7019.71.00.00 - Veils (thin sheets)

HTS Code 7019.71.00.00 specifically classifies veils, which are defined as very thin sheets of glass fibers. These products are characterized by their extreme thinness and are typically manufactured using processes that result in a delicate, membrane-like structure. While falling under the broader category of glass fiber fabrics, these veils are distinct due to their specific form factor and intended application, often related to filtration, separation, or as reinforcement materials where a minimal thickness is paramount.

This classification is differentiated from its siblings by its focus on "veils" as opposed to other forms of glass fiber fabrics. Sibling category 7019.72 covers "other closed fabrics," implying materials with a more substantial weave or structure that encloses a volume, and 7019.73 encompasses "other open fabrics," which typically refer to materials with distinct interstices or larger mesh openings. Therefore, 7019.71.00.00 is reserved for products that are distinctly sheet-like and exceptionally thin, distinguishing them from more conventional woven or non-woven glass fiber fabrics.

As a leaf node within the HTS structure, this category does not have further subcategories. Classification under 7019.71.00.00 hinges on identifying materials that are demonstrably thin sheets composed of glass fibers, distinguishing them from thicker or more structured glass fiber fabric constructions. The defining characteristic is the very fine, veil-like nature of the material.
