Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pure aluminum chloride without catalytic formulation
Unformulated inorganic chlorides classified as basic chemicals in Chapter 28
If activated for specific pesticide synthesis
Specialized pesticide reaction initiators fall under activated carbon preparations
If supported on precious metal carriers
Precious metal catalyst supports change the subheading classification
