Customs Power of Attorney: CBP Form 5291 Explained

November 8, 2026

Reviewed by Sasha Božič, Licensed Customs Broker

A customs power of attorney (POA) authorizes a licensed customs broker to transact customs business in your name. CBP Form 5291 is the standard form, though brokers often use their own version with the same content. A broker needs a valid POA from the importer before filing anything for them, and has to keep it on file. You can give a POA to more than one broker, for different work.

Who signs it

An officer or other person authorized to bind the importing company. Brokers are required to verify who you are before they accept it.

What it can cover

  • Filing entries and entry summaries.
  • Filing corrections, such as post-summary corrections.
  • Filing protests and drawback claims.
  • Signing related documents on your behalf.

Many importers give their entry broker one POA and give a recovery specialist another, so each handles its own work.

How long it lasts

A POA stays in effect until you revoke it, unless it states an end date. Revocation is in writing to the broker.

Frequently asked questions

Does giving a second POA affect my current broker? No. Several brokers can hold POAs for different work at the same time.

Do I give up control of my refunds? No. Refunds go to the importer of record. See importer of record responsibilities.
