Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If triazole portion determines principal function
Specific azole compounds may be provided for earlier in 2933.99.
If when imported as 50% solution in industrial formulation
Finished chemical preparations containing <95% active shift to heading 3819.
If anti-freeze preparations containing benzotriazole
Antifreeze preparations specifically excluded and classified in 3820.
