Product Overview A solid state relay (SSR) classified under HS Code 853641 is an electronic switching device that uses semiconductor components to perform the function of an electromechanical relay without moving parts. These devices are designed to control high-voltage and high-current electrical circuits with minimal electrical noise and enhanced durability. Typical physical specifications include compact form factors with rated voltages ranging from 24V to 600V AC or DC, and current ratings from 1A up to 100A or higher, depending on design and application. SSRs are manufactured through precision semiconductor fabrication processes ensuring high reliability, fast switching speeds, and resistance to vibration and shock. The HS Code 853641 encompasses solid state relays and similar solid state devices used for switching, subdivided into types based on their electrical characteristics and applications, including photo-coupled SSRs and zero-cross switching SSRs. Commercially, these relays are integral in automation systems across food service equipment, retail checkout systems, and industrial processing machinery, providing silent operation and enhanced lifespan over traditional relays. Their market positioning is centered on reliability, low maintenance, and compliance with stringent safety standards, making them essential components in international electrical and automation supply chains. HS Code Classification & Trade Specifications Solid state relays fall under the HS Code 853641, where ‘85’ denotes electrical machinery and equipment, ‘36’ specifies electrical switches, and ‘41’ identifies solid state relays and similar solid state devices for switching purposes. This 6-digit code provides a standardized international classification facilitating customs clearance and trade compliance. The classification is justified by the SSR’s function as a semiconductor switching device replacing mechanical relays, conforming to the World Customs Organization’s Harmonized System guidelines. In trade logistics, SSRs are typically packaged in anti-static, moisture-resistant materials such as sealed plastic trays or blister packs to prevent electrostatic discharge and environmental damage during transit. Preservation methods include humidity control and temperature regulation to maintain device integrity. Shipping requirements often specify compliance with international electrical component handling protocols, including proper labeling and material safety data sheets. Quality standards applicable to SSRs include IEC 60947-4-3 and UL 508 compliance, ensuring performance consistency and safety. This classification and trade framework support accurate tariff application, regulatory adherence, and efficient global distribution within the electrical components sector.
