Ceramic-Based Thick-Film Hybrid Circuit for Automotive Sensors from Japan

This printed circuit board features a ceramic base with thick-film conductive and resistive layers screen-printed and fired for high-temperature applications in automotive sensors. It falls under HTS 8534.00.00.85 due to its ceramic substrate and classification as a printed circuit 'having a ceramic base' for reliable performance in harsh environments. Commonly used in engine management and ABS systems.

Import Tips

Verify ceramic base material certification (e.g

alumina 96%) as Customs requires proof it's not organic substrate like FR4

Include test reports showing thick-film firing process to distinguish from etched circuits under 8534 other subheadings

Avoid misclassification as hybrid ICs (8542); provide assembly diagrams showing printed circuit as primary component
