This bill, known as the U.S. Bicycle Production and Assembly Act, establishes a temporary duty suspension for certain bicycle parts. It amends the Harmonized Tariff Schedule of the United States (HTS) to create a new heading, 9903.87.11, allowing for the duty-free entry of specific parts intended for the assembly or manufacturing of complete bicycles, including electric models and trailers, within the United States. Importers must certify to U.S. Customs and Border Protection (CBP) that these parts will be used for domestic assembly, and they are explicitly excluded from additional duties , such as those under Section 301 of the Trade Act of 1974. This measure aims to significantly reduce costs for domestic bicycle producers and boost U.S. manufacturing. The legislation mandates a report within five years to assess its effectiveness in increasing domestic bicycle assembly, targeting 2 million bicycles annually within five years and 5 million within ten years. The duty suspension and related provisions will be effective for a 10-year period.
