What is the HTS code for a plastic light pipe?

HTS code

3926.90.9989

CBP classified a clear polycarbonate light pipe, a headset part that sits over an LED so its light shows on the outside of the device, under HTS 3926.90.9989 in ruling N356496. CBP found it an article of plastic not covered more specifically elsewhere, so it takes the line for other articles of plastics.

Explanation

The light pipe is wholly clear polycarbonate plastic and has no electrical components. CBP found it would be considered an article of plastic, and that nothing covers it more specifically elsewhere. Heading 3926 covers other articles of plastics, and CBP placed the part on that heading's line for other articles.

Does this apply to your product?

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

  • Is it made wholly of plastic?
  • Is it free of electrical components?
  • Is it a light pipe that sits over an LED so its light shows on the device's outside?

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