Products classified under Tariff item 2921.29.00.00
1,2-Propylenediamine
1,2-Propylenediamine is a vicinal diamine isomer used in chiral synthesis and epoxy systems. As an acyclic polyamine, it falls under this tariff item for other acyclic polyamines and their derivatives.
2921.29.001,3-Diaminopropane
1,3-Diaminopropane is an acyclic diamine used in curing agents and cross-linking applications. It is not specifically named in other subheadings, so it falls under this tariff item for other acyclic polyamines.
2921.29.001,6-Diaminohexane Dihydrochloride
1,6-Diaminohexane dihydrochloride is the salt of 1,6-diaminohexane, an acyclic polyamine. Per Chapter 29 Note 5(C)(1), inorganic salts of organic compounds are classified with the parent compound, so it falls under this tariff item.
2921.29.00Bis(hexamethylene)triamine
Bis(hexamethylene)triamine is a long-chain acyclic triamine used in high-performance polyamides. It is not specifically named elsewhere, so it falls under this tariff item for other acyclic polyamines.
2921.29.00Cadaverine Hydrochloride
Cadaverine hydrochloride is the salt of 1,5-diaminopentane, an acyclic polyamine. Per Chapter 29 Note 5(C)(1), inorganic salts of organic compounds are classified with the parent compound, so it falls under this tariff item.
2921.29.00Diethylenetriamine (DETA)
Diethylenetriamine (DETA) is a linear acyclic polyamine used primarily as an epoxy resin curing agent. It is not specifically named in other subheadings, so it falls under this tariff item for other acyclic polyamines.
2921.29.00Ethylenediamine
Ethylenediamine is an acyclic polyamine with two primary amine groups connected by an ethylene bridge. It is not specifically named in other subheadings, so it falls under this tariff item for other acyclic polyamines.
2921.29.00Ethylenediamine Dihydrochloride Salt
Ethylenediamine dihydrochloride is the salt form of ethylenediamine, an acyclic polyamine. Per Chapter 29 Note 5(C)(1), inorganic salts of organic compounds are classified with the parent compound, so it falls under this tariff item.
2921.29.00Hexamethylenediamine
Hexamethylenediamine is a straight-chain acyclic diamine used in nylon-6,6 polymer production. It is not specifically named in other subheadings, so it falls under this tariff item for other acyclic polyamines.
