Customs Broker Books: What Importers Need to Know in 2026
As of June 11, 2026, CBP has sharpened its enforcement focus on customs broker books — the transaction records, entry files, and compliance documentation that licensed brokers are required to maintain under federal law. For U.S. importers, this is not an abstract regulatory matter: if your broker’s records are incomplete, your shipments, your duty payments, and your import privileges are at risk.
What Happened
Customs broker books — defined under 19 CFR Part 111 as all records related to import transactions handled by a licensed customs broker, including entry filings, invoices, powers of attorney, and client correspondence — have become a focal point for CBP compliance audits in 2026.
CBP has historically conducted broker compliance reviews as part of its licensing oversight process under 19 USC § 1641. In late 2025 and into 2026, the agency intensified those reviews, specifically targeting the quality and completeness of electronic records as more brokers transitioned away from paper-based filing systems following the full ACE (Automated Commercial Environment) mandate.
The core issue: many brokers digitized their workflows but did not establish clear internal systems for storing, organizing, and retrieving broker books in the format CBP expects. During audits, examiners have flagged missing power of attorney documents, incomplete entry packages, and email correspondence that cannot be produced on demand.
According to 19 CFR § 111.23, licensed customs brokers must retain records for five years from the date of entry. Failure to produce records during a compliance review can result in suspension or revocation of a broker’s license. CBP processed approximately 36 million formal and informal entries in fiscal year 2024, and each one carries a recordkeeping obligation.
The National Customs Brokers & Forwarders Association of America (NCBFAA) has issued updated best-practice guidance for member brokers, recommending standardized electronic document management systems and annual internal audits.
Why It Matters to Importers
Most importers assume recordkeeping is the broker’s problem. It is not — not entirely.
Under 19 CFR Part 163, importers of record carry independent recordkeeping obligations. If CBP audits your entries and your broker cannot produce the supporting documentation, the importer of record can face:
- Penalties under 19 USC § 1592 for entry inaccuracies, even if the error originated with the broker
- Delays on future entries while CBP investigates record gaps
- Loss of broker relationship if the broker’s license is suspended pending a compliance review
Beyond penalties, there is a practical risk: if your broker cannot show clean books, you do not have a reliable compliance partner. Importers who discovered record gaps in 2025 often could not reconstruct duty payment histories or ISF filing timestamps — documentation that matters in protest proceedings and classification disputes.
Impact by Stakeholder
| Affected Party | What Changes | Severity |
|---|---|---|
| Licensed customs brokers | Must produce complete digital or paper records on CBP demand within 30 days | High |
| Importers of record | Risk penalty exposure if broker records supporting their entries are missing | High |
| Freight forwarders acting as brokers | Subject to same 19 CFR Part 111 recordkeeping rules as standalone brokers | High |
| New or small broker offices | Higher audit risk if internal document systems are informal or inconsistent | Medium |
| Importers using multiple brokers | Fragmented records across providers increase audit complexity | Medium |
Affected Goods, Industries, and Trade Lanes
Recordkeeping requirements apply to every formal entry filed with CBP, regardless of commodity. However, the enforcement focus in 2026 has been most acute in:
- High-duty goods subject to Section 301 tariffs (electronics, machinery, apparel from China) — these entries carry additional documentation requirements for tariff exclusions and HTS classification, per hts.usitc.gov
- Antidumping and countervailing duty (AD/CVD) entries — AD/CVD orders require broker books to include scope rulings and certification records; the enforcement database at enforcement.trade.gov/adcvd tracks active orders across hundreds of product categories
- FDA-regulated goods (food, pharmaceuticals, medical devices) — these require entry packages to include additional agency release documentation that must be retained alongside CBP records
- Entries at high-volume ports — Los Angeles/Long Beach, New York/Newark, and Chicago O’Hare have seen the most compliance review activity; browse brokers by U.S. port of entry to find specialists at your gateway
Importers bringing in goods from China, Mexico, and Canada via land border ports should also note that electronic records for Section 321 de minimis entries are now subject to the same five-year retention rule following CBP guidance updates in late 2025.
What Importers Should Do Now
-
Request a records audit from your current broker. Ask them to confirm they have complete entry packages — including commercial invoices, packing lists, CBP Form 7501, and power of attorney — for every formal entry filed on your behalf in the past five years. A reputable broker will produce these without hesitation.
-
Verify your power of attorney is current and on file. POA documents expire or get lost in broker transitions. Confirm your broker holds a valid, signed POA that covers the scope of transactions they file for you. Missing POAs are one of the most common findings in CBP compliance reviews.
-
Confirm your own recordkeeping obligations under 19 CFR Part 163. Your broker’s records and your records as importer of record are separate obligations. Review your internal files — purchase orders, import invoices, classification worksheets — against the five-year retention rule.
-
Check your broker’s license status directly on CBP.gov. Active license status is public information. Search the CBP broker license lookup at CBP.gov to confirm your broker’s license is current and has no pending disciplinary actions.
-
If your broker cannot produce records on request, find a new broker. Use CustomsBrokerIndex.com’s search tool to find CBP-licensed brokers verified against official CBP records. You can filter by port, state, and specialty — including brokers who specialize in pharmaceutical, food, electronics, and other regulated categories.
-
Document your own compliance steps. Keep a written record of when you requested a records review, what your broker provided, and any gaps identified. If CBP later audits your entries, showing that you conducted proactive due diligence is a meaningful mitigating factor in penalty proceedings.
Background Context
19 CFR Part 111 is the federal regulation governing customs broker conduct, including licensing, duties to clients, and recordkeeping. It is administered by CBP’s Office of Trade and enforced through broker compliance reviews — audits that examine whether a broker’s practices, records, and client relationships meet federal standards.
CBP began requiring all formal entry filings to be submitted through the ACE (Automated Commercial Environment) portal beginning in 2016, phasing out the legacy ACS system. While ACE created a digital filing record within CBP’s system, it did not create a broker’s internal recordkeeping system. Brokers are responsible for maintaining their own files — not just what CBP holds in ACE — including all pre-filing correspondence, client documents, and supporting records.
The five-year retention requirement mirrors the statute of limitations period under 19 USC § 1592 for penalty actions based on entry errors. In practice, CBP can request records at any point during those five years, and brokers must respond within 30 days of a formal records demand.
Brokers who fail compliance reviews can face a range of sanctions: a letter of caution, formal censure, suspension, or license revocation. When a broker’s license is suspended, every importer using that broker must immediately arrange for a replacement to clear pending shipments — a painful operational disruption that proper recordkeeping could have prevented.
For importers looking to evaluate broker practices before a crisis occurs, resources like 3PL With Customs Clearance and Warehousing Explained and broker profiles such as Davidson and Sons Customs Broker and Interglobo Customs Broker Inc offer useful benchmarks for what a professionally managed broker operation looks like. You can also browse brokers by state to find licensed, verified options near your operations.
