U.S. imports of numerically controlled drilling machines for removing metal (nesoi) (HS 845921) totaled $2.0M in July 2026, traded with 12 countries.
Importers of Numerically Controlled Drilling Machines for Removing Metal (NESOI) paid $257K in duties in July 2026 — an effective duty rate of 16% on $1.6M in dutiable value, based on actual customs collections rather than the published tariff schedule. Numerically Controlled Drilling Machines for Removing Metal (NESOI) imports of $2.0M in July 2026 ran 55% below the year-to-date monthly average of $4.4M.
Last updated: July 2026 dataNumerically controlled drilling machines for metalworking — covering radial, multi-spindle, and other N/C drill configurations not elsewhere specified — are widely used in precision component manufacturing for aerospace, automotive, and energy applications. Germany leads US import supply under this heading, followed by Canada and the Netherlands, with Turkey and Italy also present — a supplier mix that spans both high-precision European OEMs and North American sources. The US schedule splits these machines into used/rebuilt (8459210040) and new (8459210080) units, making condition documentation a straightforward but important classification step. Importers should distinguish N/C drilling machines from machining centers with drilling capability, as the latter are classified under heading 8457 when automatic tool changing is the primary design feature.

The distinction turns on design intent and primary function. A machining center is characterized by its automatic tool-changing system and ability to perform multiple different operations (milling, drilling, boring) in a single setup. A machine designed principally for drilling — even with CNC control — that lacks an ATC and is not capable of milling operations is properly classified as a drilling machine under 8459.21. When a machine straddles both descriptions, the principal function at the time of importation governs, and a CBP binding ruling can provide certainty.
CBP generally expects the commercial invoice to state the machine's condition explicitly, along with the year of manufacture and any refurbishment details. Supporting documents such as a prior owner's maintenance log, a refurbisher's certification, or a surveyor's condition report strengthen the declaration. Importers should also ensure the customs value reflects the actual transaction value for a used machine, as CBP may compare declared values against market benchmarks for known models.
