Who is responsible for tariff classification? What importers need to know about customs powers of attorney.

When an importer retains a licensed customs broker, there is often an implicit assumption that the broker will “handle everything” — including determining the correct Harmonized Tariff Schedule (HTS) classification for imported merchandise. That assumption is legally incorrect, and it is one that CBP will not share.

The reality is that under both federal law and the standard terms governing most broker-client relationships, tariff classification is the importer’s responsibility. The customs power of attorney transfers the authority to act on your behalf; it does not transfer the obligation to get it right.

The Legal Foundation: The Importer of Record’s Duty of Reasonable Care

The Customs Modernization Act of 1993 (the “Mod Act”), codified at 19 U.S.C. § 1484(a), establishes that the importer of record bears personal responsibility for using “reasonable care” to enter, classify, and value imported merchandise accurately and to provide any other information necessary for CBP to properly assess duties and determine admissibility.

This reasonable care standard is non-delegable in any meaningful sense. An importer cannot transfer its legal exposure to a broker simply by signing a power of attorney. CBP’s guidance on reasonable care makes clear that importers are expected to understand their products, consult qualified advisors, and take affirmative steps to ensure classification accuracy — not merely rely on whoever happens to be filing the entry.

If CBP issues a penalty for misclassification under 19 U.S.C. § 1592, that penalty runs against the importer of record, not the broker — unless the broker independently committed a culpable act. A claim that “my broker classified it” is not a defense; it is, at best, a mitigating factor relevant to the level of culpability (negligence, gross negligence, or fraud) and the associated penalty calculation.

What the Power of Attorney Actually Does

A customs power of attorney, executed under 19 C.F.R. § 141.32, authorizes the broker to transact customs business on the importer’s behalf. It grants the broker the legal capacity to sign entry documents, make representations to CBP, and otherwise act as the importer’s agent for customs purposes.

What the power of attorney does not do is assign professional responsibility for classification determinations to the broker. The broker acts on the information and instructions the importer provides. When the importer furnishes an HTS number, a product description, or a country of origin, the broker — absent a separate arrangement — is generally entitled to rely on that information in preparing the entry.

This is not a loophole. It reflects the fundamental nature of the agency relationship: the principal (the importer) directs the agent (the broker), and the agent acts within the scope of those directions.

What the NCBFAA Standard Terms and Conditions Say

Most licensed customs brokers in the United States operate under terms and conditions either modeled on or directly incorporating the National Customs Brokers & Forwarders Association of America (NCBFAA) Standard Terms and Conditions. These terms are frequently incorporated by reference into broker-client agreements and power of attorney forms, sometimes on the reverse side of a document the importer signs without reading carefully.

The NCBFAA Standard Terms and Conditions are explicit on the question of classification responsibility. The customer — the importer — warrants the accuracy and completeness of all information it provides to the broker, including commodity descriptions and classification numbers. The broker is authorized to rely on that information in preparing and filing entry documents. Unless the broker has separately agreed — in writing — to provide classification services, the broker’s role is to transmit and file, not to independently determine the correct HTS number.

The NCBFAA terms also include a provision under which the customer agrees to indemnify and hold the broker harmless from losses, costs, or penalties arising from the customer’s failure to provide accurate information or instructions. Read together, the standard terms create a clear allocation of risk: the importer provides the classification; the broker files it; and if the classification is wrong because the importer got it wrong, the importer bears that exposure.

The Practical Gap: When No One Classifies Formally

The problem in practice is that many importer-broker relationships operate in an informal gray zone. The importer may never provide an HTS number explicitly; the broker simply “fills it in” based on the product description or past practice. Neither party has a written classification agreement. Neither party has confirmed in writing who bears responsibility.

In that scenario, if CBP later challenges the classification — through a CF-28 Request for Information, a CF-29 Notice of Action, or a formal penalty proceeding — the question of who is responsible becomes a point of real contention. The importer believes the broker classified the goods. The broker believes it was relying on the importer’s implied representation of what the goods were. The entry is wrong, and someone owes duties, interest, and potentially penalties.

This ambiguity is resolved, in most standard agreements, in the broker’s favor — because the NCBFAA terms and similar provisions place the classification obligation on the importer. But “resolved in the broker’s favor” is cold comfort to an importer facing a significant CBP action.

What a Separate Classification Agreement Changes

A broker can, and often does, agree to provide classification services as a distinct professional undertaking. In that case, the broker accepts the professional responsibility that comes with that role. The importer is entitled to rely on the broker’s classification determination, and if that determination is wrong, the broker may bear a share of the resulting liability — subject to whatever limitations of liability appear in the agreement.

This kind of engagement should be documented clearly. It should:

• Identify the specific products to be classified;
• State the standard of care the broker is undertaking (reasonable care; best professional judgment; etc.);
• Address what information the broker requires from the importer to perform the classification;
• Specify the broker’s liability exposure and any cap on damages; and
• State whether the broker’s classification determination is binding on the importer or advisory in nature.

Without these elements, even a broker who routinely classifies goods for a client may not have entered into a legally enforceable classification services agreement that shifts liability in any meaningful way.

