How to Handle a CBP Customs Audit
A CBP customs audit is a formal review of your import records to confirm you paid the right duties and followed customs law — and the one most importers encounter is the Focused Assessment, conducted by CBP’s Regulatory Audit and Agency Advisory Services (RAAAS). An audit is not an accusation; it is a risk-based check of your internal controls. But how you prepare, and whether your five years of records hold up, determines whether it ends quietly or with a penalty. This guide explains the audit types, what triggers them, and how to come through one clean.
The Main Audit Types
CBP runs audits at two scales, and knowing which one you face shapes your response.
| Audit type | Scope | What CBP is doing |
|---|---|---|
| Focused Assessment (FA) | Comprehensive | Evaluating your overall import internal controls for acceptable risk |
| Quick Response Audit (QRA) | Narrow, single-issue | Testing one specific concern — a product, a valuation issue, a program claim |
A Focused Assessment begins with a Pre-Assessment Survey (PAS), in which auditors map your internal-control environment, identify high-risk transaction types, and produce a written risk ranking. If the PAS shows weak controls, CBP proceeds to compliance testing of actual entries; if your controls are strong, the audit can close without transaction-level testing. The PAS is therefore the phase where good documentation pays off most.
What Triggers an Audit
CBP selects audit targets by risk, not at random. Common triggers include a high volume of duties paid, prior entry errors or penalty history, importing goods subject to antidumping or countervailing duties, claims under trade-preference programs, and industry-wide enforcement initiatives. Importers who have never built a compliance program are statistically more likely to surface as a risk — which is the argument for managing import risk before CBP comes calling.
Records Are the Whole Game
An audit lives or dies on your records. Under 19 U.S.C. § 1508, importers must keep entry records for five years from the date of entry, and an audit is exactly when CBP asks to see them. Be ready to produce, for any entry:
- Commercial invoices, packing lists, and the entry summary (CBP Form 7501).
- Classification support — how each HTS code was chosen.
- Valuation support — proof of the price paid and treatment of assists, commissions, and royalties.
- Proof of any preference or special-program claim.
An importer who cannot produce records faces penalties under the recordkeeping statute on top of any duty loss — independent of whether the underlying entries were correct. Organize records by entry number so any one can be reconstructed on demand.
Found a Problem First? File a Prior Disclosure
If an internal review turns up errors before CBP does, you have a powerful tool: a prior disclosure under 19 U.S.C. § 1592(c)(4). Disclosing the violation to CBP before the agency learns of it — and tendering the unpaid duties — sharply limits the penalty exposure. A prior disclosure made before an audit begins is far cheaper than the penalty CBP would otherwise assess. This is why a self-audit ahead of any CBP contact is worth the effort.
During the Audit
When the audit is underway, a few practices keep it on track: designate a single point of contact, answer exactly what is asked without volunteering unverified information, keep your own copy of everything provided, and bring in customs counsel early if valuation, classification, or penalty exposure is in play. If you disagree with the result, you retain the right to protest CBP’s decisions within 180 days of liquidation under 19 U.S.C. § 1514.
Frequently Asked Questions
What is a CBP Focused Assessment?
It is CBP’s comprehensive audit of an importer’s internal controls over import activity, run by the Regulatory Audit and Agency Advisory Services division. It starts with a Pre-Assessment Survey that ranks your compliance risk and may proceed to testing actual entries if controls are weak.
What triggers a customs audit?
Risk factors such as high duty volume, prior errors or penalties, importing AD/CVD or preference-program goods, and industry enforcement initiatives. CBP selects targets by risk rather than at random.
How far back can a customs audit reach?
Importers must keep entry records for five years from the date of entry under 19 U.S.C. § 1508, and CBP can recover underpaid duties over that same five-year period, so an audit can reach back five years.
Can I reduce penalties if I find an error before CBP does?
Yes. Filing a prior disclosure under 19 U.S.C. § 1592(c)(4) before CBP discovers the violation, and paying the duties owed, substantially limits the penalty. A self-audit that catches errors early is the key to using this tool.
