Customs protest: what you can contest, and by when
A protest is the objection an importer files against a decision of US Customs and Border Protection, on CBP Form 19 or electronically, within 180 days of the decision for an entry made on or after 18 December 2004. It reaches the classification and rate, the appraised value, the liquidation and all charges or exactions of whatever character. Miss it and the decision is final.
- Protest
- The formal administrative objection to a decision of US Customs and Border Protection under section 514 of the Tariff Act of 1930, filed on CBP Form 19 or electronically within 180 days of the decision. It is the only route to reopen a liquidation an importer believes is wrong.
Every number on a US import entry is provisional until the entry liquidates. After that it is provisional for exactly 180 more days. After that it is not provisional at all. It is final and conclusive on everyone, the United States included. The protest is the thing that lives in those 180 days.
What the regulation actually lets you contest
A protest is not confined to the classification argument it is usually associated with. 19 CFR 174.11 lists the protestable decisions, and the list is wider than most desks use:
All charges or exactions of whatever character, including the accrual of interest, within the jurisdiction of the Secretary of Homeland Security or the Secretary of the Treasury
That paragraph, 174.11(b)(3), is the one worth knowing. It puts a wrongly assessed merchandise processing fee, a harbor maintenance fee charged on a movement the regulation does not reach, and interest accrued on an alleged underpayment all inside the same route as a tariff-classification dispute. The rest of the list covers the appraised value, the classification and the rate, the liquidation or reliquidation itself, a refused drawback claim, and the exclusion of merchandise from entry or delivery, which includes a demand for redelivery after the goods have already gone.
And 174.11(a) covers the boring half that produces most of the money: any “clerical error, mistake of fact, or other inadvertence, whether or not resulting from or contained in an electronic submission, that is adverse to the importer”.
Where the boundary is
A protest reaches CBP’s charges. It does not reach anybody else’s.
The terminal’s storage bill and the carrier’s demurrage are not exactions within the jurisdiction of the Secretary of the Treasury; they are commercial charges under a tariff, and the route against an unreasonable one is a charge complaint to the Federal Maritime Commission, on its own clock and its own evidence. Two wrongly billed numbers on the same shipment can therefore need two different filings, in two different places, with two different deadlines, and only one of them is 180 days.
Who may file, which is more people than do
19 CFR 174.12(a) gives standing to the importer or consignee on the entry papers “or their sureties”, and then, separately, to “any person paying or receiving a refund of any charge or exaction”. A party that paid a charge without being the importer of record has its own right to protest it. A surety demanded against under a customs bond has its own clock, running from “the date of mailing of notice of demand for payment against a bond”.
The mechanics, which are oddly specific
A written protest goes in quadruplicate on CBP Form 19, or on a form of the same size “clearly labeled ‘Protest’ and setting forth the same content in its entirety, in the same order”, with every attachment in quadruplicate too. It may instead be “transmitted electronically pursuant to any electronic data interchange system authorized by CBP for that purpose”, and an electronic submission is not required to be filed four times.
Then the sentence that catches people: under 174.12(f) the date of filing is “the date on which a protest is received by the Customs officer with whom it is required to be filed”. Posting it on day 179 is not filing it on day 179.
Why this belongs on a payment calendar
The 180 days do not begin when somebody notices the error. They begin at the notice of liquidation, which arrives as a routine posting and looks like nothing. A desk that treats liquidation as the moment the file closes, and reconciles the duty, books the landed cost of the consignment and archives the pack, has started a six-month countdown it is not watching, and the only thing that happens at the end is that a recoverable overpayment stops being recoverable.
Which is the argument for deriving the date rather than remembering it. A landed cost tracking system that holds each charge against its own deadline knows the liquidation date because it is on the entry, and day 180 is arithmetic from there. Document packs routinely run about eight days late against free time on the front of a shipment; the back of one has a deadline nobody is chasing at all, because unlike demurrage it sends no invoice while it runs.
Questions traders ask
What is a customs protest?
The formal objection an importer files against a decision of CBP. 19 CFR 174.11 lists the decisions it reaches, "including the legality of all orders and findings entering into those decisions": clerical errors, mistakes of fact and other inadvertences adverse to the importer, and administrative decisions on the appraised value of merchandise, the classification and rate and amount of duties, the liquidation or reliquidation of an entry, a refusal to pay a drawback claim, the exclusion of merchandise from entry or delivery, and "all charges or exactions of whatever character".
How long do I have to file a protest?
180 days for an entry made on or after 18 December 2004, and 90 days for one made before it, under 19 CFR 174.12(e). The clock runs from the date of notice of liquidation or reliquidation, or — where no liquidation is involved — from the date of the decision itself, which 19 CFR 174.12(e)(2) gives as "the date of an exaction; the date of written notice excluding merchandise from entry, delivery or demanding redelivery to CBP custody". The date a protest counts as filed is "the date on which a protest is received by the Customs officer with whom it is required to be filed", not the date you sent it.
Can I protest a fee rather than a duty rate?
Yes, if it is CBP's fee. 19 CFR 174.11(b)(3) makes protestable "all charges or exactions of whatever character, including the accrual of interest, within the jurisdiction of the Secretary of Homeland Security or the Secretary of the Treasury". That wording reaches the merchandise processing fee, the harbor maintenance fee and interest accrued on an underpayment. It does not reach a terminal's storage bill or a carrier's demurrage: those are not CBP exactions, and the route against an unreasonable one is a charge complaint to the Federal Maritime Commission on a different clock.
Who can file a protest?
More people than file one. 19 CFR 174.12(a) allows the importer or consignee shown on the entry papers "or their sureties", "any person paying or receiving a refund of any charge or exaction", any person seeking entry or delivery, any drawback claimant, certain exporters and producers on an origin determination, and any authorised agent of those persons. So a party that paid a charge without being the importer of record has standing in its own right, and a surety that has been demanded against under a bond has its own clock running from "the date of mailing of notice of demand for payment against a bond".
How is a protest filed?
On CBP Form 19, or electronically. 19 CFR 174.12(b) requires a written protest to be filed "in quadruplicate on CBP Form 19 or a form of the same size clearly labeled 'Protest' and setting forth the same content in its entirety, in the same order", with every schedule or attachment also in quadruplicate; a protest "may also be transmitted electronically pursuant to any electronic data interchange system authorized by CBP for that purpose", and electronic submissions "are not required to be filed in quadruplicate". It is filed with CBP "either at the port of entry or electronically".
What happens if I miss the protest window?
The decision becomes final. Under 19 U.S.C. 1514(a) a liquidation is "final and conclusive upon all persons (including the United States and any officer thereof)" unless a protest is filed in time or a civil action contesting a denied protest is commenced in the Court of International Trade. A granted protest produces a reliquidation, which restarts a 180-day clock — but only on what it involved: 19 U.S.C. 1514(d) says a reliquidation "shall not open such entry so that a protest may be filed against the decision of the Customs Service upon any question not involved in such reliquidation".
Does a protest change my landed cost?
It is the only thing that can, once the entry has liquidated. Until liquidation the duty line is an estimate; at liquidation it becomes the figure of record; after liquidation the 180-day protest window is the sole administrative route to move it. A desk that closes the landed cost at liquidation and files the papers has shut the door on its own refund, which is why the protest deadline belongs on the payment calendar next to the liquidation date rather than in a lawyer's diary.
