CBP published several thousand prospective rulings in 2020 on its Customs Rulings Online Search System (CROSS) database. The agency issues its rulings from either the National Commodity Specialist Division in New York, which handles issues like classification, country of origin, marking and preferential treatment, or the Office of Regulations and Rulings at CBP headquarters in Washington, D.C., which may also decide other issues, such as valuation, drawback, exclusion order enforcement and liquidation.

CBP published notices in the Customs Bulletin revoking or modifying numerous rulings in 2020.
