Products classified under HTS 2921.30.30.00
Cyclohexylamine
Cyclohexylamine is a cyclanic monoamine derived from aromatic compounds through hydrogenation processes, featuring a six-membered ring structure with an amine group. It falls under HTS 2921.30.3000 as a cyclanic amine derivative with aromatic origins, used primarily in rubber accelerators and corrosion inhibitors. This classification aligns with chapter 29 notes for amine-function compounds.
N-Cyclohexyl-N'-phenyl-p-phenylenediamine
This rubber antioxidant is a polyamine derivative combining cyclanic and aromatic structures, derived in part from aromatic compounds like aniline. Classified under HTS 2921.30.3000 for cyclanic polyamines with aromatic derivation, used in tire manufacturing. Meets chapter requirements for separate chemically defined compounds.
Dicyclohexylamine
Dicyclohexylamine is a cyclanic polyamine formed by two cyclohexyl groups attached to nitrogen, often derived from aromatic cyclohexane processes. It qualifies under HTS 2921.30.3000 as a derivative salts thereof from aromatic sources, used in epoxy curing agents. Adheres to chapter notes excluding only specific mixtures.
1,3-Bis(aminomethyl)cyclohexane
A cyclanic polyamine with two aminomethyl groups on a cyclohexane ring, derived from aromatic toluene diamine hydrogenations. Falls under HTS 2921.30.3000 for 'other' cyclanic polyamine derivatives from aromatics, used in polyurethane production. Chemically defined per chapter note (a).
Cyclohexanediamine (1,2-Diaminocyclohexane)
1,2-Diaminocyclohexane is a cyclanic polyamine with adjacent amine groups on the ring, partially derived from aromatic o-phenylenediamine. Classified in HTS 2921.30.3000 as 'other' derivatives salts thereof, essential for chiral catalysts. Fits chapter's amine-function scope.
N-Isopropyl-N'-phenyl-p-phenylenediamine
IPPD is a cyclenic/cyclanic hybrid polyamine derivative from aromatic p-phenylenediamine, used as antiozonant in rubber. Under HTS 2921.30.3000 for 'other' aromatic-derived cyclanic amines, chemically defined without excluded additives.
4-Cyclohexylaminophenol
A cyclanic amine derivative with phenolic group, from aromatic aniline, used in dye intermediates. HTS 2921.30.3000 covers as 'other' due to primary amine function and aromatic derivation, per oxygen-function notes.
Cyclohexylaminobenzene
Cyclohexylaminobenzene (N-cyclohexylaniline) is a monoamine with cyclanic and aromatic moieties, derived from aniline. Classifies in HTS 2921.30.3000 as aromatic-derived cyclanic amine.
Bis(4-aminocyclohexyl)methane
A polyamine linking two aminocyclohexyl groups via methylene, from diaminodiphenylmethane. HTS 2921.30.3000 for 'other' cyclanic polyamines aromatic-derived.
1,4-Diaminocyclohexane
Trans-1,4-diaminocyclohexane, cyclanic polyamine from p-phenylenediamine, for epoxy hardeners. HTS 2921.30.3000.
