This document adopts as a final rule, without change, the proposed amendments to the U.S. Customs and Border Protection (CBP) regulations to permit an applicant to file the documentation required for duty-free treatment of certain visual and auditory materials of an educational, scientific, or cultural character under subheading 9817.00.40, Harmonized Tariff Schedule of the United States (HTSUS), at any time prior to the liquidation of the entry. This change allots more time for the importer to provide the necessary certification documentation to CBP and serves to align the filing of required certification documentation with a change in CBP policy that extended the liquidation cycle for entries in the ordinary course of business from 90 days to 314 days after the date of entry.
