Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed exclusively for laboratory use
Lab-specific analytical instruments fall under dedicated laboratory subheadings in 9027.80.
If classified as a basic agricultural machine part
Simple probes without independent analysis capability may be treated as parts of farming machinery.
If for non-chemical measuring functions like moisture only
Instruments measuring physical properties without chemical analysis go to other measuring devices in 9031.
