A customs bill isn't automatically correct, but “customs fee” can describe several different charges. A government duty or import tax follows a different dispute process from a carrier's brokerage or handling fee.
For a shipment entering the United States, start by getting an itemized invoice and the underlying entry information. Ask the seller, carrier, or customs broker to correct clear errors in writing. If the problem is a CBP decision, an eligible party may need to file a formal protest. A credit-card billing dispute is a separate option and doesn't replace a customs protest.
This guide covers U.S. imports. Other countries use different forms, agencies, and deadlines.
First identify who charged you
| Charge on the bill | What it may represent | First place to dispute it |
|---|---|---|
| Customs duty or import tax | A government assessment connected to the entry | Carrier or broker for the entry details, then the eligible importer or agent |
| Brokerage, disbursement, entry, or handling fee | A private charge for clearance or advancing funds | Carrier or broker billing department |
| Import amount collected at checkout | A seller's collection or prepaid shipping arrangement | Seller, using the order terms |
| Duplicate or already-paid charge | A billing error involving the seller or carrier | The party that charged you, followed by your card issuer if appropriate |
A carrier may show government charges and its own fees on the same invoice. CBP says courier and express shipments are usually expedited through CBP by a customs broker hired by the commercial service in its Internet Purchases guidance. That broker relationship doesn't mean every line on the carrier's invoice is a CBP charge.
How to dispute a customs bill step by step
1. Save the bill and record every date
Download the invoice and save the email or delivery notice. Record:
- The date you first received the bill
- The payment due date
- The delivery date
- The date you contacted the seller, carrier, or broker
- Any liquidation or reliquidation date shown on customs records
These dates serve different purposes. A carrier's payment deadline isn't necessarily the deadline for a CBP protest. If you paid by credit card, the billing-error clock can also begin with the first statement containing the disputed charge.
2. Request the entry details
Don't dispute only a total amount. Ask for the records used to calculate it:
- Tracking number, air waybill, or invoice number
- Customs entry number
- Whether the entry was formal or informal
- CBP Form 7501, if one was issued, or the equivalent entry record
- Declared value and currency
- Product description and quantity
- HTSUS classification used for each item
- Country of origin
- Duty, tax, and other government amounts
- Brokerage, advancement, disbursement, and handling charges
- The name of the importer of record
- Shipping terms and proof of any duty or tax paid at checkout
Not every consumer shipment will have the same paperwork. If the carrier says Form 7501 doesn't apply, ask what entry record it used instead. CBP's guidance distinguishes different ways that internet purchases and courier shipments are entered.
3. Compare the entry with the actual order
Look for a specific mismatch rather than arguing that the bill “seems too high.” Common issues include:
- The same duty or tax was charged twice
- The seller already collected the amount at checkout
- The declared price, currency, quantity, or product description is wrong
- The classification appears inconsistent with the product's materials, function, or construction
- The stated country of origin is incorrect
- A private carrier charge was added even though the order or shipping terms said it was prepaid
- A carrier applied the wrong account, tracking number, or fee category
A difference between the amount you paid at checkout and the customs value isn't automatically an error. Ask the broker to explain how the value was calculated before claiming that it is wrong.
Don't ask a seller or broker to use a lower value, a false description, or an inaccurate country of origin. Submit the actual invoice and accurate product information.
4. Send a written correction request
Use the carrier's official website, account portal, or contact information on the invoice. State the exact line you dispute, the reason, and the result you want.
Ask the carrier or broker to confirm:
- Whether the disputed amount is a government assessment or a private fee
- Whether it can correct or amend the entry
- Whether it will issue a revised invoice or refund
- Which terms or policy apply to a carrier-only fee
- Whether payment before review affects the dispute
If the seller promised that duties were included, contact the seller as well. CBP cannot enforce a seller's checkout promise about who should bear a private shipping charge.
5. Escalate through the correct channel
Use the route that matches the problem:
- Incorrect CBP assessment: Determine whether the importer of record or an authorized agent can file a CBP protest.
- Carrier or broker fee: Escalate to the carrier's billing supervisor or formal claims team.
- Seller's prepaid-duty promise: Request a merchant refund under the order terms.
- Credit-card billing error: Send the issuer a written billing-error notice within the applicable deadline.
- Complex classification, penalties, or restricted goods: Consider advice from a qualified customs professional before filing.
A customer-service ticket to DHL, FedEx, UPS, or another carrier is not automatically a formal CBP protest.
Evidence that makes a dispute stronger
Organize one folder with the original documents and a short explanation of the error.
| Issue | Useful evidence |
|---|---|
| Wrong declared value | Final invoice, payment record, purchase order, and seller correspondence showing the actual transaction |
| Wrong quantity or description | Order confirmation, packing list, photographs, product specifications, and manuals |
| Classification question | Product materials, function, dimensions, construction details, and the classification used by the broker |
| Incorrect origin | Manufacturer or seller statement and available production or origin records |
| Duplicate or prepaid charge | Checkout receipt, card statement, order terms, and both invoices |
| Carrier-only fee | Itemized carrier bill, applicable terms, account records, and correspondence |
| Broker data-entry error | The original information sent to the broker and the resulting entry or invoice |
Keep the original files unchanged. Highlight the disputed line on a copy and label each attachment. Remove unrelated personal information before sharing documents, but leave the transaction details needed to identify the shipment.
Challenging the customs duty itself with CBP
A CBP protest is a formal challenge to a decision made by U.S. Customs and Border Protection. It is different from asking a carrier to waive a brokerage fee.
Under 19 CFR 174.12, a protest for covered entries generally must be filed within 180 days of the applicable liquidation or reliquidation date. Liquidation is the customs process that finalizes an entry. It isn't necessarily the date your package arrived or the date the carrier sent its invoice.
