The shim is constructed of non-cellular Derlin acetal homopolymer plastic. It is coated on one side with an acrylic adhesive and release paper. The shim is rectangular with one convex curved end. The shim measures 12mm long by 7.5mm wide. The applicable subheading for the shim will be 3919.90.5060, Harmonized Tariff Schedule of the United States (HTSUS) which provides for Self-adhesive plates, sheets, film, foil, tape, strip and other flat shapes, of plastics, whether or not in rolls: Other: Other: Other. The general rate of duty will be 5.8 percent ad valorem.

This includes, but is not limited to, tariffs and other duties as provided for in Subchapter III to Chapter 99, HTSUS. Thus, for example, in addition to the classification stated above, the merchandise covered by this ruling may also need to be reported with either the Chapter 99 provision under which an additional tariff applies or one of the Chapter 99 provisions covering exceptions to such tariffs.
