Yes, but the correct refund route depends on who imposed the charge. A U.S.-bound package invoice may combine a government customs assessment with the carrier's brokerage or advancement fee. A seller may also have promised to cover import costs.

Start by separating those amounts. A request to the carrier won't replace a formal customs appeal, and a CBP refund request generally won't remove a private carrier fee.

This guide focuses on shipments entering the United States. Deadlines and appeal procedures in other countries are different.

What customs charges can you dispute?

The label “customs fee” isn't enough to identify the right process. Ask for a line-item breakdown before disputing the full balance.

Step 1: Request a complete breakdown

Ask the carrier or customs broker for:

• The amount attributed to duty, tax, or another government charge
• Each brokerage, handling, advancement, or disbursement fee
• The customs entry or declaration reference, if one exists
• The declared value, currency, quantity, and country of origin
• The tariff classification or HTS code used, if available
• The name of the importer of record
• Whether the carrier has already paid the government amount on your behalf
• The deadline for payment, correction, or review

Some personal shipments use simplified or informal entry procedures and may not have the same records as a commercial import. If the carrier can't provide a formal entry summary, ask what type of entry was used and which review process applies.

Keep the invoice, tracking page, delivery notice, and all emails. Use the phone number or website printed on the carrier's invoice rather than responding to an unexpected message requesting bank details.

Step 2: Check the information used to calculate the bill

Compare the carrier's information with your order records and the seller's commercial invoice.

Look for:

• A declared value that doesn't match the price you paid
• The wrong currency or a duplicated quantity
• A product description that doesn't match the item
• An incorrect country of origin
• A tariff classification that appears inconsistent with the product's material, construction, or use
• A carrier fee that appears twice or was never disclosed
• A seller promise that duties were included at checkout

A product name alone may not establish the correct tariff classification. Product specifications, photographs, material details, model numbers, and manufacturing information are more useful.

If the seller supplied an incorrect invoice, request a corrected commercial document. Don't ask the seller to create a false low-value invoice or change the origin after the fact. Inconsistent documents can make a customs review harder.

An online duty calculator, seller estimate, or another shipment's bill can help identify a possible error, but it doesn't by itself override the official customs record.

Step 3: Send the dispute to the right party

If the carrier added the fee

Use the carrier's billing-dispute process. State which line item you dispute and ask the carrier to explain the contractual basis for the charge. If the carrier collected both the government assessment and its own fee, ask it to identify how much was remitted to customs and how much it retained.

If the seller promised to cover import costs

Send the seller the invoice and the relevant checkout language. Terms such as “duties included” or “duties paid” may support a reimbursement request against the seller, but they don't automatically change the customs assessment. The seller and the customs authority are separate parties.

If the government assessment appears wrong

Ask the carrier or broker who filed the customs entry and whether it can request a correction. The person receiving a package isn't always the importer of record or the person authorized to file a formal customs protest.

Use the filing instructions on the customs notice or entry record. A carrier's customer-service complaint generally doesn't pause a customs deadline, so don't wait for a billing investigation if an official filing period is close.

How to challenge a U.S. customs decision

A formal customs appeal is different from disputing a courier invoice. First identify the document involved:

1. Find the ruling, notice, entry record, or other customs determination.
2. Confirm the importer of record and any authorized broker or representative.
3. Identify whether the issue concerns classification, value, origin, or another determination.
4. Gather evidence tied to that issue.
5. Follow the filing method and deadline stated in the official notice.
6. Keep proof of submission and copies of every attachment.

CBP's published appeal procedures describe different time limits for different actions. They include:

• Appeals of a ruling filed within 30 calendar days after the ruling is issued
• Certain appeals filed within 45 days after the effective date of the notification
• Administrative review for qualifying USMCA origin determinations by exporters or producers in Canada or Mexico, with a protest filed within 90 calendar days after liquidation

Those periods aren't a universal deadline for every consumer package or carrier invoice. Don't copy a 30-, 45-, or 90-day period onto your case without checking the specific notice and entry status.

For a high-value shipment or a technical classification or valuation dispute, a licensed customs broker or customs attorney can help identify the correct filing route. This is general information, not legal advice.

How an approved CBP refund is paid

Getting a customs decision changed and receiving the money are separate steps.

CBP's ACH Refund instructions state that, effective February 6, 2026, corporations and individual payees with an ACE Portal account must use the ACH Refund Authorization tab in the ACE Secure Data Portal.

The same instructions say that, when applicable, a third party designated on CBP Form 4811 must also have an ACE Portal account and complete the ACH refund enrollment process. If an importer seeks a waiver, CBP says the importer must show that the circumstances meet the waiver criteria in 31 CFR 208.4. A written waiver request must identify the importer, the pending refund, and the specific waiver provision being relied on.

These instructions concern the payment of an approved CBP refund. They don't determine whether a carrier's brokerage charge should be returned. If a carrier collected the money from you, ask whether the refund will come from the carrier or from CBP and request the applicable claim reference.

Don't confuse a refund request with duty drawback

Businesses sometimes use the term duty drawback for a separate customs program involving eligible imported merchandise that is later exported or destroyed, or used in products that are exported. It requires specific records and eligibility analysis.

Drawback isn't the ordinary remedy for an incorrect charge on a personal package. It also doesn't replace a correction or protest when the original customs assessment used the wrong value or classification. Businesses with repeated imports and exports should verify current CBP requirements before relying on drawback calculations.

What to do if the dispute is denied

If the carrier or seller rejects your request:

• Ask for the denial and the reason in writing.
• Request the exact invoice line, entry information, or contract term supporting the decision.
• Separate any valid government charge from a disputed carrier or seller charge.
• Check the official customs notice again for an appeal or protest route.
• Ask your card issuer what billing-dispute process applies if the issue is an unauthorized carrier service charge. A card dispute doesn't decide whether customs duty was legally owed.
• If the package is being held, ask about storage, return, or disposal consequences before refusing delivery.
• Consider professional customs help if the amount is substantial or the dispute involves classification, valuation, origin, or a missed filing deadline.

FAQ

Can I dispute customs fees after paying them?

Often, you can still request a carrier, seller, or customs review, but the route and deadline depend on the charge. Paying the invoice doesn't turn a carrier fee into a customs assessment or eliminate the need for evidence. Ask for a written refund procedure as soon as you identify the error.

Is a carrier's brokerage fee the same as customs duty?

No. Customs duty is assessed under the customs entry, while brokerage, advancement, and handling charges are typically billed under the carrier's service terms. A single invoice may contain both.

Will the seller's promise to pay duties guarantee a CBP refund?

No. It may support a reimbursement request against the seller, but it doesn't automatically change the customs record. Request a correction from the party that made the error and use the official customs route if the assessment itself is wrong.

What evidence is most useful?

Keep the order confirmation, payment receipt, commercial invoice, packing list, carrier invoice, tracking record, customs notice, entry reference, product specifications, origin information, and written communications. Highlight the exact mismatch instead of sending a large unorganized file.

What should I do first?

Request a line-item breakdown and the customs entry or declaration reference. Then compare the value, currency, quantity, origin, classification, and carrier fees with your records. That determines whether your next message should go to the carrier, seller, broker, or customs authority.
