Customs Brokerage Audit: What CBP Actually Evaluates and Why Outcomes Are a Lagging Indicator

When preparing for a customs brokerage audit, brokerages often review their error rates and clean up recent entries. That may be the wrong approach, because errors that surface during an audit reflect what has already gone wrong. They don't always show what's going wrong right now. By the time inconsistent HTS codes or valuation errors appear in filing data, the process causing them may have been failing for months.

Customs brokerage audits test process discipline because CBP looks at the system behind an entry, not just the entry itself. That distinction changes how every licensed customs broker should think about audit readiness.

What CBP Evaluates During a Customs Brokerage Audit

A customs brokerage audit shows whether a brokerage has documented its processes and built consistent decision-making procedures that support accurate entries over time. CBP isn't just checking whether one entry was filed correctly. It wants to know whether the operation is set up to produce accurate entries consistently.

CBP conducts several kinds of audits that look at different parts of a company's controls. A pre-assessment survey is a questionnaire that checks internal controls before CBP decides whether a closer look is warranted. A focused assessment is more formal and may include three phases, starting with an evaluation of internal controls before moving to an entry-level review. Quick response audits focus on a specific compliance issue CBP has already identified.

These audits differ, but they often examine the systems behind the entries: internal SOPs, classification procedures, training for entry writers, and the processes used to catch errors before filing. CBP also reviews record retention. Under 19 USC 1508, brokers and importers must keep customs records for at least five years. If brokers cannot produce those records during an audit, the missing documentation may point to weak controls, even when the underlying entries are accurate.

Common Pitfalls CBP Finds During Focused Assessments

CBP audits often reveal patterns, and those patterns matter because they can point to a missing or broken process upstream of the filing.

HTS misclassification is one common problem. It becomes more concerning when the same product is classified differently across several entries over several months. That inconsistency may mean the brokerage lacks a current product database or a process to check new entries against earlier classifications. HTS classification can involve difficult judgment calls, but different codes for the same product still point to a process gap.

Valuation errors create a similar problem. They don't always stem from an incorrect transaction value on the commercial invoice. Brokerage staff may leave assists, royalties, or selling commissions out of the transaction value because there is no clear process to confirm those charges with the importer before filing.

Country-of-origin inconsistencies develop the same way. A supplier may list one country of origin on a purchase order and a different one six months later. If no one at the brokerage spots the change, the discrepancy carries into later entries. Supply chain mapping is how importers catch this before CBP does. Tariff stacking creates another source of risk. Section 301, Section 232, and IEEPA tariffs can sit on top of base HTS rates, and if the Chapter 99 sequence is wrong, the duty exposure repeats across every affected entry.

Why Compliance Testing Starts With Your Process

Compliance testing looks at the systems companies use to prepare entries. If a brokerage fixes one bad entry but leaves the process that caused it untouched, the same problem may appear again in the next audit.

Hugo Pakula, CEO of Tru Identity, described poor results as a sign of the process behind them: "The outcomes are basically a lagging indicator of your process. So if you have a great process, arguably, you will not have those bad results that CBP is looking for." (It's the same test CBP applies when it decides what makes a bad broker.)

In practice, process means documented procedures for areas like classification and valuation. A classification decision should be documented when it is made, so the brokerage doesn't have to rebuild its reasoning after receiving a CF-28. Pakula also pointed to employee training, transaction reject rates, and access to current regulations and the HTS as factors tied to responsible supervision and control.

Access to current compliance information matters too. The people making filing decisions need current regulations, the HTS, and other CBP notices at hand. Pakula offered a simple way to judge whether your records would stand up to review: "Imagine what they're going to ask you. What is the officer's face going to look like when he looks at each of the individual records and sees the work you've been doing?"

How Post-Summary Corrections and Protests Recover Overpaid Duties

Customs brokerage audits can also reveal duty overpayments, missed preferential rates, and other money to be recovered. Brokerages miss this side of an audit when they focus only on enforcement risk and don't check whether they overpaid duty on past entries.

For entries that have not yet liquidated, a post-summary correction (PSC) may let a company recover duty if it is filed within the required period. Once an entry has liquidated, a protest generally must be filed within 180 days under 19 USC 1514.

The practical point is simple: an internal review before CBP arrives does more than reduce enforcement exposure. It can also help an importer find money lost to incorrect classifications, missed free trade agreement eligibility, or valuation errors, and across hundreds or thousands of entries those amounts add up.

How Tru Identity Helps Customs Brokerages Build Audit-Ready Compliance Records

Tru Identity provides documented, versioned records that show how a brokerage made each compliance decision. A classification decision is linked to the rules in effect at the time of entry, so the supporting record already exists if CBP asks about it months later.

Tru was selected in the first round of CBP's Commercial Solutions Opening Pilot (CSOP). Pakula argues that this relationship matters because compliance is not only about getting the result right. Brokers also need to show CBP how they reached it.

"Our partnership with CBP enables you not just to get compliant, but to demonstrate your compliance to CBP," Pakula said.

The Compliance Review Funnel can reduce 10,000 product lines to about 40 that require a licensed broker's judgment. That gives the brokerage a record across the whole catalog, not only the entries that happened to get human review, and it can turn an audit from reconstructing past decisions into showing work already done.

Frequently Asked Questions

Q1. How long must customs records be retained for a CBP audit?

Customs brokers and importers must generally keep required customs records for at least five years under 19 USC 1508. These records can include entry summaries, commercial invoices, packing lists, classification records, country-of-origin documents, and correspondence with importers. Failing to produce required records during an audit can create compliance problems.

Q2. What is a focused assessment in customs compliance?

A focused assessment is a structured CBP audit that evaluates compliance risk and internal controls. It can include several stages, starting with a review of controls and procedures before moving into more detailed testing of entries.

Q3. What happens if CBP finds errors during a customs audit?

CBP may issue a CF-29, or Notice of Action, proposing changes such as rate advances, classification changes, or value adjustments. Depending on the facts, violations may also lead to penalties under 19 USC 1592. Repeated problems can draw greater enforcement attention.

Q4. Can a customs broker be held liable for entry errors?

Customs brokers have duties under 19 CFR Part 111, including supervising and controlling customs business conducted under their license. While the importer of record has its own legal responsibilities, a broker can also face consequences for failures connected with its brokerage duties.

Q5. What is the difference between a post-summary correction and a protest?

A post-summary correction is used to correct an eligible entry before liquidation, subject to CBP's filing rules and deadlines. A protest is generally filed after liquidation to challenge a CBP decision. The two procedures apply at different stages of the entry process.
