A CBP protest under 19 USC 1514 can recover overpaid duties, but the 180-day deadline is unforgiving. When to file and how to build one that wins.
A CBP protest, filed under 19 USC 1514, is the formal mechanism to challenge CBP decisions on your entries: the classification, the valuation, the duty rate applied, or a charge like liquidated damages. It is not a negotiation and not a complaint. It is a legal filing that says CBP got the decision wrong and here is why, with evidence.
The distinction matters because protests have teeth. A granted protest results in reliquidation: CBP reprocesses the entry with the corrected decision and refunds the difference with interest. A denied protest preserves your right to take the case to the Court of International Trade. The protest is the gateway to every remedy beyond it, which is why the filing deadline is unforgiving.
File when the dollars justify the effort and the law supports your position. The classic case is classification: CBP liquidated your product under a higher-duty heading, but the product's condition, the tariff language, and the explanatory notes support the lower-duty heading. If the duty difference across your entries is material, a protest is the correct tool.
Valuation disputes are the second common case: CBP rejected your declared value or your first-sale claim, and you have the documentation to support it. Liquidated damages and penalty mitigation decisions can also be protested. The common thread is a specific CBP decision, a defensible alternative, and enough money at stake to warrant the legal cost. Protests over a few hundred dollars rarely make sense; protests over systematic misclassification across a year of entries often do.
Protests must be filed within 180 days of liquidation, the date CBP finalizes the entry. Miss it and the decision stands, no matter how wrong it was. This is the single most expensive mistake importers make: discovering a systematic classification error in month eight, when the first six months of entries are already beyond protest.
The fix is a liquidation calendar. Track every entry's liquidation date, and review liquidated entries for protestable issues well before the deadline. Many brands assign this to their broker with explicit instructions, but the importer owns the deadline regardless of who files. Calendar it, review it quarterly, and never assume the broker is watching.
Winning protests are built on evidence, not argument. Assemble the product's physical specifications, photographs of the imported condition, the relevant tariff provisions with explanatory notes, any binding rulings on similar products, and expert analysis if the classification turns on technical facts. The protest should read like a brief: the decision, why it was wrong, and what the correct decision is, each supported by exhibits.
Be selective. A protest with three strong claims beats a protest with ten weak ones. CBP protest reviewers see volume filers and give the most attention to the filings that are clearly right. And consider the relationship dimension: a well-documented protest on a genuine disagreement is normal business, but protesting every entry poisons the working relationship with the port. File the ones you would take to court, because the protest is the first step there.
The formal challenge to a CBP decision on your entry, covering classification, valuation, duty rates, and charges like liquidated damages. A granted protest leads to reliquidation and a refund with interest. A denied protest preserves your right to litigate in the Court of International Trade. It is the required first step for most duty-recovery claims.
180 days from the liquidation date of the entry. There are no extensions and no excuses; a late protest is invalid regardless of merit. Track liquidation dates for every entry and review them for protestable issues quarterly, well before the window closes on any entry.
When a specific CBP decision cost you real money and the law supports your position. Systematic misclassification across many entries is the classic case. One-off small-dollar disagreements usually are not worth the legal cost. The test: would you take this to court if the protest is denied? If yes, file.
Evidence: product specs, photos of the imported condition, the tariff provisions and explanatory notes supporting your classification, binding rulings on similar products, and expert analysis for technical questions. Structure it like a brief with exhibits. Three strong claims beat ten weak ones, and reviewers reward filings that are clearly correct.
