An unexpected import bill can mix a CBP duty with a courier fee, so the first job is to separate the lines. One charge may come from U.S. Customs and Border Protection. Another may be brokerage, advancement, storage, or delivery. The right complaint route depends on which line is wrong, and a general complaint sent to the wrong party can waste the only deadline that matters.

For U.S. imports, match each dollar on the invoice to either a government decision or a private service charge. This is general consumer information, not legal advice.

Identify the charge you are disputing

Use the charge description and entry paperwork to decide where to send the first complaint.

A CBP protest is a formal challenge to a CBP decision about an entry. It's not a general refund form for every cost tied to an international parcel.

CBP's e-commerce frequently asked questions explain that an entry can be made by the owner or purchaser, or by a licensed customs broker properly designated by the owner, purchaser, or consignee. That's why the person who receives the package may not be the person who can file the protest.

Collect the entry and billing records

Before arguing that a fee is wrong, ask the carrier, seller, or broker for an itemized explanation. Put the request in writing and keep the response. Ask for:

• The shipment or entry number
• The importer of record
• The entry summary or other customs entry record
• The liquidation or reliquidation date, if the entry has been finalized
• The tariff classification used
• The declared customs value and country of origin
• Each duty, tax, and government fee as a separate line
• Each carrier or broker service fee as a separate line
• Proof of any payment already made

For a consumer shipment, you may not receive all these documents automatically. A sales receipt by itself may not explain the customs value or classification used, so ask what information produced the assessment. Compare the answer with your order confirmation, commercial invoice, packing list, shipping label, and product description.

Check the U.S. protest deadline

The protest clock usually starts from a CBP decision, not the day you paid the driver. Under 19 CFR Section 174.12, for an entry made on or after December 18, 2004, the filing period is generally 180 days after the decision being challenged. For many entries, that's the notice of liquidation or reliquidation. Liquidation is CBP's final accounting of the duties for an entry. The regulation also covers other decision types and start dates, so don't rely on the invoice date.

If the entry was made before December 18, 2004, the regulation provides a 90-day period. Most current consumer parcels won't fall there, but the point remains: check the entry paperwork.

A carrier or broker may set its own deadline for disputing a private fee. That internal deadline is separate from the CBP protest period. If you don't know whether the entry has been liquidated, request the information immediately. For a high-value shipment, get help from a licensed customs broker or customs attorney before the period runs out.

Step-by-step dispute process

1. Preserve the paper trail

Save the original invoice, order details, product listing, payment confirmation, shipping documents, customs notices, and messages with the seller or carrier. Keep copies of anything you submit.

If you speak with customer service, follow up by email and summarize what was said. Ask the representative to identify the disputed line and give a written answer.

2. State the specific error

A strong complaint names the problem. It might say the entry used the wrong tariff classification, changed the declared value without explanation, recorded the wrong country of origin, omitted a duty preference, charged the same fee twice, or added a carrier fee that conflicts with the quoted terms.

"It's too high" is not enough by itself. State the amount charged, the amount you believe is correct, and the document that supports the difference.

3. Confirm who must file

If the issue concerns a CBP decision, determine whether you are the importer, consignee, or authorized agent of an eligible party. Under 19 CFR Part 174, the formal protest process applies to specified parties and their authorized agents.

If you're only the recipient, ask the seller, carrier, or broker:

1. Who was listed as the importer of record?
2. Has the entry been liquidated?
3. Who is eligible to file the protest?
4. Will the broker file it, or can it authorize you to do so?
5. What is the filing confirmation or reference number?

A complaint sent to a carrier may not preserve the CBP deadline unless the eligible party files the required protest.

4. Calculate the refund request

Use a simple calculation:

• Amount assessed or paid: $___
• Correct amount supported by your records: $___
• Amount disputed: $___

Explain how you calculated the difference. If only one line is disputed, identify that line rather than asking for an unexplained full refund.

5. Gather evidence that matches the issue

The evidence should answer the exact dispute. If classification is wrong, send product specifications, technical drawings, or manufacturer information. If value is wrong, send the commercial invoice, order confirmation, and payment receipt. If origin or a duty preference is the issue, send the documents that prove that claim. If the carrier added a fee, send its itemized invoice and the shipping terms.

Label attachments clearly and refer to them in the complaint. Send copies unless the recipient specifically asks for originals.

