Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incorrectly declared as non-heterocyclic aromatic compound
Benzotriazole's fused heterocyclic ring structure requires Chapter 29 classification over halogenated/sulfonated aromatics in 2903.
If for industrial use as drawing/ stamping compound ingredient
When supplied in preparations for drawing/stamping metal, classified as industrial finishing preparations rather than pure chemical.
