Product classification
HS code for Soundproofing mineral panels: 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 soundproofing mineral panels under HS 6806.90
Soundproofing mineral panels are classified under HS code 6806.90. This code falls under Chapter 68, which covers articles of stone, plaster, cement, asbestos, mica, or similar materials. Specifically, heading 6806 includes slag-wool, rock-wool, and similar mineral wools, as well as expanded mineral materials and mixtures of heat-insulating, sound-insulating, or sound-absorbing mineral materials. The classification 6806.90 is a residual category for mineral-based insulating articles that are not specifically mentioned in other subheadings. These panels are manufactured by bonding mineral fibers or expanded minerals with binders to create rigid or semi-rigid boards. Their primary utility is their ability to dampen acoustic energy or provide thermal resistance. To fall under this code, the panels must be predominantly composed of mineral substances. This classification is vital for the construction industry, as it distinguishes mineral-based safety materials from plastic or wood-based alternatives which have different fire-rating and environmental regulations.

Codes often confused with 6806.90
Common mistake. A frequent misclassification occurs with HS code 3921, which covers cellular plastic panels (like polyurethane foam). While foam panels are used for soundproofing, they are chemically distinct from mineral panels. Another common error is using HS code 4411, which applies to fiberboard of wood or other ligneous materials. If the panel is made of wood fibers rather than mineral wool, it must be moved to Chapter 44. Additionally, panels made of asbestos-cement or cellulose-fiber cement are classified under 6811. Importers must verify the base material (mineral vs. organic) to ensure the correct application of 6806.90.
Top exporters and importers of HS 680690 (the code used for soundproofing mineral panels), 2025
In 2025, the largest exporter of HS 680690 (the code used for soundproofing mineral panels) 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. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).

Questions about soundproofing mineral panels
What is the HS code for Soundproofing mineral panels?
The HS code for Soundproofing mineral panels is 680690 (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). The HS code for these mineral-based insulating articles is 6806.90.
How do I classify Soundproofing mineral panels for customs?
Soundproofing mineral panels is classified under HS code 680690 — 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. This is a 6-digit subheading level code.
Are fiberglass panels classified here?
Yes, panels made of glass wool (fiberglass) for sound insulation are typically classified under heading 7019, but certain mineral-based mixtures may fall under 6806 depending on their exact composition.
Which countries are the top exporters of soundproofing mineral panels (HS 680690)?
In 2025, the top exporters of HS 680690 (the code used for soundproofing mineral panels) in UN Comtrade data were Germany ($363M, 20% of world exports), the United States ($296M) and Japan ($177M).
