CBP Prior Disclosure: How It Works and When to File

A CBP prior disclosure is a voluntary self-report of a customs violation that, when filed correctly and on time, dramatically limits the penalties CBP may assess under 19 U.S.C. 1592. The disclosure must reach CBP before the agency has commenced a formal investigation, and it must identify the violation, the affected entries, and tender or commit to tender any unpaid duties. Filing a valid prior disclosure converts what could be a significant monetary penalty into interest-only exposure for revenue violations involving fraud, and capped multiples for other violation classes.

Why Prior Disclosure Matters: The Penalty Stakes

19 U.S.C. 1592 creates a three-tier penalty structure based on culpability:

• Fraud: penalties up to the domestic value of the merchandise
• Gross negligence: penalties up to four times the unpaid duties, or 40% of the dutiable value if no revenue loss occurred
• Negligence: penalties up to two times the unpaid duties, or 20% of the dutiable value

These numbers can be severe. A prior disclosure under 19 U.S.C. 1592(c)(4) caps the government's remedy. For a fraud violation that involved a loss of revenue, the cap is interest on the unpaid duties, not a punitive penalty multiplier. For gross negligence and negligence violations involving a loss of revenue, penalties are limited to the interest on those duties as well. Where there is no loss of revenue, the penalty caps are reduced multiples set out in the statute. In every scenario, the reduction compared to a fully litigated enforcement action is substantial.

The Timing Requirement: "Before Commencement"

Timing is everything. A disclosure is only "prior" if CBP has not yet commenced a formal investigation of the violation you are disclosing. Under 19 CFR 162.74, CBP considers an investigation commenced when it notifies the person in writing, or when a CBP officer is designated to investigate. Practical signals that an investigation may have started include:

• Receipt of a CBP Form 28 Request for Information specifically targeting the trade practice or entries at issue
• Receipt of a CBP Form 29 Notice of Action on related entries
• A visit or inquiry from a CBP trade specialist or special agent referencing those entries
• Notice of a Focused Assessment or similar audit covering the subject matter

If any of these signals have appeared, consult qualified trade counsel immediately. The window for a valid prior disclosure may still be open, but the analysis is fact-specific and time-sensitive.

What a Valid Prior Disclosure Must Include

19 CFR 162.74 sets out the required elements. Omitting any of them risks invalidating the disclosure.

1. Identify the Violation Class

The disclosure must specify the type of violation: for example, material false statements on entry documents, material omissions, or acts that deceived CBP as to the admissibility or dutiable value of merchandise. You do not need to confess a specific culpability level, but you must describe the conduct with enough specificity that CBP can identify what went wrong and why.

2. Identify the Affected Entries

List every entry number implicated by the disclosed violation. A partial disclosure that covers only some entries is still valid for the entries listed, but CBP retains full penalty authority over any entry you omit. Conduct a thorough entry-by-entry review before filing. Courts and CBP have held that the scope of protection is limited strictly to what is disclosed.

3. Tender or Commit to Tender the Loss of Revenue

You must either pay the unpaid duties at the time of disclosure or make a written commitment to pay them within a specific timeframe. CBP's regulations set out the mechanics: if you are unable to pay in full immediately, you must state the amount owed and agree to pay it. Tendering the revenue is not optional. A disclosure that identifies the violation and entries but fails to address the duty shortfall does not perfect the statutory protection.

How to Perfect the Disclosure

A disclosure is "perfected" when it satisfies all three elements above. The process typically follows these steps:

1. Internal audit. Reconstruct every entry in the relevant time period. Calculate the duty shortfall entry by entry, including applicable tariff classifications, valuation, and any applicable special program claims.
2. Draft the disclosure letter. Address it to the port director or the Center of Excellence and Expertise with jurisdiction over the entries. Describe the violation clearly, list entry numbers, and state the calculated duty underpayment.
3. Tender payment or commit to tender. Wire or check payment is common. If you need time, the commitment must be explicit and credible.
4. File promptly. Send via certified mail or hand-deliver to preserve a clear timestamp. Keep proof of delivery.

CBP will review the disclosure and may ask follow-up questions. Cooperation and completeness at this stage preserve the protection you have already secured.

Common Mistakes That Undermine a Prior Disclosure

• Filing too late. Waiting for more information before filing can push you past the commencement threshold. When in doubt, file and supplement.
• Incomplete entry lists. Leaving out entries, even inadvertently, forfeits protection on those entries.
• Underestimating the duty shortfall. CBP will recalculate. A material understatement may affect how the agency treats the disclosure.
• Confusing a prior disclosure with a protest. A prior disclosure addresses penalty liability for past violations. A protest under 19 U.S.C. 1514 challenges CBP's liquidation of duties. They serve different purposes and have different deadlines.
• Overlooking related violations. If the root cause affected multiple HTS classifications, valuation methods, or programs, all of them should be captured in a single comprehensive disclosure rather than addressed piecemeal.

Prior Disclosure vs. Responding to a CBP Audit

An importer who receives notice of a CBP audit survey or Focused Assessment faces a different posture than one filing proactively. If the audit letter or Form 28 specifically references the entries or conduct you intend to disclose, a valid prior disclosure may no longer be available for those items. However, if your internal review uncovers additional violations not referenced in the audit notice, a prior disclosure for those separate violations may still be timely. Careful scoping of both the audit and the potential disclosure is essential.

What Importers Should Do

1. Conduct a periodic self-audit. Review recent entries for classification errors, valuation discrepancies, and program eligibility issues before CBP initiates contact. Early discovery preserves your options.
2. Act immediately on any CBP inquiry. A Form 28, a Form 29, or any written contact from CBP referencing specific entries should trigger an immediate review of whether a prior disclosure window is still open.
3. Document the full scope before filing. Run the entry list and duty calculations to completion. An incomplete disclosure creates gaps in protection and may draw additional scrutiny.
4. Engage qualified trade counsel. The prior disclosure analysis, especially identifying the commencement date and quantifying the duty shortfall, involves legal and factual judgments that can have significant financial consequences.
