U.S. imports of parts & accessories for measuring, checking, analysing & controlling machines and instruments (nes) (SITC 87490) totaled $15.0M in April 2026, traded with 48 countries.
Importers of Parts & Accessories for Measuring, Checking, Analysing & Controlling Machines and Instruments (NES) paid $1.4M in duties in April 2026 — an effective duty rate of 16% on $8.7M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataActing as the broadest residual parts heading in the SITC measurement and control instrument group, 87490 captures components and accessories for analytical, controlling, and measuring apparatus that are not more specifically provided for elsewhere in the schedule. This includes replacement subassemblies for process analyzers, flow controllers, and industrial automation sensors. The NES designation makes this a frequent landing point for complex multi-function assemblies, and trade professionals should conduct a thorough classification analysis to confirm no more specific parts heading applies before filing entry under 87490.

Because 87490 is a catch-all, CBP may challenge entries where a more specific parts heading exists, potentially resulting in reclassification, duty underpayment, and liquidation adjustments. A thorough review of the parent instrument's classification and the part's dedicated use is the standard practice before claiming the NES heading.
Embedded software that is integral to the hardware module and has no separate commercial value is generally treated as part of the hardware for classification purposes. However, separately invoiced software licenses or downloadable firmware updates are typically classified as software under a different SITC heading. The physical medium and invoicing structure both influence the correct classification.
