A Binding Ruling is a written decision issued by U.S. Customs and Border Protection on a specific classification, valuation, country of origin, or marking question. Once issued, the ruling binds CBP to the stated treatment for shipments of identical merchandise by the requesting party, until modified or revoked.
Rulings are issued under 19 C.F.R. Part 177. There are two main types:
- NY Rulings — Issued by the National Commodity Specialist Division (NCSD) in New York. These handle most routine classification requests, usually within 30 days.
- HQ Rulings — Issued by CBP Regulations & Rulings at headquarters in Washington, D.C. These handle complex questions, conflicting NY rulings, valuation, and marking issues. They take 60–120 days or longer.
All rulings are published in the Customs Rulings Online Search System (CROSS) within 90 days of issuance. Even rulings issued to other importers are persuasive authority on similar merchandise — making CROSS one of the most valuable research tools for classification work.
Importers who proceed without a binding ruling on a complex classification can face penalties for failing to exercise reasonable care.
