Which code does this activity belong in?

Code 81121 covers establishments that repair and maintain consumer electronics, computers, office machines, communication equipment, and precision instruments such as microscopes, medical devices, and scientific equipment, without selling these items as new products. This code is distinct from automotive repair services classified in 8111, which focus on vehicles and their systems. Code 81121 also differs from household appliance and equipment repair in 8114, which covers home and garden equipment; the boundary lies in the electronic and precision nature of the equipment rather than its consumer or domestic purpose.
