The defining criterion is the power source: goods here are entirely human-powered (hand-cranked, lever-operated, or manually pressed). Electrically driven kitchen appliances — even small ones — classify under the electrical machinery chapter rather than here, regardless of weight.

No — base metal parts of hand-operated mechanical food-preparation appliances are explicitly included within this heading, so replacement grinding burrs, blades, or frames of base metal remain here rather than being classified as general hardware or cutlery parts.
