1. INTRODUCTION
In today’s enforcement environment, U.S. importers are under increasing scrutiny from U.S. Customs and Border Protection. One of the most critical, yet often misunderstood, documents in customs operations is the Power of Attorney.
Granting a customs broker authority to act on behalf of an importer is not a routine administrative step. It is a legally binding authorization that directly impacts compliance responsibility, entry accuracy, and liability exposure.

2. REGULATORY AND LEGAL CONTEXT
The use of a Power of Attorney in customs brokerage is governed under federal regulation, specifically:
- 19 CFR § 141.32, Power of Attorney
- 19 CFR § 111.36, Responsibility of customs brokers
- CBP Form 5291, Power of Attorney
Under these authorities, a licensed customs broker may transact customs business on behalf of an importer only when a valid Power of Attorney is in place.
CBP requires that:
- The Power of Attorney be properly executed by an authorized party
- The scope of authority be clearly defined
- The document be retained and made available upon request
- The broker exercise due diligence when accepting the Power of Attorney
Importantly, granting a Power of Attorney does not transfer compliance responsibility from the importer to the broker. The importer of record remains legally responsible under U.S. customs law.
3. WHAT CBP OR REGULATORS EXPECT
From an audit and enforcement perspective, CBP expects both importers and brokers to maintain strict control over the Power of Attorney process.
Key expectations include:
- Verification of the importer’s identity and authority to grant the Power of Attorney
- Confirmation that the signatory has legal authority within the company
- Accurate and current corporate information on file
- Defined scope of authority, including whether the broker may endorse checks or access financial data
- Ongoing monitoring of the validity of the Power of Attorney
CBP also expects brokers to apply Know Your Customer principles, including validating the legitimacy of the importer and ensuring there are no indicators of fraud or misrepresentation.
4. COMMON COMPLIANCE GAPS
Based on enforcement trends and audit findings, several recurring issues arise with Power of Attorney documentation:
- Outdated or expired Powers of Attorney still being used for active filings
- Signatures from individuals without proper corporate authority
- Failure to update corporate changes such as name, address, or ownership
- Overly broad authority granted without internal controls
- Lack of internal awareness within the importer organization regarding what was authorized
These gaps can result in rejected filings, delays in cargo release, or escalation into compliance reviews.

6. FREQUENTLY ASKED QUESTIONS
1. Does signing a Power of Attorney transfer liability to the customs broker?

2. Can a Power of Attorney be revoked?

4. Who can legally sign a Power of Attorney for a company?
An individual with legal authority within the organization, such as an officer or authorized representative.
5. Does CBP require a specific format?
CBP provides Form 5291, but alternative formats may be acceptable if they meet regulatory requirements under 19 CFR § 141.32.
6. How often should a Power of Attorney be reviewed?
Regular review is recommended, especially after corporate changes or organizational restructuring.

8. FINAL THOUGHTS
A Power of Attorney is not a procedural formality. It is a foundational compliance document that defines how customs business is conducted on behalf of an importer.
Understanding its scope, limitations, and legal implications is essential. Importers that treat the Power of Attorney process with the same rigor as entry filings and classification decisions are better positioned to avoid compliance disruptions.
Preparation, clarity, and oversight remain the key factors in managing this risk.
