You can challenge both parts of a customs bill: the government duty and the broker's service charge. They are not the same fight. Different office, different rules, different clock. The templates below cover U.S. CBP, HMRC, EU national customs authorities, and the Australian Border Force. Use them as a starting point, then match the form, deadline, and evidence to whoever billed you.
Split the Bill Before You Write
A customs authority owns duty, tax, classification, valuation, and origin. A broker owns its own service fee. If you send a CBP protest to a broker, the brokerage invoice won't change. If you complain to a broker about a duty decision, the government decision won't move. The controlling law or policy depends on who sent the bill.
| Bill or decision | Who handles it | What to use |
|---|---|---|
| Government duty, VAT, GST, classification, valuation | Customs authority | Formal protest, repayment claim, appeal, or refund application |
| Brokerage or handling fee | Broker or freight forwarder | Contract, invoice dispute, customer service escalation, regulator if needed |
| Courier disbursement fee | Courier | Courier's dispute process |
If the notice says "customs fees" but part of the amount is a courier disbursement fee, split the bill before you write.

Re: Dispute of customs fees - Entry/Package No. [Number], Invoice [Number], Amount disputed: [Amount]
Dear Sir or Madam,
I am writing to dispute the customs duties or brokerage fees assessed on this import. The total amount in question is [amount].
Import details:
- Description: [goods]
- Declared value: [amount]
- Date of import: [date]
- Port or clearance location: [location]
- Entry, waybill, or reference number: [number]
Reason for dispute:
1. [Incorrect valuation. The invoice value is [amount], not [assessed amount].]
2. [Wrong classification. The correct code should be [code], not [code].]
3. [Broker error or fee not agreed in the contract.]
I have attached [invoice, receipt, packing list, photos, payment proof, or expert valuation]. I request a refund of [amount] and a written decision. If interest is available under the relevant rules, please include it.
Thank you for your review. Please contact me if you need more information.
Sincerely,
[Your Full Name]
[Signature]United States: CBP Protest Letter
U.S. importers challenge CBP decisions through a protest under 19 U.S.C. 1514. For entries made on or after December 18, 2004, the deadline is 180 days after liquidation, per 19 CFR Part 174. File CBP Form 19 or its ACE electronic equivalent.
A protest filing guide notes decisions often take 60 to 180 days. Late filings are jurisdictionally barred. CBP cannot extend the date or accept them.

Re: Protest - Entry No. [Number]
Dear Port Director,
I protest the duty assessment on Entry No. [Number] under 19 U.S.C. 1514. The assessed value was [amount]. The correct value is [amount], based on the attached commercial invoice and payment records.
The classification should be [code], not [code]. The duty paid was [amount]. I request reliquidation and a refund of [amount].
Attachments: [list documents]
Sincerely,
[Name]UK: HMRC C285 and BOR286
In Great Britain, overpaid import duty and VAT claims use form C285. For goods delivered by Parcelforce or Royal Mail, use BOR286. HMRC aims to decide within 30 days, according to official guidance. Northern Ireland claims follow the Union Customs Code, not the GB rules. Attach C79 or payment proof.
Subject: Dispute import fees - C79 reference [number]
Dear HMRC,
I am disputing [GBP amount] in import duty and VAT on parcel [ID]. The invoice value was [GBP amount], but the charge was based on [GBP amount]. I have attached the invoice, C79 certificate, and payment proof.
Please review the valuation and refund the overpayment under the C285 process.
Regards,
[Name]EU: National Authorities and the UCC
Repayment and remission claims go to the national customs authority. The European Commission explains the framework. Each member state runs its own portal or form. Deadlines depend on the legal ground. One German state portal lists 90 days for an invalidated declaration, up to one year for rejected goods, and three years for duties not due.
Subject: Repayment claim - Declaration [number]
Dear Customs Authority,
I request repayment of [EUR amount] in customs duty on declaration [number]. The duty was assessed on [amount], but the correct value is [amount] according to the attached invoice.
The legal ground is [invalidated declaration / rejected goods / duties not due / post-clearance recovery]. I have attached [documents].
Please confirm receipt and provide a written decision.
Sincerely,
[Name]Australia: Refund Reasons and Reason Codes
Australia's Customs Act 1901 limits refunds unless you fit a prescribed refund reason under the Customs Regulation 2015. A freight guide explains that forwarders quote the correct reason code in the refund application. Importers self-assess tariff classification, so a wrong code is a common problem. Check the ABF process before you send anything.
Subject: Customs duty refund request - TPN [number]
Dear Australian Border Force,
I request a refund of [AUD amount] in customs duty on shipment [number]. The duty was assessed under tariff classification [code]. The correct classification is [code], which carries a lower rate.
Attachments include invoice, packing list, payment proof, and tariff classification evidence.
Sincerely,
[Name]Brokerage Fees Are a Separate Fight
Turns out, a broker isn't customs. It charges for filing, handling, disbursements, and sometimes storage. Your leverage comes from the contract and the invoice, not customs law. Ask for an itemized invoice. If the fee wasn't authorized, dispute it in writing and request a refund. If the broker won't budge, check the contract for an escalation clause or see whether a transport regulator covers the company.
Subject: Refund request - overcharged brokerage invoice [number]
Dear [Broker],
I am disputing the [amount] fee on invoice [number]. The invoice does not match the quote and includes [item] that I did not authorize. Please send an itemized breakdown and refund [amount].
If we can't resolve this, I will escalate through [contract clause or regulator].
Regards,
[Name]Evidence and Deadlines That Matter
Deadlines and evidence shift by country and legal ground. The table is a starting point, not a substitute for the notice.
| Region | Main route | Deadline to check | Evidence that helps |
|---|---|---|---|
| US | CBP protest, Form 19 or ACE | 180 days from liquidation | Invoice, entry summary, payment proof, classification evidence |
| UK | HMRC C285, BOR286 for Royal Mail/Parcelforce | HMRC aims to decide in 30 days | C79, invoice, payment proof, correction details |
| EU | National customs authority repayment/remission | Depends on ground; verify with authority | Declaration, invoice, proof of duty paid, legal ground |
| Australia | ABF refund application with reason code | Check current ABF rules | Invoice, TPN, payment proof, classification evidence |
Mistakes That Sink Otherwise Good Claims
The first mistake is sending the letter to the wrong party. The second is missing the deadline. Thing is, a vague dispute rarely wins. "I was overcharged" won't work. You need the number, the correct number, and the paper that proves it, and if you don't have that paper, get it before you file, because the agency won't go looking for it. Don't cite another country's law. Don't demand a refund before you've paid if the shipment is still held, unless the authority gives you a different route. Don't assume a broker's fee is refundable just because the duty was refunded.
Questions That Still Come Up
Can I dispute a customs fee before paying it? Usually if the shipment is held, paying is the practical way to get release. Some routes allow deposits or post-clearance claims. Check the authority.
What if the deadline passed? Late filings are often barred. Ask the authority if any administrative exception applies. Don't count on it.
Do I need a lawyer? Most small refund claims don't require one. You may want help if the amount is large, the classification is technical, or CBP denies a valid protest.
Can I use one letter for customs and broker fees? No. They're separate. Send separate letters with separate evidence.
Open the customs notice and find the entry, waybill, or declaration number. That number decides which form and which deadline apply. Then pick the sample above, attach the invoice and payment proof, and send it through the route that matches the bill. This is general information, not legal advice.
