Product classification
HS code for Glass fiber mat: 7019.15
Glass fibres, (including glass wool), chemically bonded mats.
Classification of glass fiber mat under HS 7019.15
Glass fiber mats are classified under HS code 7019.15, which pertains to glass fibers (including glass wool) and articles thereof, specifically chemically bonded mats. This classification is guided by the material's structural form and the method of manufacture. Chapter 70 covers glass and glassware, and heading 7019 is dedicated to glass fibers and their products. The sub-heading 7019.15 is designated for mats where the glass fibers are held together by a chemical binder, such as a resin or adhesive, rather than through mechanical interlocking. These mats are typically used in composite manufacturing, insulation, and roofing applications. The classification process requires identifying that the product is made of glass filaments and that the primary bonding mechanism is chemical. This distinguishes it from woven fabrics or mechanically bonded products like needle-punched mats. The technical specifications of the binder and the density of the mat are secondary to the primary classification of the bonding method under the 7019 hierarchy.

Codes often confused with 7019.15
Common mistake. Glass fiber mats are often misclassified under HS code 7019.14, which is reserved for mechanically bonded mats (such as needle-loomed or stitched mats). The difference is purely the manufacturing process: 7019.15 requires a chemical agent. Additionally, importers sometimes mistakenly use HS code 6806.10, which covers slag wool, rock wool, and similar mineral wools. While glass wool is technically a mineral fiber, the Harmonized System specifically directs glass-based fibers to heading 7019.
Top exporters and importers of HS 701915 (the code used for glass fiber mat), 2025
In 2025, the largest exporter of HS 701915 (the code used for glass fiber mat) in UN Comtrade data was China, with 39% of world exports; the largest importer in UN Comtrade data was the United States, with 17% 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).
