What is the HTS code for a plastic walker wheel nut cover?

HTS code

3926.90.9989

CBP classified a plastic walker wheel nut cover under HTS 3926.90.9989 in ruling N358851. That line covers other articles of plastics. CBP found the cover isn't an accessory of the walker, so it stays with the plastic heading rather than the orthopedic appliance heading.

The Product

  • Injection molded polypropylene plastic cover that fits over the wheel nut of a standard folding aluminum walker.
  • Five connecting legs and a wheel nut cap; teeth on each leg engage the wheel's spokes and lock the cover on.
  • Covers the nut's sharp edges to prevent damage to walls, wall corners, cabinets and furniture, and protects the nut itself.

CBP's Ruling

ItemHTS codeCBP's description of the line
Walker wheel nut coverHTS 3926.90.9989Other articles of plastics and articles of other materials of headings 3901 to 3914: Other: Other: Other

Explanation

CBP found the cover isn't an accessory of the walker, which ruled out the orthopedic appliance heading and its line for parts and accessories.

That left the cover as an article of plastic that no other heading covers more specifically, so it falls under heading 3926, other articles of plastics. Within that heading, CBP placed it on the line for other articles.

Headings CBP ruled out

  • Heading 9021, orthopedic appliances, including parts and accessories: The walker's primary function is support and stability for ambulation; a cover that shields the nut and nearby walls and furniture doesn't directly contribute to the walker's effectiveness, so it isn't an accessory.
  • Articles for the blind or handicapped (heading 9817): The cover is neither a part nor an accessory of the walker, so it doesn't meet the wording of that provision.

Does this apply to your product?

It likely does if you can answer yes to each of these:

  • Is it made of plastic?
  • Does it clip onto a walker wheel to cover the exposed wheel nut?
  • Is its purpose to protect the nut and nearby walls or furniture from damage?
  • Does it do nothing to improve the support and stability the walker provides?

A no to any of them can mean a different code. A licensed broker can classify your product.
