HS Code for Fiberglass cloth (rovings)

HS code 7019.61 is designated for fiberglass fabrics made specifically from rovings. Rovings are continuous strands of glass filaments gathered into a single bundle without a significant twist. Under Chapter 70, which covers glass and glassware, heading 7019 is dedicated to glass fibers and articles thereof. The subheading 7019.61 specifically addresses mechanically bonded fabrics and closed woven fabrics of rovings. This classification is technically precise, focusing on the weave structure and the type of glass fiber used. These fabrics are often used in industrial applications for reinforcement in composite materials, such as boat hulls, automotive parts, and aerospace components. The classification follows GRI 1, as the heading text explicitly mentions glass fibers, and GRI 6, which differentiates between the types of woven fabrics (rovings vs. yarns). The term closed woven refers to the density of the weave, ensuring the fabric provides a solid surface rather than an open mesh or grid. This material is valued for its high tensile strength and resistance to heat and chemicals.

Products Included

• Woven roving fiberglass cloth
• Heavy-duty fiberglass reinforcement fabric
• Mechanically bonded glass fiber fabrics
• Closed-weave roving mats for laminating
• Biaxial or triaxial roving fabrics

Common Misclassification

Fiberglass cloth of rovings is often confused with fabrics made from glass yarns, which fall under 7019.62 (other closed woven) or 7019.63 (plain weave). The distinction lies in the fiber structure; rovings are untwisted bundles, whereas yarns are twisted. Furthermore, non-woven products like glass wool or chopped strand mats are classified under 7019.11 through 7019.19. Importers often mistake thin fiberglass veils for woven cloth, but veils are typically non-woven and belong in 7019.71. It is critical to verify the technical data sheet to confirm if the input material is roving or yarn.

FAQ

What is the HS code for fiberglass cloth rovings?

The HS code for mechanically bonded or closed woven fabrics of glass fiber rovings is 7019.61.

What is the difference between rovings and yarns in HS classification?

Rovings are bundles of continuous filaments without twist, while yarns are twisted glass fibers. This distinction determines whether the fabric falls under 7019.61 (rovings) or 7019.62/63 (yarns).
