3920.92.00.00 - Of polyamides

This HTS category, 3920.92.00.00, specifically covers plates, sheets, film, foil, and strip that are made of polyamides. These are noncellular, meaning they do not contain voids, and they are not reinforced, laminated, supported, or otherwise combined with other materials. Polyamides, commonly known as nylons, are a class of polymers characterized by the presence of amide linkages in their molecular structure. Examples of products falling under this classification include unreinforced nylon films used for packaging, nylon sheets for industrial applications, or nylon foil.

This classification distinguishes itself from its siblings by its specific material composition. For instance, sibling category 3920.91.00.00 covers materials made of poly(vinyl butyral), while 3920.93.00.00 pertains to amino-resins and 3920.94.00.00 to phenolic resins. Therefore, the key distinguishing factor for 3920.92.00.00 is the presence of polyamide as the sole polymeric component in the noncellular, uncombined plastic article. The broader category of "Of other plastics" (3920.99) would encompass materials not specifically listed under the preceding subheadings, further emphasizing the distinct nature of polyamide-based products.

As this node is a leaf node, there are no further subdivisions. The classification criteria are based on the material (polyamide) and the physical form (plates, sheets, film, foil, strip) of unreinforced, uncombined plastics. Careful consideration should be given to ensure the material is indeed a polyamide and that the product does not meet the criteria for reinforcement, lamination, or support with other materials, which would necessitate classification under a different subheading.
