CBP's Ruling

ItemHTS codeCBP's description of the line
IdealKneeHTS 9506.91.0030Articles and equipment for general physical exercise, gymnastics, athletics, other sports… or outdoor games…; parts and accessories thereof: Other: Articles and equipment for general physical exercise, gymnastics or athletics; parts and accessories thereof... Other

Explanation

CBP found that the IdealKnee is not a mechano-therapy appliance or a massage apparatus, so heading 9019 doesn't apply.

CBP placed the device under heading 9506, which names articles and equipment for general physical exercise, gymnastics and athletics, on the line for articles and equipment for general physical exercise, gymnastics or athletics. The IdealKnee is a tubular steel frame with straps that stretches the leg, foot and knee to improve knee extension and range of motion.

What would change the answer

  • The letter notes that the Explanatory Notes set mechano-therapy apparatus apart from medical exercising equipment designed for home or specialized premises.

Headings CBP ruled out

  • heading 9019, mechano-therapy appliances and massage apparatus: The letter cites the Explanatory Notes to heading 9019: mechano-therapy appliances treat joint or muscle diseases by mechanically reproducing movements, typically under medical supervision. The IdealKnee has no mechanical device and isn't a massage apparatus.

The letter also notes. CBP denied a secondary classification under the Chapter 98 provision for articles specially designed for the blind or other physically or mentally handicapped persons, because that provision excludes articles for acute or transient disability and the IdealKnee is marketed to people recovering from injury or surgery. CBP also found the item is not distinguishable from articles useful to the general public, since it is marketed to athletes, fitness professionals, yoga enthusiasts, dancers and seniors.

Does this apply to your product?

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

  • Is it a device that stretches the leg, foot or knee?
  • Is it a frame with straps, without any mechanical device?
  • Is it marketed as a stretching device for improving range of motion?
  • Is it marketed to the general public, such as athletes and people in rehab?

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