Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If considered 1,3-Diphenylurea derivative
Specific provision for simpler diphenylurea precedes this 'other' category.
If classified as aromatic ketone derivative
If carbonyl function considered principal over amide function.
If as anti-dusting preparation
Products with anti-dusting agents per chapter note (g) may shift to mixtures.

Import Tips & Compliance
• Document flake production process to confirm it doesn't render product suitable for specific use beyond transport
• Melting point verification (around 80°C) helps distinguish from similar melting ureas
• Customs may require solubility tests in organic solvents to confirm identity
