Products classified under HTS 2929.10.80
Methylene Diphenyl Diisocyanate (MDI)
MDI is a diisocyanate compound featuring two isocyanate (-N=C=O) functional groups attached to a diphenylmethane backbone, classifying it under HTS 2929.10.80 as an 'other' isocyanate with nitrogen function. It is primarily used in the production of polyurethane foams, coatings, and adhesives.
Isophorone Diisocyanate (IPDI)
IPDI is a cycloaliphatic diisocyanate with two -NCO groups, falling under HTS 2929.10.80 as an 'other' isocyanate due to its distinct nitrogen function. It is valued for light-stable polyurethane coatings and elastomers in automotive and optical applications.
Hexamethylene Diisocyanate (HDI)
HDI is an aliphatic diisocyanate with the formula OCNC6H12NCO, classified in HTS 2929.10.80 as an other isocyanate compound with nitrogen function. Commonly used in high-performance, UV-resistant polyurethane clearcoats for vehicles and wood finishes.
4,4'-Methylenebis(phenyl isocyanate)
This aromatic diisocyanate, also known as pure MDI, contains two isocyanate groups linked by methylenebis(phenyl), qualifying under HTS 2929.10.80 for other isocyanates. Essential raw material for rigid polyurethane foams in insulation panels.
Norbornane Diisocyanate
A bicyclic aliphatic diisocyanate derived from norbornane, classified under HTS 2929.10.80 as other isocyanates with nitrogen function. Used in specialty polyurethanes requiring high thermal stability and hydrolytic resistance.
1,5-Naphthalene Diisocyanate (NDI)
NDI features two isocyanate groups on a naphthalene ring system, falling under HTS 2929.10.80 as other isocyanates. Primarily employed in spandex fiber production and high-strength polyurethane elastomers.
p-Phenylene Diisocyanate (PPDI)
PPDI is a para-substituted benzene ring with two isocyanate groups, classified in HTS 2929.10.80 as other isocyanates with nitrogen function. Utilized in advanced polyurea coatings and composite materials.
