HS Code 7019.19 – Glass fibres; (including glass wool), threads and mats, other than mechanically or chemically bonded mats
HS code 7019.19 is the 6-digit subheading for glass fibres, (including glass wool), threads and mats, other than mechanically or chemically bonded mats. It is used for continuous filament glass rovings, chopped strand glass fibers, glass fiber yarns, glass wool insulation and glass fiber mats (non-bonded).
What HS 7019.19 covers
This category encompasses a broad range of primary glass fiber products crucial for various industrial applications, excluding those specifically designed for mechanical or chemical bonding into fabrics. It includes raw glass fibers, often in continuous filament form, chopped strands, and non-woven mats that are not yet integrated into more complex textiles. These materials are fundamental building blocks for composites, insulation, and reinforcement. Major importers and exporters are typically industrial nations with strong manufacturing sectors, particularly in automotive, aerospace, construction, and electronics. Key things to know include the importance of fiber diameter, surface treatment (sizing), and alkali content, which dictate their suitability for different resin systems and end-use environments. The global trade in these basic forms of glass fiber is driven by demand for lightweight, high-strength, and corrosion-resistant materials, making them a vital component in modern engineering and infrastructure projects worldwide.

Codes often confused with 7019.19
Common mistake. This code can be confused with 701931 (rovings) or 701932 (chopped strands) if the "other than mechanically or chemically bonded mats" distinction is overlooked, as those codes are more specific for certain forms. It's also distinct from 70196x and 70197x which cover bonded fabrics.
Top exporters and importers of HS code 701919, 2025
In 2025, the largest exporter of HS code 701919 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. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
