9902.03.30 - 5,5'-Oxybis(2-benzofuran-1,3-dione) (CAS No.1823-59-2) (provided for in subheading 2918.99.43)

This HTS category, 9902.03.30, specifically classifies the chemical compound 5,5'-Oxybis(2-benzofuran-1,3-dione), identified by CAS No. 1823-59-2. This classification falls under Section XXII, which deals with special provisions including temporary legislation and import restrictions. It is important to note that while this is the specific classification for this compound under temporary provisions, its primary classification for general trade purposes is provided for in subheading 2918.99.43, indicating its underlying chemical nature.

As a leaf node within Chapter 99, this category does not have further subdivisions. Its uniqueness lies in its designation as a temporary provision, distinct from the broad categories of live animals found at the beginning of the HTS. The primary function of this classification is to address specific regulatory controls or tariff treatments that apply to this particular chemical substance, rather than to broad classes of goods. Classification here is driven by the precise chemical identity of the imported material.
