HS Code for Fiberglass mats

Fiberglass mats and threads are classified under HS code 7019.19. This subheading covers glass fiber products in the form of threads and mats that are not mechanically or chemically bonded in the specific ways described in other subheadings. A common product in this category is the chopped strand mat (CSM), which consists of glass fibers cut to specific lengths and distributed randomly across a plane. While these mats may use a binder to hold the fibers together, they are distinguished from the "mechanically bonded" fabrics of 7019.62. The classification also includes glass fiber threads that are not yet processed into yarns or rovings. These materials are fundamental in the production of fiber-reinforced plastics (FRP), where they provide multi-directional reinforcement. The classification depends heavily on the physical form of the glass fiber and the absence of the specific bonding or weaving characteristics that would trigger a more specific subheading. It is a broad category for non-woven glass fiber structures used primarily in industrial molding and lamination.

Products Included

• Chopped strand mats (CSM)
• Fiberglass surfacing veils
• Glass fiber threads
• Non-woven tissue mats
• Continuous filament mats (non-mechanical)

Common Misclassification

These mats are often confused with 7019.62, which is specifically for mats made of rovings that are mechanically bonded. They are also sometimes confused with 7019.12 (rovings) or 7019.11 (chopped strands). The key is that 7019.19 covers the "mat" form (a sheet) rather than the individual strands or rovings themselves.

FAQ

What is the HS code for chopped strand mats (CSM)?

Chopped strand mats are typically classified under HS code 7019.19.

How does 7019.19 differ from 7019.62?

7019.19 covers general mats and threads, whereas 7019.62 is specifically for closed fabrics or mats made of rovings that are mechanically bonded (like needled mats).
