U.S. Customs and Border Protection requires importers to exercise Reasonable Care when classifying goods. Harmonizer doesn't just generate HTS codes—it builds the legal evidence trail to prove it.
CBP Warning: Importers who cannot demonstrate Reasonable Care face penalties up to 4x the unpaid duties, plus potential seizure of goods.
Under 19 U.S.C. § 1484, the importer of record is legally responsible for the accuracy of their entry documents—including HTS codes. CBP does not accept ignorance or error as a defense.
"Reasonable Care" means you must be able to demonstrate that you took active, documented steps to determine the correct classification. Your process is on trial—not just the final code.
Legal Citation
19 U.S.C. § 1592 — Civil penalties for filing inaccurate entry documents due to negligence or fraud.
The "Informed Compliance" Doctrine
CBP publishes guidance on Reasonable Care expectations—but few importers have the time or expertise to apply it correctly at scale.
Broker Responsibility
Licensed customs brokers who provide classification advice share liability exposure if they cannot document their reasoning.
Without Reasonable Care
Negligence Penalty
Up to 2x unpaid duties for first-time negligence findings under § 1592.
Gross Negligence
Up to 4x unpaid duties if CBP determines the importer was recklessly indifferent.
Cargo Seizure
CBP may seize goods pending investigation—halting your supply chain entirely.
License Revocation
Repeated violations can lead to suspension or revocation of a broker's CBP license.
Every classification produced by Harmonizer is engineered to satisfy the CBP's Reasonable Care standard—automatically, at scale.
