Import Tips

• Include GC-MS analysis confirming ε-Caprolactam as principal isomer; mixtures of isomers may require different classification

• Declare exact melting point (68-70°C) and declare as 'not for retail sale' to avoid Chapter 38 mixtures classification

• Check country-specific anti-dumping duties; provide mill test certificate tracing origin back to manufacturer
