CBP prior disclosure: correcting US import errors before an investigation
If a US importer finds that past entries understated value, used the wrong classification or claimed a preference wrongly, it can make a prior disclosure to CBP under 19 CFR 162.74 before, or without knowledge of, a formal investigation. If it also pays the lost duties, the penalty under 19 U.S.C. 1592 is limited to interest for negligence or gross negligence, instead of up to two or four times the lost duties.

What a prior disclosure is
A prior disclosure is made when a person tells a CBP officer, orally or in writing, about the circumstances of a violation of 19 U.S.C. 1592 or 1593a before, or without knowledge of, a formal investigation of that violation, and tenders the actual loss of duties, taxes and fees. An oral disclosure must be confirmed in writing to the Fines, Penalties and Forfeitures Officer within 10 days.
A formal investigation starts on the date CBP records in writing that it had information suggesting a possible violation. Knowledge of an investigation is presumed if, before the disclosure, CBP told the person about the violation, a Special Agent asked about it or requested records, a prepenalty or penalty notice was issued or the goods were seized; the person can try to rebut this.
What the disclosure must contain (162.74(b))
- The class or kind of merchandise involved
- Each entry or drawback claim by number, or by port and approximate dates
- The material false statements, omissions or acts, and how and when they occurred
- The true and accurate information, with a commitment to provide unknown information within 30 days
- A written disclosure is addressed to the Commissioner of CBP, marked "prior disclosure" on the envelope and presented at the port of entry; for several ports, identify all ports concerned
Paying the loss and the effect on penalties
The importer tenders the actual loss of duties, taxes and fees at the time of disclosure or within 30 days after CBP gives its calculation in writing; failing to pay the final amount means the prior disclosure is denied. Where CBP's calculation exceeds $100,000, the party may ask for Headquarters review under conditions set in the rule. Statistical sampling can be used with CBP's approval.
With a valid prior disclosure, the penalty for negligence or gross negligence is limited to interest on the unpaid duties, and for fraud to 100% of the unpaid duties or 10% of the dutiable value if duties were not affected. Without it, penalties can reach two times the lost duties for negligence, four times for gross negligence, and up to the domestic value of the goods for fraud. Violations outside the scope of the disclosure do not get prior disclosure treatment.
Step by step
- When you find an error in past entries, check whether CBP has already contacted you about it.
- Identify the merchandise, entries, ports and dates affected, and what was wrong.
- Prepare the written disclosure with the 162.74(b) contents, marked "prior disclosure", and present it to CBP at the port of entry.
- Pay the actual loss of duties, taxes and fees at disclosure or within 30 days after CBP's calculation.
- Provide any missing information within 30 days and fix the process that caused the error.
Documents you usually need
- Written prior disclosure marked "prior disclosure"
- List of affected entries or drawback claims
- Corrected values, classifications or other data
- Calculation and payment of the loss of duties
- Sampling plan approved by CBP, if sampling is used
Common problems and how to avoid them
What to do: Knowledge of an investigation is then presumed; disclose as soon as an error is found, before CBP contacts you.
What to do: Confirm an oral disclosure in writing to the Fines, Penalties and Forfeitures Officer within 10 days.
What to do: Pay within 30 days of CBP's written calculation, or the prior disclosure is denied.
What to do: Violations outside the scope of the disclosure do not get prior disclosure treatment; review all affected entries before disclosing.
