2929.10.10.00 - Toluenediisocyanates (unmixed)

This HTS classification, 2929.10.10.00, specifically covers toluenediisocyanates (TDIs) when they are unmixed. This means the classification applies to pure toluenediisocyanates, without being combined with other chemical substances or isomers in a mixture. These are organic compounds characterized by the presence of two isocyanate (-NCO) functional groups attached to a toluene ring.

It is crucial to distinguish this category from its siblings. For instance, 2929.10.15.00 covers mixtures of the 2,4- and 2,6-toluenediisocyanates isomers, whereas this node is for the unmixed forms. Other sibling categories, such as 2929.10.20.00, include distinct diisocyanates like bitolylene diisocyanate (TODI) and xylene diisocyanate, highlighting the specificity of this category to toluenediisocyanates only.

As this is a leaf node, there are no further subcategories. Classification within 2929.10.10.00 is determined by the purity and specific identity as unmixed toluenediisocyanates. This precise classification ensures accurate tariff application based on the chemical nature and composition of the imported or exported product, aligning with the broader scope of isocyanates under Chapter 29.
