Last updated: April 2026 dataThe not-elsewhere-specified (NES) residual category for air and vacuum pumps captures specialized or hybrid designs that do not fit neatly into the more specific headings for vacuum pumps, hand-operated pumps, refrigeration compressors, or towable compressors. Products landing here often include laboratory peristaltic pumps used for air, pneumatic transfer pumps, and certain regenerative blowers. Because this is a catch-all heading, classification disputes are relatively common, and importers with novel pump designs should consider seeking a binding ruling to avoid reclassification at audit.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
This residual heading captures air and vacuum pumps that do not meet the specific criteria of the named subheadings — for example, regenerative blowers, side-channel blowers, pneumatic diaphragm pumps for air service, and certain specialty laboratory pumps. If a product could plausibly fit a more specific heading, that heading generally takes precedence.
When a pump's design or function overlaps with multiple headings, the general rules of classification require selecting the most specific description. Importers should document the pump's operating principle, intended application, and technical specifications, and may wish to request a binding ruling from CBP before the first shipment to lock in the correct classification.
