Prior Disclosure Customs 19 CFR 162.74: When Should You Self-Disclose an Error?
What changed: Clarified that the gross-negligence 40% dutiable-value ceiling applies only without revenue loss; source 19USC1592(c). Corrected before-or-without-knowledge timing, fraud and gross-negligence limits, supplementation/tender and PSC deadlines; removed unsupported schedules, interest examples and small-value route cutoff. Rechecked the statutory timing, negligence/gross-negligence interest limit,.
Consider prior disclosure when you have identified a material customs violation and can substantiate its circumstances. Eligibility requires disclosure before, or without knowledge of, commencement of a formal investigation of that violation. Do not wait for every unknown fact without assessing the regulation's initial-disclosure and supplementation rules. Valid disclosure with required tender limits civil penalties according to culpability, but does not erase the underlying duty loss. Preserve CBP communications and ask counsel to assess timing, scope and any separate enforcement exposure before selecting the route.

What does prior disclosure actually cut your penalty exposure to?
For negligence or gross negligence, a qualifying disclosure limits the civil penalty to interest on the lost duties, taxes and fees, subject to the tender requirements. Fraud has a different ceiling: the lost duties, taxes and fees, or 10% of dutiable value where duty assessment was unaffected. Without disclosure, the duty-loss ceilings are the lesser of domestic value or twice the loss for negligence and four times for gross negligence; fraud can reach domestic value.
What 19 CFR 162.74 Actually Says
Read the statute and implementing regulation together. The disclosure must identify the merchandise, transactions and material false statements, omissions or acts, and provide the correct information to the best of the disclosing party's knowledge. Unknown data must generally follow within 30 days of initial disclosure, with an extension requested where needed. Oral disclosure ordinarily requires written confirmation within 10 days. Confirm the responsible CBP office and all ports involved.
The legal test includes lack of knowledge of an investigation, rather than an absolute bar whenever CBP has already begun one. A party asserting lack of knowledge has the burden of proving it. Preserve CBP inquiries and communications and have counsel assess their scope. A CF-28 or audit contact needs a fact-specific review; do not assume it always opens or closes the disclosure route.
What Prior Disclosure Actually Saves
For a hypothetical $500,000 duty loss, without disclosure the negligence ceiling can be $1 million and gross negligence $2 million, each subject to the domestic-value cap. With a valid disclosure and required tender, negligence and gross negligence are limited to statutory interest. Fraud remains a separate analysis. These are statutory ceilings, not typical settlements or a guaranteed percentage saving.
When Prior Disclosure Is the Right Move
Assess the known violation, its affected transactions, the disclosure timing and tender requirements together. Small duty amounts do not automatically remove a material violation, and PSC or protest does not automatically give prior-disclosure protection. Record what remains unknown and obtain advice on the initial disclosure and permitted supplementation. Do not knowingly omit related facts to keep a disclosure narrow.
When Prior Disclosure Backfires
A disclosure can fail if the circumstances are incomplete, required follow-up data is not supplied, the timing test is not met or tender is late. Unknown information can be identified and supplemented under 19 CFR 162.74; a complete investigation before the initial filing is not always required. A PSC corrects eligible entry data but does not automatically provide prior-disclosure penalty protection. No unsupported $25,000 cutoff decides the route. Counsel should review related issues and the facts that establish eligibility.
The Procedural Mechanics
Build a transaction schedule and retain the entry summaries, invoices, product specifications, corrected classifications or values, and the explanation of how the error occurred. Reconcile the lost duties, taxes and fees. Tender is due at disclosure or within 30 days after CBP's written calculation, subject to an allowed extension. A promise to pay does not replace timely tender. Document corrective action and preserve what supports each conclusion.
The Reasonable Care Connection
Classification controls, periodic reviews and retained research help support reasonable care under 19 U.S.C. 1484. A prior disclosure does not by itself prove that reasonable care was exercised, and its statutory penalty limits depend on Section 1592(c)(4)'s conditions. Keep the corrective classification reasoning, entry scope and remedial actions as separate evidence.
What to Do Before Filing a Prior Disclosure
- Identify the known error, merchandise and affected transactions; list any facts still being investigated.
- Check corrected classifications, values and origins against the supporting records.
- Reconcile lost duties, taxes and fees and the required tender.