6. File a formal CBP protest when appropriate

The regulation requires a written protest against a CBP decision. 19 CFR Section 174.12 describes filing on CBP Form 19, or on a same-size form clearly labeled "Protest" that contains the required information in the required order. It also describes filing the written protest in quadruplicate.

Use current CBP filing instructions or have the importer's broker confirm where and how the submission should be filed. Keep a complete copy and proof of delivery or acceptance.

Your filing should identify:

• The person or company filing
• The entry number
• The decision being challenged
• The liquidation or other relevant date
• The facts supporting the complaint
• The legal or factual grounds for correction
• The amount of refund requested
• Every attached document
• The signature and contact information of the filer or authorized agent

A starting outline could look like this:

Subject: Protest of Entry [entry number]

I am [the importer, consignee, or authorized agent] filing a protest concerning the CBP decision for entry [number], dated [date].

Decision disputed: [classification, value, origin, duty calculation, or other decision]

Facts: The entry records show [brief explanation]. The correct information is [correct information], supported by Attachments [numbers].

Amount: CBP assessed or collected $[amount]. The supported amount is $[amount]. I request correction of the entry and a refund of $[difference], subject to CBP's determination.

Attachments: [numbered list]

Sincerely,
[Name, title, address, email, and signature]

This outline does not replace CBP Form 19 or the applicable filing requirements.

7. Dispute private carrier or broker fees separately

A CBP protest is not the normal route for a private brokerage or handling charge. Send the carrier or broker the invoice number, shipment number, specific fee being challenged, amount paid, amount requested back, shipping or sales terms you relied on, and copies of customs documents and receipts. Ask for a written explanation and final decision.

If the seller advertised duties as included, contact the seller with the order confirmation and ask it to correct the billing arrangement. If the carrier says the seller supplied incorrect information, ask for the document or data that caused the charge.

If the charge appears unauthorized or doesn't match the merchant's representation, contact the payment provider promptly and ask which billing-dispute process applies. A payment dispute doesn't decide the correct tariff classification and doesn't replace a timely CBP protest.

What happens after filing

CBP reviews a protest and may allow or deny it in whole or in part. The CBP protest rules describe the review and notice process.

If the protest is denied or partly denied:

1. Read the written decision and identify each reason for denial.
2. Check whether the facts or legal issue may qualify for further review.
3. Review the requirements in 19 CFR Section 174.24 and 19 CFR Section 174.25 before requesting further review.
4. Ask the importer's broker or a customs attorney whether another post-entry procedure or court review applies.
5. Keep pursuing a carrier or broker billing complaint separately if it concerns a private fee.

Don't assume that filing a second customer-service complaint extends a statutory deadline. For a high-value shipment, repeated classification issue, or disputed legal interpretation, professional advice may be worthwhile before the filing period expires.

Mistakes that delay or weaken a complaint

The most common error is treating the entire courier invoice as a CBP duty. Another is waiting for the seller or carrier to respond while the protest clock runs. A sales receipt alone may not address classification, origin, or customs value, and a refund request without a calculation is easy to reject.

Also avoid sending a general complaint instead of identifying the entry and decision. Don't assume the parcel recipient is automatically the eligible protest filer, and don't expect CBP to cancel a private brokerage contract. A success-rate estimate or refund promise that isn't tied to your entry doesn't prove your case.

Questions about customs fee complaints

Can an online shopper file a CBP protest?

Possibly, but eligibility depends on the person's role in the entry and the decision being challenged. Find out whether you were the importer, consignee, or authorized agent. If another party made the entry, that party or its broker may need to file.

Is the deadline 180 days from delivery?

Not usually. For many entries made on or after December 18, 2004, the relevant period is generally 180 days from the decision being protested. That often means the notice of liquidation or reliquidation, but other CBP decisions can have different triggering dates, so verify the entry record.

Can a CBP protest recover a carrier's brokerage fee?

Not normally. A protest addresses a CBP decision. Brokerage, advancement, storage, and similar charges are generally handled with the carrier or broker under the applicable billing and shipping terms.

What should I do if I don't have the entry number?

Ask the carrier, seller, or customs broker for the entry number, importer-of-record details, and entry documents. Make the request in writing and keep proof of when you asked. If the deadline may be close, seek qualified customs help rather than waiting for an informal response.

Request the itemized invoice and entry records first. Separate any CBP assessment from private carrier charges, confirm who is eligible to file, and calendar the applicable deadline before submitting your evidence.
