Customs Power of Attorney (POA)
No customs broker or forwarder can act on your behalf without a valid power of attorney on file. It's the single document that authorizes every customs entry, ISF filing, and AES transaction — and missing it stops your shipment cold.
What Is a Customs Power of Attorney?
A legal document authorizing a customs broker or forwarder to act on behalf of an importer or exporter with CBP.
A customs power of attorney (POA) is a legal authorization that allows a licensed customs broker, freight forwarder, or agent to conduct customs business on behalf of an importer or exporter. It's required by 19 CFR §141.32 for anyone who wants a third party to file customs entries, ISF filings, or AES transactions with US Customs and Border Protection.
The POA is not a one-time per-shipment document — once executed, it remains valid until revoked by either party. It covers all customs transactions at all US ports of entry. Without a valid POA on file, your broker cannot legally clear your goods, file your ISF, or process your AES export filings.
For freight forwarders who also hold a customs broker license, the POA is the foundation document for every client relationship. It's typically one of the first documents you collect during client onboarding — before any cargo moves.
Types of Customs POA
Different authorization levels for different customs activities.
General (Unlimited) POA
Authorizes the agent to conduct ALL customs business on behalf of the principal — entries, ISF, AES, bonds, drawback claims, protests, and everything else. This is the most common type used by customs brokers and forwarders.
Limited POA
Restricts authorization to specific customs activities — for example, only customs entries, or only ISF filings. Used when the importer wants different brokers handling different functions, or wants to limit the agent's scope.
Corporate POA
Executed by a corporation, partnership, or LLC. Must be signed by an authorized officer (president, VP, treasurer, secretary) or member/manager. The signatory's title and authority must be stated on the document.
Individual POA
Executed by a sole proprietor or individual importer. Signed by the individual in their personal capacity. Simpler execution requirements than corporate POA, but the individual is personally liable.
What Does a POA Authorize?
A general customs POA covers a wide range of customs activities.
Customs Entry Filing
Filing formal and informal entries, entry summaries, and paying duties, taxes, and fees on behalf of the importer of record.
ISF Filing (10+2)
Filing the Importer Security Filing for ocean cargo. The POA serves as the written authorization required by CBP for ISF filing by a third party.
AES / EEI Filing
Filing Electronic Export Information through the Automated Export System. The POA authorizes the forwarder to act as the USPPI's authorized agent.
Customs Bond
Obtaining and managing customs bonds — both single entry and continuous — on behalf of the principal.
Protests & Post-Entry Actions
Filing protests against CBP decisions, responding to rate advances, requesting reliquidation, and other post-entry administrative actions.
Drawback Claims
Filing duty drawback claims for refund of duties paid on imported goods that are subsequently exported or destroyed.
How to Execute a Customs POA
The process is straightforward but errors can invalidate the entire document.
Use the Correct CBP Form
CBP doesn't mandate a specific form, but most brokers use either the CBP-approved template or their own version that includes all required elements. The document must clearly identify the principal, the agent, and the scope of authority.
Identify the Principal Correctly
The principal's legal name, address, and IRS EIN (or SSN for individuals) must match exactly what's on file with CBP. A mismatch between the POA name and the importer of record number will cause entry rejections.
Authorized Signatory
For corporations: must be signed by an officer authorized by the board of directors (president, VP, secretary, treasurer). For partnerships: any general partner. For sole proprietors: the individual owner. The signatory must include their title.
Witness or Notarization
CBP requires the signature to be witnessed. The witness signs the POA and provides their printed name and address. Notarization is an alternative to witnessing but is not required if a witness is present.
Broker Retains Original
The customs broker keeps the original signed POA on file. CBP can request to see it at any time. The broker must retain the POA for 5 years after the last customs transaction conducted under it.
Common POA Mistakes
These errors cause entry rejections and clearance delays.
Wrong Signatory
An unauthorized person signs the POA — e.g., an accounts payable clerk signing on behalf of a corporation without officer authority. CBP can reject all entries filed under an improperly executed POA.
Missing Witness
The witness line is left blank or the witness doesn't provide their full name and address. Without a proper witness or notarization, the POA is technically invalid.
EIN Mismatch
The EIN on the POA doesn't match the importer of record number in CBP's system. This is common when companies have multiple entities or recently changed their legal structure.
Expired or Revoked POA
Using a POA that was revoked by the principal or superseded by a new one. Brokers must maintain current POA records and check for revocation notices.
Missing Corporate Resolution
For corporations, some brokers require a corporate resolution authorizing the officer to execute the POA. While not always required by CBP, many sureties and brokers require it as best practice.
