9902.02.95 - Itaconic acid (2-methylidenebutanedioic acid) (CAS No. 97-65-4) (provided for in subheading 2917.19.70)

This HTS category, 9902.02.95, specifically addresses Itaconic acid, also known by its chemical name 2-methylidenebutanedioic acid and identified by CAS No. 97-65-4. This classification falls under Chapter 99, which is reserved for temporary legislation, temporary modifications stemming from trade agreements, and additional import restrictions imposed under Section 22 of the Agricultural Adjustment Act. The designation "provided for in subheading 2917.19.70" indicates that Itaconic acid is a specific substance subject to special tariff treatment or restrictions, separate from its standard classification under Chapter 29.

As a leaf node within Chapter 99, this category does not have further subcategories. Its purpose is to apply unique import provisions to Itaconic acid. Unlike the broad categories of live animals found in earlier chapters (e.g., 0101-0105), this entry pertains to a specific organic chemical compound, highlighting the diverse nature of goods covered by the HTS. The inclusion of Itaconic acid within Chapter 99 signifies that its import may be subject to quotas, higher duty rates, or other specific requirements not applicable to the same chemical when classified under its primary HTS heading.
