Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If isomer mix not predominantly xylene-based
Only specific isomers named; others go to residual isocyanates.
If reacted to low-molecular-weight polyurethane
Partially polymerized forms become epoxide resins or polyurethanes in Chapter 39.
If crude form with petroleum impurities
Chapter 29 excludes crude hydrocarbons; impure distillates may revert to Chapter 27.

Xylene Diisocyanate (XDI)
Xylene diisocyanate (XDI) is a specific aromatic diisocyanate compound with two isocyanate (-NCO) functional groups attached to a xylene ring, explicitly listed under HTS 2929.10.20.00. It is primarily used in the production of polyurethane foams, coatings, and adhesives due to its reactivity in forming polymer chains. This chemically defined organic compound falls under Chapter 29 heading 2929 for compounds with other nitrogen functions, specifically isocyanates.
Bitolylene Diisocyanate (TODI)
Bitolylene diisocyanate (TODI), also known as 3,3'-bitolylene-4,4'-diisocyanate, is an aromatic diisocyanate explicitly named in HTS 2929.10.20.00 due to its two isocyanate groups on a bitolyl structure. It serves as a key raw material in high-performance polyurethane elastomers and coatings, valued for thermal stability. As a separate chemically defined organic compound with nitrogen functions, it fits Chapter 29's scope for isocyanates.
o-Tolyl Isocyanate
o-Isocyanic acid, o-tolyl ester (o-tolyl isocyanate) is a monoisocyanate with the formula C6H4(CH3)NCO, explicitly covered under HTS 2929.10.20.00 for its isocyanate nitrogen function. It acts as an intermediate in pharmaceutical synthesis and agrochemicals, reacting to form ureas and carbamates. This fits Chapter 29 as a separate chemically defined compound with 'other nitrogen function' per heading 2929.
Purified 2,4-TDI (Xylene Diisocyanate Isomer)
Purified 2,4-xylene diisocyanate (often synonymous with TDI in trade), a specific isomer listed under HTS 2929.10.20.00 for its diisocyanate structure. Essential for rigid polyurethane foams in insulation panels. Qualifies as separate organic compound under Chapter 29 notes (a).
o-Tolyl Isocyanate Stabilized with 0.05% Benzoyl Chloride
Stabilized o-tolyl isocyanate containing 0.05% benzoyl chloride as a preservative, permitted under HTS 2929.10.20.00 per Chapter note (f) for added stabilizers necessary for transport. Used in fine chemical synthesis for herbicides. Retains classification as the base isocyanate compound.
Xylene Diisocyanate in Toluene Solution (50% for Transport)
50% xylene diisocyanate dissolved in toluene for safe transport, classifiable under HTS 2929.10.20.00 per Chapter note (e) as a normal method for safety without specific use suitability. Reduces vapor pressure for safer shipping in polyurethane supply chain. Still treated as the named isocyanate compound.
