9902.04.79 - 1,2 Dicyanobenzene (phthalodinitrile) (CAS No. 91-15-6) (provided for in subheading 2926.90.43)

This HTS category, 9902.04.79, specifically covers 1,2-Dicyanobenzene, also known as phthalodinitrile. Phthalodinitrile is an organic chemical compound with the CAS number 91-15-6. It is important to note that this classification is made "provided for in subheading 2926.90.43," indicating that the material itself is a precursor or component that falls under a broader chemical classification within Chapter 29 of the HTS. This provision within Chapter 99 signifies a temporary modification or special treatment applied to this particular chemical.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its placement under Section XXII: Special Classification Provisions, and specifically within Chapter 99: Temporary legislation; temporary modifications proclaimed pursuant to trade agreements legislation; additional import restrictions proclaimed pursuant to section 22 of the Agricultural Adjustment Act, as amended, highlights that it is subject to specific temporary tariff treatments or restrictions, rather than a general commodity classification. This distinguishes it from the broad categories of general goods like live animals found at the same hierarchical level (e.g., 0101, 0102). The focus here is on the specific application of trade policy to this chemical.
