HS Code for Fiberglass mat (mechanically bonded)

Mechanically bonded fiberglass mats are classified under HS code 7019.14. This code is situated within heading 7019, which encompasses glass fibers and articles thereof. The distinction for subheading 7019.14 lies in the physical process used to join the fibers. Unlike chemical bonding, which uses resins or adhesives, mechanical bonding involves physical entanglement. This is typically achieved through needling (where barbed needles punch through the fiber web to interlock them) or stitching (where a separate thread or the glass fibers themselves are used to sew the mat together). These mats are often used in applications requiring high thermal stability or where chemical binders might interfere with the end-use process, such as in certain filtration or high-temperature insulation systems. The classification requires a technical assessment of the mat's construction to confirm the absence of chemical binders as the primary structural agent. If the integrity of the mat is maintained solely or primarily through mechanical means, 7019.14 is the correct designation. This classification is vital for ensuring that industrial-grade insulation and reinforcement materials are taxed and regulated correctly compared to resin-heavy alternatives.

Common Misclassification

Mechanically bonded mats are frequently confused with chemically bonded mats (7019.15). They are also sometimes misclassified under 7019.19 (other glass fiber products) or 5602 (felt), though Chapter 70 is more specific for glass fiber products. Woven fabrics (7019.6x) are also a common point of confusion.

FAQ

What is the HS code for mechanically bonded fiberglass mat?

The HS code for mechanically bonded glass fiber mats is 7019.14.

Can a mat be both mechanically and chemically bonded?

If both methods are used, the mat is classified based on the process that provides its essential character. Usually, needled mats with a small amount of binder remain under 7019.14.
