Product classification
HS code for Mineral insulation: 6806.90
Minerals, mixtures and articles of heat-insulating, sound-insulating or sound-absorbing mineral materials, other than those of heading no. 6811 or 6812 or of chapter 69.
Classification of mineral insulation under HS 6806.90
Mineral insulation products are classified under HS code 6806.90. This code encompasses mixtures and articles of heat-insulating, sound-insulating, or sound-absorbing mineral materials. The classification is determined by the composition of the material, which typically involves mineral wools such as slag or rock wool or expanded minerals like perlite or vermiculite. Under the Harmonized System, Chapter 68 covers articles of stone and other mineral substances. Heading 6806 is specifically designed for products that provide insulation through their mineral structure. Subheading 6806.90 is the residual category for articles made from these materials that are not specifically listed as slag wool or expanded minerals in their bulk form. This includes finished products like pipe coverings, acoustic panels, and specialized industrial insulation blocks. It is essential that these products do not contain asbestos, as those would be classified under heading 6812. The classification also excludes ceramic products of Chapter 69, which are fired after shaping.

Codes often confused with 6806.90
Common mistake. The most common misclassification is with HS code 7019, which covers glass wool and fiberglass insulation. While they look similar, glass fiber is classified in Chapter 70. Another confusion occurs with 6901.00, which covers bricks and blocks of fossil meals like kieselguhr, which are fired ceramic goods.
Top exporters and importers of HS 680690 (the code used for mineral insulation), 2025
In 2025, the largest exporter of HS 680690 (the code used for mineral insulation) in UN Comtrade data was Germany, with 20% of world exports; the largest importer in UN Comtrade data was the United States, with 11% of world imports.

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).
