Customs Power of Attorney: What Florida Importers Are Actually Signing (2026)

A customs power of attorney (POA) is the document that authorizes a licensed customs broker to file entries with CBP in your name. Without a valid POA on file, no broker can legally transact business for you. It is a short form, it is usually signed in a hurry, and it grants far broader authority than most importers realize.

What the POA actually authorizes

The standard CBP Form 5291 or its equivalent lets your broker sign and file entry documents, pay duties on your behalf, receive and respond to CBP correspondence, and generally act as your agent in customs matters. What it does not do is transfer liability. You remain the importer of record, responsible for the accuracy of every declaration filed under your name — our guide to importer of record vs. consignee explains where that line sits.

That asymmetry is the whole point to understand: the broker acts, you answer.

Who can sign, and how it gets validated

Corporations

A corporate officer signs, and the broker must verify that officer’s authority — typically through a corporate certification, board resolution, or an officer list. A purchasing manager or logistics coordinator generally cannot bind the company unless formally delegated.

Partnerships and LLCs

A general partner or authorized member signs. Partnership POAs are limited to two years by regulation, so they need renewal more often than corporate ones.

Sole proprietors

The owner signs personally, which also means personal liability for duties and penalties.

Brokers are required to verify the identity of the grantor under CBP’s broker regulations. If a broker accepts your POA without asking for any verification, that is a warning about how they handle the rest of your compliance.

Terms worth reading before you sign

Duration and revocation

Corporate POAs can be open-ended. If you switch brokers, revoke the old POA in writing — an unrevoked POA leaves a former broker technically able to transact in your name. Keep a register of which brokers hold active POAs.

Sub-agency clauses

Many POAs let the broker appoint sub-agents at other ports. That is practical for nationwide coverage, but it means firms you never selected may file under your name. Ask who those sub-agents are.

Terms and conditions incorporated by reference

The POA is often paired with the broker’s terms and conditions, which typically limit the broker’s liability to a nominal amount per entry and shift indemnity to you. This is where a classification error that costs you six figures becomes your problem, not theirs.

Payment and the duty-flow question

If you pay duties to the broker and the broker remits to CBP, you carry the risk that the broker fails to remit. Paying CBP directly through ACH removes that exposure. Given what your customs bond guarantees, this is worth a conversation.

Practical governance for Florida importers

Keep a signed copy of every POA you have granted, with dates. Review annually, revoke what is unused, and confirm your broker’s terms have not changed. Pair the POA with a written standard operating procedure covering classification, valuation, and origin, so the broker is filing against your instructions rather than improvising — our notes on HS code mistakes and who does what among forwarders, 3PLs, and brokers are a reasonable starting point.

If you are moving freight through PortMiami or MIA, align the POA with the rest of your logistics file — bond, ISF filer, customs clearance, and drayage instructions should all name the same responsible parties.

Frequently asked questions

Does a customs power of attorney transfer liability to my broker?

No. The POA authorizes the broker to act as your agent, but you remain the importer of record and stay responsible for the accuracy of every declaration filed in your name.

How long does a customs power of attorney last?

Corporate powers of attorney can be granted without an expiration date, while partnership powers of attorney are limited to two years. Either can be revoked in writing at any time.

Do I need to revoke an old POA when I change brokers?

Yes. An unrevoked power of attorney leaves the former broker technically authorized to transact customs business in your name. Revoke it in writing and keep the confirmation on file.
