Subheadings
Products classified under HTS 2929.90.50
N-Isopropyl-N-phenyl-p-phenylenediamine
This is a chemically defined organic compound featuring nitrogen functions including an amine group linked to aromatic rings. Classified under HTS 2929.90.50 as it contains 'other nitrogen function' groups not covered by more specific nitrogen-function headings in Chapter 29. Commonly used as an antidegradant in rubber production.
4,4'-Methylenebis(2-chloroaniline)
A di-amine compound with other nitrogen functions and chlorinated aromatic rings, used as a curing agent in polyurethane production. Falls under 2929.90.50 as 'other' nitrogen-function compounds outside specific amine headings. The chloro substituents are compound derivatives covered by Chapter 29 notes.
Diphenylguanidine
An organic compound with guanidine nitrogen functionality used as a rubber accelerator. Classified in 2929.90.50 as it features 'other nitrogen function' beyond specific amide, imine, or hydrazine categories. Meets Chapter 29 requirement for chemically defined compounds.
N-Cyclohexyl-N'-phenyl-p-phenylenediamine
Antioxidant for rubber and plastics featuring diarylamine nitrogen functions. HTS 2929.90.50 covers this as 'other nitrogen function' compound with mixed aromatic-aliphatic amine structure. Chemically defined per Chapter 29 note (a).
Melamine (Cyanurotriamide)
Triazine compound with multiple amide nitrogen functions used in resin production. Classifies under 2929.90.50 as 'other' nitrogen-function compound not fitting specific triazine or amide headings. Excluded from Chapter 30 immunological products.
6-Amino-1-naphthalenesulfonic Acid
Naphthalenic amine with sulfonic acid group used in dye intermediates. Falls under 2929.90.50 as primary nitrogen-function compound despite sulfonation, per Chapter 29 notes on compound derivatives. Not classified as sulfonated hydrocarbon.
Benzotriazole
Fused heterocyclic compound with triazole nitrogen functions used as corrosion inhibitor. Classified 2929.90.50 as 'other nitrogen function' since not fitting specific heterocycle headings 2933-2934. Chemically defined benzotriazole base.
p-Phenylenediamine Sulfate
Salt of aromatic diamine with sulfuric acid, used in dye and rubber chemicals. HTS 2929.90.50 per Chapter 29 note on inorganic salts of organic nitrogen compounds classified with the organic base. Meets 'other nitrogen function' criteria.
1,3,5-Tris(2-hydroxyethyl)hexahydro-1,3,5-triazine
