3921.90.11.00 - Over 70 percent by weight of plastics

This HTS category, 3921.90.11.00, encompasses other plates, sheets, film, foil, and strip made of plastics. Specifically, it applies to those products where plastics constitute over 70 percent of their weight. This classification is for composite materials that include textile components. The key distinguishing feature of this subcategory is that the textile components, when present, must be composed predominantly of man-made fibers by weight, meaning the weight of man-made fibers must be greater than the weight of any single other type of textile fiber used.

The sibling category, 3921.90.15.00, covers "Other" products within the same broad classification. This implies that 3921.90.15.00 would include composite sheets, films, etc., that do not meet the specific criteria of the current category, such as those where man-made fibers do not predominate by weight, or where the textile component is made entirely of natural fibers, or where the weight per square meter is outside the specified range.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, the focus for classification within 3921.90.11.00 is on the precise determination of the plastic content (over 70% by weight) and the composition of the textile component, ensuring man-made fibers outweigh any other single type of fiber. Examples might include certain reinforced plastic films or sheets used in industrial applications where the plastic provides the primary barrier properties and the man-made fiber textile offers structural support or specific surface characteristics.
