Product classification
HS code for Glass fiber products: 7019.90
Glass fibres, n.e.c. in heading no. 7019.
Classification of glass fiber products under HS 7019.90
HS code 7019.90 serves as the residual category for glass fiber products that are not specifically enumerated in the other subheadings of heading 7019. Glass fibers, including glass wool, are versatile materials used for insulation, filtration, and reinforcement. Heading 7019 is structured to first identify primary forms like rovings, chopped strands, and yarns, followed by woven and non-woven fabrics. Subheading 7019.90 captures finished articles or semi-finished products that do not fit the definitions of rovings, yarns, or specific fabrics. This includes specialized acoustic panels, certain types of pipe insulation, or composite reinforcement mats that do not meet the technical specifications of the preceding codes. Classification here requires a thorough analysis of the manufacturing process—whether the fibers are mechanically bonded, chemically bonded, or simply compressed—to ensure they do not fall under the more specific codes for mats, veils, or woven rovings. Under GRI 1, if a product is made of glass fibers but is not a fabric or a primary strand, 7019.90 is the appropriate classification.

Codes often confused with 7019.90
Common mistake. Glass fiber products are often misclassified under 7019.11 through 7019.19 if the customs broker mistakes a finished article for raw fiber strands. They are also frequently confused with 6806.10 (slags wool or rock wool). It is critical to verify that the material is indeed glass fiber. Furthermore, if the product is a woven fabric, it must be classified under 7019.61 through 7019.69 depending on the weave and weight, rather than the residual 7019.90.

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).