Why Classification Advice From a Customs Attorney Is Different

Even a well-drafted classification agreement with a broker does not provide importers with everything a customs attorney can. The distinction between broker services and legal advice is not merely formal — it has concrete, practical consequences that affect an importer’s exposure in CBP proceedings and litigation.

Customs Brokers Cannot Practice Law

Licensed customs brokers are authorized under 19 U.S.C. § 1641 to conduct “customs business” on behalf of their clients. That authority does not include the practice of law. A broker who renders legal opinions on classification — as distinct from operational classification determinations — may be engaging in unauthorized practice of law. More importantly for the importer, a broker’s classification analysis does not carry the legal protections that attach to advice from counsel.

Attorney-Client Privilege Protects Classification Communications

When an importer asks a licensed customs attorney for advice on how to classify a product, that communication is protected by attorney-client privilege. It cannot be compelled in discovery, demanded by CBP in a focused assessment, or used against the importer in a penalty proceeding — unless the importer voluntarily waives the privilege.

No such protection exists for communications with a customs broker. If CBP or a court issues a subpoena or summons to your broker, your broker can be required to disclose what you told them about your merchandise, what analysis they performed, what alternative classifications they considered, and why they arrived at a particular HTS number. That information can then be used by CBP to establish the duty owed, the period over which a misclassification persisted, and whether the importer acted with negligence, gross negligence, or fraud.

The Work Product Doctrine Extends Protection to Legal Analysis

The work product doctrine provides a further layer of protection when classification advice is sought from counsel in connection with anticipated or ongoing legal proceedings — including CBP penalty proceedings, protests, and actions before the Court of International Trade (CIT). Legal analysis prepared by or at the direction of customs counsel in anticipation of litigation is generally shielded from disclosure to adverse parties.

If your broker prepares a classification memorandum, an HTS analysis, or an internal review of historic entries, none of that is protected as attorney work product. It is a business record that can be subpoenaed, reviewed by CBP during a focused assessment, and introduced as evidence of what the importer knew and when. The same analysis, prepared by or under the supervision of customs counsel in connection with a live or anticipated dispute, can be withheld.

Privileged Prior Disclosure Analysis

One of the most consequential applications of this principle arises in the context of prior disclosures under 19 U.S.C. § 1592(c)(4). When an importer discovers a pattern of misclassification and wants to assess whether to file a prior disclosure with CBP — a step that can dramatically reduce penalty exposure — the analysis of which entries are affected, what duties are owed, and how to frame the disclosure is precisely the kind of work that should be performed by or under the supervision of customs counsel.

A prior disclosure analysis conducted by a broker is a business document. The same analysis conducted under the supervision of a customs attorney is protected legal work product — and the importer retains control over whether and how to disclose it to CBP.

Counsel Can Represent the Importer; a Broker Cannot

If a classification dispute escalates — from a CF-29 Notice of Action to a formal protest denial, from a Section 1592 penalty case to litigation before the CIT — only a licensed attorney can represent the importer in a legal proceeding. A customs broker can assist with the administrative stages of the process, but cannot appear in federal court, draft legal briefs, or conduct formal legal advocacy on the importer’s behalf.

Retaining customs counsel early, when a classification question first arises, creates a continuous privileged record from day one and positions the importer for effective advocacy if the dispute is not resolved at the administrative level.

Binding Rulings: The Cleanest Path to Classification Certainty

For importers who regularly bring in products where classification is uncertain or contested, the most reliable protection is a binding ruling from CBP under 19 C.F.R. Part 177. A binding ruling issued in an importer’s name requires CBP to apply that classification to the subject merchandise — provided the goods and facts match the ruling request.

Pursuing a binding ruling is itself a demonstration of reasonable care. It also provides protection in penalty proceedings: an importer who relied on a properly obtained and applicable binding ruling will have a compelling argument that it acted in good faith.

Customs counsel can prepare a binding ruling request that accurately frames the merchandise, anticipates the relevant classification arguments, and increases the probability of a favorable determination.

Key Takeaways for Importers

• The power of attorney authorizes your broker to act; it does not make your broker responsible for classification.
• The NCBFAA Standard Terms and Conditions, incorporated into most broker agreements, place classification responsibility squarely on the importer.
• “My broker classified it” is not a legal defense to a CBP penalty — it may reduce culpability, but it does not eliminate it.
• If you want your broker to bear professional responsibility for classification, that arrangement must be documented in a separate written agreement.
• For high-value or high-volume imports, a binding ruling from CBP is the most reliable way to lock in a classification and protect against penalty exposure.
• Classification advice from a customs attorney is protected by attorney-client privilege and, where litigation is anticipated, by the work product doctrine — broker communications are not, and can be compelled by CBP or in court.
• If you discover a potential misclassification, retain customs counsel before conducting any internal review — the privilege you establish at that moment may be your most valuable asset in the proceeding that follows.

Classification disputes with CBP can result in duty assessments, interest, and penalties that reach multiples of the unpaid duties. They can also trigger audits and focused assessments that extend across years of import history. The place to address classification responsibility is before the entry is filed — not after CBP sends a notice of action.
