Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If primarily for measuring or checking optical properties like spectrum
Chapter note directs optical measuring instruments to 9031 instead of general 9013.
If designed for telecom wavelength division multiplexing testing
Machines for reception/transmission of telecom line signals classify under 8517.
If incorporates electrical oscilloscopes for signal analysis
Instruments with principal electrical measuring function go to 9030.

Import Tips & Compliance
• Distinguish from electrical analyzers by emphasizing optical diffraction components in documentation
• Provide wavelength range specs (e.g
• 400-1700nm) to support 9013 classification
• Check for encryption if includes software, triggering BIS export controls
