12-Aminododecanoic Acid Lactam
12-Aminododecanoic acid lactam, also known as ε-caprolactam's higher homolog (laurolactam), is a heterocyclic lactam with a 12-membered nitrogen-containing ring formed from 12-aminododecanoic acid. It falls under HTS 2933.79.40.00 as a specific 'other lactam' in the lactams subheading of heterocyclic compounds with nitrogen hetero-atoms only. This pure chemical compound is used primarily as a monomer in nylon polymer production.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported as a cyclic amide without emphasis on lactam structure
Could be seen as 'other carboxylic acids with additional oxygen function' if ring structure not recognized as heterocyclic lactam.
If pre-polymerized into polyamide resin
Polymerized form shifts to Chapter 39 polymers of nylon or polyamides, not pure Chapter 29 compounds.
If containing unesterified hydroxyl groups or as sugar derivative
Organic derivatives of specified heterocycles, but only if chemically modified beyond simple lactam structure.

Import Tips & Compliance
• Provide Certificate of Analysis (CoA) confirming purity and identity as 12-aminododecanoic acid lactam to avoid misclassification
• Declare CAS number 5200-86-8 on entry documents; ensure proper hazardous material labeling if shipped in bulk
• Verify REACH compliance for EU imports and TSCA registration for US; common pitfall is incorrect Chapter 29 subheading
