomes based on review history.

Communication with suppliers

Some import contracts include provisions that shift the risk of antidumping duty increases to the foreign supplier. Whether such provisions are enforceable and commercially practical depends on the specific relationship, but they are worth considering when negotiating supply agreements for subject merchandise.

What Importers Should Do

• Map every entry to its period of review. For each antidumping order covering your imports, identify which administrative review period applies to each entry, monitor the Federal Register for preliminary and final results, and note when Commerce instructs CBP to liquidate.
• Establish a balance-sheet reserve at entry. Work with your finance team to set an accrual based on the gap between the deposit rate and a defensible estimate of the likely assessed rate, updated as review results are published.
• Request administrative reviews when warranted. If your supplier believes its actual dumping margin is lower than the deposit rate, coordinate with the foreign producer to ensure a timely review request is filed during the anniversary month. Missing the window can mean entries liquidate at a higher rate by default.
• Monitor liquidation notices in ACE and act on bills and refunds promptly. When CBP issues a bill for an underpayment, track the protest deadline carefully. When a refund is owed, confirm it is received with the correct interest amount.
