9.3 Broker Duties, Diligence, Funds Handling, and Prohibited Relations

Key Takeaways

  • Under 19 CFR 111.29, brokers must exercise due diligence in preparing customs documents, answering correspondence, and promptly paying client funds received for duties and taxes to CBP.
  • Client funds received for duties are held in a strict fiduciary capacity; commingling with operating accounts or diverting duty funds to offset unpaid service fees violates federal regulations.
  • 19 CFR 111.36 strictly prohibits sharing brokerage fees, paying rebates, or dividing customs commissions with unlicensed persons, including freight forwarders.
  • Brokers may compensate forwarders solely for bona fide non-customs clerical services under a written contract, and must provide an itemized billing disclosing actual CBP charges directly to the importer.
  • Under 19 CFR 111.39, a broker who discovers client error or noncompliance must advise the client promptly in writing, but is not required to disclose the noncompliance to CBP.

9.3 Broker Duties, Diligence, Funds Handling, and Prohibited Relations

Ethical & Fiduciary Framework: Due Diligence Mandate (19 CFR 111.29) | Strict Prohibition against Fee-Splitting with Unlicensed Persons (19 CFR 111.36) | Itemized Direct Billing Transparency | False Statements Prohibition (19 CFR 111.32) | Client Noncompliance Disclosure Rules (19 CFR 111.39) | Check Negotiation Restrictions (19 CFR 111.37).

Diligence in Correspondence, Document Filing, and Funds Handling (19 CFR 111.29)

Customs brokers operate under stringent fiduciary and ethical obligations codified in 19 CFR Part 111, Subpart C. Chief among these is the affirmative duty of due diligence established in 19 CFR 111.29(a). Under this provision, a licensed broker must exercise due diligence in:

  1. Preparing or assisting in the preparation and filing of customs declarations, entries, entry summaries, protests, and drawback claims.
  2. Inquiring into the correctness of facts, classifications, and valuations declared to CBP.
  3. Answering correspondence and inquiries received from CBP officials in a timely and accurate manner.
  4. Paying over to the Government, or to a client, all funds received on behalf of the Government or client.

Fiduciary Duty Regarding Government and Client Funds

The handling of client duty funds represents one of the most heavily scrutinized areas of customs broker regulation. Commercial importers frequently transmit large sums of money—often hundreds of thousands of dollars—to customs brokers to satisfy estimated customs duties, excise taxes, Antidumping/Countervailing Duties (AD/CVD), and Merchandise Processing Fees (MPF). Under 19 CFR 111.29(a):

  • Fiduciary Custody: These funds do not become the property of the customs broker. The broker holds them strictly as a fiduciary trustee for the explicit purpose of paying the United States Government.
  • Prompt Payment Mandate: The broker must promptly disburse client duty funds to CBP within the statutory payment deadlines (e.g., within 10 working days of entry summary filing or within the statement processing deadline under 19 CFR 24.25).
  • Immediate Accounting and Refund: If the broker receives funds from a client that exceed the actual duties and fees owed, or if CBP issues a duty refund or drawback payment to the broker on behalf of a client, the broker must immediately account for those funds and transmit the balance directly to the client under 19 CFR 111.29(b).
  • Prohibition Against Commingling and Offsets: A broker cannot commingle client duty funds with general corporate operational bank accounts, use client duty money to finance operational payroll, or utilize duty payments received from Importer A to satisfy duties owed by Importer B. Most critically, a broker is strictly prohibited from withholding or diverting client duty funds to satisfy outstanding, disputed commercial receivables or unpaid brokerage fees owed by the client to the broker.

Relations with Unlicensed Persons and Fee Splitting Prohibitions (19 CFR 111.36)

To preserve the professional integrity of customs brokerage and prevent unlicensed commercial entities from controlling customs declarations, 19 CFR 111.36 establishes an absolute prohibition against fee-splitting and unauthorized commercial relationships.

The Absolute Prohibition on Fee-Splitting (19 CFR 111.36(a))

Under 19 CFR 111.36(a), no customs broker may enter into any agreement with an unlicensed person, corporation, or freight forwarder to:

  • Share fees, profits, or commissions derived directly or indirectly from customs business.
  • Pay rebates, kickbacks, or referral fees carved out of brokerage charges.
  • Allow an unlicensed person to dictate, control, or solicit customs business on behalf of the broker.

Legitimate Freight Forwarder Compensation vs. Prohibited Rebates (19 CFR 111.36(c))

In commercial international trade, ocean and air freight forwarders frequently coordinate cargo movements and introduce import clients to licensed customs brokers. The regulatory line between legitimate freight forwarding compensation and illegal fee-splitting is rigid:

  • Permissible Non-Customs Clerical Services: A customs broker may compensate an unlicensed freight forwarder or logistics company solely for bona fide, non-customs clerical services (such as tracking arrival notices, assembling ocean bills of lading, coordinating terminal cargo delivery, or sorting commercial documents) pursuant to a written agreement detailing the specific services rendered and establishing reasonable, non-customs-based compensation.
  • Strictly Prohibited Fee Sharing: A broker cannot pay a forwarder a percentage of the brokerage fee, pay a flat "kickback" per entry summary filed, or rebate customs fees back to the forwarder.
  • Mandatory Direct Billing Transparency: Under 19 CFR 111.36(c)(2), the broker must transmit an itemized billing directly to the importer of record, or ensure that the importer receives a true copy of the broker's bill that explicitly discloses actual CBP duties, taxes, and fees separately from the broker's professional service fees. This prevents freight forwarders from "padding" customs duties or concealing unlawful fee-splitting markups.

