A customs broker’s responsibilities cover the full legal and logistical work of moving imported goods into the United States for a client: classifying merchandise under the tariff schedule, determining its customs value, filing entry documents with U.S. Customs and Border Protection (CBP), calculating and paying duties and fees, arranging the required bond, verifying the importer’s identity, keeping records for years afterward, and doing all of it under a federal “reasonable care” standard that carries real penalties when it isn’t met.
What a Customs Broker Does for an Importer
Brokers are federally licensed by CBP and act on the importer’s behalf under a written power of attorney. The importer of record remains legally responsible for the accuracy of every entry, but the broker prepares the paperwork, transmits it to the government, calculates what’s owed, and serves as the day-to-day point of contact with CBP and other agencies whose approval an import may need.
The work breaks into a handful of connected duties. Each one has its own deadlines, standards, and consequences for getting it wrong.
Classifying and Valuing the Goods
Every import needs a Harmonized Tariff Schedule (HTS) code. That code sets the duty rate, so an error in either direction creates problems: the importer either overpays or underpays, and underpayment can trigger penalties and audits. Assigning the right code means analyzing a product’s physical properties, materials, and intended use, then matching those characteristics to the tariff schedule’s legal descriptions. A broker who keeps using the same code year after year without checking for reclassifications isn’t doing the job.
Alongside classification, the broker determines the customs value of the goods, which is the tax base for the duty calculation. Federal law sets a mandatory hierarchy of valuation methods.1Office of the Law Revision Counsel. 19 USC 1401a – Value The first method is transaction value, essentially the price the buyer actually paid, plus certain additions like packing costs, royalties, or assists (materials the buyer supplied to the foreign manufacturer for free). When transaction value can’t be used, because the buyer and seller are related or because no sale occurred, the statute requires stepping through the alternatives in order: the transaction value of identical merchandise, then similar merchandise, then deductive value (working backward from the U.S. selling price), then computed value (built up from production costs). A catch-all method applies only when every other approach fails. Importers can ask to skip deductive value and go straight to computed value, but that’s the only real choice; otherwise the hierarchy is not a menu.
Filing the Entry with CBP
Once goods arrive at a U.S. port, the clock starts. Entry must be made within 15 calendar days of landing. Miss that window and the merchandise goes into general-order status and can be moved to a bonded warehouse at the importer’s expense, with storage fees stacking on top of the delay.2eCFR. 19 CFR Part 141 – Entry of Merchandise
Filings go through the Automated Commercial Environment (ACE), CBP’s central trade processing system. The entry summary, historically CBP Form 7501, tells the government what the goods are, where they came from, who’s importing them, and what duties are owed.3U.S. Customs and Border Protection. ACE Entry Summary Instructions Many imports also fall under the jurisdiction of other federal agencies. Food products need FDA clearance, certain agricultural goods require USDA approval, and products containing specific chemicals may need EPA data. The broker pulls all of that into the ACE filing so nothing holds up release.
Calculating Duties, Fees, and Managing the Bond
Brokers calculate the exact duties, taxes, and fees owed on every shipment. The Merchandise Processing Fee applies to most formal entries at 0.3464% of the goods’ value, with a minimum of $33.58 and a maximum of $651.50 per entry for fiscal year 2026.4U.S. Customs and Border Protection. Customs User Fee – Merchandise Processing Fees5Federal Register. Customs User Fees To Be Adjusted for Inflation in Fiscal Year 2026 Goods arriving by sea also carry a Harbor Maintenance Fee of 0.125% of cargo value.6eCFR. 19 CFR 24.24 – Harbor Maintenance Fee
Payment usually flows through the Automated Clearing House, which gives importers additional time to move funds electronically.7U.S. Customs and Border Protection. Automated Clearinghouse (ACH) Late payments generate interest and can cost the importer its immediate release privileges, meaning future shipments get held at the port until the account is current.
None of this happens without a customs bond, which is a financial guarantee that duties and any penalties will be paid. The minimum continuous bond is $50,000, and CBP can require more based on import volume.8U.S. Customs and Border Protection. Monetary Guidelines for Setting Bond Amounts Without a valid bond, merchandise stays in government custody. Brokers procure and renew bonds for their clients; a continuous bond covers all entries during its active period rather than requiring a fresh deposit for each shipment.
Verifying the Client and Holding a Power of Attorney
A broker cannot legally represent an importer without a valid power of attorney on file. The regulations require the broker to execute that document directly with the importer of record, not through a freight forwarder or other intermediary.9eCFR. 19 CFR Part 111 – Customs Brokers For corporations, the signer must have actual authority to bind the company; partnership powers of attorney must name the general partners authorized to act.
