HS code for Glass wool insulation: 7019.80
Glass fibres, glass wool and articles thereof.
Classification of glass wool insulation under HS 7019.80
Glass wool insulation is classified under HS code 7019.80. This code covers glass fibers and articles made from those fibers, specifically glass wool. Glass wool is produced by spinning or drawing molten glass into fine filaments, which are then gathered into a mass resembling wool. This material is widely used for thermal and acoustic insulation in construction and industrial applications. The classification under 7019.80 is appropriate because it encompasses both the bulk wool and finished articles made from it, such as batts, rolls, or boards. It is distinguished from other mineral wools by its chemical composition, being derived from glass-forming silicates. The Harmonized System specifically groups glass fibers and their products in heading 7019, and the 7019.80 subheading is the designated location for wool-like glass fiber products. This classification remains consistent regardless of whether the glass wool is faced with aluminum foil, paper, or plastic, provided the glass wool provides the essential character of the insulation.

Codes often confused with 7019.80
Common mistake. The most frequent misclassification is with HS code 6806.10, which covers slag wool, rock wool, and similar mineral wools. While they look similar, glass wool is chemically distinct and must stay in Chapter 70. Another error involves classifying glass wool fabrics or veils under 7019.60 or 7019.30; however, if the material has the characteristic 'wool' loft and density for insulation, 7019.80 is the correct destination.

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).
