U.S. imports of Centrifuges (Excluding Clothes-Dryers), NESOI (HS 842119) totaled $21.8M in August 2026, imported from 41 countries.
Importers of Centrifuges (Excluding Clothes-Dryers), NESOI paid $2.4M in duties in August 2026, an average duty rate of 11.09% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataIndustrial, laboratory, and process centrifuges not elsewhere specified — covering applications from pharmaceutical and biotech processing to chemical separation and food production — all enter under the single US line 8421190000. Germany leads US imports of these machines, reflecting that country's strength in precision separation technology for life sciences and chemical industries, with Canada, China, Sweden, and Mexico also supplying the market. The breadth of this NESOI heading means classification disputes often arise at the boundary with cream separators (842111) and with filtering/purifying apparatus (842121), making a clear description of the machine's operating principle and designed application essential in entry documentation.

Both solid-liquid and liquid-liquid separation centrifuges for pharmaceutical use classify under 8421190000, as the heading covers centrifuges NESOI regardless of the phase separation involved. What matters is that the machine operates by centrifugal force and is not a cream separator (842111) or a clothes-dryer (842112). Documentation of the machine's operating principle and intended pharmaceutical application supports correct classification and may be relevant to any end-use certificate requirements.
Centrifuges separate components by applying centrifugal force — the machine spins to create density-driven separation. Filtering and purifying apparatus (heading 8421, subheadings 842121 onward) use a physical barrier or medium to remove particles or impurities. A machine that primarily uses a filter medium classifies as filtering apparatus even if it incorporates some rotational motion; one that relies principally on centrifugal force classifies as a centrifuge. Technical specifications and the manufacturer's description of the separation mechanism are key evidence.
