HS Code for Chemically bonded fiberglass fabric

This code applies to glass fiber fabrics where the fibers are held together by a chemical binder rather than a mechanical weave or knit. Under the 2022 HS nomenclature changes, 7019.72 specifically identifies closed chemically bonded fabrics. The classification is based on the material composition (glass fibers) and the structural integrity provided by chemical bonding agents like resins or adhesives. These fabrics are often used in industrial applications for reinforcement or insulation. The "closed" nature of the fabric refers to the density and lack of visible gaps between the fibers, distinguishing it from open-mesh or veil-like structures. Proper classification requires verifying that the primary component is glass fiber and that the bonding method is chemical rather than mechanical (weaving) or thermal (melting).

Products Included

• Chemically bonded fiberglass mats
• Non-woven glass fiber fabrics with resin binders
• Closed-structure fiberglass reinforcement sheets
• Impregnated glass fiber tissues

Common Misclassification

This code is often confused with HS code 7019.61 through 7019.69, which cover woven fabrics of glass fibers. If the fabric has a discernible warp and weft, it is woven and cannot be classified under 7019.72. It is also frequently confused with 7019.71, which is reserved for "veils" (thin, open-structured non-wovens). Additionally, if the glass fibers are simply compressed without a binder, the product might fall under 7019.80 (glass wool).

FAQ

What is the HS code for Chemically bonded fiberglass fabric?

The specific HS code for closed, chemically bonded fiberglass fabrics is 7019.72.

What defines a "closed" fabric in this context?

A closed fabric is one where the fibers are densely packed or bonded such that there are no significant openings or pores, unlike a mesh or a veil.
