9902.01.19 - Medium oil fractions containing more than 50 percent by weight of isohexadecane (CAS No. 93685-80-4) (provided for in subheading 2710.19.90)

This HTS category, 9902.01.19, specifically covers medium oil fractions of petroleum or bituminous minerals that are characterized by containing more than 50 percent by weight of isohexadecane (CAS No. 93685-80-4). These products are typically derived from crude oil refining processes and fall under temporary legislation or special classification provisions, as indicated by their placement in Chapter 99.

Distinguishing this category from its broader sibling categories within Section XXII, such as those related to live animals or other agricultural products, is crucial. While those siblings deal with distinct commodity groups, 9902.01.19 focuses on a very specific chemical composition of a petroleum derivative. It is important to note that the provision for these goods is found within subheading 2710.19.90 of the HTS, indicating their underlying classification as petroleum oils, but the 9902 code signifies a temporary or special tariff treatment.

As this is a leaf node within the HTS database, there are no further subcategories that subdivide this specific classification. Therefore, the classification of a product under 9902.01.19 hinges entirely on meeting the stated compositional requirement of containing more than 50 percent isohexadecane and being a medium oil fraction. Importers must ensure accurate laboratory analysis confirms this specific percentage to correctly apply this temporary tariff provision.
