HS code for Glass wool (chopped): 7019.11
Glass fibres, (including glass wool), chopped strands, of a length of not more than 50mm.
Classification of glass wool (chopped) under HS 7019.11
Chopped glass wool is classified under HS code 7019.11. Heading 7019 covers glass fibers (including glass wool) and articles thereof. Within this heading, the 7019.1x series deals with slivers, rovings, yarn, and chopped strands. Subheading 7019.11 is specifically designated for chopped strands that have a length of not more than 50 mm. These are often used as reinforcement materials in plastics, composites, or specialized cement. The classification is strictly based on the physical form (chopped strands) and the precise measurement of the fiber length. If the fibers exceed 50 mm, they would fall under a different subheading. Glass wool in this context refers to the fibrous state of the glass rather than the bulk insulation material, which is often classified elsewhere depending on its form. The manufacturing process involves extruding molten glass through fine orifices and then mechanically chopping the resulting filaments into uniform lengths.

Codes often confused with 7019.11
Common mistake. The most common misclassification occurs with 7019.12, which is reserved for rovings (continuous strands). Another error is classifying chopped strands under 7019.39, which covers glass wool in the form of mats or thin sheets. If the glass wool is processed into insulation batts or blankets, it may be confused with 7019.90. It is vital to measure the strand length, as any chopped strand over 50 mm moves from 7019.11 to 7019.19.

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).