Under rules implementing the Trade Facilitation and Trade Enforcement Act of 2015, brokers must also verify the identity of every client before transacting customs business on their behalf. When the power of attorney is obtained, the broker must collect:
- A copy of the grantor’s unexpired government-issued photo ID, plus date of birth for individuals
- The client’s IRS number or Employer Identification Number, state business registration, and any publicly available business identification number
- A recent credit report
- Physical address, phone number, email, and business website
The broker then verifies this information using methods sufficient to be “reasonably certain” of the client’s identity. CBP recommends checking government sanctions lists, reviewing articles of incorporation, and querying public databases.10Federal Register. Customs Broker Verification of an Importer’s Identity Verification records must be retained and updated annually. Skipping these steps exposes the broker to penalties up to $10,000 per client, plus possible license suspension or revocation.11Office of the Law Revision Counsel. 19 USC 1641 – Customs Brokers
The Reasonable Care Standard
Federal law requires that every entry be made “using reasonable care.”12Office of the Law Revision Counsel. 19 USC 1484 – Entry of Merchandise The importer of record bears ultimate legal responsibility for accuracy. But because the broker prepares and files the paperwork, reasonable care in practice sits heavily on the broker. That means checking that the commercial invoice matches the physical shipment, questioning inconsistencies, and flagging anything that doesn’t add up instead of filing blindly.
Where it bites hardest is classification and valuation. A broker who rubber-stamps whatever HTS code a client suggests, without independently evaluating the product, isn’t exercising reasonable care. The standard isn’t perfection; it’s the diligence a competent broker would apply under the circumstances.
Recordkeeping and Post-Entry Work
Brokers must keep all records related to an entry for at least five years from the date of entry, or five years from the date of the activity that created the record if no entry is involved.13eCFR. 19 CFR Part 163 – Recordkeeping Those files must be available for CBP inspection at any point during that period. The broker is the primary point of contact when the government has questions about historical entries or spots discrepancies in the audit trail.
Filing an entry doesn’t make the duty amount final. CBP reviews entries and eventually “liquidates” them, locking in the official duty. If CBP doesn’t act within one year of the entry date, the entry is deemed liquidated at the rate the importer originally claimed.14Office of the Law Revision Counsel. 19 USC 1504 – Limitation on Liquidation CBP can extend that window if it needs more information for classification or appraisement, but entries still unliquidated after four years are deemed liquidated by operation of law unless a court order or statute keeps them suspended.
When liquidation results in a duty increase or another unfavorable decision, the importer has 180 days from the liquidation date to file a formal protest with CBP.15Office of the Law Revision Counsel. 19 USC 1514 – Protest Against Decisions of Customs Service Miss the deadline and the decision becomes permanent. If CBP denies the protest, the next step is the U.S. Court of International Trade. Tracking liquidation bulletins and catching discrepancies quickly is squarely on the broker.
What Happens If a Broker Falls Short
CBP has broad disciplinary authority, and the consequences scale with the violation. For most infractions, CBP can impose monetary penalties up to $30,000 total per disciplinary proceeding, provided it hasn’t already opened license suspension or revocation proceedings for the same conduct.16eCFR. 19 CFR 111.91 – Grounds for Imposition of a Monetary Penalty Anyone conducting customs business without a license faces up to $10,000 per transaction.11Office of the Law Revision Counsel. 19 USC 1641 – Customs Brokers
License suspension or revocation is reserved for more serious problems, including filing applications or documents with material misrepresentations, felony or misdemeanor convictions involving imports, exports, customs business, or financial crimes like fraud or embezzlement, violating any law or regulation CBP enforces, willfully deceiving or threatening a client, terrorism-related convictions or conspiracy, and knowingly employing a convicted felon without written CBP approval.17eCFR. 19 CFR 111.53 – Grounds for Suspension or Revocation of License or Permit
A license can also be revoked automatically, without a hearing, if the broker fails to pay the annual permit fee, or if a corporate or partnership broker goes 120 consecutive days without at least one officer or partner holding an individual broker’s license. CBP gives 30 days’ written notice before an automatic revocation takes effect and publishes notice in the Federal Register.
CBP also evaluates whether a brokerage firm exercises “responsible supervision and control,” looking at staff training, the ratio of licensed brokers to total employees, transaction volume and complexity, reject rates, and how often a licensed broker audits the work of non-licensed staff.18eCFR. 19 CFR 111.28 – Responsible Supervision and Control A firm that processes thousands of entries with a single licensed broker who rarely reviews the work is going to draw scrutiny.
Typical Fees for Broker Services
Brokers generally charge a professional service fee for filing a standard formal entry, usually $100 to $200 per entry. That fee covers classification, filing, and coordination with government agencies. It does not include the duties, taxes, and government fees owed on the shipment. Complex entries with multiple tariff lines, quota merchandise, or several partner agencies involved cost more. Most brokers also charge separately for bond procurement, post-entry amendments, and protest filings. Ask for a detailed fee schedule upfront: the broker’s service fee is a small fraction of the total cost of an import transaction once duties and government fees are factored in.
