Heading 7019

Glass fibers (including glass wool) and articles thereof (for example, yarn, rovings, woven fabrics)

87 declarable lines

Heading 7019 covers glass fibers and glass wool, plus articles made from them such as rovings, yarns, chopped strands, mats, woven fabrics and insulation. The heading splits first by product form: strand and yarn products, mats, mechanically bonded (woven) fabrics, chemically bonded fabrics, and glass wool articles. Woven fabric lines then split by whether the fabric is closed or open, by width over or under 30 cm, by colored or not colored, and by whether it is resin-impregnated tire cord fabric.
