3920.63.10.00 - Flexible

This HTS category, 3920.63.10.00, specifically covers flexible plates, sheets, film, foil, and strip made from plastics. The material composition for this classification is limited to polycarbonates, alkyd resins, polyallyl esters, or other polyesters. Crucially, these articles must be noncellular and not reinforced, laminated, supported, or similarly combined with other materials. The term "flexible" in this context refers to the material's inherent ability to bend or deform without breaking, a key characteristic for its intended applications.

Within the broader group of "Other plates, sheets, film, foil and strip, of plastics, noncellular and not reinforced, laminated, supported or similarly combined with other materials," and specifically under "Of polycarbonates, alkyd resins, polyallyl esters or other polyesters," this subcategory is distinguished by its focus on unsaturated polyesters. While other polyester types might exist, this code is for those formed from unsaturated polyesters. It is important to note that the sibling category, 3920.63.20.00, is designated for "Other" within this specific polyester grouping, indicating it captures unsaturated polyester products not meeting the specific criteria of 3920.63.10.00, or potentially other polyester variants not explicitly covered.

As this is a leaf node in the HTS, there are no further subcategories. Therefore, the classification hinges on accurately identifying the material as an unsaturated polyester and confirming its physical form as flexible plates, sheets, film, foil, or strip, free from any form of lamination or reinforcement with other materials. Examples of goods that would fall under this classification could include certain types of flexible packaging films or unsupported industrial sheeting made from unsaturated polyesters.
