U.S. exports of parts & accessories for semiconductor and flat panel display manufacturing machines (HS 848690) totaled $748.7M in July 2026.
Importers of Parts & Accessories for Semiconductor and Flat Panel Display Manufacturing Machines paid $5.7M in duties in July 2026 — an effective duty rate of 24% on $24.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataReplacement parts, consumable assemblies, and accessories for the full range of equipment covered by heading 8486 — including boule/wafer production, semiconductor device fabrication, flat panel display manufacturing, and assembly/handling machines — are consolidated under 8486900000. Japan and the Netherlands are the leading sources, reflecting the geographic concentration of the world's most advanced semiconductor equipment OEMs in those countries. Supply-chain resilience is a recurring concern for US fabs, as long lead times for precision parts from a small number of specialized manufacturers can constrain tool uptime.

A component classifies as a part under 8486900000 when it is identifiable as being solely or principally used with machines of heading 8486 and has no independent commercial function outside that context. If the component — such as a pump, valve, or optical element — is a general-purpose article with broad applicability, it may be classified under its own specific heading regardless of its end use in a semiconductor tool. Importers should document OEM part numbers and intended use to support the parts classification.
Useful documentation includes OEM purchase orders or invoices referencing the specific tool model, engineering drawings showing the part's fit and function within the machine, and supplier declarations confirming the part is designed exclusively for semiconductor or flat panel display manufacturing equipment. CBP may request this information during examination, particularly for high-value or technically complex components.