- Preserve CBP communications and have counsel assess the before-or-without-knowledge timing test.
- Track written confirmation, supplementation and tender deadlines, requesting any necessary extension.
These steps can proceed together. Do not postpone a timing assessment until every catalog record has been reviewed.
Common Prior Disclosure Scenarios
Classification error found during internal review
Record the affected entries and corrected product facts, and have counsel assess disclosure eligibility and tender. Any penalty comparison must distinguish the statutory ceiling from a negotiated outcome; a fixed interest estimate cannot be inferred from duty loss alone.
Error found after a CF-28
Preserve the inquiry and assess the violation, investigation scope and your knowledge. A CF-28 alone does not establish whether every transaction is eligible or ineligible for disclosure.
Error found during an acquisition
Review the transaction structure, the entities involved and who made or aided the original entry statements. Do not assume every historic Section 1592 liability transfers automatically to the buyer. Obtain advice on the responsible party and the disclosure position.
During a proposed acquisition, use M&A customs due diligence and successor liability to identify the target’s entry history and responsible entities before deciding the disclosure position.
Suspected error with incomplete facts
Distinguish known circumstances from facts still being investigated. Counsel can assess whether an initial disclosure with identified unknowns and timely supplementation is appropriate; do not publish a categorical rule requiring the entire investigation to finish first.
Frequently Asked Questions
What is the difference between a Post Summary Correction (PSC) and a prior disclosure?
PSC corrects eligible unliquidated entry summaries under CBP's NCAP test; it is not governed by a universal 314-day window. The ordinary deadline is 300 days from entry or 15 days before scheduled liquidation, whichever is earlier, with separate rules for qualifying extended or suspended liquidation. The July 6, 2026 notice clarifies the test. Prior disclosure addresses penalty protection for a disclosed violation and has its own timing and tender rules. One procedure does not automatically replace the other; PSC is not an IEEPA refund route.
Does prior disclosure cover origin errors and valuation errors, or only classification?
Prior disclosure covers any violation of 19 U.S.C. 1592, which includes classification, valuation, origin, and any other material false statement or omission in entry filing. The procedural mechanics are similar across error types. Valuation disclosures often involve transfer pricing issues that require additional documentation; origin disclosures often involve FTA qualification or country-of-origin marking facts.
How long does CBP take to respond to a prior disclosure?
There is no fixed completion time. The immediate deadlines are the disclosure's required follow-up information and tender, with any extension agreed by CBP. Plan from those dates, rather than an unsupported typical settlement timetable.
Can a customs broker file a prior disclosure on behalf of an importer?
A broker can prepare and submit the disclosure on the importer's behalf if authorized through a power of attorney that covers the disclosure. However, the substantive content of the disclosure is the importer's responsibility under 19 U.S.C. 1484. Most prior disclosures involving material amounts are reviewed by trade compliance counsel before submission.
What happens if CBP rejects the prior disclosure?
CBP can reject a disclosure as invalid (untimely, incomplete, inaccurate). The rejection does not eliminate the underlying 1592 exposure; it just means the disclosure does not mitigate. In some cases, CBP may reject and then proceed with the penalty case it might otherwise have pursued. This is why scoping and documentation completeness matter before submission.
Should I file prior disclosure for errors I am not sure are errors?
First distinguish a known violation from an unresolved suspicion. The regulation permits an initial disclosure that identifies missing information and timely supplementation. Counsel should assess what can be stated accurately and whether waiting could affect eligibility.
How does GingerControl support prior disclosure decisions?
GingerControl's compliance audit service, a paid service quoted for its scope, shows where your entities, brokers and records disagree and what to fix first, which helps importers see whether prior disclosure is worth raising with outside counsel before formal submission. The Classification Researcher also produces the reasoning reports that support both the corrective facts in a disclosure and the reasonable care defense that strengthens the mitigation argument.
Before You File: Get a Compliance Review
Before filing, organize the known circumstances, corrected facts and CBP correspondence and obtain advice on timing, scope and tender. An initial filing may be appropriate before every unknown fact is resolved, subject to the regulation's follow-up requirements.
Start with GingerControl's compliance audit, a paid service quoted for its scope, which shows where your entities, brokers and records disagree and what to fix first, so you can prioritize internal review before any disclosure decision.
