Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorporates mechanical gyroscope elements
Instruments using physical gyroscopes without optical sensing classify under 9014.20.
If primarily optical fiber cable assembly
Bare optical fiber cables and cables exclude from Chapter 90 instruments per note 1(h).
If for measuring or checking linear dimensions
Optical measuring instruments compete with 9031 per Chapter Note 6, prioritizing measuring function.
