This bill establishes a new informal entry process for certain low-value merchandise shipments, known as the Secure Revenue Clearance Channel . It permits **express consignment carriers or operators** to clear goods valued at $600 or less by submitting electronic advanced manifests to U.S. Customs and Border Protection (CBP) for approval. This streamlined procedure aims to expedite customs processing for eligible shipments. However, this informal entry method specifically excludes merchandise subject to **antidumping or countervailing duties**, tariff-rate quotas, or certain taxes and fees collected by other federal agencies. For qualifying shipments, the bill mandates the collection of a new fee, chosen by the importer of record, which can be 20 percent ad valorem, the equivalent formal entry tariff rate, or other applicable duty rates. This fee replaces various existing charges and duties, with all collected amounts remitted quarterly to CBP and deposited into the general fund of the Treasury.
