Source: U.S. Census Bureau, accessed through IHS Markit’s Global Trade Atlas (Harmonized Tariff Schedule of the United States (HTSUS) subheading 8607.30.1000). Imports of freight rail couplers enter under an HTSUS subheading that covers subject and non-subject merchandise. In addition, unfinished merchandise or merchandise that is imported attached to finished rail cars may enter under other HTSUS subheadings. Therefore, publicly available import data may not accurately reflect actual imports of the freight rail couplers covered by the proposed scope of the investigations.
