HS Code 7019.12 – Glass fibres; (including glass wool), rovings
HS code 7019.12 is the 6-digit subheading for glass fibres, (including glass wool), rovings. It is used for direct rovings for pultrusion, assembled rovings for filament winding, spray-up rovings, woven roving fabrics and multi-end rovings.
What HS 7019.12 covers
This category specifically covers glass fibers, including glass wool, in the form of rovings. Rovings are bundles of continuous glass fiber strands, often wound onto spools, designed for high-strength reinforcement applications. They are a fundamental material in the composites industry, providing exceptional tensile strength, stiffness, and dimensional stability. These materials are essential for creating lightweight yet robust structures. Importers are primarily manufacturers of large composite products such as wind turbine blades, boat hulls, automotive parts, pipes, and other structural components. Exporters are specialized glass fiber manufacturers with advanced drawing and winding capabilities. Critical factors for trade include the type of glass (e.g., E-glass, S-glass), the sizing chemistry for optimal resin compatibility, and the linear density (tex) of the roving, all of which dictate performance in the final product.

Codes often confused with 7019.12
Common mistake. Often confused with 701913 (yarns) or 701914 (mats) if the specific continuous, bundled form is not clearly identified. Also, 3920 (other plates, sheets, film, foil, strip, of plastics) if the roving is pre-impregnated with resin.
Top exporters and importers of HS code 701912, 2025
In 2025, the largest exporter of HS code 701912 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 products fall under HS code 701912?
Direct rovings for pultrusion, assembled rovings for filament winding, spray-up rovings, woven roving fabrics, multi-end rovings, single-end rovings, panel rovings
What are common misclassifications for HS code 701912?
Often confused with 701913 (yarns) or 701914 (mats) if the specific continuous, bundled form is not clearly identified. Also, 3920 (other plates, sheets, film, foil, strip, of plastics) if the roving is pre-impregnated with resin.
Which countries are the top exporters of goods under HS code 701912?
In 2025, the top exporters of HS code 701912 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 goods under HS code 701912?
In 2025, the top importers of HS code 701912 in UN Comtrade data were the United States ($262M, 18% of world imports), Germany ($127M) and India ($78M). World imports came to about $1.5B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.
How is HS code 701912 structured?
HS code 701912 is a 6-digit subheading under the Harmonized System. The first 2 digits (70) identify the chapter, digits 3-4 (19) identify the heading, and digits 5-6 (12) specify the subheading. This code is standardized globally by the World Customs Organization.
