HS code for Fiberglass insulation: 7019.80
Glass fibres, glass wool and articles thereof.
Classification of fiberglass insulation under HS 7019.80
Fiberglass insulation is classified under HS code 7019.80, which encompasses glass wool and articles made from glass wool. The classification process involves distinguishing glass wool from other mineral wools. Glass wool is produced by melting glass and then fiberizing it through a centrifugal or attenuation process, resulting in a mass of fine, entangled fibers. Under the Harmonized System, this specific morphology—resembling natural wool—is the primary factor for classification under 7019.80. This code includes both the raw wool and finished articles like batts or blankets used for thermal or acoustic insulation. It is important to note that for a product to be classified here, the glass fiber content must be the component that gives the article its essential character. These materials are widely used in the construction industry to improve energy efficiency and provide sound dampening in residential and commercial structures. The classification remains consistent whether the insulation is provided in rolls, slabs, or loose-fill form, provided the material is glass wool.

Codes often confused with 7019.80
Common mistake. Fiberglass insulation is often misclassified under HS code 6806.10, which covers slag wool, rock wool, and similar mineral wools. While they serve the same purpose, 6806.10 is for wools derived from stone or metallurgical slag, whereas 7019.80 is strictly for wool derived from glass. It may also be confused with 7019.90 if the product is a highly specialized glass fiber article that no longer resembles "wool."

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).
