U.S. imports of parts of railway & tramway locomotives (nesoi) (HS 860791) totaled $11.0M in July 2026, traded with 32 countries.
Importers of Parts of Railway & Tramway Locomotives (NESOI) paid $3.0M in duties in July 2026 — an effective duty rate of 28% on $10.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataLocomotive-specific components not covered by the more narrowly defined brake, coupling, or axle subheadings — such as engine housings, traction motor frames, control electronics housings, and structural castings — are captured under heading 860791, with a single 10-digit line (8607910000) covering all such parts. Mexico and Canada together dominate US supply, reflecting deep North American rail manufacturing integration, while China and India serve as significant alternative sources. Locomotive parts are high-value, low-volume shipments where precise technical documentation and correct classification relative to adjacent headings (e.g., electrical components under Chapter 85) are recurring compliance challenges.

The key is GRI 1 and the relevant Section XVI note: parts that are identifiable as suitable for use solely or principally with railway locomotives generally classify under heading 8607 rather than a general electrical or mechanical heading. However, multipurpose electrical components (e.g., generic circuit breakers) may remain in Chapter 85. When the principal-use test is ambiguous, a binding ruling request to CBP provides the most reliable answer.
Beyond standard entry documentation, importers claiming USMCA preferential treatment must have a valid certification of origin and ensure the parts meet the applicable tariff-shift or regional-value-content rules under the agreement. For high-value locomotive components, a detailed bill of materials and manufacturer's affidavit supporting origin are advisable to withstand CBP verification.
