What is the HTS code for plastic drainage mesh used behind wall cladding?

HTS code

3926.90.9989

CBP classified a polyethylene plastic drainage mesh sold by the roll under HTS 3926.90.9989 in ruling N345344. CBP found the mesh is an article of plastic that no other heading covers more specifically, so it falls on the line for other articles of plastics.

Polyethylene plastic meshHTS 3926.90.9989Other articles of plastics and articles of other materials of headings 3901 to 3914: Other: Other: Other

Explanation

CBP found the polyethylene mesh is an article of plastic and that no other heading covers it more specifically. That put it under heading 3926, other articles of plastics, on the residual line for other articles.

Does this apply to your product?

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

  • Is it a mesh or netting made wholly of polyethylene plastic?
  • Is it made by an extrusion process?
  • Is it used in construction to create a drainage air space between an inner wall and exterior cladding?

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