Import Tips & Compliance
• Submit spectroscopic data verifying 2,5-isomer (CAS 3547-16-0) to avoid misclassification with 2,4-isomer
• Ensure packaging complies with UN 3439 hazardous material regulations for nitrile compounds
• Declare intended use as chemical intermediate, not final pesticide, to prevent reclassification
