HS code for Glass fiber rovings: 7019.12

Glass fibres, (including glass wool), rovings.

Classification of glass fiber rovings under HS 7019.12

Glass fiber rovings are classified under HS code 7019.12. Rovings are defined as a collection of parallel, untwisted continuous filaments or strands gathered into a single bundle. They are a fundamental input for many composite manufacturing processes, including pultrusion, filament winding, and the production of woven rovings. In the Harmonized System, 7019.12 is distinguished from chopped strands (7019.11) and other yarns (7019.13). The distinction is based on the physical form of the fiber: rovings are continuous and lack the twist found in traditional yarns. This classification is critical for manufacturers of fiberglass-reinforced plastics (FRP). If the rovings are subsequently woven into a fabric, the classification shifts to 7019.61. Therefore, 7019.12 is strictly for the raw, continuous roving bundles as they are wound onto bobbins or creels for industrial use. The classification follows GRI 1, as the subheading specifically names \"rovings\" as a distinct category of glass fiber products. These are typically used in high-strength applications where the alignment of the fibers is necessary for structural integrity.

Codes often confused with 7019.12

Common mistake. The most common misclassification is 7019.11, which is for chopped strands (fibers cut to specific short lengths). Another error is 7019.13, which covers glass yarns; the key difference is that yarns are twisted, while rovings are not. Additionally, if the rovings have been woven into a mat or fabric, they must be classified under 7019.61 (woven rovings) rather than the raw material code 7019.12.

Top exporters and importers of HS 701912 (the code used for glass fiber rovings), 2025

In 2025, the largest exporter of HS 701912 (the code used for glass fiber rovings) in UN Comtrade data was China, with 36% of world exports; the largest importer in UN Comtrade data was the United States, with 18% of world imports. Mexico reports $155M of its chapter 70 exports without product detail (confidential), so it may also belong among the top exporters.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. 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).