False, Deceptive, or Misleading Information (19 CFR 111.32)

Under 19 CFR 111.32, a broker must not withhold information from CBP or knowingly impart false, deceptive, or misleading information to CBP or to a client. This prohibition applies to any statement, declaration, document, certificate of origin, or electronic transmission.

If an importer requests a broker to classify goods under a tariff heading that the broker knows is legally incorrect (e.g., classifying a finished garment under an unfinished fabric heading to lower duty rates), or asks the broker to declare an artificially deflated commercial value on CBP Form 7501, the broker must refuse. Knowingly participating in false statements constitutes grounds for civil monetary penalties under 19 CFR 111.91, immediate license revocation proceedings under 19 CFR 111.53, and potential criminal prosecution under 18 U.S.C. § 1001 for making false statements to a federal agency.


Client Noncompliance, Errors, and Fraud (19 CFR 111.39)

A frequent scenario on the Customs Broker License Exam involves the broker discovering an error or omission committed by an importer client. The governing rule is codified in 19 CFR 111.39:

+-------------------------------------------------------------------------+
|                   19 CFR 111.39 REGULATORY DIRECTIVE                    |
|  "If a broker knows that a client has not complied with the law, or     |
|   has made an error in, or omission from, any document, affidavit,      |
|   or other paper which the law requires the client to execute, the       |
|   broker MUST advise the client promptly of the fact of such             |
|   noncompliance, error, or omission."                                    |
+-------------------------------------------------------------------------+

The Broker's Dual Regulatory Posture

  1. Affirmative Duty to the Client: The broker must notify the client promptly upon discovering the noncompliance, error, or omission. Professional best practice dictates delivering this notice in writing, documenting the exact nature of the error (such as an undeclared assist or incorrect valuation formula) and recommending the lawful corrective remedy — a Post Summary Correction transmitted in ACE under the ACE Entry Summary Business Rules and Process Document if the entry is still unliquidated, an administrative protest under 19 U.S.C. § 1514 if it has liquidated, or a prior disclosure under 19 U.S.C. § 1592(c)(4) and 19 CFR 162.74.
  2. Confidentiality Regarding Past Errors (No Duty to Report to CBP): Critically, 19 CFR 111.39 does NOT require the broker to disclose the error to CBP. Customs regulations deliberately preserve confidentiality between the broker and client regarding past noncompliance. This encourages commercial importers to consult compliance professionals without fear that their broker will serve as an automatic government informant. The statutory decision to disclose past violations under 19 U.S.C. § 1592 belongs exclusively to the importer of record.
  3. The Line of Non-Participation in Continuing Fraud: While the broker is not required to report past noncompliance to CBP, the broker cannot participate in continuing or ongoing illegal acts. If the client refuses to correct the error and demands that the broker file future entry summaries incorporating the fraudulent data, the broker must refuse the transaction and terminate representation regarding those entries pursuant to 19 CFR 111.32. Assisting a client in perpetuating an active fraud forfeits all regulatory protection.

Negotiation of Client Checks and Financial Restrictions (19 CFR 111.37)

Under 19 CFR 111.37, a broker is strictly prohibited from endorsing or negotiating any draft, check, or commercial paper drawn payable to the order of a client, or issuing an endorsement upon any government refund check made payable to the importer, without a specific, express written legal power of attorney explicitly authorizing the broker to endorse and negotiate client commercial paper. A standard customs power of attorney authorizing entry filing does not convey check negotiation authority.

Vanguard Logistics, an unlicensed international ocean freight forwarder, proposes an agreement with Pioneer Customs Brokers: Vanguard will route all of its import customers exclusively to Pioneer, and in return, Pioneer must remit a 20% "referral commission" carved out of Pioneer's customs brokerage fee for every entry summary filed. Vanguard also insists that Pioneer issue a single, unitemized lump-sum invoice to Vanguard that merges brokerage fees and CBP duties. How do CBP regulations treat this proposed arrangement?

An importer client wires $50,000 to its licensed customs broker specifically earmarked to satisfy estimated customs duties and merchandise processing fees on an incoming ocean container shipment. The broker notices that the client owes $12,000 in past-due, disputed brokerage and warehousing invoices that have been outstanding for 90 days. The broker applies $12,000 of the client's wire transfer to satisfy the overdue service invoice and remits only $38,000 to CBP, resulting in an entry rejection and penalty notice.
