Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If designed as a general industrial filtering or purifying equipment
Purifiers not specifically for acetylene generators may shift to Chapter 84 for centrifugal/pressure filters.
If for ceramic purifier components sold separately
Ceramic labware or crucibles for gas purification classify under Chapter 69 by material.
