Product classification
HS code for Fiberglass mesh: 7019.66
Glass fibres, open woven fabrics of a width exceeding 30cm.
Classification of fiberglass mesh under HS 7019.66
Fiberglass mesh is classified under HS code 7019.66, which specifically covers glass fibers and articles thereof, specifically open woven fabrics with a width exceeding 30 cm. This classification is determined by the material composition and the structural weave of the product. Chapter 70 of the Harmonized System governs glass and glassware, while heading 7019 is dedicated to glass fibers (including glass wool) and articles made from these fibers. The subheading 7019.66 is applied because the mesh is an "open woven" fabric, meaning the warp and weft yarns are spaced to create a grid-like pattern rather than a solid surface. For a product to qualify under this specific code, it must be wider than 30 cm; otherwise, it would fall under the narrow fabric category. Even when the mesh is treated with alkali-resistant resins or other coatings for use in construction (such as EIFS or drywall reinforcement), it remains under this code because the glass fiber provides the essential character of the article according to General Interpretative Rule 3(b).

- Chomarat Rovicore (open weave variants)
Codes often confused with 7019.66
Common mistake. Fiberglass mesh is frequently confused with HS code 7019.61, which is reserved for "closed" woven fabrics where the yarns are tightly packed. Another common error is using HS code 7019.65, which is only for narrow fabrics with a width of 30 cm or less. In some instances, importers mistakenly use 3926.90 for plastic-coated mesh, but if the glass fiber is the primary component by weight and function, 7019.66 is the correct designation.
Top exporters and importers of HS 701966 (the code used for fiberglass mesh), 2025
In 2025, the largest exporter of HS 701966 (the code used for fiberglass mesh) in UN Comtrade data was Czechia, with 23% of world exports; the largest importer in UN Comtrade data was Germany, with 15% 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).

Questions about fiberglass mesh
What is the HS code for Fiberglass mesh?
The HS code for Fiberglass mesh is 701966 (Glass fibres; open woven fabrics of a width exceeding 30cm). The standard HS code for fiberglass mesh that is an open woven fabric with a width greater than 30 cm is 7019.66.
How do I classify Fiberglass mesh for customs?
Fiberglass mesh is classified under HS code 701966 — Glass fibres; open woven fabrics of a width exceeding 30cm. This is a 6-digit subheading level code.
Does the coating on the mesh change the HS code?
Generally, no. Most fiberglass mesh is coated with an acrylic or SBR latex to provide alkali resistance. As long as the glass fiber remains the essential component, it is still classified under 7019.66.
Which countries are the top exporters of fiberglass mesh (HS 701966)?
