Prior Disclosure
/ˈpraɪər dɪˈskloʊʒər/
A prior disclosure is a voluntary self-report of a customs violation to CBP before, or without knowledge of, the commencement of a formal CBP investigation of the matter. For classification errors that resulted in duty underpayment, a valid prior disclosure sharply limits the civil penalty under 19 U.S.C. § 1592(c)(4): for negligence or gross negligence, to interest on the unpaid duties computed from the date of liquidation; for fraud, to 100% of the loss of duties (10% of dutiable value if there was no loss of duty) — provided the importer tenders the unpaid duties.

In Detail
The prior disclosure mechanism is established in 19 USC §1592(c)(4) and implemented through 19 CFR §162.74. A disclosure must be made in writing to the CBP Center director (or port director) for the port where the violation occurred and must be made before, or without knowledge of, the commencement of a formal investigation into the matter. The disclosure must identify the entries involved and describe the nature of the violation, and the importer must tender the unpaid duties, taxes, and fees either at the time of disclosure or within 30 days (or such longer period as CBP allows) after CBP notifies it of its calculation of the unpaid amount.
The penalty reduction from prior disclosure is substantial and structured. Under 19 USC §1592(c), the maximum civil penalty without a disclosure is, for negligence, the lesser of the domestic value of the merchandise or two times the loss of duties (20% of dutiable value if there was no loss of duty); for gross negligence, the lesser of the domestic value or four times the loss of duties (40% of dutiable value if no loss); and for fraud, the domestic value of the merchandise. With a valid prior disclosure — made before, or without knowledge of, the commencement of a formal investigation, and with the unpaid duties tendered — the penalty for negligence or gross negligence is limited to interest on the unpaid duties computed from the date of liquidation, and the penalty for fraud is limited to 100% of the loss of duties (10% of dutiable value if there was no loss of duty). This is a dramatic reduction, particularly for importers with large volumes of misclassified entries or significant duty underpayments.
Prior disclosure applies most commonly when an importer's internal compliance review uncovers a pattern of misclassification. When an internal audit reveals, for example, that a product has been classified under the wrong HTS code across hundreds of entries over two or three years, prior disclosure is often the strategically sound response: it limits penalty exposure materially, demonstrates good faith to CBP, and begins the process of correcting the importer's prospective classification practices. The timing requirement — disclosure must come before, or without knowledge of, the commencement of a formal investigation — incentivizes proactive internal audit programs rather than reactive compliance corrections.
Classification Significance
The availability of prior disclosure creates a strong incentive for importers to conduct periodic internal classification audits. An importer who discovers a classification error through internal review and voluntarily discloses it faces dramatically lower financial exposure than one who waits for CBP to surface the error in a Focused Assessment. The prior disclosure timeline — disclosure must come before, or without knowledge of, the commencement of a formal investigation — means that the window for penalty reduction can close as soon as CBP records that it has begun looking into the matter.
How Kanon Handles This
Kanon's version-controlled corpus and immutable classification records support internal audit programs. When corpus versions are updated and prior classifications are reviewed against current law, discrepancies can be identified systematically — providing the foundation for a prior disclosure process. The Classification Support Package documents when each classification was made and under which corpus version, supporting the timeline analysis that a prior disclosure requires.
