Acoustical Mineral Wool Ceiling Panels from Canada
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.

Import Tips
• Verify the product is composed primarily of mineral wool or expanded mineral materials to qualify under Chapter 68; provide lab test reports confirming sound absorption properties
• Ensure labeling includes material composition and fire ratings (e.g
• Class A per ASTM E84) as required for building materials; common pitfall is misclassifying fiberglass products
• Obtain certificates of origin for preferential duty treatment and comply with EPA formaldehyde emission standards if applicable to binders used