Before relying on the 180-day period:
- Ask the broker or importer of record for the liquidation status and date.
- Confirm that the disputed issue is a CBP decision eligible for protest.
- Confirm who is entitled to file and whether an authorized agent is needed.
- Read the current filing requirements in the regulation and CBP instructions.
- Identify the exact entry, item, duty amount, and requested correction.
- Attach records supporting the factual and classification basis for the claim.
- Keep proof of filing and monitor the response.
The regulation identifies CBP Form 19, or a form of the same size clearly labeled “Protest,” along with filing and content requirements. Don't assume that an email to the carrier, broker, or seller protects the CBP deadline.
If you aren't the importer of record, your ability to file may depend on the entry and your legal role in the transaction. Ask the seller, broker, or importer of record to confirm who will handle a formal protest. For a large claim, a complicated classification, or a penalty, professional customs advice may be worthwhile.
Disputing a carrier or broker fee
A carrier-only fee is usually handled through the carrier's billing process, not through CBP. The carrier's invoice and applicable terms are central to this dispute.
Your written request should ask the carrier to:
- Separate government duty or tax from private service fees
- Explain each fee and how it was calculated
- Identify the terms in effect when the shipment was accepted
- Correct any tracking, account, value, or service error
- Confirm whether a refund, credit, or revised invoice will be issued
Don't rely on a supposed universal 15-day appeal window. Carrier procedures differ, and the relevant deadline may appear on the invoice, account agreement, or service terms. Dispute the charge as soon as you notice it.
If the shipment is still being held, ask what will happen while the invoice is reviewed. If paying is necessary to avoid a delivery or return problem, ask the carrier in writing whether payment affects its review and keep the receipt. That answer depends on the carrier's terms.
Using a credit-card billing dispute
A card dispute can address a charge that was unauthorized, duplicated, or different from what the merchant agreed to provide. It doesn't decide whether CBP used the correct tariff classification or customs value.
The Federal Trade Commission's credit-card guidance says that written notice of a billing error should reach the card issuer within 60 days after the first statement containing the error. The issuer generally must acknowledge the complaint within 30 days unless it has already resolved it, and generally must resolve the dispute within 90 days.
When writing the issuer:
- Identify the merchant shown on your statement
- State the exact amount and date
- Explain the mismatch in one or two sentences
- Attach the carrier invoice, checkout receipt, and correspondence
- Send the notice using the issuer's billing-dispute instructions
- Keep a copy and proof of delivery
The 60-day process described by the FTC is for credit-card billing errors. Don't automatically apply it to a debit card, prepaid card, bank transfer, or peer-to-peer payment. A card issuer may also ask for evidence that the charge was not as agreed; a dispute isn't a guaranteed refund.
Customs dispute letter template
Use this version for the seller, carrier, or broker. It is not a substitute for the official CBP protest process.
Subject: Dispute of customs invoice [invoice number] for tracking [tracking number]
[Your name]
[Address]
[Email and phone]
[Date]
[Seller, carrier, or broker]
[Billing or claims department]
I dispute the charge of [amount] shown on invoice [number], issued on [date], for tracking number [number].
The specific problem is:
[Describe the error. For example: the amount was already paid at checkout; the declared value does not match the attached invoice; or the carrier added a fee that I cannot identify.]
Please confirm in writing:
1. Which part of the amount is government duty or tax;
2. Which part is a carrier or broker fee;
3. The customs entry number and entry details;
4. The classification, country of origin, declared value, and calculation used; and
5. The correction, credit, or refund available.
I have attached [list documents]. Please place this dispute on the account and send me a written decision.
This request concerns [the customs assessment, the private carrier fee, or both]. I reserve the right to pursue the appropriate review process for each part of the charge.
Sincerely,
[Your name]Deadlines and limits to keep separate
| Dispute | Deadline or limit to check |
|---|---|
| CBP protest | Generally 180 days from the applicable liquidation or reliquidation date for covered entries under 19 CFR 174.12 |
| Credit-card billing error | Written notice should reach the issuer within 60 days after the first statement containing the error |
| Carrier-only fee | The invoice, account agreement, or carrier policy may control; dispute it promptly |
| Seller refund | The order terms and the seller's refund process control |
A request for a carrier review doesn't automatically extend the CBP protest period. Calendar the customs deadline separately while the carrier investigates.
Import holds and regulated goods
A duty correction won't remove every import problem. CBP notes that imports must meet applicable requirements from agencies such as the Food and Drug Administration, Consumer Product Safety Commission, and Animal and Plant Health Inspection Service in its Customs Duty Information.
If the shipment is held because of a safety, food, plant, animal, alcohol, or other regulatory issue, focus on the agency requirement as well as the amount charged. Don't mislabel the goods to speed release.
Common questions
Can CBP refund a carrier's brokerage fee?
A CBP protest addresses an eligible CBP decision. It doesn't automatically determine whether a private carrier or broker fee was correct. Dispute that line with the carrier or broker under the applicable terms.
Does contacting the carrier stop the customs deadline?
Don't assume it does. A support case and a formal CBP protest are different actions. Get the liquidation date and protect the applicable deadline independently.
Can the recipient file a CBP protest?
It depends on the entry, the importer's role, and whether the person is an eligible party or authorized agent. Ask the importer of record or broker who will file before the deadline passes.
What if the invoice has no entry number?
Ask the carrier or broker for the entry number, entry type, and equivalent customs record. The absence of information isn't proof that the bill is fraudulent, but you should understand what you are being asked to pay before treating the amount as correct.
Start by saving the invoice, order confirmation, and payment record today. Then request the entry details in writing and calendar both the carrier's response deadline and any separate CBP or credit-card deadline that applies.
