Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If percarbonate complex rather than periodate
Calcium percarbonates classify under carbonates/peroxocarbonates.
If in rodenticides or disinfectants
Pesticidal goods containing periodates go to Chapter 38.
If bulk chemical preparation for industrial water treatment
Mixed preparations not chemically defined classify as 'other' chemicals.
