Caprolactam from Japan

Caprolactam is a cyclic amide (lactam) with a six-membered ring containing a nitrogen hetero-atom, used primarily as a monomer in the production of nylon 6 polymer. It falls under HTS 2933.79.85.00 as a lactam that is neither specifically named in prior subheadings nor a beta-lactam antibiotic structure. This chemically defined heterocyclic compound with nitrogen hetero-atom only meets Chapter 29 requirements for classification.

Import Tips

Provide detailed chemical composition certificates and CAS number (105-60-2) documentation to verify classification as a lactam

Ensure proper Hazard Communication labeling per GHS standards for skin irritants and reproductive toxins

Verify REACH compliance if transshipping through EU; common misclassification as simple amide rather than lactam
