SITCSection 7
U.S. imports of railway and tramway track fixtures, fittings, and signaling equipment (SITC 79191) totaled $3.8M in April 2026, traded with 30 countries.
Importers of Railway and Tramway Track Fixtures, Fittings, and Signaling Equipment paid $587K in duties in April 2026 — an effective duty rate of 17% on $3.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataFixed infrastructure components — including switches, crossings, signal gantries, interlocking systems, and electronic traffic-control equipment — that keep rail and tramway networks operating safely are classified here along with their parts. Mechanical and electronic signaling systems are explicitly included, making this heading relevant to both civil infrastructure contractors and advanced rail-technology suppliers. Given the safety-critical nature of signaling and traffic-control equipment, importers should be aware that certain products may be subject to Federal Railroad Administration (FRA) or Federal Transit Administration (FTA) technical standards in addition to standard customs requirements.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Safety-critical signaling and traffic-control systems for US rail networks may need to comply with FRA regulations for freight and intercity rail, or FTA standards for transit applications, before they can be placed in service. Customs clearance and regulatory approval are separate processes; importers should engage with the relevant agency early in the procurement cycle to avoid delays.
Parts specifically designed for railway track fixtures, fittings, or signaling equipment are explicitly included in this heading, so dedicated replacement components (e.g., switch blades, point motors, signal relay housings) generally classify here rather than under generic mechanical parts headings. Parts that are clearly general-purpose mechanical components may fall elsewhere; a binding ruling from CBP is advisable for ambiguous items imported in significant volume.
