Products classified under HTS 6806.90.00.10
Acoustical Mineral Wool Ceiling Panels
These rigid panels made from compressed mineral wool (rock wool) are designed for ceiling installation in offices and auditoriums to absorb sound waves and reduce echo. They fall under HTS 6806.90.00.10 as sound-absorbing articles of mineral materials, specifically classified as acoustical pads and boards, excluding those of headings 6811 or 6812. The porous structure traps sound energy, providing high Noise Reduction Coefficient (NRC) ratings.
Sound-Absorbing Vermiculite Wall Panels
Panels composed of exfoliated vermiculite mixed with mineral binders form lightweight, fire-resistant boards for wall applications in recording studios and theaters. Classified under HTS 6806.90.00.10 as acoustical boards of expanded mineral materials for their sound-insulating properties. They meet acoustical standards without using excluded materials from other chapters.
Rock Wool Acoustical Stage Backdrop Boards
High-density rock wool boards used behind stages in concert venues to absorb mid-to-high frequency sounds and prevent feedback. They qualify under HTS 6806.90.00.10 as sound-absorbing articles of mineral wools, distinct from mixtures of heading 6811. Custom perforations enhance their acoustical performance.
Foamed Slag Sound Barrier Panels
Panels produced from expanded foamed slag, a byproduct of steel production, offering durable sound absorption for highway noise barriers. Falls under HTS 6806.90.00.10 as acoustical boards of expanded mineral materials, not covered by Chapter 69 exclusions. Their cellular structure provides excellent sound dampening.
Expanded Clay Acoustical Partition Boards
Lightweight boards made from expanded clay (LECA) granules bound with mineral adhesives for office partitions that reduce noise transmission. Classified in HTS 6806.90.00.10 for sound-absorbing articles of expanded clays, excluding coated textiles or Chapter 69 items. Ideal for modular interior construction.
Mineral Wool Studio Acoustic Bass Traps
Corner-mounted trapezoidal pads of high-density mineral wool designed to absorb low-frequency bass in music recording studios. HTS 6806.90.00.10 covers these as acoustical pads of mineral wools for sound absorption. Fabric-wrapped but mineral core determines classification.
Exfoliated Vermiculite Fire-Rated Sound Panels
Fire-resistant panels using exfoliated vermiculite for sound control in commercial kitchens and mechanical rooms. Under HTS 6806.90.00.10 as acoustical boards with dual heat/sound insulation from expanded minerals. Exceeds 1-hour fire rating.
Mixed Mineral Wool Conference Room Tiles
Suspended ceiling tiles blending rock wool and expanded slag for optimal reverberation control in meeting spaces. HTS 6806.90.00.10 for mixtures of sound-absorbing mineral materials as acoustical boards. High light reflectance surface.
Expanded Perlite Acoustical Screen Inserts
Inserts for room divider screens made from expanded perlite granules providing portable sound diffusion. Classed under HTS 6806.90.00.10 as sound-absorbing pads of expanded mineral material. Lightweight for easy repositioning.
Mineral Wool Home Theater Wall Pads
DIY wall-mountable pads of rock wool for home cinema setups absorbing surround sound reflections. HTS 6806.90.00.10 as consumer acoustical pads of mineral wool. Fabric covered with mineral core.
