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.

Alternative Classifications

This product could be classified differently depending on its characteristics or intended use.

2924.29Lower: 19% vs 37.5%

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.

3901.10.10Higher: 44% vs 37.5%

If pre-polymerized into polyamide resin

Polymerized form shifts to Chapter 39 polymers of nylon or polyamides, not pure Chapter 29 compounds.

2942.00Lower: 16.2% vs 37.5%

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
