CBP Protest
A CBP protest is a formal administrative challenge to a CBP classification or duty assessment decision, filed on CBP Form 19 within 180 days of the liquidation of the customs entry. It is the primary administrative remedy for importers who disagree with a CBP classification. If the protest is denied, the importer may appeal to the U.S. Court of International Trade.
In Detail
A protest is filed after CBP has taken final action — after a CF-29 action has been finalized and the entry has been liquidated with the adverse classification. The 180-day filing deadline runs from the date the importer receives notice of liquidation, not from the date of the CF-29. Missing the deadline typically forfeits the administrative remedy entirely — the liquidated classification becomes final and the only remaining avenue is judicial review, which requires exhaustion of the protest process as a prerequisite.
The protest must identify the specific entry and the specific grounds for the challenge. For classification protests, the grounds are that CBP applied an incorrect HTS code. The protest should include a complete legal argument: the correct classification, the GRI rule that supports it, the heading text and note analysis, applicable CROSS rulings, WCO Explanatory Notes, expert analysis if relevant, and any other authority supporting the importer's position. The quality of this submission determines the outcome of the protest review.
If CBP denies the protest, two further avenues exist. First, the importer can apply for Further Review if the matter presents a novel question of law or policy — this elevates the protest to CBP's Office of Trade for a more deliberate review, and a favorable Further Review determination is applied prospectively to future entries. Second, if Further Review is denied or inapplicable, the importer can appeal to the U.S. Court of International Trade within 180 days of protest denial. CIT appeals are de novo — the court reviews the classification on the merits, not just whether CBP's decision was reasonable — and published CIT opinions become binding HTS classification precedent for all importers.
Classification Significance
The protest is the formal endpoint of the CBP administrative process for classification disputes. The strength of the protest record depends heavily on the quality of the classification documentation throughout the pre-protest process — from the original entry through the CF-28 response and the CF-29 defense. A well-documented original classification that CBP overrode without sound legal basis is the foundation of a strong protest. A classification based on an undocumented tariff lookup is nearly impossible to defend in protest.
How Kanon Handles This
Kanon's Classification Support Package, as an immutable record of the classification methodology at the time of import, is the documentary foundation for a protest. The package demonstrates that the importer followed a legally defensible GRI-based methodology — the core argument in any classification protest — and provides the evidence needed to support each legal argument in the protest submission.
