Product classification
HS code for Fiberglass mats: 7019.19
Glass fibres, (including glass wool), threads and mats, other than mechanically or chemically bonded mats.
Classification of fiberglass mats under HS 7019.19
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.

Codes often confused with 7019.19
Common mistake. 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.
Top exporters and importers of HS 701919 (the code used for fiberglass mats), 2025
In 2025, the largest exporter of HS 701919 (the code used for fiberglass mats) in UN Comtrade data was the United States, with 22% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
