HS Code for Soundproofing mineral panels

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.

Products Included

• Rock wool acoustic panels
• Slag wool ceiling tiles
• Mineral fiber sound-absorbing boards
• Acoustic mineral wool batts
• Composite mineral insulation panels
• Exfoliated vermiculite soundproofing sheets

Common Misclassification

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.

FAQ

What is the HS code for soundproofing mineral panels?

The HS code for these mineral-based insulating articles is 6806.90.

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.
