Subheading 850811 applies only to self-contained electric motor vacuum cleaners with both a power rating of 1,500 W or less AND a dust-bag or other receptacle capacity of 20 liters or less. A unit exceeding either limit falls under 850819, so importers should confirm both specifications with the manufacturer before filing.

Dedicated vacuum cleaner parts that are identifiable as such generally fall under 850870. However, generic components (e.g., electric motors or filters that serve multiple appliance types) may be classified elsewhere under the relevant parts heading. A binding ruling is advisable for high-volume component imports.
