HS code for Fiberglass mat (chemically bonded): 7019.15
Glass fibres, (including glass wool), chemically bonded mats.
Classification of fiberglass mat (chemically bonded) under HS 7019.15
Chemically bonded fiberglass mats are classified under HS code 7019.15. This classification is part of the 7019 heading, which covers glass fibers and their derivative products. Within the sub-structure of 7019, mats are distinguished by the method used to hold the glass fibers together. Chemical bonding involves the application of a binder, typically in the form of a liquid resin (emulsion) or a dry powder, which is then cured to create a cohesive sheet or mat. This process is common for chopped strand mats (CSM) used in the reinforced plastics industry. The binder ensures the mat maintains its shape during handling and provides compatibility with the resins used in composite manufacturing. Under the Harmonized System, it is crucial to distinguish these from mechanically bonded mats, as the manufacturing process and the resulting physical properties differ significantly. The classification 7019.15 specifically targets these resin-bonded materials, ensuring they are separated from woven fabrics or mechanically entangled mats. These mats are widely used in boat building, automotive parts, and storage tanks where a uniform reinforcement layer is required.

Codes often confused with 7019.15
Common mistake. The most common misclassification is with 7019.14, which is for mechanically bonded mats (like needled mats). It can also be confused with 7019.13 (rovings) or 7019.19 (other non-woven glass fiber products). If the mat is woven, it must move to the 7019.6x series.
Top exporters and importers of HS 701915 (the code used for fiberglass mat (chemically bonded)), 2025
In 2025, the largest exporter of HS 701915 (the code used for fiberglass mat (chemically bonded)) 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).
