7019.14.00.00 - Mechanically bonded mats

HTS Code 7019.14.00.00 specifically covers mechanically bonded mats of glass fibers. These mats are characterized by their construction where glass fibers are physically entangled or interlocked, rather than being held together by a chemical binder or adhesive. Examples include mats formed by carding, needle-punching, or other mechanical processes that create a cohesive structure from the glass filaments.

This category is distinguished from its siblings primarily by the method of bonding. Unlike chemically bonded mats (7019.15.00.00), which rely on resins or other chemical agents to hold the fibers together, mechanically bonded mats achieve their integrity through physical interlocking. Furthermore, it differs from categories covering chopped strands (7019.11.00.00) and rovings (7019.12.00) by its mat form, which implies a planar, non-directional or randomly oriented arrangement of fibers, as opposed to discrete strands or continuous rovings.

As this is a leaf node within the HTS, there are no further subdivisions. Therefore, classification under 7019.14.00.00 is determined by the product being a mat composed of glass fibers and the method of bonding being mechanical. The specific dimensions or density of the mat are not primary classification criteria at this level, as long as it fits the general description of a mechanically bonded glass fiber mat.
