Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as standalone photodiodes
General photosensitive semiconductor devices classified in Chapter 85, not as instrument-specific parts.
If for other optical measuring instruments
Parts of non-chemical analysis optical instruments like lasers fall under 9013.
If for subheading 9027.10 instruments
Parts specific to gas/liquid chromatographs have separate statistical suffix.
