Telecom Rectifier Module Printed Circuit Board
Printed circuit assembly containing rectifier circuits from subheading 8504.40, optimized for AC-to-DC conversion in central office telecom power systems. Used in telephone exchanges and network hubs for reliable power delivery. Falls under 8504.90.65.00 due to its telecom-specific application.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as complete rectifier unit, not just PCA
Assembled static converters with housing classify as complete articles under 8504.40.
If integral to transmission apparatus for TV/radio
Power supply PCAs designed into transmission equipment fall under 8525.
If for parts of telephone/telecom sets specifically
Narrower heading for telephone apparatus parts may apply over general converter parts.
