Importers of Parts (NES) for Civil Engineering, Mining & Public Works Machinery paid $98.8M in duties in April 2026 — an effective duty rate of 31% on $316.4M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataResidual parts not elsewhere specified for civil engineering, mining, and public-works machinery — including components covered under SITC heading 723 and crane-type equipment under heading 744.3 — are consolidated here. The breadth of this heading makes it a common landing point for multi-function or hybrid components that serve several machine types, and its NES character means it should only be used after ruling out more specific parts headings. Trade professionals dealing in aftermarket or MRO supply chains for heavy construction equipment frequently encounter this code when sourcing non-OEM components with broad compatibility.

This heading is residual — it applies only when no more specific SITC parts heading covers the component. Importers should first check dedicated parts headings for earthmoving, boring, and lifting equipment. Only after confirming the part is not described elsewhere should this NES code be used, and the classification rationale should be documented.
Yes — parts for cranes and similar lifting equipment that are not elsewhere specified may also fall under this heading rather than a dedicated crane-parts provision, depending on the SITC schedule structure. Importers should cross-reference both the civil-engineering machinery section and the lifting-equipment section to identify the most specific applicable heading before defaulting to this residual code.
