Articles that meet the definition of a medical device under the Federal Food, Drug, and Cosmetic Act — such as examination tables with integrated diagnostic functions or powered surgical positioning systems — require FDA registration and may need 510(k) clearance before importation. Standard barber chairs and non-functional furniture components generally do not. Consult FDA's device database and a licensed customs broker to determine the applicable regime for a specific product.

Heading 9402 captures chairs that combine rotating, reclining, and elevating movements and are designed for professional grooming or clinical use. A general office or home swivel chair with only height adjustment falls under heading 9401 (specifically the swivel-seat subheadings). The combination of all three mechanical movements — rotation, recline, and elevation — in a professional-use context is the key classifier.
