Thermal pad Hs Code

Thermal pad harmonized system code

Product Overview Thermal pads classified under HS Code 680690 are specialized materials primarily used for thermal management applications in various industrial sectors. Defined as composite sheets composed of thermally conductive but electrically insulating materials, these pads facilitate heat dissipation between electronic components and heat sinks or other cooling devices. Typically, they exhibit precise physical specifications including thickness ranges from 0.25 mm to 5 mm, thermal conductivity values spanning 1.0 to 6.0 W/m·K, and are manufactured through advanced processing techniques such as calendaring, lamination, or die-cutting to ensure uniform density and surface flatness. HS Code 680690 encompasses a range of thermal interface materials categorized by composition—such as silicone-based, graphite-enhanced, or ceramic-filled pads—each designed to meet specific thermal performance criteria. Commercially, these thermal pads are indispensable in electronics manufacturing, automotive component assembly, and industrial machinery maintenance, where reliable heat transfer improves operational efficiency and component longevity. Their competitive advantage lies in offering consistent thermal resistance, mechanical compliance, and ease of installation, positioning them as critical consumables within the global supply chain for thermal management solutions. HS Code Classification & Trade Specifications The complete HS Code classification for thermal pads is 680690, where Chapter 68 covers “Articles of Stone, Plaster, Cement, Asbestos, Mica or Similar Materials,” Heading 6806 pertains to “Articles of Mica,” and Subheading 680690 designates “Other Articles of Mica or Similar Materials.” Thermal pads fall under this specific code due to their mica or mica-like composite mineral content that imparts essential thermal insulation and conductivity properties. Trade compliance necessitates adherence to standardized packaging norms—typically moisture-resistant, anti-static trays or sealed foil pouches—to preserve material integrity during transit. Shipping conditions often require temperature-controlled environments to prevent degradation of polymeric binders. Quality standards align with IEC 60672-3 and UL 94 certifications to verify thermal conductivity, electrical insulation, and flammability ratings. Documentation must reflect precise product specifications, batch traceability, and conformity with WTO trade agreements to ensure seamless customs clearance. This classification framework facilitates accurate tariff application, import/export licensing, and regulatory compliance for international buyers, customs brokers, and trade compliance professionals engaged in the global distribution of thermal management materials.
