Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If standard distillation equipment for chemical processing
Non-isotopic distillation apparatus falls under chemical reaction/distillation in 8419.
If smaller lab units for R&D not production scale
Laboratory-scale distillers classify as lab machinery in 8419.
