Glass fibres, (including glass wool), rovings.
Classification of fiberglass rovings under HS 7019.12
Fiberglass rovings are classified under HS code 7019.12. Rovings are a specific form of glass fiber product consisting of a collection of continuous filaments gathered into a single strand without an intentional twist. This classification is determined by the physical state of the glass fiber at the time of export. Under the Harmonized System, heading 7019 covers glass fibers and their products. The sub-heading 7019.12 is specifically reserved for rovings. These are primary products used in various manufacturing processes like pultrusion, filament winding, and the production of woven rovings. The absence of a twist is the defining characteristic that separates rovings from yarns. Customs authorities look for the continuous nature of the filaments and the lack of mechanical twisting to confirm this classification. Because rovings serve as the foundational material for many composite reinforcements, their classification is strictly monitored to ensure they are not confused with processed fabrics or chopped fibers. The filaments in a roving are typically bundled in a parallel fashion, allowing for high tensile strength in specific directions, which is a key identifier during physical inspection by customs officers.

Codes often confused with 7019.12
Common mistake. Fiberglass rovings are most commonly misclassified as fiberglass yarn under 7019.13. The technical difference is the twist; yarns are twisted, while rovings are not. They are also sometimes confused with chopped strands (7019.11), which are short, cut lengths of fiber rather than continuous strands. Furthermore, if the rovings have been woven into a fabric, they must be classified under 7019.61 or 7019.62, as 7019.12 only covers the raw, unwoven strand.
Top exporters and importers of HS 701912 (the code used for fiberglass rovings), 2025
In 2025, the largest exporter of HS 701912 (the code used for fiberglass 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).

What is the difference between a roving and a yarn in HS classification?
In the context of HS code 7019, rovings (7019.12) are untwisted continuous strands, whereas yarns (7019.13) have a definite mechanical twist applied to the fibers.
Which countries are the top exporters of fiberglass rovings (HS 701912)?
In 2025, the top exporters of HS 701912 (the code used for fiberglass rovings) in UN Comtrade data were China ($484M, 36% of world exports), Egypt ($118M) and Bahrain (about $93M). World exports came to about $1.4B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Mexico reports $155M of its chapter 70 exports without product detail (confidential), so it may also belong among the top exporters.
Which countries are the top importers of fiberglass rovings (HS 701912)?
