3920.62.00.90 - Other

This HTS classification covers "Other" plates, sheets, film, foil, and strip made of poly(ethylene terephthalate) (PET) that are noncellular and are not reinforced, laminated, supported, or otherwise combined with other materials. This means the material consists purely of PET and does not incorporate other substances or structures to enhance its properties or form composite goods. Examples within this category might include plain PET films used for various packaging or industrial applications, provided they meet the noncellular and unsupported criteria.

Distinguishing this category from its sibling, "Metallized PET film," is crucial. While both are derived from poly(ethylene terephthalate) in sheet form, this classification specifically excludes any PET film that has undergone a metallization process. Metallization involves applying a thin layer of metal to the surface of the film, which fundamentally alters its properties and purpose, thus placing it in a separate, more specific HTS subheading.

As this is a leaf node, there are no further subcategories under this specific HTS code. Therefore, the classification relies on meticulously adhering to the defined material (PET), form (plates, sheets, film, foil, strip), and structural characteristics (noncellular, not reinforced, laminated, supported, or similarly combined). Proper identification of the base material as exclusively poly(ethylene terephthalate) and confirmation that no additional materials or treatments have been applied are the key criteria for classifying goods under this subheading.
