7019.64 - Closed woven fabrics, plain weave, of yarns, coated or laminated:

This HTS category, 7019.64, encompasses closed woven fabrics specifically constructed from yarns that have undergone a coating or lamination process. These fabrics maintain a plain weave structure, meaning each warp yarn interlaces with each weft yarn in a simple alternating pattern. The crucial distinguishing factor here is the presence of a coating or laminate applied to the yarns, which alters the fabric's properties, such as improving its strength, durability, water resistance, or electrical insulation.

To differentiate 7019.64 from its siblings, consider the materials and treatments. It is distinct from 7019.63, which covers similar plain weave closed fabrics but explicitly excludes those where the yarns are coated or laminated. Conversely, this category focuses on fabrics where the yarns themselves are treated prior to weaving, or the woven fabric undergoes a lamination process, setting it apart from categories dealing with rovings or open woven structures.

The subcategories within 7019.64 provide further refinement based on the fabric's dimensions. The first subcategory, "Of a width not exceeding 30 cm," will classify fabrics meeting this specific width requirement. The subsequent subcategory, "Other," will encompass all remaining fabrics within 7019.64 that do not fall into the narrower width classification. This allows for more precise tariff application based on the physical characteristics of the coated or laminated woven glass fiber fabric.
