Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as part of a multi-component mixture for dye synthesis
Mixtures containing this nitrile diluted for specific azo dye production fall under heterocyclic compounds per Chapter 29 note (h), taking precedence over pure nitriles.
If when dissolved in solvents exceeding safety/transport thresholds
Solutions where solvent renders product suitable for specific industrial use (not just transport) are classified as chemical preparations in Chapter 38, per Chapter 29 note (e).
If halogenated before nitrile group formation, classified by principal function
Halogenated aromatic hydrocarbons take precedence over nitrile function if the compound is primarily identified as a chlorobenzene derivative under Chapter 29 classification rule.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming 99%+ purity and exact chemical identity to avoid misclassification as mixtures under Chapter 38
• Ensure proper UN 3439 hazardous material declaration and packaging compliant with DOT 49 CFR for toxic solid transport
• Include end-use statement if for R&D to qualify for lower duties under HTS 9810.00.60; avoid bulk imports without FDA registration if pharmaceutical intermediate
