Pumps fitted with — or designed to accept — a measuring device, but not classifiable as filling-station fuel or lubricant dispensers, fall into this residual N.E.S. category. Typical applications include chemical dosing, beverage dispensing, and process-industry metering where precise volume delivery is required. The N.E.S. designation makes correct classification dependent on ruling out the more specific metered-pump headings, and importers dealing in multi-purpose metering pump lines should document the intended end-use to support their classification position.
