Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If adapted for softer materials like plastics
Brinell method unsuitable for non-metals directs to other materials subheading.
If incorporating laser measuring optics as primary function
Chapter note 7 prioritizes measuring optical instruments to 9031 or 9013 over mechanical testers.
If principally a hydraulic testing valve system
Note 1(g) excludes valves/appliances of 8481 even if used in testing setups.
