9902.06.26 - 2-Methylquinoline (Quinaldine) (CAS No. 91-63-4) (provided for in subheading 2933.49.70)

This HTS classification, 9902.06.26, pertains specifically to 2-Methylquinoline, also known as Quinaldine, identified by CAS Number 91-63-4. This compound is a heterocyclic organic molecule with distinct chemical properties. Its inclusion under Chapter 99 signifies a temporary legislative provision or modification, as indicated by its reference to subheading 2933.49.70 within the broader HTS framework.

As a leaf node within Chapter 99, this category does not subdivide further. Its specificity lies in the direct classification of 2-Methylquinoline under a temporary measure. This distinguishes it from other potential entries in the HTS, which might cover chemicals with different molecular structures, broader chemical families, or items subject to permanent tariff rates rather than temporary modifications. The classification of 2-Methylquinoline here is directly linked to its chemical identity and the specific trade or legislative context it falls under within the temporary provisions of Chapter 99.
