For a package delivered to the United States, the strongest proof of customs fees paid is an itemized customs or carrier receipt tied to the shipment. It should show the tracking or entry number, amount, date, payer, and a paid status or transaction reference.

A bank statement can confirm that money left your account, but it usually doesn't explain whether the payment was duty, brokerage, handling, sales tax, or something else. A CN22 or CN23 customs declaration shows what the sender reported; it doesn't, by itself, prove that a fee was paid.

First identify who charged you

“Customs fees” can describe several different charges. The right evidence depends on the organization that collected the money.

Charge Best supporting evidence What it establishes
U.S. customs duty or government assessment Customs receipt, broker entry and payment record, or an itemized carrier invoice linked to the entry The amount assessed and the shipment involved
Carrier brokerage, advancement, or handling charge Carrier invoice plus payment confirmation That the carrier's service charge was paid
Seller-collected import amount Order invoice, checkout terms, and payment confirmation What the seller charged or promised to cover
Card, bank, or ACH payment Statement showing merchant, date, amount, and transaction reference, paired with the underlying invoice That a payment was made, but not necessarily what it covered

A courier or customs broker may pay or advance an amount during the entry process and then bill you. In that situation, the carrier's paid invoice is useful evidence of what you paid the carrier. If you need proof of the underlying customs assessment, request the entry number and payment record from the carrier or broker.

Documents that do and do not prove payment

Customs receipts and broker records

A receipt that identifies the shipment and says “paid” is usually the clearest consumer record. For a formal U.S. entry, a broker may provide an entry summary such as CBP Form 7501. It can show the declared value, classification, and duty calculation, but it isn't automatically proof that you personally paid. Pair it with a receipt, account ledger, or bank record.

Consumers don't receive a formal entry summary for every online purchase. The document depends on the shipment's value, transport method, goods, and entry process.

CN22 and CN23 forms

Postal shipments commonly use CN22 or CN23 forms to declare the contents, value, and other customs information. U.S. Customs and Border Protection says sellers should attach a completed CN22 or CN23 to help an international package move through examination. See CBP's Internet Purchases guidance.

These forms help match a charge to a package, but they are declarations rather than payment receipts. A form with a declared value of $100 doesn't prove that a particular duty or carrier fee was paid.

Commercial invoices and packing lists

A commercial invoice, order confirmation, and packing list support the value and description of the goods. They can help show that a duty calculation used the wrong price, quantity, or product description.

They don't prove payment unless they also include a payment confirmation. An invoice marked “amount due” is evidence of a bill, not a paid charge.

Bank and ACH records

A posted card, bank, or ACH transaction is useful when it matches the shipment and invoice. Look for the merchant or carrier name, transaction date, amount, currency, and reference number.

An ACH debit without a matching customs or carrier document is incomplete proof. It shows a transfer occurred, but not whether it covered duty, shipping, a deposit, or another charge. Don't send a full bank statement if a redacted transaction line will do.

Tracking messages and clearance status

A tracking status such as “customs cleared” or “released” can show that the carrier completed an entry step. It doesn't necessarily prove that every charge connected with the shipment was paid by you.

Likewise, an email or text with a customs logo isn't proof that the request is genuine. Verify the shipment through the carrier's official website or account before paying.

How to verify a customs payment request

  1. Match the shipment. Check the tracking number, recipient, sender, package description, and declared value. A genuine-looking invoice for a different tracking number is not relevant.
  2. Request an itemized bill. Ask the carrier or broker to separate government duty or tax from brokerage, advancement, storage, delivery, and other service charges.
  3. Check who is responsible for the charge. Review the seller's checkout page, invoice, and shipping terms. “Duties and taxes included” may mean the seller collected an import amount, but you should ask whether it was an estimate or an amount already paid to the carrier or customs authority.
  4. Use a verified payment route. Open the carrier's website by typing the address yourself or use the payment function inside your existing account. Don't rely only on a payment link in an unexpected message.
  5. Save the complete record. Download the invoice, receipt, payment confirmation, and any entry reference. Keep the original digital files, not just a screenshot.

If the request asks you to pay through an account that cannot be verified, contact the carrier using the phone number or website listed on its official site. Don't send money or identity documents to an unverified contact.

What to do if you were charged twice

First confirm that the earlier transaction is posted rather than a pending card authorization. Then compare both demands using:

If both payments relate to the same shipment, contact the party that issued the second bill and provide the first receipt. Ask whether the payment was applied to the same entry and request written confirmation of any duplicate-payment review.

If the seller collected duties at checkout but the carrier later billed you, send the seller the checkout terms and the carrier's invoice. Ask the seller to explain who was supposed to pay and whether its collected amount was remitted. Don't assume that a seller's “import fees” line is the same as a customs receipt.

For a payment you didn't authorize, contact your bank or card issuer promptly through its official number and ask about its fraud and transaction-dispute process. Keep the carrier invoice and message that led to the payment.

How to challenge an incorrect or unclear amount

Payment proof alone doesn't show that a duty calculation was correct. To request a review, gather:

Start with the carrier or broker that issued the bill. Ask which company filed the entry, who is listed as the importer of record, and what correction or refund process applies. If the problem is a wrong product description or value, provide the original records rather than editing the declaration yourself.

If the seller's shipping terms promised prepaid import charges, raise the issue with the seller as a billing or contract question and attach the relevant terms. A refund from a seller, carrier, or customs authority follows that party's applicable process; one payment receipt doesn't guarantee a refund.

Why the shipment type matters

CBP's Internet Purchases page says purchases valued below $2,500 may, in many cases, enter as informal entries. “Informal” describes an entry process, not a promise that the package is duty-free or that no carrier charge will apply.

International mail and courier shipments can also produce different records. A courier or express company often uses a customs broker, while postal packages may carry a CN22 or CN23 declaration. Ask the party handling the shipment for the document that connects the charge to the entry.

Customs payment is only one part of import compliance. CBP's Customs Duty Information notes that other U.S. agency requirements may apply, including rules enforced by the Food and Drug Administration, Consumer Product Safety Commission, or Animal and Plant Health Inspection Service. A paid receipt doesn't prove that goods meet those separate requirements.

Records to keep

Save this set of documents until the package is delivered and any billing, refund, or dispute is closed:

If you import for a business, separate recordkeeping and entry obligations may apply. This guidance focuses on personal online purchases entering the United States.

Common questions

Is a bank statement enough to prove customs fees were paid?

Usually not. It proves that money left your account, but it may not identify the shipment or explain the charge. Pair it with an itemized customs or carrier invoice and a payment confirmation.

Does a CN22 or CN23 prove that duty was paid?

No. It supports the contents and declared value of a postal shipment. Use a receipt, paid carrier invoice, or customs payment record to prove payment.

Do I need CBP Form 7501 for every imported package?

No. A formal entry summary may be used for some entries, but consumers don't receive one for every online purchase. If a broker gives you one, check it against the payment record.

What if the seller says import fees were included?

Keep the order page and terms showing that promise. Ask the seller whether it prepaid the actual charge or collected an estimate, then ask the carrier to identify any unpaid entry amount. Request an itemized explanation before paying twice.

Does “customs cleared” mean I paid all customs fees?

Not necessarily. It may describe the shipment's release status rather than the payment of every duty, tax, or carrier service charge.

This guidance is for goods entering the United States. Fees and proof requirements for imports entering the EU, China, Canada, or another country can differ, so use that destination's customs authority and carrier records instead.
