Acoustic panels Hs Code

Acoustic panels harmonized system code

Product Overview Acoustic panels classified under HS Code 680690 are engineered materials primarily composed of mineral-based substances, used to attenuate sound and improve acoustic environments. These panels exhibit defined physical specifications, typically featuring thicknesses ranging from 10 mm to 50 mm, densities between 150 to 300 kg/m³, and surface finishes that may include perforated facings or fabric coverings. Manufactured through advanced processing techniques such as mineral wool bonding or fiber reinforcement, these panels maintain dimensional stability, fire resistance, and sound absorption coefficients (NRC) commonly between 0.6 and 0.95. HS Code 680690 encompasses various subcategories, including mineral wool panels, stone wool acoustic boards, and composite acoustic slabs. Commercially, these products are widely applied in food service facilities, retail outlets, and food processing plants to control noise levels, enhance worker safety, and comply with occupational health regulations. Their value proposition lies in combining effective sound dampening with durability and compliance with hygiene standards, positioning them as essential components in industrial and commercial acoustic management systems. HS Code Classification & Trade Specifications The HS Code 680690 is situated within Chapter 68 (Articles of stone, plaster, cement, asbestos, mica or similar materials), specifically under Heading 6806, which covers “Slag wool, rock wool and similar mineral wools; exfoliated vermiculite, expanded clays, foamed slag and similar expanded mineral materials; mixtures and articles of heat-insulating, sound-insulating or sound-absorbing mineral materials.” The subheading 680690 designates “Other articles” not elsewhere specified within this heading, capturing specialized acoustic panels. Classification under this code is justified by the mineral composition and intended acoustic function of the product. Standard trade practices involve packaging panels in moisture-resistant, palletized bundles with protective wrapping to prevent damage during transport. Preservation methods include humidity control and use of desiccants to maintain product integrity. Shipping typically adheres to international standards for handling bulk mineral goods, ensuring compliance with WTO trade facilitation agreements. Quality standards aligned with ISO 354 (measurement of sound absorption) and ASTM C665 (mineral fiber insulation) are often mandated, supporting consistent customs valuation and regulatory conformity across international markets.
