CBP Rulings

Informed compliance is CBP's principle that effective customs enforcement is best achieved through importer education — and its commitment to providing guidance through Informed Compliance Publications, training, and outreach.

A CBP binding ruling applies prospectively — binding CBP at all ports for the requesting party's future imports of the described goods. Courts review classification de novo and are not bound by CBP rulings.

Reasonable care is the legal standard importers must meet when making classification decisions under 19 USC 1484 — the threshold for avoiding CBP penalty liability and the foundation of defensible trade compliance.

An importer may cite a CBP ruling issued to another party as persuasive authority — but cannot claim its binding prospective effect. Differences in product specifications, materials, or end use can make an apparently identical ruling inapplicable.

An importer may request a binding classification ruling from CBP before importation by submitting a detailed ruling request to the National Commodity Specialist Division — obtaining advance certainty and a reasonable care defense.

CBP may revoke or modify a binding ruling, but must publish notice in the Customs Bulletin and allow at least 30 days for public comment before the revocation takes effect — with prospective application only.
