7019.15.00.00 - Chemically bonded mats

This HTS category, 7019.15.00.00, specifically covers chemically bonded mats made from glass fibers. These mats are formed by a process where glass fibers are held together using chemical bonding agents or resins, creating a cohesive structure. Examples include glass wool insulation products where binders are used to maintain the shape and integrity of the loose fibers, or reinforcement mats used in composite materials that rely on chemical adhesion.

It is important to distinguish these chemically bonded mats from other glass fiber mats. Notably, sibling category 7019.14.00.00 covers "mechanically bonded mats," which achieve their cohesion through physical interlocking of fibers rather than chemical agents. Similarly, categories for chopped strands (7019.11.00.00), rovings (7019.12.00), and other yarn and slivers (7019.13 and 7019.19) encompass different forms of glass fiber preparations, each with distinct physical characteristics and manufacturing processes.

As a leaf node, this classification does not have further subcategories. Therefore, the classification of goods under 7019.15.00.00 hinges on the definitive presence of glass fibers and the application of chemical bonding agents to create a mat structure. The key determining factor for inclusion in this category is the method of bonding, differentiating it from mechanically bonded or other unbonded forms of glass fiber materials.
