Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If classified by cyclic alcohol precursor structure
Some might misclassify under cyclic alcohols (2906) but lactam nitrogen-function takes precedence per Chapter 29 notes
If containing >1% sugar-derived impurities
Organic derivatives with sugar components fall under 2940-2942; pure caprolactam remains 2933 lactam
If for carboxylic acid derivatives if hydrolyzed form
Hydrolyzed to 6-aminocaproic acid would shift to carboxylic acid classification in 2918

Import Tips & Compliance
• 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
