9902.06.20 - 2-Cyanopyridine (2-Pyridinecarbonitrile) (CAS No. 100-70-9) (provided for in subheading 2933.39.91)

This HTS classification, 9902.06.20, specifically covers 2-Cyanopyridine, also known as 2-Pyridinecarbonitrile. This chemical compound, identified by CAS Number 100-70-9, falls under the special provisions of Chapter 99, indicating it is subject to temporary legislation or modifications. Its inclusion in this chapter means it is being managed under specific trade agreements or agricultural adjustment act provisions, distinct from its general classification under Chapter 29.

While this category is a leaf node and does not possess direct subcategories at this level, it is crucial to understand its placement within the broader HTS structure. The "provided for in subheading 2933.39.91" notation signifies that the material's primary classification for duty and statistical purposes would typically reside within heading 2933, which covers heterocyclic compounds with nitrogen hetero-atom(s) only. However, its presence in 9902.06.20 indicates that special import rules or restrictions are currently in effect for this specific chemical, overriding or supplementing its standard tariff treatment. Importers must therefore consult both the Chapter 99 provision and the referenced subheading to fully understand all applicable duties, quotas, or other requirements.
