A surprise "customs" line on a delivery notice is often two charges sitting on top of each other. One may be a U.S. duty. The other is frequently a carrier brokerage or advancement fee.
Can you fight the duty if the number looks wrong?
You protest a CBP decision after the entry liquidates, using the administrative process in 19 CFR Part 174, not a help-desk ticket. Carrier chat doesn't start it.
Thing is, a lot of people burn the 180-day window while they argue with the seller about who should have prepaid the duty. Don't wait on the seller's chat.
Duty versus the courier's own fee
CBP decides classification, value, and the duty on the entry. Couriers add their own clearance fees on a separate invoice more often than shoppers expect.
A protest targets the agency decision. It will not wipe a handling surcharge by itself.
Start with the carrier's billing team when the ugly number lives only on a courier invoice. Wrong duty or entered value on the CBP paperwork is a protest issue.
| Bill you actually have | Who owns the decision | What to file |
|---|---|---|
| Duty or liquidation on the CBP entry | U.S. Customs and Border Protection | Protest after liquidation |
| Brokerage, disbursement, or advancement fee | The carrier or its broker | Carrier billing dispute |
| A seller promise of prepaid duties | The merchant's checkout terms | Refund request to the seller |
When a U.S. protest is even on the table
You challenge a CBP decision, usually the liquidation of the entry. A tracking update is not that decision.
CBP's protest page says filings are generally made on CBP Form 19 through a protest filer account in the ACE Portal. Paper at the same port still works.
The statute does not strictly require that exact form.
For entries made on or after December 18, 2004, the protest window is 180 days after the decision, and a liquidation protest belongs after liquidation, not before. Keep the entry number with the file.
Filing the protest
- Confirm the entry liquidated and write down that date. The 180 days run from CBP's decision, not from delivery.
- Open a protest filer account in ACE if you'll file online. Paper still belongs at the port that issued the decision.
- Name the issue in ordinary language: classification, appraised value, origin, or the amount of duty assessed.
- Attach the invoice, packing list, transport document, entry summary, and a short calculation of the correct figure.
- Submit once and save the confirmation.
CBP's protest page does not promise a refund-by date. Budget months, not a week.
Papers that actually help
A usable protest shows the invoice price, the entered value, and why those figures diverge. Rants about unfair fees don't.
Bring these if you have them:
- Commercial invoice for what you paid
- Bill of lading or air waybill
- Packing list
- Entry notice with the entry number
- A short value or tariff explanation
- Proof of duty payment if you want money back
Turns out the entry number beats a polished cover letter.
People sometimes attach a screenshot of the shopping-cart total and nothing else, and then they're surprised when CBP can't match that screenshot to an entry, because the cart total may leave out freight that went on the declaration or include a coupon that never appeared on the commercial invoice the broker used.
If the import landed in the UK
Do not mail CBP Form 19 to HMRC. Great Britain uses a repayment claim.
HMRC's guide to reclaiming overpaid import duty and VAT tells you to claim with online form C285. HMRC aims to decide within 30 days.
Northern Ireland follows Union Customs Code rules, not that GB form.
Parcelforce and Royal Mail deliveries use form BOR286.
The postal customs charge is often VAT plus a handling fee, which makes the total look like one official tax when it isn't. Only the overpaid duty or VAT belongs on C285.
EU claims stay with national customs
EU repayment is not a CBP protest with extra stamps. Under the Union Customs Code, remission and repayment of a customs debt is handled by the member state that collected it, and if you paid and the related declaration is later invalidated, that duty must be repaid.
Canada, Australia, and other destinations
There is no worldwide protest form.
If CBSA or the Australian Border Force issued the bill, use that agency's own refund or review process and the import declaration they already hold. A U.S. ACE filing won't move that assessment.
After CBP says no
A CBP denial closes the administrative protest. Some importers then go to the Court of International Trade, which has its own filing clock and is not an extra button inside ACE. You're in a court process then.
Mixing a carrier refusal letter into a CBP court file just confuses the record, to be honest. If the courier denied a brokerage refund, keep that fight with the courier.
Pull the entry number and the liquidation date tonight. The entry number, not the tracking number. Decide which bill is actually wrong. If it's CBP duty and you still have time, file the protest in ACE or at the port instead of waiting on the seller's support queue. Do it while the 180 days remain.
