Products classified under HTS 2929.10.80.90
Methylene Diphenyl Diisocyanate (MDI)
Methylene diphenyl diisocyanate (MDI) is a diisocyanate compound featuring two isocyanate (-N=C=O) groups attached to a diphenylmethane structure, classifying it under HTS 2929.10.80.90 as an 'other' isocyanate with nitrogen function. It is primarily used in the production of polyurethane foams, coatings, and adhesives.
Toluene Diisocyanate (TDI) 80/20 Mixture
TDI 80/20 is an 80:20 mixture of 2,4- and 2,6-toluene diisocyanate isomers, qualifying as 'other' isocyanates under HTS 2929.10.80.90 per Chapter 29 note (b) for isomer mixtures. Widely used for flexible slabstock polyurethane foams.
Xylidene Diisocyanate (XDI)
Xylidene diisocyanate (XDI), or xylylene diisocyanate, is a meta-xylylene-based diisocyanate classified in HTS 2929.10.80.90 as other isocyanates. It produces polyureas and coatings with excellent adhesion properties.
Methylenedi-p-tolyl Diisocyanate (MDT)
Methylenedi-p-tolyl diisocyanate (MDT or DET) contains two p-tolyl isocyanate groups linked by methylene, qualifying under HTS 2929.10.80.90 as other isocyanates. Used in specialty polyurethane elastomers.
Isophorone Diisocyanate (IPDI)
Isophorone diisocyanate (IPDI) is a cycloaliphatic diisocyanate with two -NCO groups, falling under HTS 2929.10.80.90 as an 'other' isocyanate compound with nitrogen function per Chapter 29 notes. It is valued for light-stable polyurethane coatings and elastomers.
Hexamethylene Diisocyanate (HDI)
Hexamethylene diisocyanate (HDI) is an aliphatic diisocyanate with the formula OCNC6H12NCO, classified in HTS 2929.10.80.90 as an 'other' isocyanate per Chapter 29 nitrogen function provisions. It produces flexible, UV-resistant polyurethanes for automotive clearcoats.
p-Phenylene Diisocyanate (PPDI)
p-Phenylene diisocyanate (PPDI), or 1,4-diisocyanatobenzene, contains two isocyanate groups on a benzene ring, classifying under HTS 2929.10.80.90 as other aromatic isocyanates. Used in high-temperature resistant polyurethanes and spandex fibers.
Naphthalene Diisocyanate (NDI)
Naphthalene-1,5-diisocyanate (NDI) features two -NCO groups on a naphthalene backbone, falling under HTS 2929.10.80.90 as other isocyanates with nitrogen function. Applied in crystalline polyurethanes for engineering plastics.
